What does CIS Controls implementation cost for your organization?
There is no fixed price for implementing the CIS Controls, but the cost benchmark most buyers should start with is CIS's own estimate: obtaining and deploying commercially supported tools for Implementation Group 1 should cost less than 20% of the IT budget for any size enterprise. CIS reached that figure in *The Cost of Cyber Defense: CIS Controls IG1*, which groups the IG1 Safeguards into categories, identifies the tool types needed and prices them from researched commercial license costs. CIS also notes that the 56 IG1 Safeguards do not require 56 tools, because one enterprise and software asset inventory tool can address several Safeguards at once. Treat the 20% figure as an upper-bound planning anchor for tooling, not a quote for your environment. The Cost of Cyber Defense guide sets out the categories and the method behind it.
The real total depends on four variables: which Implementation Group you target (IG1 covers 56 Safeguards, IG2 adds 74 and IG3 adds 23), what tools you already own, how many people and assets you run, and whether you buy outside help. Licensing is usually priced by employees, users, workstations, servers or usage, so headcount and asset counts move the tooling line. Staff time, policy writing, evidence collection and internal assessment are the larger recurring costs and are often absorbed internally. Ask any implementation partner for a written scope that lists the Safeguards covered, the tools assumed (with license counts and terms), who performs each task and what is one-time versus annual. Confirm whether a quote includes tooling licenses or only services.
Two points are often confused in budget discussions. First, the Controls are free to use: CIS publishes them under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 license, and commercial use requires CIS's prior approval. Second, no organization is certified against the CIS Controls, so a budget for a certificate is a budget for something that does not exist. The only published CIS fees relate to CIS SecureSuite membership, which is priced by employee count and is not required to implement the Controls. Free membership applies to US state, local, tribal and territorial government entities and US public academic institutions. Confirm with CIS whether any membership or tool you consider fits your use before you commit budget.
Who gets paid for what, and what recurs
This table lists each cost component of a CIS Controls program, who receives the money or effort, whether it is one-time or recurring, and what drives its size. Read it as a checklist for a quote: every row should appear in the written scope or be ruled out explicitly. The main takeaway is that tool licences and staff operation recur every year, while build work and partner fees are usually concentrated at the start.
| Cost component | Who is paid or who spends effort | One-time or recurring | What drives the size |
|---|---|---|---|
| Commercial tool licences | Software vendors, paid by the organization | Recurring, usually annual | Priced per employee, user, workstation, server or usage, as CIS's IG1 Enterprise Profiles model; one tool can cover several Safeguards |
| SecureSuite End User membership | Center for Internet Security, paid by the organization | Recurring, annual (discounts for 2- and 3-year terms) | Employee count band; free for US SLTT entities and US public academic institutions; does not permit client or commercial use |
| Internal staff time | The organization's own IT, security and compliance staff | Largely one-time build, then recurring operation | Asset estate size, number of Safeguards in scope, current maturity, and how many tools must be integrated |
| Implementation partner fees | External implementation partner, paid under a written fixed-scope agreement | One-time for the agreed scope, plus optional recurring retainer | Scope agreed in writing, number of environments, integrations and documentation deliverables; retainers cover upgrades and ongoing support |
| Independent assessment fees | Independent assessor or auditor, if a third party reviews evidence | Recurring when the review is repeated each cycle | Whether a third party reviews evidence, the depth of sampling, and how often the review repeats |
| CSAT Pro tracking (Controls-only membership) | Center for Internet Security, paid by consultants, MSPs and MSSPs | Recurring, 3,600 US dollars a year per CIS SecureSuite Controls Membership | Applies only to the Controls-only membership aimed at consultants, MSPs and MSSPs tracking customer implementations |
What moves the CIS Controls cost up or down
Most of the cost of implementing the CIS Controls comes from a few decisions: which Implementation Group you target, how many people and tools you carry, and how much of what you need you already own. The cards below cover the levers you can set and the checks to run before you request a quote.
Implementation Group target
IG1 contains 56 Safeguards, IG2 adds 74 and IG3 adds the remaining 23. Each step up brings more tool categories, more processes to document and more assessment work, so the target group sets the size of the scope before any tool is priced. Ask for the quote to list which Safeguards are in scope by group, and confirm whether a first phase stops at IG1 with later phases priced separately.
