TL;DR: CMMC Level 2 certification validates readiness at a point in time, but Exostar argues that configuration drift, informal access changes, and outdated evidence can quickly erode compliance after assessment. Sustained readiness depends on continuous control validation, change management, and documentation discipline.

Questions worth separating out
Q: How should organisations sustain CMMC compliance after certification?
A: Organisations should treat certification as the start of continuous governance, not the finish line.
Q: Why does CMMC compliance often get harder after the assessment ends?
A: Because the organisation returns to normal operating pressure while the control environment keeps changing.
Q: What do teams get wrong about CMMC documentation and evidence?
A: They often assume that a current policy set is enough, when the real requirement is consistency between written procedures and day-to-day operations.
Practitioner guidance
- Build continuous post-certification control checks Run periodic validation of the controls that supported certification, with special attention to access permissions, configuration baselines, and monitoring coverage.
- Link every change request to compliance impact review Require review of infrastructure updates, new tools, supplier additions, and workflow changes before implementation.
- Keep SSPs and operating evidence in sync Update SSPs, policies, procedures, and audit trails whenever the way people use systems changes.

Certification drift is the real post-assessment failure mode. The article correctly frames CMMC as a milestone, but the governance risk begins after certification when controls stop being actively managed. Configuration drift, process drift, and access drift are the mechanisms that turn a successful assessment into a false sense of stability. For compliance teams, the lesson is that point-in-time evidence is only useful if the underlying control state is continuously maintained.
A question worth separating out:
Q: Who is accountable for maintaining CMMC readiness over time?
A: Accountability sits with the organisation as a whole, but it must be assigned clearly across security, IT, operations, and compliance owners. If ownership is vague, drift is inevitable because no one is responsible for reconciling changes, evidence, and access decisions. Continuous readiness requires named owners, not just shared intent.
