What A.8.30 outsourced development asks you to control
A.8.30 Outsourced development asks the organization to direct, monitor and review the work that an external party performs when it builds or changes systems for you. In plain terms, you keep the decisions about what gets built and how it is secured, and you keep enough visibility to confirm that the supplier actually followed those decisions. The control does not ask you to build everything in-house, but it does ask you to remain accountable for code, configuration and access that you do not directly control. The 2013 edition covered the same ground under A.14.2.7, and ISO/IEC 27002:2022 traces the two together in its correspondence table, so existing supplier oversight work carries over.
The risk is concrete. A software house may write code with weak input validation, pull in libraries you never reviewed, leave a default administrator account in a deployed environment, or hold credentials for your production systems on laptops you cannot inspect. The control is hard to meet for three reasons: the contract often says little about secure development, you rarely see the supplier's daily work, and evidence such as test results or dependency lists tends to arrive at the end of a sprint or after go-live. Before signing, confirm which secure development requirements, code review practices, testing and vulnerability handling the contract obliges the supplier to provide, and who on your side receives and accepts that evidence.
A.8.30 sits next to three controls that cover the same supplier relationship from different angles. A.5.20 Addressing information security within supplier agreements is where the security obligations are written into the contract. A.5.21 Managing information security in the ICT supply chain covers the wider chain of suppliers and their own suppliers. A.8.29 Security testing in development and acceptance is where you define and run the tests that decide whether a delivered system is accepted. A.8.30 is the operational link: it requires you to watch the outsourced work while it happens and to review what it produces. An auditor will usually expect to trace a single supplier from contract clause to test result to acceptance decision, so map those four controls together rather than treating them as separate projects.
Which outsourced development work is in scope for A.8.30
Scope under A.8.30 depends on who writes the code, what it touches and how close supplier staff get to production. Each decision below changes how much direction, monitoring and review the organization must evidence, so settle them in writing before the first supplier commit.
Custom development suppliers
Firms that build software to your specification are the core case for A.8.30. Their work is usually delivered under a statement of work, and that document is where requirements, coding standards and handover obligations should be written down. Check whether the contract gives you the right to review design decisions and the code itself, not only the finished release. Ask the supplier to name the repositories and environments their team will use, because those become the evidence you review.
Managed and offshore development teams
A supplier that supplies a dedicated team, often in another country, adds questions about who joins the team, how turnover is handled and which legal and data protection rules apply to their work. Effort rises because you must verify the team's access, training and offboarding, not only the firm's policies. Ask for the list of named individuals, their access grants and a rule that removes access within an agreed period after they leave the project.
Contractors working as individuals
Freelancers and short-term contractors are often engaged directly rather than through a firm, which leaves the organization holding the contract and the accountability. Each individual needs the same secure development expectations, confidentiality terms and access reviews as a supplier team. The effort is mostly administrative but easy to miss, so keep an inventory of every individual with commit or deployment rights and tie each one to a signed agreement.
Suppliers of components inside your system
Some outsourced work is not building features at all. A supplier may provide libraries, frameworks, SDKs or plugins that end up in your product. These components need the same direction as custom code, and their origin, versions and licenses must be known. Ask suppliers for a software bill of materials for each delivered component and for notice of known vulnerabilities, so the component inventory stays accurate over time.
New build versus upgrade and maintenance
New builds bring the widest scope because every design, coding and testing decision is still open. Upgrades and maintenance on existing systems are narrower but often touch live code paths and security settings. Review each change request against the same outsourced development requirements, and do not let a maintenance ticket skip acceptance testing. Agree in advance which change types need security review and which can follow a lighter path.
Supplier staff with production access
When supplier staff can reach production systems or production data, the scope widens into access control, logging and change management. This is the highest-risk scoping decision because it links A.8.30 to privileged access and production environment controls. Confirm whether supplier accounts are separate, time-limited and logged, and whether any production access requires your approval. Where access is not needed, remove it rather than documenting it as acceptable.
