What CC5.1 asks a SOC 2 auditor to see in your control set
CC5.1 asks the organization to select and develop control activities that help reduce risks to its objectives to acceptable levels. In plain terms, every control in the SOC 2 matrix should exist because a specific risk calls for it, and the risks that matter to the service should each have a control that addresses them. Many control matrices look complete on paper because they list dozens of familiar controls, yet an auditor who asks why a given control exists often gets an answer that points to a template rather than to a risk. That gap is the problem CC5.1 targets: controls with no traceable reason, and risks with no control at all.
The difficulty is usually not in writing controls but in the link between the risk assessment and the control design. Teams often complete a risk register under CC3, write a control matrix under a separate effort, and never record how one informed the other. Auditors then have to reconstruct the logic from memory and interviews. Start by checking whether each high-priority risk in your register maps to at least one control, and whether each control names the risk it reduces. Confirm with your auditor how they expect that traceability to be shown, since the form of the record is their call as well as yours.
The points of focus for CC5.1 are useful prompts for that review rather than a checklist to pass. They cover whether controls are integrated with the risk assessment, whether they reflect the organization's own circumstances and business processes, whether the mix of preventive, detective and corrective activities fits the risks, whether controls operate at the right level of the process, and whether duties that could enable fraud or error are separated. Reviewing your matrix against these themes, and recording the decisions you made, gives an assessor the reasoning behind the control set. The AICPA 2017 Trust Services Criteria contain the full wording of the points of focus, and your auditor will test against that text.
Which risks, systems, teams and vendors CC5.1 covers in practice
Scope decides which control activities CC5.1 needs to address, so the choices below set the size of the work before any control is written. Each choice depends on the system description and the categories included in the examination, which together define the boundary the auditor tests.
The risk register and its scope
CC5.1 expects control activities to reduce risks to acceptable levels, so the risk assessment under CC3 is the starting list. Decide which risks sit inside the examination, such as unauthorized access to customer data or failed deployments, and which are handled elsewhere. Check that every risk you accept or exclude has a recorded owner and a stated reason, because an auditor will ask how each control traces back to a named risk.
In-scope systems and data
List the production applications, databases, cloud accounts, backup stores, logging pipelines and build systems that handle the data covered by your commitments. A self-hosted platform deployed in a client's cloud or data center may be in scope in one environment and out of scope in another, so confirm the boundary with the client and the auditor before controls are designed. Each in-scope system needs an owner and at least one control that applies to it.
Business processes that rely on technology
Map the processes whose outputs depend on software, such as customer onboarding, billing, payroll exports, support ticket handling and data deletion requests. CC5.1 points to relevant business processes as a source of control activities, because a control placed on an unmapped process tends to miss the step where errors actually occur. Walk each process end to end and mark the points where a person approves, a system computes, or data moves between tools.
Entity-specific commitments and factors
Customer contracts, data processing agreements, security questionnaires and regulatory obligations often set requirements beyond the generic criteria. Record which commitments you have made, such as encryption at a stated standard or retention periods, and which industry rules apply to your customers. These factors determine which control activities are required and how strict they must be, so review them with legal and sales before the control set is finalized.
Third parties whose controls you rely on
Identify cloud providers, hosting partners, managed service providers and software vendors whose controls support your own. Decide whether you rely on their SOC reports, carve their controls out of your system description, or perform your own monitoring. Each reliance needs a documented basis, such as a current report reviewed for exceptions and complementary user entity controls assigned to your team, because the auditor will test how you used that report.
Level at which controls operate
Decide whether each control operates at the organization, team, system or process level. An access review run once for the whole company covers different risk than one run per production system, and the choice affects how many instances the auditor samples and how much evidence you collect. Choose the level that matches the risk, and avoid setting a control so broadly that no one can show it operated for every in-scope system.
