The certification was achieved following an independent assessment by a Certified Third-Party Assessor Organization (C3PAO1), in which the team secured a perfect score of 110/110 (the full set of security requirements specified under NIST SP 800-171), demonstrating a high level of operational maturity, governance, and disciplined execution across security processes and controls. Developed by the U.S. Department of Defense, the CMMC framework is designed to strengthen cybersecurity across the Defense Industrial Base and safeguard Controlled Unclassified Information (CUI). The certification requires organizations to demonstrate that cybersecurity controls are not only implemented, but also consistently applied and effective in operational environments. Strengthening readiness for mission-critical and complex defense programs Third party CMMC Level 2 certification becomes a mandatory requirement for applicable DoD contracts involving Controlled Unclassified Information (CUI) beginning with Phase 2 of the CMMC rollout in November 2026. By achieving certification ahead of that deadline, Atos positions itself to compete for larger, more security-sensitive programs while reinforcing its position as a trusted partner for organizations operating mission-critical and complex defense environments. Michael Grunberg, head of Atos in North America, said: “Achieving CMMC Level 2 certification reflects the operational discipline, security culture, and commitment to trust that our customers expect from Atos. As organizations face increasingly sophisticated threats and evolving compliance requirements, this certification further strengthens our ability to support mission-critical operations that demand resilience, security, and regulatory confidence.” This milestone builds on Atos' broader commitment to digital trust, cybersecurity excellence, and helping customers confidently manage risk in an era defined by accelerating technological change, expanding attack surfaces, and growing regulatory expectations. By combining deep cybersecurity expertise, operational rigor, and a strong culture of compliance, Atos continues to help organizations strengthen resilience, protect critical assets, and maintain confidence in their most sensitive digital environments. *** Atos Group’s cybersecurity services and products As a global cybersecurity leader with more than 6,500 experts and 205 cybersecurity patents, Atos Group helps organizations navigate the evolving threat landscape with end-to-end, AI-powered security, enabling their pursuit of digital sovereignty and trust.