How an assessor tests outsourced development controls
This table sets out what an assessor typically does for A.8.30, what evidence they ask to see, and where outsourced development programs most often fall short. Read each row as a test the organization should be able to pass before the audit starts, not as a checklist the assessor will hand over in advance.
| Test area | Evidence requested | Common findings |
|---|---|---|
| Review supplier contracts and security clauses | Signed contracts or statements of work for each development supplier, with security requirements, change control and termination terms | Contracts silent on secure coding, testing or incident notification; security terms present in the template but missing from signed agreements |
| Sample outsourced change records | A selection of supplier-delivered changes or releases with request, review, approval and merge records traced to the supplier | Changes merged with no recorded internal review; supplier commits that cannot be traced to an approved request |
| Check acceptance test results for sampled releases | Acceptance test plans, security test output and sign-off by the organization before each release reached production | No acceptance evidence for sampled releases; sign-off given by the supplier rather than the organization |
| Confirm the organization reviewed supplier security testing output | Dated reviews of supplier scan or test reports, with findings tracked to closure or formally accepted as risk | Supplier reports received and filed but never reviewed; open findings with no owner or decision |
| Confirm rights to audit are written down and used | Audit clauses in contracts, records of any audits, questionnaires or assessments performed on the supplier | Audit right written but never exercised; no evidence the organization requested supplier evidence on a schedule |
| Check that supplier access is recorded | Access lists for repositories, build systems and environments used by supplier staff, with approval and removal dates | Shared accounts used by supplier teams; supplier access still active after the engagement ended |
How to implement A.8.30 step by step
This sequence turns outsourced development from an informal arrangement into a controlled process, with each step leaving a record that shows the organization directs, monitors and reviews its suppliers. Work through it in order, because each artifact feeds the next step and an assessor will expect to trace them back to one another.
Inventory outsourced development activities
Start by listing every place where a third party builds, modifies, configures or deploys systems or software for the organization. Include contractors, offshore teams, agencies, low-code vendors, managed service providers that write scripts, and open-source contributors paid to work on internal code. For each entry, record the supplier, the systems involved, the data they can reach and the business owner who accepts their work. The output is a supplier development register that is reviewed on a set schedule and whenever a new engagement starts. An assessor will ask for this register first, so check that it matches what engineering teams actually use.
Write security requirements into contracts and statements of work
For each supplier on the register, set out security requirements in the statement of work or master agreement before work begins. Cover secure coding expectations, the security testing the supplier must perform, vulnerability notification timelines, handling of credentials and personal data, ownership of code and documentation, and the supplier's obligation to follow the organization's security policies. Link these terms to the supplier agreement controls in A.5.20 and to the broader supply chain approach in A.5.21. The output is a signed agreement containing a security schedule. Ask legal and security to review the schedule together, and confirm that the terms are enforceable in the jurisdictions where the supplier operates.
Onboard suppliers with defined access rules
Before a supplier engineer touches any system, grant access only to the repositories, environments and accounts named in the statement of work. Require individual accounts, multi-factor authentication, and removal of access when a person leaves the project. Keep supplier accounts separate from employee accounts so that their activity is easy to identify in logs. The output is an access matrix that lists each supplier, each person or group, the resources they can reach and the approver. Review the matrix whenever the scope changes, and compare it against the supplier register so that no active engagement lacks an entry.
Control code on the organization's own repositories
Host the code on repositories the organization controls, not on a supplier's tooling. Protect the main branches so that only defined roles can merge, block direct pushes to production branches, and keep force pushes disabled unless someone explicitly allows them. The GitLab Community Edition documentation describes protected branches that support these settings. Require review by an internal reviewer before any supplier change is merged. The output is a branch protection configuration and a merge log showing who approved each change. Confirm the settings with a screenshot or configuration export, because assessors often ask to see the setting itself rather than a written policy.
Define security testing and acceptance criteria
Agree in writing what the supplier's deliverable must pass before the organization accepts it. Typical criteria include a clean scan from static analysis, no open high-severity findings from dynamic testing, a current software bill of materials, and documented test results for the agreed security requirements. Static analysis tools such as Semgrep Community Edition can run in the supplier's pipeline and in the organization's pipeline, and OWASP Dependency-Track can track components and known vulnerabilities from CycloneDX SBOMs. Trivy can produce or scan SBOMs for containers and dependencies. The output is a written acceptance checklist and the test reports for each release. Link this step to A.8.29, which covers security testing at acceptance.
