Sum IT Up: CMMC News Roundup

Speak With Our Team: https://summit7.us/contact



CMMC may be on hold, but cybersecurity rulemaking isn't. We break down five major requirements defense contractors need to watch, including the FAR CUI rule, CIRCIA, DFARS 252.204-7012 updates, CMMC 3.0, and post-quantum cryptography.

DoD already solved the problem of CMMC requiring NIST SP 800-171 Rev. 2 while other cybersecurity requirements moved to Rev. 3. Then it suspended CMMC Phase 2.



Now the FAR CUI rule is approaching with Rev. 3, CMMC remains tied to Rev. 2, and defense contractors could once again find themselves juggling different cybersecurity baselines for the same data. We break down how DoD got here, the options for fixing it, and why CMMC reform could make the problem even more complicated.

DoD suspended CMMC Phase 2 amid concerns about cost and burden on small businesses. Now it is hoping those same contractors will embrace cybersecurity practices that are broader, more complex, and potentially more expensive than their existing requirements.



We break down DoD's remarkable explanation for its “Brilliant at the Basics” campaign, the push toward phishing-resistant MFA and broader operational technology security, and NDIA survey data showing what defense contractors already spend implementing and maintaining NIST SP 800-171 and how many lack the resources to manage those requirements.



Will the result of the CMMC Review be a more expensive cybersecurity baseline with less assurance that it is actually being implemented?

Everyone says CMMC has an assessor shortage.



The July numbers tell a different story.



We break down the latest CMMC ecosystem data, DoD's own demand estimates, and why the real bottleneck is contractor readiness, not assessment capacity.

DoD is reconsidering CMMC assessments and talking about reducing costs for defense contractors. But months before the Phase 2 suspension, the DoD CIO published a strategy saying the Defense Industrial Base will migrate to post-quantum cryptography, CMMC will be updated to include PQC requirements, and “costs will be incurred.”



We break down why quantum computing threatens modern encryption, the federal government's 2030/2031 migration timeline, what DoD has already said about CMMC, and what the transition could eventually cost defense contractors.
