A CMMC GRC tool is software that helps you organize the governance, risk and compliance work behind a CMMC program: the requirements, the policies, the evidence, the plans, the findings and the reports. Tools in this space do very different things under the same label. Some track checklists. Some pull data from your systems. Some are built for a dozen frameworks at once. This guide explains what to look for, how the main kinds of tools differ, and where Continu-US fits.
What a GRC tool does for CMMC
GRC stands for governance, risk and compliance. In a CMMC program the three parts look like this:
- Governance: who owns what. Policies, procedures, roles, the System Security Plan, and the customer’s and providers’ responsibilities.
- Risk: what is wrong and what you are doing about it. Findings, plans of action and milestones, risk decisions, and who accepted what.
- Compliance: whether the requirements are met and how you know. Mapping to the 110 NIST SP 800-171 requirements and their assessment objectives, evidence, scores and reports.
A good tool keeps those three connected, so a finding links to the objective it affects, the evidence behind it and the plan that closes it.
What a GRC tool does not do is decide whether you meet a requirement. That decision belongs to the assessor. A tool can organize evidence, show gaps and keep records straight. It cannot make an organization compliant or certified, and any vendor who implies it can is selling you something the rule does not allow.
Features worth looking for in a CMMC GRC tool
Buyer guides tend to list the same basics: mapping to the controls, gap analysis, integrations with your existing tools, live dashboards, regular updates as the standards change, and room to grow. Those matter. Beyond them, these are features worth looking for in a CMMC GRC tool.
- Objective-level mapping. Evidence tied to each NIST SP 800-171A assessment objective, not only to the requirement.
- Evidence collected from your systems. Dated, repeated and sourced, so you can see change over time.
- A clear status for every objective. Including a visible “not yet verified” state for anything a system can’t check.
- Scoring. The SPRS score and the CMMC score, calculated from the same results.
- POA&M tracking. Findings, owners, closeout dates, and a view of which gaps are eligible.
- SSP generation. A System Security Plan built from live data and reviewed by a person.
- Inheritance and shared responsibility. Provider-handled controls recorded by name, with what the customer still owns.
- A document register. Policies, procedures and plans with version history and review dates.
- Recurring activities. Access reviews, log reviews and training with owners and due dates.
- Reporting. Regular status reports and packaged evidence you can hand to an assessor.
- An audit log. Every change, decision and export recorded.
- Deployment you can explain. Where the data lives, what the tool can read, whether it stores credentials, and whether it works in your cloud, including a government cloud if you use one.
- Other frameworks. Support for any others you need, such as PCI DSS or NIST SP 800-53, from the same evidence.
A tool should help you prepare and keep records current. It should not promise an outcome.
The kinds of tools on the market
Every approach to CMMC covers part of the problem. These are the main ones, and what each tends to do well.
- Point-in-time assessments and readiness reviews. A person checks your environment on specific days. These verify controls against the objectives and they are essential. They are also a snapshot, taken once per cycle.
- Scheduled scans. Vulnerability, configuration and STIG or SCAP scans check technical settings on a schedule. They verify settings well, but they map to scan rules, not to assessment objectives, and they say nothing about policies or procedures.
- Outside-in risk ratings. These score an organization from signals visible on the internet. They can run continuously, but they never see inside your environment, so they cannot verify an internal control.
- GRC and compliance automation platforms. These organize requirements, policies, evidence, tasks and reports, usually for many frameworks at once. They are the closest match to what people mean by a “GRC tool.”
The two best-known compliance automation platforms, Drata and Vanta, both now offer CMMC support. Going by their public product pages as of October 2026:
- Vanta describes coverage of CMMC Levels 1, 2 and 3, controls pre-mapped to NIST SP 800-171, continuous evidence collection with automated tests, policy templates, guided SSP creation, POA&M templates, an SPRS dashboard, and subcontractor risk assessment. Its page says the content currently aligns to 800-171 Rev 2.