Review supplier performance on a recurring schedule
Hold periodic reviews with each supplier that cover open findings, late or failed security tests, access changes, incidents involving supplier staff and any changes to the supplier's own subcontractors. Record the attendees, the findings, the decisions and the owner of each action. Where a supplier has missed a requirement, document the corrective action and the date it was verified closed. The output is a review record for each supplier and each period. An assessor will sample these records to confirm that monitoring happens in practice, so schedule the reviews in the calendar and keep the minutes.
Exercise rights to audit and close the cycle
Confirm that the contract gives the organization the right to audit or review the supplier's security practices, and state how that right is used. Options include reviewing the supplier's own assessment reports, sending questionnaires, requesting evidence of secure development training and, where the contract allows, performing on-site or remote audits. Record the audit scope, the findings and the agreed remediation. At the end of each engagement, revoke supplier access, archive the repositories or transfer them, and close the register entry with a final acceptance record. The output is an audit record and an offboarding checklist. Together with the earlier artifacts, these show an assessor a complete chain from contract to closure.
Evidence that satisfies A.8.30 and how to keep it current
A.8.30 is tested through records that show the organization directed and watched its outsourced development, not through a single document. The cards below cover six artifacts an assessor typically asks for, and each one needs refreshing between audits so the record matches what the supplier is doing today. No single item on this list is sufficient on its own.
Signed contracts with security terms
The contract is the first place the organization sets its expectations for the supplier. Check that it names security requirements, secure development duties, subcontractor rules, breach notification and the supplier's obligation to fix defects found in acceptance. Keep a register that links each development contract to its current version, owner and renewal date, and review it when the statement of work changes. Ask counsel to confirm that the clauses survive termination where code or data must be returned.
Supplier security requirements
These are the security requirements the organization sets for the work before it starts, such as secure coding expectations, authentication standards, logging and dependency rules. A.8.30 asks the organization to direct the work, so the requirements should be written down, versioned and handed to the supplier with the statement of work. Review them after each major release or incident and record the reason for any change.
Acceptance test records
Acceptance testing shows whether delivered code meets the agreed security requirements before the organization takes it into service. Keep the test plan, results, defects raised, retests and the decision to accept. Link each acceptance record to the release tag or build it covers, so an assessor can trace a production version back to the test that approved it. Related work on security testing sits under A.8.29.
Code review and merge records
Review and merge history from the organization's own repository shows who approved supplier code and whether it passed through protected branches. In GitLab Community Edition, protected branches can block direct pushes and keep force pushes disabled, which makes the merge trail reliable. Export merge request approvals and branch protection settings on a schedule, and check that supplier accounts cannot approve their own work.
Supplier audit or assessment reports
Independent reports, such as a supplier's own certificate or a security assessment by the organization, show how the supplier runs its controls. Record the scope, the date, the assessor and any exceptions, then track remediation of each finding. Refresh the review on a fixed cadence set by supplier risk, and confirm the rights to audit are still in the contract. Only the independent assessor issues the report, so the organization's own review should be kept separate from it.
Access logs for supplier accounts
Supplier engineers often reach repositories, build systems and environments through named accounts. Log their sign-ins, privilege grants, repository access and removals, and review them against the contract and the active project roster. Remove supplier access when a project ends and keep the removal record. Confirm the logging and retention periods with your own log platform, since those settings vary by deployment.