Headcount and membership band
Headcount affects two costs. Many commercial tools are priced per employee, user, workstation or server, so a larger population raises license fees. CIS SecureSuite End User membership is also banded by employee count, so the same headcount sets the membership fee. Confirm the headcount basis your tool vendors use, count it once, and reuse the same figure in every quote.
Tool consolidation
The 56 IG1 Safeguards do not require 56 tools. CIS notes that one enterprise and software asset inventory tool can address Safeguards 1.1, 1.2, 2.1, 2.2, 2.3, 9.1 and 12.1. Ask each vendor or partner which Safeguards a product covers, and reject overlapping purchases that add licenses without adding coverage. Consolidation is usually the largest lever on recurring license spend.
Existing tooling and licenses
Tools you already own reduce the new spend, but only if they are configured for the Safeguards they support and their license terms cover the scope. Inventory current endpoint protection, identity, logging and backup products, then map each to the Safeguards it addresses. Check renewal dates and whether licenses are priced by the same unit you plan to use, since a mismatch can make an existing license insufficient.
Locations, cloud accounts and third parties
Each additional site, cloud account, subscription or third party that holds in-scope data adds assets to inventory, logs to collect, configurations to baseline and contracts to review under Control 15. These items drive labor and tool capacity more than headcount does. Before quoting, list every location, cloud account and service provider in scope, and ask whether the quote assumes a fixed count or a per-unit rate.
Evidence maturity
Teams with current asset inventories, written processes and recorded configuration baselines spend less on assessment and remediation. Teams that must reconstruct these records first pay for that rework, usually through extra partner hours and delayed tool deployment. Before requesting a quote, check whether your policies, process documents and inventory exports exist and are current, and state the gaps in the scope so the estimate reflects them.
How the cost differs for a small business, a public body and a service provider
A private enterprise pays for the Controls in three places: the tools that produce the evidence, the staff time to configure and run them, and any outside help. CIS's own estimate for IG1 is that commercially supported tools should cost less than 20% of the IT budget for any size enterprise, and CIS researched commercial license prices across 10 tool categories to reach that figure. Tool prices are commonly set per employee, user, workstation, server or usage, so the bill grows with the estate.
- Tools: Recurring licenses for categories such as asset inventory, endpoint protection, backup and logging. CIS notes that one tool can address several Safeguards, so the count of tools is usually lower than the count of Safeguards.
- Staff time: Internal effort to write processes, configure tools and collect evidence. This is often the largest one-time cost for a small team.
- Open-source alternatives: Self-hosted platforms can replace some commercial licenses, but they still need installation, hardening and upkeep.
- Outside help: Fixed-scope implementation or readiness work, quoted from a written scope.
- Budgeting aid: CIS publishes a downloadable budgeting spreadsheet with its Cost of Cyber Defense guide.
Before relying on any figure, confirm the tool prices, licensing model and headcount with your own vendors and environment.
US state, local, tribal and territorial (SLTT) government entities and US public academic institutions can use CIS SecureSuite membership at no charge. That removes the membership fee, but it does not remove the cost of the tools, staff and services needed to implement the Controls. The Cost of Cyber Defense estimate still applies to the tooling side, so public bodies should budget for licenses and people even when the membership line is zero.
- Membership: Free for qualifying SLTT entities and public academic institutions, according to CIS's End User pricing page.
- Tools: Still paid for, and CIS's IG1 tool categories still apply.
- Staff time: Often the main cost in public bodies with small IT teams.
- Shared services: Some public bodies share tooling or staff across agencies, which can change how licenses are priced. Ask the vendor about public-sector terms.
- Eligibility: Confirm with CIS that your organization qualifies before assuming the free rate.
Confirm your eligibility status and any public-sector license terms directly with CIS and your vendors before you finalize the budget.
A consultant or managed service provider that delivers the Controls to clients has a different cost structure. The SecureSuite Controls Membership, aimed at consultants, MSPs and MSSPs, costs 3,600 US dollars a year and includes CIS CSAT Pro for tracking customers' implementation of the CIS Controls. End User membership does not permit client or commercial use, so a provider working for clients needs the Controls membership rather than the End User tier.
