PKF O’Connor Davies (“PKFOD”) (“the Organization”), one of the nation’s largest accounting, tax and advisory practices, is pleased to announce it has achieved fully authorized status from the CyberAB as a CMMC 3rd Party Assessment Organization (C3PAO). As an authorized C3PAO, the organization will now be able to certify companies for CMMC Level 2 compliance.

The Cybersecurity Maturity Model Certification (CMMC) is a third-party certification program designed to certify defense contractors’ information systems for compliance against a best practices list of security controls intended to protect controlled unclassified information (CUI). These best practices are an effort by the Department of Defense (“DoD”) to shore up the defense supply chains against increasingly sophisticated attacks from both domestic and foreign actors.

To earn this authorization, the organization underwent a rigorous audit by the DoD’s Defense Industrial Base Cybersecurity Assessment Center (DIBCAC) group and achieved a perfect assessment score.

“We are grateful to the DoD and the CyberAB for their support and are eager to join the community of authorized C3PAOs providing this important service to the defense industrial base,” said Nick DeLena, Partner in the Cybersecurity and Privacy Advisory group. “This is the culmination of a years-long effort and represents our longstanding commitment to helping companies in the defense supply chain with these complex requirements.”

“The cyber threat landscape is constantly evolving.” said Thomas DeMayo, Partner and leader of the firm’s Cybersecurity and Privacy Advisory group. “We have a long history providing services like penetration testing, digital forensic services, cybersecurity risk assessments and virtual Chief Information Security Officer services to the defense sector. We are proud to add CMMC Level 2 certifications to our service offerings.”