What meeting A.8.30 costs in money and effort
This table lists each cost component of directing and reviewing outsourced development, who is paid for it, whether it recurs, and what moves it. Use it to frame a request for quotes, because no price or duration is published for these components and every figure depends on the contracts, suppliers and systems in scope.
| Cost component | One-time or recurring | What drives it up or down | How to keep it down |
|---|---|---|---|
| Tooling and licenses | Recurring | Number of repositories, pipelines and suppliers under review. Commercial scanners and SBOM platforms are priced by their own models. Open-source options such as GitLab Community Edition, Semgrep Community Edition, OWASP Dependency-Track and Trivy remove license spend but not staff time. | Confirm each tool's license terms and feature limits before adoption. Self-host where your environment allows, and ask any vendor for the license scope in writing. |
| Engineering time to set requirements and gates | One-time, with periodic review | Number of applications built or acquired, how many security requirements each one needs, and how many gates (design review, code review, security test, acceptance) the organization defines. | Start from one standard requirements set reused across projects. Tie gates to existing change and release steps instead of creating new ones. |
| Contract drafting and legal review | One-time per contract, with renewals | Number of outsourced suppliers, whether the contract template already covers security obligations, and how much negotiation the supplier demands on audit and evidence rights. | Keep a standard security schedule for development work. Ask legal to pre-approve fallback positions for audit rights and evidence delivery. |
| Supplier evidence upkeep | Recurring | Frequency of deliveries, number of supplier teams, and whether evidence arrives in a usable format such as SBOMs, test reports and vulnerability records. | Require machine-readable outputs (for example CycloneDX SBOMs) and fixed delivery points in the contract. Store evidence in one shared location. |
| External security testing or review | Recurring or per release | Application risk, size and number of releases, and whether the organization tests suppliers' code itself or relies on suppliers' test reports. | Scope tests to high-risk components and changed code. Ask suppliers for their own test reports before commissioning a separate review. |
| Auditor sampling time | Recurring, per audit cycle | Number of outsourced projects the auditor samples and how complete the contracts, acceptance records and supplier evidence are when sampled. | Keep one indexed record per outsourced project. Prepare the evidence before the audit so sampling does not turn into a search. |
Open-source tools that produce A.8.30 evidence
A.8.30 asks the organization to direct, monitor and review outsourced development, so the evidence has to come from the repositories, pipelines and component inventories that the supplier works in. The four tools below each produce one kind of that evidence, and none of them proves on its own that a supplier followed the contract. Confirm each capability in your own environment before you cite it in an audit file.
Protected branches in GitLab
GitLab Community Edition (MIT) lets maintainers restrict which roles can push or merge to a branch, and setting push access to no one blocks direct pushes to a protected branch. Force pushes stay disabled unless someone explicitly allows them. Export the branch protection settings and the audit history as evidence that supplier changes reach the main line only through reviewed merge requests. Confirm which settings are available in the edition and version you run, because some controls, such as approval rules, may depend on the tier. This card does not show who approved a change in substance.
Code scanning in CI/CD with Semgrep
Semgrep Community Edition (LGPL-2.1-only) scans code in languages including C/C++, C#, Go, Java, JavaScript, TypeScript, Python, Ruby, Rust, PHP, Kotlin, Swift and Terraform, using community or custom rules. Running it in the pipeline on every supplier merge request produces scan logs that show what was checked and what was flagged. Check which languages in your codebase are covered by rules you trust, and record how findings were triaged. A clean scan does not show that the code meets your security requirements or that acceptance testing happened.
Component tracking with Dependency-Track
OWASP Dependency-Track (Apache-2.0) consumes and produces CycloneDX SBOMs and VEX, and identifies components with known vulnerabilities, outdated or modified components and license risk. It tracks license use by component using SPDX license IDs. Use it to show which third-party libraries a supplier delivered, which ones carry open findings, and where license obligations need legal review. Confirm that your supplier delivers SBOMs in the agreed format, because the tool can only report on the components it receives. It does not assess whether the supplier's own code is secure.
SBOM generation and scanning with Trivy
Trivy (Apache-2.0) identifies the OS packages and software dependencies in a target and can output them as a software bill of materials. It can also scan an existing SBOM, which helps when a supplier provides its own inventory and you want an independent check. Run it against the supplier's build artifacts or images at delivery and keep the generated SBOM with the release record. Confirm which package ecosystems and artifact types your build uses are detected, since a missed ecosystem leaves a gap in the inventory. Trivy output does not prove the supplier's contract terms were met.