- Controls membership: 3,600 US dollars a year, according to CIS's Controls Membership page.
- CREST-backed accreditation: CIS lists an application fee of 1,500 US dollars for CREST members and 2,500 for non-members. Accreditation applies to SecureSuite members that provide CIS Controls implementation, auditing or assessment services.
- Client tooling: Tools deployed for clients are usually priced per client or per asset, so the provider must recover them in its service fees.
- Staff certification and training: Ongoing costs for the people delivering the work.
- Recurring renewals: Membership and tool costs recur, so price them into each client engagement.
Confirm the current membership terms, accreditation fees and any renewal conditions with CIS before you price a client offer.
How to build your own CIS Controls budget from the IG1 estimate
This sequence turns CIS's published IG1 cost estimate into a line-item budget built from your own inventory, your own vendor quotes and your own staffing plan. The end result is a written budget you can defend to finance and test against outside quotes.
Download the Cost of Cyber Defense guide and spreadsheet
Start with CIS's white paper, The Cost of Cyber Defense: CIS Controls IG1, and its downloadable budgeting spreadsheet. The guide groups the 56 IG1 Safeguards into logical categories, identifies the tool types needed and sets out CIS's cost estimates, including an appendix that breaks cost down per tool. Read the methodology section first so you understand the assumptions behind the figures. The step is done when the security lead and finance owner have both read the methodology and agree which of CIS's assumptions match your environment and which do not.
Map current tools to the 10 categories
Inventory every security and IT tool you already license or run, then assign each one to the 10 tool categories CIS used in its estimate. Record the vendor, product, license basis and renewal date beside each entry. Many tools will cover several Safeguards, and CIS notes that one asset and software inventory tool can address several IG1 Safeguards, so map each tool to the Safeguard numbers it supports. The output is a tool register with a category and Safeguard coverage column for each entry, reviewed by the platform owner who can confirm what each tool actually does in production.
Map each IG1 Safeguard to a tool or process
Walk all 56 IG1 Safeguards and mark each one as covered by an existing tool, covered by an existing process, partly covered or not covered. A Safeguard that depends on a written policy or a documented process still needs staff time even when a tool exists, so mark those separately. Use the Safeguard descriptions in CIS's Controls v8.1 materials as the reference wording. The check is complete when every one of the 56 Safeguards has a status and an owner, and the uncovered or partly covered items form a gap list that drives the next step.
Price the gaps from current vendor quotes
For each gap, request written quotes from vendors or resellers and state your scope precisely: the employee count, workstation count, server count, user count or usage volume that the license is priced on. CIS notes that tools are commonly priced by employees, users, workstations or servers, or by usage, so the same product can cost very different amounts depending on how you count. Ask for one-time costs such as deployment and integration separately from recurring license and support fees. Compare the total against CIS's per-tool figures in the appendix. The output is a priced gap list where each line shows the quote, its basis and its renewal term.
Add SecureSuite membership if it applies
Decide whether a CIS SecureSuite membership is part of your plan. The End User membership fee is set by employee count, and CIS applies discounts for 2-year and 3-year terms. Confirm the current figures on CIS's pricing page because they are subject to change. End User membership does not allow client or commercial use, so a service provider needs a different category. US state, local, tribal and territorial government entities and US public academic institutions may qualify for no-cost membership. Add the fee as a recurring line item, or record it as zero with the eligibility reason written next to it.
Add internal staff time and partner scope
Estimate the internal effort for policy writing, asset ownership, access reviews, log review, incident exercises and Safeguard evidence collection, and assign each task to a named role. Then decide which parts you will buy from a partner, such as platform implementation, hardening, integration or testing, and write each one as a fixed scope with deliverables. Ask any partner to state which work produces configuration and evidence and which work an independent assessor must perform. The output is a staffing table and a scope document for each external engagement, both reviewed by the security lead and procurement.