How an assessor tests control selection and design
This table sets out how a service auditor typically tests whether control activities were selected and designed to reduce risk, what evidence they ask for, and where engagements most often stall. Read each row as a test the organization should rehearse before fieldwork, not as a checklist the auditor is bound to follow.
| Test approach | Evidence requested | Common findings |
|---|---|---|
| Trace a sample of risks from the risk assessment to mapped controls | Risk register with owners and ratings, control matrix showing which controls address each risk, and the date each mapping was last reviewed | Controls with no mapped risk, or risks with no control and no documented acceptance decision |
| Check that control types are mixed (preventive, detective, corrective, manual and automated) | Control matrix tagged by type and nature, plus examples of a detective review and a corrective action record for a past exception | A matrix dominated by one type, such as policy statements with no detective or corrective component |
| Test whether controls operate at the level where the risk arises | System or process diagrams, scope boundaries, and samples showing the control applied at the account, service, environment or business unit where the risk sits | A control applied at a summary level (for example, a quarterly headline review) while the risk originates in individual production systems |
| Review segregation-of-duties conflicts in key processes | Access matrix or role design for key processes such as code deployment, payments and user provisioning, with conflict analysis and any approved exceptions | Conflicting duties held by one person with no compensating control or documented approval |
| Check whether the control matrix is reviewed when risks change | Change log for the risk register and control matrix, meeting minutes or sign-offs after material system, vendor or organizational changes | Matrix unchanged after a new product, hosting provider or major team change, with no record of a reassessment |
| Confirm controls are described precisely enough to be tested | Control descriptions stating who performs the activity, how often, what triggers it and what evidence it produces | Vague descriptions such as reviews security regularly, which an auditor cannot sample or re-perform |
How to build a control set that traces back to risk
This sequence turns the risk assessment and the company's objectives into a control matrix in which every control has a stated risk, a type, an owner and an approval. An assessor can then follow each line from risk to control to evidence without guessing why the control exists.
Confirm the risk assessment and service objectives
Start by checking that the risk assessment under CC3 is current and that the service commitments and system requirements it was built on still match how the product runs. Leadership and the people who own the system should agree on the objectives, and any change since the last assessment should be recorded. The output is a short, dated statement of objectives and the risk assessment version that the control set will be built against. You know this step is complete when every later decision can point to that version.
List risks by in-scope system and process
Break the risk assessment into the in-scope systems, such as production infrastructure, the deployment pipeline, the identity provider and customer support tooling, and the business processes that touch them, such as onboarding, access changes and vendor management. For each system and process, list the risks that could stop the company from meeting its objectives, with the entity-specific factors that raise or lower them. The output is a risk register organized by system and process, with each risk given a unique reference. Confirm with the risk owners that nothing in scope is missing.
Select a mix of control types for each risk
For each risk, decide which combination of control types will bring it to an acceptable level. A mix usually includes preventive controls that stop a failure, detective controls that find one, and corrective controls that repair it, and it may include manual and automated controls side by side. Record the reason for each choice so the assessor can see why one design was preferred. The output is a risk-to-control map in which every risk has at least one control, and the residual risk that remains after the control is recorded in the same row.
Assign owners and the level of operation
Give every control a named owner who is accountable for performing or overseeing it, and state the level at which it operates, such as the whole company, a business unit, a system, or a specific account or transaction. Controls that run at a broad level can cover several risks, while narrow controls need a more precise description of what they check. The output is an updated matrix with owner, level and frequency for each control. Confirm with each owner that they accept the role, because an assessor will ask them to explain the control.
Map segregation of duties and compensating controls
Review the access and responsibility assignments for each process and identify conflicts, such as one person who can both request and approve a production change or who can both create and pay a vendor. Where a conflict cannot be removed for a small team, document a compensating control, such as an independent review of the activity, and record who performs it and how often. The output is a segregation-of-duties map with each conflict, its resolution or compensating control, and its owner. Check that the compensating control is itself a control with evidence.
