S3 AeroDefense has achieved Level 2 certification under the Cybersecurity Maturity Model Certification (CMMC) program, following a successful third-party audit conducted by a Certified Third-Party Assessment Organization (C3PAO).
The CMMC framework, established by the U.S. Department of War (DoW), requires contractors within the defense industrial base to demonstrate their ability to safeguard sensitive government information, including Federal Contract Information (FCI) and Controlled Unclassified Information (CUI).
The Level 2 certification confirms S3’s implementation of the 110 security practices aligned with NIST SP 800-171, the federal standard for protecting controlled information across defense supply chains.
Achieving CMMC Level 2 certification enables S3 AeroDefense to support DoW programs and contracts that require compliance with the CMMC framework, positioning the company to participate in a broader range of defense sustainment and supply chain opportunities.
“This certification represents a significant milestone for our organization,” said Aksel Sidem, President of S3 AeroDefense. “Our customers trust us to deliver mission-critical support, and that includes protecting the sensitive information that supports defense programs. Achieving CMMC Level 2 demonstrates our commitment to security, accountability, and operational excellence.”
As the CMMC framework continues to roll out across the defense industrial base, relatively few companies have completed third-party Level 2 certification. By achieving certification now, S3 AeroDefense is well positioned to support partners and customers preparing for future compliance requirements.
With this milestone, S3 AeroDefense strengthens its ability to support programs involving Controlled Unclassified Information across a range of aerospace and defense platforms. The certification reinforces the company’s role as a trusted partner to OEMs, contractors, and allied operators worldwide seeking secure and reliable sustainment solutions.