Assemble and test the budget against quotes
Combine the tool lines, membership fee, staff time and partner scopes into one budget, separating one-time costs from recurring costs for each year. Label CIS's published figures as estimates and show which lines came from your own quotes. Then test the budget: compare CIS's per-category estimates with your quotes, explain every large difference in writing, and ask a second vendor or partner to review the scope and price. The step is done when finance signs off on a budget with a written basis for every line, and the difference from CIS's estimate is documented.
Frequently asked questions about CIS Controls cost
Is there a fee to use the CIS Controls?
No. CIS says the Controls are free for any organization to use to improve its own cybersecurity. The content is licensed under Creative Commons Attribution-NonCommercial-NoDerivatives 4.0, and commercial use requires CIS's prior approval, so a consultant or service provider delivering the Controls to clients needs to check that licensing before doing so. The cost of a program comes from the tools, staff time and services needed to meet the Safeguards, not from the Controls text itself. Your main cost questions are therefore about tooling, labor and any paid CIS membership you choose to buy.
What does SecureSuite cost and who gets it free?
SecureSuite End User membership is priced by employee count, from 2,400 US dollars a year for up to 99 employees to 20,000 US dollars a year for 100,000 or more, according to CIS's End User pricing page, which CIS notes is subject to change. CIS applies a 5% discount on 2-year and a 10% discount on 3-year memberships. End User membership does not allow client or commercial use. US state, local, tribal and territorial government entities and US public academic institutions receive membership free. The SecureSuite Controls Membership, aimed at consultants, MSPs and MSSPs, costs 3,600 US dollars a year and includes CIS CSAT Pro for tracking client implementations. Confirm current prices on the CIS site before budgeting.
Can we implement IG1 ourselves?
Often yes, if you have staff who can run the tooling and the time to document the processes. CIS's Cost of Cyber Defense guide groups the 56 IG1 Safeguards into logical categories and identifies the tool types needed, and it notes that one tool can address several Safeguards. For example, a single enterprise and software asset inventory tool can cover Safeguards 1.1, 1.2, 2.1, 2.2, 2.3, 9.1 and 12.1. Your internal costs are mostly staff time for deployment, configuration, written policies and evidence collection. Key factors are the size of your estate, the number of tools already in place and how much in-house security engineering capacity you have.
When should we hire an implementation partner and what does the partner not do?
Consider a partner when internal staff lack time or skills for a fixed set of platform deployments, integrations or hardening work, or when you need an outside team to build evidence in a defined timeframe. DeployOpen plans, implements, hardens, integrates and documents self-hosted open-source platforms inside your own infrastructure, and most engagements are fixed-scope with deliverables agreed in writing before work starts. A partner does not own your controls, write your risk decisions for you, or issue any attestation. Your organization keeps accountability for its controls, and any independent review must come from a qualified assessor.
Does a partner or auditor issue a CIS Controls certificate?
No organization can be certified against the CIS Controls, and no implementation partner can issue a certificate on CIS's behalf. CIS offers CIS Controls Accreditation, run with CREST, for SecureSuite member organizations that provide implementation, auditing or assessment services, and it lists an application fee of 1,500 US dollars for CREST members and 2,500 US dollars for non-members. That accreditation applies to the service provider, not to your environment. DeployOpen prepares systems, controls and evidence, but it does not issue audit reports, attestations or certifications. Ask any provider which accreditation or independent assessment they hold before relying on their work.
How do we get a quote for CIS Controls implementation?
Start with a written scope, because quotes follow from it. DeployOpen does not publish a price list. Prepare a list of in-scope systems and their approximate counts, the Implementation Group you are targeting, the existing tools you already license, and the evidence your customers or regulators expect. Ask each provider for a fixed-scope proposal that lists deliverables, responsibilities, assumptions and what is excluded, plus any recurring retainer for upgrades, support or testing. Compare proposals on what they cover, not on headline hours, and confirm whether licensing for commercial tools is included or billed separately.
What drives the total cost of CIS Controls IG1?
The main drivers are the number of employees, users, workstations and servers, since many commercial tools are priced that way or by usage. CIS built IG1 Enterprise Profiles to estimate costs and found that commercial tool licenses should cost less than 20% of the IT budget for enterprises of any size, according to its Cost of Cyber Defense guide. Other drivers include whether you already own endpoint, identity or backup tooling, how many environments you run, and whether you use open-source platforms that reduce license spend but add deployment and support effort. The guide's downloadable budgeting spreadsheet and per-tool appendices are the best starting point for your own estimate.