- Drata describes centralized evidence and testing artifacts, POA&M tracking with owners and status, readiness workflows, monitoring for control drift, supplier assessment, and support for self-assessments and third-party reviews.
Both are broad, multi-framework platforms, which is a real strength if you also need other attestations. Both are hosted by the vendor. The questions that matter for a defense contractor are the ones in the feature list above: how deep the mapping goes, what happens to objectives a tool cannot check, where your data sits and which cloud it works in. Neither page I reviewed discussed government cloud environments, so confirm that directly with any vendor if it applies to you.
These descriptions come from vendor marketing pages. Treat them as claims to verify in a demo, not as measured results.
How the approaches compare
Most teams end up in one of three places: running the program by hand, buying a GRC platform, or using a verification platform like Continu-US. The table rates each in general terms, using the features above. It describes typical tendencies, not every product in a category, so check any vendor against your own list.
| Approach | Continuous control evaluation | Verifies the control | Mapped to objectives | Inside the owner’s boundary | Assessor-ready evidence |
|---|---|---|---|---|---|
| Manual: SharePoint or another repository, spreadsheets, folders, screenshots, assigned tasks | No | No, a person attests | Only as far as someone maintains it | Yes | Built up before each assessment |
| GRC platforms | Partial | Partial | Yes | Typically vendor-hosted | Partial |
| Continu-US | Yes | Yes | Yes | Yes | Yes |
“Assessor-ready evidence” here means evidence packaged so an assessor can review it. It does not mean the assessor will find a requirement met. That judgment is theirs.
Doing it by hand works, and it is where most programs start. It depends entirely on people remembering to collect, date and update everything. Platforms reduce that work and organize it, but the breadth they offer tends to be partial on verification. Continu-US is built to collect and verify the controls it can check, and to say plainly where it can’t.
Where Continu-US fits
Continu-US isn’t a GRC platform. It is a continuous monitoring and verification platform. But it covers most of what a CMMC shop buys a GRC tool for, and its evidence is primarily collected automatically, not only uploaded.
That last point is the difference that matters most. The platform reads your environment and records what it finds against each assessment objective, with a date and a source. Where a system can’t speak for itself, you can still drop in screenshots and files per objective. Everything lands in one place, tied to the same objectives.
| Area | What’s included |
|---|---|
| Controls and frameworks | All 320 NIST SP 800-171A objectives (CMMC Level 2), plus PCI DSS 4.0.1 and NIST SP 800-53 Rev 5 Moderate, from the same evidence through reviewed crosswalks. Control mapping per objective: what evidence covers it, what’s failing, and what could count once collected. Tailoring: not applicable, or inherited fully or partly from a provider, with justifications. A verification matrix showing each objective as automatically verified, technically informed, documentary or not yet verified. |
| Continuous evidence collection | 70+ Microsoft 365, Entra, Intune, Defender, Exchange, Purview and Azure checks, read-only, with no stored secrets. AWS, Google Cloud, Google Workspace and email DNS (SPF, DKIM, DMARC). Windows, Windows 365 and Linux endpoint check scripts, hash-pinned and enrolled per device. FortiGate, FortiSwitch and Cisco network device configuration analysis. Jira, ServiceNow and SharePoint change and vulnerability boards (approvals, security impact analysis, remediation on time). Elastic, Sentinel and Huntress incident and alert evidence. |
| Assessment and scoring | SPRS score calculated with the DoD Assessment Methodology, including its partial-credit items and its handling of a missing SSP, plus the CMMC score. The DoD self-assessment workbook filled in for you. CMMC Conditional Level 2 POA&M eligibility, with what’s blocking it. Quarterly control assessment report in HTML and Excel, in internal and audit versions. |
| Documentation | An SSP generated from the platform: system profile, inventory, out-of-scope assets, placeholders filled. A document register for policies, procedures and plans, with version history, file hashes, review dates and one-click review stamping. Documents mapped to the objectives they support, with documentation-only objectives flagged for review. Evidence artifacts added per objective. |
| Risk and remediation | A POA&M register with per-system ID prefixes, closeout limits and CMMC eligibility. Findings from drift, with false-positive and exception handling and justifications. Stated versus verified: what your implementation statements say, compared with what the evidence shows. |
| Ongoing operations | Recurring activities with owners and due dates (access reviews, log reviews, scans, training). A Monday status email and a week-to-date report. An overview showing posture, SPRS trend and what needs attention. |
| Assessor-ready output | An evidence package with every file in a SHA-256 manifest and readable HTML views, organized by source or by objective. A full audit log of every change, decision and export. |
| Deployment and trust | Runs in your own Azure tenant (Commercial or Government) as a managed application, so data stays in your boundary. Read-only access throughout, with no passwords or secrets stored for cloud connections. Built and run by a C3PAO and CMMC Certified Assessor, with the mapping done by an assessor, not a marketer. |
One feature deserves a second look: stated versus verified. In many programs the SSP says one thing and the environment says another, and nobody compares them until an assessor does. Putting the two side by side, continuously, is the core of what the platform is for.