Who owns A.8.30 work: your team, a partner and the auditor
Your organization remains accountable for A.8.30 even when a supplier writes the code. The control asks you to direct, monitor and review outsourced development, so the decisions that give that direction have to be made and recorded by your people. Contracts, acceptance and supplier risk are the core of that ownership, and they cannot be handed to a consultant or the supplier itself.
- Contract terms: Your legal and procurement staff agree the security requirements, audit rights, incident notification duties and code ownership terms with the developer before work starts.
- Acceptance decisions: Named staff decide whether delivered code passes the security acceptance criteria, and they keep the signed record of that decision.
- Supplier risk: Your risk owner rates each development supplier, tracks its findings and decides whether to accept, mitigate or exit a risk.
- Direction and monitoring: Your technical lead sets the secure development requirements and reviews supplier progress against them at agreed points.
- Evidence custody: Your team stores the supplier's reports, test results and access records in a system you control.
Check that each of these duties has a named owner and that the contract gives you the right to inspect the supplier's work.
An implementation partner can help you build the technical side of A.8.30 so that outsourced work produces usable evidence. DeployOpen plans, implements and documents self-hosted open-source platforms inside your own infrastructure, and it prepares systems and evidence for assessment. It does not decide your acceptance outcomes, sign supplier contracts or issue audit reports.
- Repositories and access: Configure protected branches and review rules in your self-hosted code platform so that supplier changes need an authorized approval before they merge.
- Pipelines: Build CI/CD stages that run static analysis, dependency checks and software bill of materials generation on every supplier change.
- Evidence templates: Prepare forms and report formats that capture who approved each change, which tests ran and what was accepted or rejected.
- Test setup: Stand up staging environments and test data that let your team run acceptance testing without touching production.
- Limits of the role: The partner prepares systems and evidence. Your staff sign the acceptance decisions, and the auditor independently tests the result.
Confirm in writing which deliverables the partner owns, which are yours and what the partner will not produce.
An independent auditor or accredited certification body tests whether your A.8.30 controls operate as described and issues the report or certificate. Under ISO/IEC 17021-1, certification bodies must be impartial, so the people who design or write evidence for you should not also be the people who judge it. This separation is where independence draws the line.
- Independent testing: The auditor samples supplier contracts, acceptance records and pipeline logs and checks them against your own documented procedures.
- Report or certificate: Only the auditor or certification body issues the audit output, whether that is a certificate or a SOC 2 report from a CPA firm.
- Evidence authorship: Evidence can be generated by tools and prepared by your staff or a partner, but the auditor will expect to see it produced in the normal course of operations, not created for the audit.
- Conflicts of interest: Ask the auditor whether any firm that designed your controls is excluded from judging them.
- Scope questions: The auditor determines whether outsourced development falls inside your certificate scope.
Before engaging anyone, ask the certification body how it handles consultancy conflicts and which evidence it will accept.
Some A.8.30 work is commonly outsourced, and some must stay in-house. The line is set by accountability: you can delegate preparation, but you cannot delegate direction, decisions or ownership of the risk. Clear allocation avoids the common gap where each party assumes another is watching the supplier.
- Commonly outsourced: Pipeline configuration, evidence templates, security tool setup, staging environments and documentation of tooling.
- Commonly outsourced to the supplier: Writing the code, running its own unit and security tests, and producing software bill of materials for its deliverables.
- Must stay in-house: Signing contracts, deciding on acceptance, approving supplier risk exceptions and owning the policy that governs outsourced development.
- Must stay independent: Judging whether the controls work, which belongs to the auditor.
- Ask for in a quote: A responsibility matrix that names who performs, approves and retains each A.8.30 activity.
Review the matrix with your compliance lead before work begins, because gaps between roles are where assessors usually find nonconformities.
Where outsourced development controls usually fall short
Most failures under A.8.30 are not exotic. They come from gaps in the paperwork and handoffs between the organization and its suppliers: what the contract demands, what gets tested before release, who can reach the code and systems, and whether anyone reviews what comes back. Each card below names one gap, how to close it, and the evidence an assessor will ask to see.
