Symmatrics has appointed Andrew Hallman, a former senior CIA and ODNI official who now works at Leidos, to its Strategic Advisory Board. The company says his intelligence and security experience will inform its cybersecurity work; the announcement does not detail his specific duties or any product milestones.
Symmatrics has appointed Andrew Hallman, a former senior official at the CIA and the Office of the Director of National Intelligence (ODNI), to its Strategic Advisory Board. The company says Hallman’s national security experience will inform its work on cybersecurity products based on one-time-pad encryption, which it markets for threats associated with artificial intelligence and future quantum computing.
Hallman brings more than 30 years of intelligence and security experience, according to Symmatrics. He served as the CIA’s Deputy Director for Digital Innovation from 2015 to 2019, where he led a newly established directorate, the company’s announcement says. From 2019 to 2020, he served at ODNI as Principal Executive and performed the duties of Principal Deputy Director of National Intelligence.
Hallman is currently Vice President and Strategic Account Executive for the Intelligence Community at Leidos, a position identified in the company’s announcement. Symmatrics did not specify whether he will leave that role or describe the time commitment and scope of his advisory work.
Symmatrics says it is developing products using One-Time Pad Symmetric Key (OTPSK) encryption, intended to protect data in transit and at rest. The company also describes its offerings as incorporating device and user identity management and a system it calls Continuously Expiring Trust. Those descriptions and security benefits are company claims; the announcement provides no independent testing results, customer deployments, or technical evaluation.
A National Security Adviser for Symmatrics
The appointment gives Symmatrics an adviser with senior experience across U.S. intelligence and digital security as the company seeks to serve government, defense, and other high-risk sectors. Hallman’s background may be relevant to how the firm presents its products to prospective customers in those markets, but the announcement does not say he will direct product development, government relations, or sales.
The move also puts the company’s work in the wider debate over how organizations should prepare for AI-enabled cyber risks and future quantum computing. Symmatrics argues its encryption approach can address those concerns. The appointment itself, however, is not evidence that its technology has been independently validated or adopted by public agencies.

Symmatrics’ Encryption Strategy
Symmatrics describes itself as a cybersecurity company developing encryption products around One-Time Pad Symmetric Key technology. The company says its approach is designed to secure data both in motion and at rest and to reduce attack surfaces. The announcement does not provide technical detail sufficient to assess those claims or explain how the products are deployed at internet scale.
Its stated target markets include national security, defense, financial services, healthcare, and critical infrastructure. The company frames its products as preparation for current AI-driven attacks and future post-quantum security needs. The announcement of Hallman’s appointment was reported by The Quantum Insider on October 22, 2026, based on a Symmatrics press release.
“Andrew’s experience leading the nation’s most critical intelligence and security initiatives makes him a valuable addition to our advisory board.”

The Adviser’s Role and Product Proof
The announcement does not state when Hallman’s appointment takes effect, how often the board will meet, or what advice he will provide. It also does not address whether his position at Leidos will change or whether he has any financial interest in Symmatrics.
Symmatrics did not disclose new contracts, deployments, revenue, or independent assessments of its encryption products alongside the appointment. Its statements that the technology is resistant to AI-driven threats and secure against quantum-related risks remain company claims in the supplied announcement; further evidence and technical detail were not provided.

Evidence of Deployment and Advisory Work
The next developments to watch are any details Symmatrics releases about Hallman’s responsibilities, the board’s advice, and the company’s product development or customer deployments. The company says it offers organizations a no-obligation pilot, but the announcement does not name prospective or current pilot participants.
Until Symmatrics or an independent evaluator publishes further information, the appointment is best understood as a leadership and advisory-board announcement, not a product launch or confirmation of the technology’s performance. No additional milestones or dates were announced.
