What does CMMC compliance software actually do, and does a ten-person shop need it or a spreadsheet?

CMMC compliance software primarily automates the documentation, tracking, and reporting of your cybersecurity posture, which a ten-person shop may or may not need depending on the complexity of its operations. These platforms help manage the 110 requirements of NIST SP 800-171 Revision 2 for CMMC Level 2 by organizing policies, procedures, and evidence. Assessors want to see evidence that your controls are implemented and operational, not just documented. This includes live demonstrations of security tools, access logs, configuration files, and records of regular audits and employee training. Small shops often waste money on features they do not need, like advanced continuous monitoring for complex networks, or on tools that duplicate existing IT infrastructure capabilities. For CMMC Level 2, a self-assessment is conducted every three years, and the CMMC Status is valid for three years from the CMMC Status Date. If your shop has a solid system security plan and a well-maintained shared folder of evidence, a dedicated CMMC software might be overkill, but it depends on how efficiently you can produce and present that evidence during an assessment.

A CMMC compliance platform is a tracker. It doesn't implement a single control for you, so for a ten-person shop a solid system security plan plus an organized evidence folder covers the same ground, as long as somebody keeps it current.

The assessment runs off NIST SP 800-171A, and every assessment objective gets checked by examine, interview or test. Examine is your policies, SSP, screenshots and logs. Interview is the assessor asking your people how they actually do it. Test is the part a folder can't fake: show MFA firing on a remote login, the disabled account of someone who left, audit logs getting reviewed, a laptop that can't reach the CUI share. Map each objective to its artifact and to the person who demos it.

Where small shops burn money:
- monitoring that repeats what your email platform and endpoint tools already log
- a policy library nobody tailors, which interviews expose fast
- skipping scoping. 32 CFR 170.19 sets which assets are in scope, and no tool draws that line for you. If the platform stores CUI, it's in scope too.

One correction on the other answer: Level 2 isn't automatically a self-assessment. The solicitation sets self-assessment or a C3PAO certification assessment, so ask the prime which one flows down to you.

We ran the spreadsheet route for two small clients. It works when one named person owns the updates. When nobody owns it, software doesn't fix that.