Being built by a C3PAO means the mapping comes from assessor experience. It does not mean a purchase has any bearing on how an assessment turns out.
What Continu-US covers and what it doesn’t
For CMMC Level 2, it covers the scoring, documentation, POA&M and evidence an assessment needs, and keeps them current between assessments.
What it does not do:
- It does not replace a full enterprise GRC suite’s vendor-risk or policy-attestation workflows.
- It does not make an organization compliant or certified, and it does not decide whether an objective is met. The assessor decides.
- It does not replace people. Objectives that rest on a policy, a training record or a judgment call still need a human and a document, and the platform marks them that way.
- It does not cover every framework. It covers NIST SP 800-171A and CMMC Level 2, PCI DSS 4.0.1 and NIST SP 800-53 Rev 5 Moderate. If you need others, ask us.
- It is not a substitute for an assessment.
What is planned, not shipped:
- PCI scope and inventories
- Service provider (AOC) tracking
- A targeted risk analysis register
- Tenable and repo / CI connectors (GitHub, Azure DevOps, Bitbucket) for secure development evidence
If one of these decides your purchase, ask us where it stands rather than assuming.
Questions to ask any vendor
Use these on every tool you evaluate, including ours.
- Does it map evidence to each assessment objective, or only to the requirement?
- Show me an objective the tool cannot verify. How is it labeled?
- Where does my data live, and what can the tool read in my environment? Does it store credentials?
- Does it work in my cloud, including a government cloud if I use one?
- How does it handle POA&M eligibility, not just tracking?
- Is the SSP generated from live data, and who reviews it?
- How do inherited controls get recorded, and with what evidence?
- What is the audit trail for a changed status or a waived item?
- Which version of the control catalog does it follow, and how do updates reach me?
- What does the vendor say it guarantees? (The right answer is nothing about outcomes.)
Frequently asked questions
Is Continu-US a GRC tool? Not strictly. It is a continuous monitoring and verification platform, not a GRC platform. But it covers most of what a CMMC team buys a GRC tool for (scoring, documentation, POA&M and evidence), and the evidence is collected from your systems, not uploaded. It does not replace an enterprise suite’s vendor-risk or policy-attestation workflows.
Do I need a GRC tool for CMMC? No tool is required. You can run a program on well-kept documents and spreadsheets. A tool helps most with evidence that has to stay current and with keeping many moving parts connected.
Can a tool make me CMMC compliant? No. A tool can collect and organize evidence and show gaps. Whether an objective is met is the assessor’s decision.
How is this different from Drata or Vanta? They are broad, vendor-hosted platforms covering many frameworks. Continu-US is narrower, runs inside your own Azure tenant, and puts verification against assessment objectives first. Which fits depends on your frameworks, your cloud and how much you need verified from systems.
Does buying Continu-US affect my assessment? No. ATLLC is a C3PAO, and buying Continu-US has no bearing on any certification outcome.
