Knox Systems has announced that David Epperson, former Deputy Chief Information Officer to the Executive Office of the President at the the White House, former Senior Presidential Transition Advisor at the White House Military Office, and the first Chief Information officer and Security Officer of the Cybersecurity and Infrastructure Security Agency, currently the Sr. VP for National Security at H2O.ai has joined the company’s Federal Advisory Board.
Epperson is among the longest-serving cybersecurity leaders in the federal government, with over three decades overseeing technology and security transformation across White House, DHS, IC, CISA, and the Department of War.
His appointment reinforces Knox’s commitment to helping agencies accelerate digital modernisation while maintaining the highest standards of national security and compliance.
“David’s experience sits at the centre of where federal cybersecurity, infrastructure, and innovation meet,” said Irina Denisenko, CEO of Knox Systems. “As agencies expand their use of AI and cloud-based services, his insight will help ensure Knox continues to deliver technology that strengthens the mission- securely and at scale.”
At CISA, Epperson led the agency’s technology and cybersecurity programs during a period of historic expansion, laying the foundations for its modern IT and cyber defence operations.
Before that, he served as Deputy Chief Information Officer for EOP, driving policy, risk management, and zero-trust modernisation across one of the government’s most complex environments.
“Knox has proven what’s possible when compliance and innovation move together,” said David Epperson. “I’m honoured to join the Advisory Board and help shape the next phase of secure AI and cloud adoption across government.”
The Knox Federal Advisory Board brings together senior defence, civilian, and technology leaders to guide the company’s strategy as agencies navigate the convergence of AI, cybersecurity, and compliance.
The board provides insight on evolving FedRAMP, NIST, and DoW frameworks, ensuring Knox solutions remain aligned with the government’s most rigorous standards.