Contracts that omit security requirements
Statements of work often describe features and deadlines but say nothing about secure coding, vulnerability handling, logging or secure hosting. A.8.30 expects the organization to direct the supplier's work, which starts in the contract. Check that the agreement references the security requirements from A.8.26, names the secure development standards the supplier must follow, and sets out how defects and vulnerabilities are reported. The evidence is the signed contract and the security schedule attached to it, with a named owner on each clause.
Acceptance testing detached from the release
Teams often run acceptance tests against a demo build or a test branch, then accept a production release that differs from what was tested. The result is a sign-off that proves nothing about the code that goes live. Link each acceptance test run to a specific build identifier and commit, and include security test results (scanning, misuse cases, configuration checks) in the acceptance criteria as described under A.8.29. Evidence includes the signed acceptance record, the test report and the version hash it references.
Supplier access that is never reviewed
Supplier engineers are often granted repository, cloud or pipeline access at kickoff and keep it long after the work ends. Access should follow the same rules as internal staff: named individuals, least privilege, multi-factor authentication and removal at contract end. Review the supplier accounts on a fixed schedule and compare them against the current contract. The evidence is the access list with approval dates, periodic review records and deprovisioning tickets. Protected branches in GitLab Community Edition can restrict which roles may push or merge, which limits supplier write access to what the contract allows.
Unclear rights to audit the supplier
Many contracts give the organization a right to receive reports but not a right to verify them. When a security problem appears, the organization then has no contractual basis to inspect the supplier's practices or request evidence. Agree in advance on the audit scope, notice periods, who pays for the audit, whether supplier independent assessments may replace an on-site review, and what happens if the supplier refuses. Evidence is the audit clause itself, the register of past requests and the supplier's responses.
Supplier code merged without review
Code delivered in archives or pushed straight into a shared branch can bypass the organization's own review and scanning. Require that all supplier code enters through the organization's repository, goes through a reviewed merge request, and is scanned before merge. Semgrep Community Edition can run these checks in CI/CD pipelines across many languages, and Dependency-Track can track the components and licenses the supplier introduces, using a CycloneDX SBOM. Evidence includes merge request approvals, scan results and the SBOM for each delivered release.
No record of supplier components
Outsourced projects often end with a codebase whose open-source dependencies nobody has listed. When a vulnerability is published, the organization cannot tell whether it is exposed. Require the supplier to deliver a software bill of materials with each release and check it against the organization's own scan. Trivy can identify OS packages and dependencies and can also scan existing SBOMs. Evidence is the delivered SBOM, the scan output and the record of follow-up on any findings.
Questions buyers ask about A.8.30 cost, effort and outside help
How much effort does A.8.30 add for a team that uses one development supplier?
For a single supplier, the effort is mostly recurring oversight rather than a large one-time build. The organization must name who directs the supplier's work, agree the security requirements, review what the supplier delivers and keep records of those reviews. Effort rises with the number of releases, the sensitivity of the system and how much of the code the supplier writes. A team with one supplier and a small, well-defined backlog can often run this through existing change and acceptance routines. Ask your team to estimate hours per month for contract review, requirement sign-off, acceptance testing and evidence collection, then compare that with the supplier's own reporting.
Does a contract clause alone meet the A.8.30 control?
No. A contract clause sets the rules, but A.8.30 asks the organization to direct, monitor and review the outsourced work, so the clause must be backed by activity that actually happens. Auditors typically look for security requirements in the agreement, evidence that the supplier follows them, records of reviews and acceptance decisions, and a way to act when the supplier falls short. Related controls such as A.5.20 on information security within supplier agreements and A.8.29 on security testing in development and acceptance usually sit alongside it, so the contract and the testing evidence should be read together.
What does the work need from our own staff?
Your staff must keep ownership of the decisions even when a supplier writes the code. In practice this means a named owner for each outsourced system, someone who can read security requirements and judge whether delivered work meets them, and a reviewer for code and test results. These roles are the organization's responsibility and cannot be fully handed to the supplier or to an outside partner. Confirm early who has time for these reviews each sprint or release, because gaps in reviewer time are the most common reason outsourced work is accepted without adequate checks.