Approve the control matrix and retain it
Gather the risk register, the risk-to-control map, the ownership entries and the segregation-of-duties map into one control matrix and have management approve it. Approval should be recorded with a date and the names of the approvers, and the matrix should be stored under version control so later changes are visible. The output is an approved control matrix that the auditor can use as the starting point for testing. Changes to the matrix should go back through the same review, and a preparer should confirm with the independent auditor whether the level of detail meets their expectations before fieldwork begins.
Why acceptable risk is a judgment you must document
CC5.1 does not ask you to eliminate every risk to your service commitments. It asks you to select and develop control activities that reduce risks to acceptable levels, and the word that carries the weight is *acceptable*. Management decides where that line sits, and the decision belongs to people who own the objectives, not to the auditor or the tooling. The practical test is whether you can show, for each material risk identified in CC3, which controls reduce it, how far they reduce it, and why whatever remains is a risk the organization has chosen to carry. A residual risk with no recorded rationale is the gap an assessor is most likely to find, because it looks like a risk nobody considered.
Those records matter in two stages. In a Type 1 examination, the auditor evaluates whether the controls, as designed, could reduce the identified risks to the level management stated, as of a specific date. In a Type 2 examination, the auditor then tests whether those same controls operated across the observation period. If the design rests on an unexplained assumption, such as a risk being low because a vendor is trusted, the operating test will not repair it. Treat the risk register, the control matrix and the accepted-risk entries as one linked set. Confirm with your auditor how they expect the accepted-risk entries to be dated, approved and reviewed, since the expectation is set by the engagement and the report period, not by a fixed template.
The reasoning is what gets tested, so write it down in plain terms: the risk, the objective it threatens, the controls relied on, the residual exposure, the approver and the review trigger, such as a change in the system, a new subservice organization or a related incident. The COSO principle that CC5.1 restates and the 2017 Trust Services Criteria both expect controls to be selected in proportion to the risks they address, and an auditor will ask whether that proportion is reasonable for your environment. Before fieldwork, ask yourself whether someone outside the team could follow the path from each accepted risk to a named owner and a dated decision. If the answer is no, the control design is not finished, however many controls appear in the matrix.
Evidence that shows controls were selected from risk
An auditor testing CC5.1 looks for a traceable chain: risks identified, controls chosen against those risks, and approvals and reviews that show the set stayed current. Each item below is one link in that chain, and each needs an owner and a refresh rhythm between audit periods.
Risk register and assessment
The risk assessment is the starting point for CC5.1. It lists the risks to service commitments, how each was rated for likelihood and impact, and the risk owner. Check that every risk carries a rating and a treatment decision (accept, reduce, transfer or avoid), and that new systems, vendors and product changes added since the last assessment appear in it. Review the register at least annually and after material changes, and record the date and approver of each version.
Control matrix with risk mappings
The control matrix links each control activity to the risk or risks it reduces, the control type (preventive, detective or corrective, manual or automated), the owner and the frequency. An auditor uses it to trace a risk to a control and then to the evidence for that control. Confirm that no high-rated risk lacks a mapped control and that no control is orphaned from a risk. Update the matrix whenever a control is added, retired or changed.
Segregation-of-duties matrix
This matrix shows which combinations of duties must not sit with one person, such as requesting and approving production access, or writing and deploying code. Where a small team cannot separate a duty, the matrix records the compensating control, such as an independent review of logs or a second approver, and the reason the gap exists. Review it when roles change, when a new environment is added and at each access review, because role drift is the most common way separation erodes.
Approval records for the control set
Management should approve the risk assessment, the control matrix and any exceptions in writing, with a version number and date. The approval shows that someone accountable accepted the residual risk and the control design. Keep signed or system-recorded approvals and the change history between versions. Ask your auditor which level of management they expect to approve, because the answer shapes who must sign off.
Review evidence after material changes
When a material change occurs, such as a new hosting region, a new subservice organization, an acquisition or a significant incident, the risk assessment and control matrix should be reviewed and the result recorded. This review shows that the control set responds to the business rather than sitting unchanged for a year. Keep a dated change log that links each change to the review ticket, the updated risks and any new or retired controls.
