If CMMC has a paperwork heart, it's these two documents. The System Security Plan (SSP) describes how you meet each NIST 800-171 control; the Plan of Action & Milestones (POA&M) lists the ones you don't yet and how you'll close them. Both remain required in 2026 as part of self-assessment.
Book a 15-minute review →The SSP is the document an assessor, a prime, or a contracting officer will ask for first. It documents your environment, your system boundary, and control-by-control how each of the 110 requirements is satisfied. A vague or outdated SSP is the fastest way to fail a review - it has to match what's actually running.
The POA&M is your honesty mechanism: it acknowledges the controls you haven't met and commits to a timeline. Handled well, it's a strength - it shows an assessor a credible, managed path. Certain high-impact controls, however, generally cannot be deferred to a POA&M, so scoping matters.
The chronic problem is drift. You write an SSP, your environment changes, and within months the document describes a system that no longer exists. Because a future assessment measures reality, a stale SSP is a liability dressed up as compliance.
MDRwatchdog generates your SSP and POA&M from live monitoring and keeps them current automatically - controls the platform can prove are marked evidenced, the rest flagged into your POA&M with the gap clearly stated. What you hand over reflects your real environment. Readiness and evidence, not certification, and not legal advice.
The SSP describes how you meet each control; the POA&M lists the controls you haven't met yet and your plan to close them. You need both for a complete CMMC / NIST 800-171 self-assessment.
Yes. They're part of the self-assessment regime, which the July 2026 CMMC Phase 2 suspension left in force.
No. Certain high-impact controls generally cannot be deferred to a POA&M and must be met outright. Scoping and prioritization matter - confirm specifics against current NIST/DoD guidance.
MDRwatchdog provides security monitoring and compliance evidence to support readiness. It is not a certification and not legal advice. Certification and formal audits are performed by the appropriate authorized bodies (a C3PAO for CMMC, a licensed CPA firm for SOC 2, an accredited body for ISO 27001).
