Zscaler Public Sector CTO Chad Tetreault, a former deputy chief technology officer and deputy chief AI officer at the Department of Homeland Security, has joined Knox Systems’ Federal Advisory Board.
At DHS, Tetreault led the design and deployment of proprietary AI solutions that modernized immigration services, streamlined data operations and advanced the department’s role in responsible AI innovation. His appointment strengthens Knox’s mission to help agencies accelerate cloud and AI adoption with the compliance, speed and resilience required in federal systems, the company said.
“Chad brings a rare blend of technical depth, creativity, and mission focus,” said Irina Denisenko, CEO of Knox Systems. “He’s one of the few federal leaders who’s delivered enterprise-scale AI outcomes inside the government. His perspective will help us guide agencies through the next phase of secure digital transformation.”
At Zscaler, Tetreault leads public sector AI strategy and governance, helping regulated environments adopt and defend next-generation AI capabilities. He also serves on the MIT Gen AI Global leadership team as deputy co-lead of the Agent Dev Department, focused on democratizing AI innovation worldwide.
“Knox is solving the exact challenges that define the next era of government IT – speed, safety, and trust,” Tetreault said. “I’m excited to join the Advisory Board and help shape how agencies modernize responsibly while unlocking the full potential of AI.”
The Knox Federal Advisory Board includes senior leaders from defense, civilian and technology sectors. Tetreault joins recent appointees David Epperson, former deputy CIO of the Executive Office of the President and former deputy CIO and CISO of the Cybersecurity and Infrastructure Security Agency, and Carrie Lee, deputy CIO of the Department of Veterans Affairs.