Where CIS Controls budgets usually go wrong
Most overspend on the CIS Controls comes from how purchases are made and how they are scoped, not from the Safeguards themselves. The four cards below cover tool buying, recurring renewals, MS-ISAC assumptions and vague partner scopes, which are the places where a first estimate most often drifts.
Buying one tool per Safeguard
Teams often read the 56 IG1 Safeguards as a shopping list and buy a product for each one. CIS points out that the Safeguards do not require 56 tools. For example, a single enterprise and software asset inventory tool can address Safeguards 1.1, 1.2, 2.1, 2.2, 2.3, 9.1 and 12.1. Before any purchase, map each candidate tool to the Safeguards it covers, and ask the vendor which of those it supports. Consolidate by function before requesting quotes.
Ignoring recurring license renewals
Commercial tools are usually priced per employee, user, workstation, server or by usage, and most are licensed on a recurring basis. CIS built its IG1 Enterprise Profiles around these commercial license prices, so the figures it estimates are not one-time purchases. A budget that lists only the first-year purchase will understate the cost in later years. Ask each vendor for the renewal price, the unit it is counted in, and the expected growth in headcount or endpoints. Model renewals as an annual line item, not a launch expense.
Assuming MS-ISAC services stay free
Some plans still assume that threat intelligence or sharing services from the Multi-State Information Sharing and Analysis Center cost nothing. CIS notes that MS-ISAC introduced a fee-based membership as of June 23, 2025, so references to no-cost MS-ISAC services no longer apply. Any Safeguard or process that relied on those services needs a line in the budget or a replacement source. Confirm current MS-ISAC terms directly before finalizing the budget.
Scoping partner work without written deliverables
Engagements that begin with a general request to help with CIS Controls often produce unclear invoices and unfinished evidence. A written scope should name the Safeguards in scope, the systems and business units covered, the configuration and documentation deliverables, the testing performed and the handover format. Ask for a fixed scope with agreed deliverables and timelines before work starts, and confirm which parts remain with your own staff. Agree deliverables in writing before any work begins.
What to put in a request for a CIS Controls quote
Start with the target Implementation Group, because it sets how many of the 153 Safeguards are in scope. IG1 has 56 Safeguards, IG2 brings the total to 130 and IG3 covers all 153. A request that says only "implement the CIS Controls" cannot be scoped, so state which group the organization is targeting, whether it is working toward IG1 first, and whether any Safeguards outside that group are already required by a customer or regulator. Add the employee count, the number of workstations and mobile devices, and the number of user identities, since many tool costs are priced per employee, user, workstation or server. The scope also depends on what the organization runs: a list of server counts, cloud accounts and subscriptions, SaaS applications and any operational technology or segments that need separate treatment.
Include the current tooling and the third-party list. Name the endpoint protection, identity provider, backup platform, logging and SIEM products, vulnerability scanner, email gateway and any asset inventory tool already in use, along with licence terms and renewal dates. Existing tools may cover several Safeguards, and CIS notes that one inventory tool can address multiple Safeguards, so an honest inventory of what is already deployed usually lowers the work to be done. Provide the list of service providers that hold sensitive data or run critical platforms, because Control 15 Safeguards require that they be inventoried and assessed. Also state whether any policies or the incident response plan already exist, since drafting them is a separate line in the quote.
Finally, give the deadline and its source. Name the customer contract, regulator, or internal board date that sets the timeline, and say whether the requirement is a self-declared conformance statement or a result that an independent party will review. Be explicit about roles: DeployOpen plans, implements, configures and documents the systems and evidence inside the organization's own infrastructure, the organization owns its controls and decisions, and DeployOpen does not issue reports or certificates. Any independent assessment is bought separately from an assessor of the organization's choosing. DeployOpen does not publish prices. A quote follows from the written scope, so the more complete the request, the sooner a scope can be agreed in writing before work starts.