Operating evidence for key controls
Selection is only credible if the key controls operate. For each high-priority control, keep samples that show it ran as designed, such as a completed access review, a recorded approval or an alert that was triaged. Confirm the sample population is complete and that each record shows who performed the control and when. Collect this evidence on a fixed schedule throughout the period, not only before fieldwork, so gaps surface while they can still be fixed.
Who owns control selection and who can help
Your organization owns its control activities, and the people who own the risks must own the choices about them. Management decides which risks from the risk assessment are acceptable, which controls reduce each risk to an acceptable level, and who is accountable for each control operating over time. Those decisions cannot be delegated to a consultant or to the auditor, because the SOC 2 report describes controls that management has committed to run.
- Owning risks: Name an owner for each risk in the register, usually the executive accountable for the system or business process it touches.
- Approving the matrix: Leadership signs off on the control matrix, including which control types and levels were chosen and why.
- Accepting residual risk: Record which risks remain after controls are applied and who accepted them, in writing.
- Segregating duties: Decide who may request, approve and perform a change or access grant, and confirm no single person can do all three.
- Funding and staffing: Assign the people who will perform recurring control activities after the examination starts.
Before the examination, confirm that each named owner can explain the control in their own words and point to the evidence it produces.
An implementation partner helps your team prepare systems, controls and evidence. It does not decide which risks you accept, and it does not issue a SOC 2 report, attestation or opinion. Only an independent CPA firm can issue those. A partner's work is preparatory and should be documented so your team can run the controls without it.
- Risk-to-control map: Draft a traceable link from each risk in your assessment to the control activities intended to reduce it, for management review.
- Matrix drafting: Write the control matrix entries, including control owner, frequency, evidence source and the criterion each control supports.
- Tooling configuration: Configure self-hosted systems, such as ticketing, logging and access review tools, so they produce the evidence the controls need.
- Documentation: Prepare procedures and runbooks that describe how each control is performed, reviewed and retained.
- Handover: Train your staff to operate the controls and produce evidence without ongoing outside help.
Ask any partner to state in writing which parts of the work it will perform and which remain with your organization.
The independent CPA firm tests whether your controls are designed suitably and, for a Type 2 report, whether they operated effectively over the period. The auditor's independence is a requirement of the engagement, and it limits what the auditor can build for you. If the auditor designs your controls, its later testing of those same controls is compromised, and the report loses its value to customers.
- Design testing: The auditor evaluates whether each control, as designed, could reduce the related risk to an acceptable level.
- Operating effectiveness testing: For Type 2, the auditor samples evidence across the observation period to confirm controls ran as described.
- Management representations: The auditor relies on written representations from management about the system and its controls.
- Exceptions: Any control failure is reported as an exception, whatever the cause.
- Boundaries: Ask the auditor which preparatory help it can provide without affecting independence, and get that answer in its engagement letter.
Check that the auditor and any consultant have separate responsibilities written into their contracts before work starts.
What selecting and documenting controls costs
What internal costs come with selecting control activities for SOC 2?
The largest early cost is internal time, not software. Selecting control activities means running risk workshops in which engineering, operations, HR, finance and product leaders agree which risks from the CC3 risk assessment matter and which controls reduce them to acceptable levels. Each participant gives up hours, and someone must prepare the risk register, draft the control matrix and chase owners for sign-off. This work is one-time for the initial design but recurs whenever the system, the vendor set or the customer commitments change. Costs rise with the number of systems in scope, the number of teams that own a risk, and how often the organization reopens decisions it already made. Ask any outside party to show how it will reduce that workshop load, and confirm who on your side must attend each session.
Do self-hosted open-source tools reduce the licensing cost of a control matrix?
