The cybersecurity landscape for defense contractors is facing seismic shifts in 2025 as CMMC enforcement brings unprecedented scrutiny to organizations across the defense supply chain. In a recent episode of Miller Mindset, BitLyft’s Founder & CEO, Jason Miller and cybersecurity expert Robert McVay broke down the current state of Cybersecurity Maturity Model Certification, offering critical insights every business needs to know.
A dangerous misconception among organizations is treating CMMC preparation as a one-time project. In reality, it requires a cultural shift toward operational maturity. The requirement for NIST 800-171 controls has been in place since January 1, 2018, yet many businesses are still scrambling to meet requirements in 2025.
CMMC compliance isn’t about showing up prepared on audit day, it’s about proving consistent adherence to documented security procedures year-round. Treating compliance as an ongoing process instead of a static goal is the only way to succeed.
Under updated CMMC rules (32 CFR Part 170), company leaders must personally attest to compliance, accepting individual liability under the False Claims Act. This isn’t theoretical. One company was fined $4.5 million after falsely claiming a perfect compliance score while their actual score was in the negative. Beyond fines, violations can result in debarment and reputational damage across the defense ecosystem.
Many organizations misunderstand what qualifies as Controlled Unclassified Information (CUI). CUI is specifically designated by the federal government—it does not include proprietary company data unless marked as such. Misinterpreting this distinction can lead to over-scoping compliance efforts and unnecessary costs.
Cybercriminals often exploit supply chain weaknesses, targeting small vendors as entry points to larger defense networks. Even a company making commercial-grade parts can become part of an attack surface if their products support defense applications. Publicly available contract data makes supply chain mapping easy for sophisticated adversaries.
A successful compliance program requires more than deploying technology. Organizations should focus on:
CMMC assessors evaluate more than firewalls and MFA configurations. They examine whether your organization follows its policies consistently. If your policy requires monthly log reviews, be ready to produce documentation proving those reviews happened.
The partnership with your Certified Third-Party Assessor Organization (C3PAO) matters. Key factors include:
Non-mega breaches now cost organizations between $4.5 million and $9.8 million on average. Add False Claims Act penalties, and a single incident could exceed $15 million. Investing in robust cybersecurity now helps avoid catastrophic costs later.
CMMC compliance is not a destination, it’s an ongoing process. Successful organizations integrate NIST 800-171 controls into daily operations, ensuring that compliance becomes part of business-as-usual.
If your organization handles CUI or plans to bid on DoD contracts, begin preparing now. Perform a thorough self-assessment, engage experienced consultants, and choose a C3PAO that aligns with your goals. Treat CMMC as an opportunity to build a resilient cybersecurity program not just another regulatory hurdle.