How long does preparation take, and what drives the timeline?
No general duration for A.8.30 preparation is set by the standard, so the timeline depends on the starting point. Teams that already have written supplier contracts, a repository with access records and an acceptance process usually need less time than teams that must create all three. The main drivers are the number of outsourced systems, whether security requirements already exist, how many suppliers hold access to code, and how quickly the supplier can provide its test and security evidence. Ask any consultant or partner for a written schedule tied to the agreed scope rather than a generic estimate.
Can we run A.8.30 in-house without an outside partner?
Often yes, if the organization has staff who understand both the contracts and the technical testing. The control itself is about oversight, so in-house teams can run it if they keep records and reviews consistently. Outside help is most useful for drafting security requirements, setting up repository and scanning evidence, and preparing material for the independent auditor. An implementation partner such as DeployOpen can prepare systems and evidence for an assessment, but it does not issue audit reports or certificates, and the organization still owns its controls. Compare the cost of an external engagement with the internal time that would otherwise go to building these routines.
What should we request in a written scope before engaging a partner?
A written scope should list the outsourced systems covered, the supplier roles and access involved, the security requirements to be defined, the review and acceptance steps to be set up, the evidence to be produced and the tools to be installed. It should also state what the organization keeps, such as decisions, sign-offs and supplier management, and what the partner delivers. Ask for deliverables by name, the assumptions behind the schedule and the fee basis, and confirm that the partner will not act as the independent auditor. DeployOpen works to fixed-scope agreements in writing before work starts, and quotes follow from that scope.
Which open-source tools can produce evidence for A.8.30?
Several self-hosted tools can generate evidence that supports A.8.30 reviews. GitLab Community Edition protected branches can restrict who pushes or merges to a branch and block direct pushes. Semgrep Community Edition can scan code in continuous pipelines. OWASP Dependency-Track consumes CycloneDX SBOMs and tracks vulnerable components and license risk, and Trivy can produce SBOMs and scan existing ones. Each tool produces records a reviewer can inspect, but none of them proves the supplier's process on its own. Confirm each tool's capabilities against your supplier's language and build setup before relying on it.
How DeployOpen prepares outsourced development evidence
DeployOpen helps organizations set up the technical side of outsourced development so that the evidence for A.8.30 exists before an auditor asks for it. We plan, implement and document the systems, repositories and checks that show how external developers are directed and reviewed. The organization keeps ownership of its supplier contracts and controls, and an independent auditor or certification body issues any report or certificate.
How we scope
- Engagements are fixed-scope, with the systems, supplier repositories and review points agreed in writing before work starts
- The written scope lists which outsourced development activities need monitoring, review and acceptance evidence
- Scope defines who in the organization owns supplier contract terms, which DeployOpen does not draft or negotiate
- Ask for the scope to name each evidence artifact to be produced and the party responsible for keeping it current
How we build
- We configure self-hosted source control so supplier access is limited, direct pushes are blocked and protected branches are enforced
- We set up security scanning of supplier code in the organization's pipelines, with rules agreed with the development owners
- We deploy software bill of materials and component tracking so supplier dependencies can be reviewed and their licenses checked
- We document the review gates that sit between supplier delivery and production, including who approves each release
How we hand over
- We deliver written procedures that describe how outsourced work is directed, monitored and accepted, as agreed in scope
- We provide configuration records, pipeline definitions and access listings that an assessor can sample during an audit
- We train the organization's staff to run the review gates, sign off acceptance tests and retain supplier evidence
- We agree in writing what evidence stays in the organization's own systems after handover
How we support
- Ongoing support, upgrades and continuous security testing are available as retainers after the initial engagement
- We can review the supplier evidence set periodically so records stay current with changes in suppliers and contracts
- Support covers keeping tooling upgraded and documentation aligned with the organization's own change process
- Confirm with us in writing which support tasks sit inside a retainer and which remain with the organization's own staff