They can remove the recurring license line for a governance, risk and compliance platform, but they do not remove the cost of running it. A self-hosted tool such as CISO Assistant, which is licensed under AGPL-3.0-only and ships framework libraries including SOC 2, still needs hosting in your own cloud account or data center, a database, backups, access control, upgrades and an owner who keeps the control matrix accurate. Those are real operating costs, and they recur. Commercial GRC tools may bundle evidence collection and integrations that save engineering time, so compare the total effort, not only the subscription price. Confirm the license terms with the vendor and ask your auditor whether they accept the evidence exports the tool produces.
How much engineering time does implementing a control activity take?
Engineering time depends on whether a control already exists in the platform. Many control activities, such as enforcing multi-factor authentication, restricting production access or requiring peer review before deployment, need configuration of identity providers, pipelines and infrastructure as code. Others, such as automated alerting on configuration drift, need new monitoring rules and tested runbooks. One-time build work is usually the biggest engineering cost. Recurring work includes maintaining those configurations as the platform changes and reviewing alerts. Costs go down when controls are defined as code and reused across environments, and up when each team builds its own version. Ask for a list of each control, the system it touches, and the engineer responsible before accepting any estimate.
What recurring evidence upkeep should we budget for after the first control design?
Evidence upkeep is the cost that most often surprises teams after a first readiness effort. For each control, someone must collect evidence on a schedule, such as access review exports, change tickets, vulnerability scan results, training completion records and joiner and leaver records. Each record must be complete, dated and traceable to the control it supports. Recurring costs include the time of control owners, the time of whoever reviews the evidence, and the time spent answering auditor requests. The volume grows with the number of controls, the number of systems and the frequency of each activity. Automating collection from the source system lowers the recurring cost, but automation must itself be tested and documented. Ask your provider to specify which evidence is automated, which is manual, and who owns each recurring task.
Is an external readiness review worth paying for before the auditor arrives?
A readiness review is optional, but it is a one-time cost that can reveal gaps in control design before the auditor tests them. An independent consultant can compare your control matrix against the 2017 Trust Services Criteria, check that each control is tied to a risk, and identify missing owners or weak evidence. The review does not produce a report or certificate. Only an independent CPA firm issues a SOC 2 report. Its cost depends on the number of criteria in scope, the number of systems, and how much documentation already exists. Ask whether the review is fixed-scope, what deliverables it produces, and whether the same firm will then support the preparation work. DeployOpen plans and implements control activities within the client's own infrastructure and prepares evidence for assessment, on fixed scope agreed in writing before work starts.
How does auditor sampling effort affect what we pay for SOC 2 controls?
The auditor tests a sample of each control over the examination period, and the effort depends on how many items the auditor must inspect and how easily you can produce them. For a Type 2 report, sampling covers an observation period rather than a single date, so the auditor needs evidence across that whole period. Controls with clear, timestamped records, such as tickets linked to approvals, are faster to test than controls that depend on memory or email threads. Weak design, unclear ownership and inconsistent records increase the number of follow-up requests and the time billed. Costs can be reduced by defining precise control descriptions, standardizing evidence locations and running a dry run before fieldwork. Ask the auditor how it will select samples, how many items it expects per control, and how it prefers evidence to be delivered.
Which parts of control selection should we do ourselves and which should we outsource?
Your organization owns its controls, so decisions about risk tolerance and which controls are acceptable must stay in-house. Staff who understand the business should run the risk workshops, approve the control matrix and accept residual risk. Outside help is most useful for drafting control descriptions in the auditor's terms, building technical controls on self-hosted platforms, testing that the controls work, and preparing evidence. Keeping decision rights internal and buying implementation capacity externally usually keeps the cost predictable. Before you sign anything, ask for a written scope that lists each control, each deliverable, who approves each decision and what happens if the scope changes.
