Symmatrics said on Oct. 22, 2026, that Andrew Hallman has joined its Strategic Advisory Board. Hallman is a former senior CIA and ODNI official and currently works at Leidos; the company says his experience will inform its cybersecurity efforts, but the announcement does not specify his duties or any product results.
Symmatrics appointed Andrew Hallman, a former senior official at the CIA and the Office of the Director of National Intelligence, to its Strategic Advisory Board, the company announced Oct. 22. The appointment brings an experienced intelligence and security figure into an advisory role at a company developing one-time-pad-based encryption products for organizations facing cyber risks, although Symmatrics did not detail Hallman’s specific responsibilities.
Hallman has more than 30 years of intelligence and security experience, according to Symmatrics. From 2015 to 2019, he served as the CIA’s Deputy Director for Digital Innovation, where he established and led one of the agency’s directorates. From 2019 to 2020, he served at ODNI as Principal Executive, performing the duties of Principal Deputy Director of National Intelligence, the company said.
Hallman currently works at Leidos Inc. as Vice President and Strategic Account Executive for the Intelligence Community, according to the announcement. Symmatrics did not say whether his advisory position will affect his work at Leidos, or provide details about the board’s membership, meeting schedule, compensation, or expected time commitment.
Symmatrics describes itself as a cybersecurity company developing products based on One-Time Pad Symmetric Key (OTPSK) encryption. It says its technology is designed to protect data in transit and at rest against AI-driven and quantum-related threats, and to support identity management for users and devices. Those descriptions are company claims; the announcement did not include independent testing, deployment figures, or performance results.
What Hallman Adds to Symmatrics
The appointment gives Symmatrics access to a senior adviser with experience in intelligence leadership and digital innovation at U.S. national security agencies. That background may be relevant as the company seeks to serve government, defense and critical-infrastructure organizations, sectors where protecting sensitive communications and networks is a priority.
For customers and potential partners, the appointment is a leadership development, not evidence that the company’s products have been adopted or validated by the intelligence community. Hallman’s government service is distinct from any endorsement by the agencies where he worked. Symmatrics did not announce a government contract, customer deployment, or technical milestone alongside his appointment.
The announcement also places the company’s pitch within concern about future encryption risks from quantum computing and present-day cyber threats involving AI. The practical significance will depend on whether Symmatrics can demonstrate that its products meet customer requirements and perform as described. The appointment itself does not establish the security properties of OTPSK or show that it can address those risks at scale.

Hallman’s Intelligence and Cybersecurity Background
Hallman’s roles span two major U.S. intelligence organizations. At the CIA, he led the Digital Innovation directorate from 2015 through 2019. At ODNI, he performed the duties of Principal Deputy Director of National Intelligence from 2019 to 2020, according to Symmatrics. The company says he also served as a principal adviser to the president on intelligence issues during that period.
Symmatrics frames its products around OTPSK encryption and a system it calls Continuously Expiring Trust™. It says the approach is intended to reduce attack surfaces and protect data and communications in the AI and post-quantum era. The company lists national security, defense, financial services, healthcare and critical infrastructure among the sectors it serves. The announcement provides no additional detail on the technology’s design, independent evaluation, or current customer base.
“Andrew’s experience leading the nation’s most critical intelligence and security initiatives makes him a valuable addition to our advisory board.”
— Walter Raquet, Symmatrics chairman and CEO

Technical and commercial details remain limited.

Product Evidence and Customer Plans
Symmatrics said organizations can learn about its cybersecurity approach or request a pilot through the company. It did not announce a date for product releases, new deployments, or further details about Hallman’s work with the board. Potential customers and partners may look for additional information on pilot terms, independent security evaluations, and how the company’s products fit into existing systems.
Any assessment of the appointment’s impact will depend on what Symmatrics discloses next about the advisory role and its technology. The announcement establishes Hallman’s appointment and his stated intention to support the company; it does not report a product launch or a change in the company’s security capabilities.