Who owns the controls, who prepares evidence and who assesses them
The organization owns its CIS Controls program. CIS publishes the Controls as a prescriptive set of Safeguards, but nothing in the Controls transfers accountability for a Safeguard to an outside firm. Leadership accepts the risk, funds the program, and decides how each Safeguard applies to its environment. Staff run the processes that produce daily evidence, such as access reviews, patch cycles and asset reconciliation, and those processes continue long after any project ends.
- Ownership decisions: setting scope, choosing the Implementation Group to target, and accepting residual risk for each Safeguard.
- Policies and processes: approving the written processes that the assessment specification checks, and keeping them current.
- Operating controls: running the tools and workflows day to day, including alert handling and exception approvals.
- Internal assurance: tracking progress, self-assessing against the assessment specification, and correcting gaps.
- Cost of ownership: staff time and recurring licenses, which usually cost more over the years than the initial setup.
Before engaging anyone, confirm that a named internal owner can answer for each Safeguard after the project closes.
An implementation partner such as DeployOpen works inside the client's infrastructure to configure, document and prepare evidence for the Safeguards in an agreed scope. The partner does not own the controls and does not decide whether a Safeguard is met. Its deliverables are working systems, documented configurations and an evidence set that an assessor or the client's own team can review. Work is usually fixed-scope, with deliverables and timelines agreed in writing before work starts.
- Build and configure: deploying self-hosted open-source tooling in the client's cloud accounts, data centers or air-gapped networks.
- Document: writing system descriptions, configuration baselines and runbooks that match the assessment specification's measures.
- Prepare evidence: setting up collection so that logs, inventories and scan results can be produced on request.
- Test and remediate: running internal checks against the Safeguards in scope and fixing the gaps that those checks find.
- Handover and support: training staff and, where agreed, offering retainers for upgrades and ongoing support.
Ask the partner to state in writing which deliverables are configurations and documents, and which, if any, depend on the client's own staff or a third party.
An independent assessor tests whether a Safeguard is in place and operating, then reports on it. CIS does not certify organizations against the CIS Controls, so the assessor's work is usually a readiness review, a second-party assessment for a customer, or a review tied to a regulator or contract. Only an independent auditor, assessor or certification body issues reports or attestations. An implementation partner must stay separate from that role, because an assessor who designed the controls it tests cannot give independent judgment on them.
- Independence boundary: the assessor should not have built the systems or written the evidence it reviews.
- Testing: sampling records, reviewing configurations and comparing results against the assessment specification's measures.
- Reporting: issuing findings or conclusions in the form the requesting party accepts.
- Scope limits: confirming what the assessment covers and what it excludes.
- Cost drivers: scope size, sample depth and the number of Safeguards tested.
Before hiring, confirm with the party requesting the assessment which report form it will accept and whether the assessor is independent of the implementation work.
How DeployOpen works on this
DeployOpen plans and implements self-hosted open-source platforms inside your own cloud accounts, data centers or air-gapped networks, and prepares the systems and evidence that CIS Controls work depends on. Engagements are fixed-scope, so the cost components are agreed in writing before any work starts.
How we scope
- We map which Safeguards and Implementation Group your organization targets, and which tool categories those Safeguards need.
- We list the platforms, licenses and environments in scope, so you can compare them with the CIS IG1 cost categories.
- Scope, deliverables and timelines are written down and agreed before any work begins, which makes the quote traceable.
How we build
- We deploy the chosen open-source tooling inside your infrastructure, including asset inventory, logging and backup platforms where they apply.
- We configure and harden each platform against the relevant CIS Benchmarks and document every configuration decision.
- We test the controls against the Assessment Specification measures so you can see which Safeguards are evidenced and which are still open.
How we hand over
- We deliver runbooks, configuration records and an evidence map that ties each Safeguard to the artifact that shows it.
- We document the licensing and recurring costs of each tool, so your budget owner can separate one-time spend from ongoing spend.
- We brief your team on operation, and we state clearly that your organization owns its controls and any CIS self-assessment result.
How we support
- Ongoing support, upgrades and continuous testing are available as retainers after handover.
- Retainers cover platform updates when CIS publishes a new version of the Controls, so evidence keeps pace with the framework.
- Confirm with us during scoping which support level and recurring costs will apply, and request them in writing alongside the build quote.