Open-source tooling that maps risks to controls
This table compares the parts of a CC5.1 control map that tooling can hold, and what the organization still has to decide itself. Read it as a checklist of what to configure and what to confirm before adopting a tool for the risk-to-control link. The main takeaway is that a tool can store and link the mapping, but the risk judgments and control choices remain the organization's.
| Mapping element | What the tool can hold | What the organization still decides |
|---|---|---|
| Risk register entries | Risks recorded with owners, likelihood and impact fields, linked to the objectives they affect | Which risks apply to the system, how they are scored, and what risk tolerance is acceptable |
| Control catalog | Controls defined once and reused across frameworks, including SOC 2 criteria such as CC5.1 | Whether each control is actually designed and operating in the environment, and at what level it applies |
| Risk-to-control links | Each risk linked to one or more controls, showing which risks rely on which controls | Whether the mix of preventive, detective and corrective controls is adequate for each risk |
| Framework mapping | Automatic mapping between frameworks, such as SOC 2 and ISO 27001, where supplied by the tool | Whether the automatic mapping matches the organization's own interpretation; confirm each mapping before relying on it |
| Assessment records | Assessments run against selected frameworks with status and evidence attached | Who reviews assessment results and which exceptions are accepted or remediated |
| Segregation of duties | Recording of role owners and approvers for each control | Whether role assignments actually separate conflicting duties in the systems that run the controls |
| Licensing and fit | AGPL-3.0-only license, with more than 200 frameworks supplied | Confirm with counsel what AGPL-3.0-only obligations apply to the planned deployment and any modifications |
Where control selection usually breaks down
Most CC5.1 findings do not come from missing controls. They come from controls that were chosen without a clear link to the organization's risks, its systems or its people. The six patterns below are the ones assessors and remediation teams see most often, each with the check that closes it.
Controls copied from a template
A control set downloaded from a framework or a previous employer often lists controls the organization never needed and omits risks it actually carries. CC5.1 expects control activities selected to reduce risks to acceptable levels, so each control should trace back to a specific risk the organization identified. Check that every control in the matrix names the risk it addresses. Remove or rewrite any control that cannot name one.
Risk assessment that never reaches controls
The risk register is often written once, filed, and never connected to the control matrix. CC5.1 points to integration with the risk assessment, which means high-rated risks should have visible controls, owners and testing. Ask whether each risk rated high or critical maps to at least one control, and whether any risk accepted by management has a documented reason for accepting it.
One control type for every risk
Teams often rely only on policies and periodic reviews, or only on automated technical blocks, regardless of the risk. CC5.1 points to a mix of control activity types, including preventive, detective and corrective controls, and manual and automated ones. Check each high-risk area for at least one preventive and one detective control, so a failure in one still leaves a second line of defense.
Controls at the wrong level
A team lead reviewing their own group's access may satisfy a local need but not a risk that spans the whole organization, such as customer data exposure across products. CC5.1 asks whether activities operate at the level where the risk arises. Check which controls cover organization-wide risks, and whether a reviewer above the affected team actually performs or signs off on them.
Unresolved segregation-of-duties conflicts
A single engineer who can write code, approve the change and deploy it to production holds a conflict that no policy text fixes. CC5.1 addresses segregation of duties as a point of focus, so the design should separate conflicting roles or add compensating review. List every person with production access alongside the change approval rights they also hold, then either split those rights or document a compensating control with a named reviewer.
No review when systems or vendors change
Controls designed for last year's architecture can silently stop working after a new cloud region, a new SaaS vendor or a migrated database. Because CC5.1 selections must stay tied to current risks, a change in systems or third parties should trigger a reassessment of the relevant controls. Confirm that the change process includes a step that asks whether the control set still fits the new environment, and record the outcome.
Questions buyers ask about CC5.1 cost, effort and readiness
How much effort does CC5.1 take for a small SaaS company?
The effort depends on how many risks the risk assessment (CC3) produces and how many of them need a control that is not already running. CC5.1 itself asks for a documented link from each significant risk to the controls that reduce it, so a small company with a short risk register and a few existing controls has far less to design than one that has never written its risks down. The main internal work is an owner who understands the systems, time for a few working sessions to map controls to risks, and someone to keep the mapping current as the product changes. Ask any consultant to break their quote into design work, evidence collection and auditor support, because the internal share often decides the total.
Can an auditor design the control set for us?
No. The organization owns its controls and decides which ones reduce its risks to acceptable levels. An independent CPA firm examines the design and tests operating effectiveness, but it does not issue the controls it then audits, because that would compromise its independence. Some CPA firms offer readiness assessments that point out gaps, and that is a different engagement from the examination. Consultants and implementation partners can help draft the control matrix and prepare the evidence, while the company keeps accountability for the result. Confirm the boundary in the auditor's engagement letter before work starts.
What does the team have to supply for CC5.1?
The team supplies the facts that the control set is built on. Typical inputs include:
- A current risk assessment with identified risks, owners and ratings
- A system description with its infrastructure, data flows, vendors and business processes
- Named owners for each control, with the authority to act on it
- Access to the systems that produce evidence, such as identity, cloud and ticketing tools
- Decisions on acceptable risk levels and on which control types suit each risk
Most delays come from missing owners and an outdated system description, not from the mapping exercise itself.
How long does CC5.1 readiness usually take?
The supplied research does not give a typical duration for CC5.1 readiness, so treat any number from a vendor with caution. Timing depends on the maturity of the risk assessment, how many controls must be added, whether systems already produce evidence, and how quickly owners can make decisions. Ask the implementation partner or consultant to state the assumptions behind their schedule, the work that depends on your team, and which milestones are fixed in the written scope. Confirm with your CPA firm which period it expects the examination to cover, since that sets how much time evidence must be collected.
Does the CC5.1 control matrix need a GRC tool?
No. A SOC 2 does not require a particular tool, and a well-kept spreadsheet or document can hold the mapping from risks to controls, owners and evidence. A GRC platform becomes useful when the number of risks, controls and recurring evidence requests grows, or when several teams need to review the same records. Open-source options exist, including CISO Assistant, which is licensed under AGPL-3.0-only and ships more than 200 frameworks, including SOC 2. Whatever you choose, confirm with your auditor that the matrix format, versioning and evidence links are acceptable before the examination period begins.
How does CC5.1 differ from CC5.2 and CC5.3?
CC5.1 covers how the organization chooses and designs control activities against its risks. CC5.2 covers the general controls over technology that support those activities, such as infrastructure, security management and technology acquisition, development and maintenance. CC5.3 covers how those activities are deployed through policies that set expectations and procedures that carry them out, including ownership, timely performance and periodic reassessment. In practice, CC5.1 produces the control matrix, CC5.2 supplies the technology controls that many entries depend on, and CC5.3 provides the policies and procedures that make each control operate on schedule.
How DeployOpen prepares control selection for an audit
DeployOpen plans, implements and documents the control activities behind a CC5.1 decision inside your own infrastructure, under a fixed-scope written agreement. In practice that means working from your risk assessment to pick the control activities for each in-scope criterion, deciding where each one operates (for example, at the system level, the process level or the transaction level), confirming that the mix includes preventive, detective and manual or automated controls, and laying out who performs and who reviews each control so that no single person can initiate, approve and record the same change. The output is a control matrix, the configured systems behind it, and the evidence each control will produce, delivered in a form your team can maintain after the engagement ends.
DeployOpen prepares systems, controls and evidence. It does not issue SOC 2 reports, opinions or attestations. The examination is performed by an independent CPA firm, which makes its own judgments about whether the controls you designed are suitable and whether they operated effectively over the period it tests. Your organization owns the control environment, the risk decisions and management's written description of the system. Before you commit to a scope, ask the CPA firm you intend to use to review the draft control matrix so that any gap in selection or segregation of duties is found before fieldwork rather than during it.
To move from this topic to a concrete plan, send us your current risk assessment, your list of in-scope systems and any existing policies, and we will return a written scope with deliverables and timelines for you to approve before work starts. Quotes follow from that written scope, and DeployOpen does not publish a price list. Ask every provider, including us, to state in writing what they will deliver, what you must provide, and which parts of the examination remain with your auditor.
