Symmatrics has appointed Andrew Hallman, a former senior CIA and ODNI official who now works for Leidos, to its Strategic Advisory Board. The company says his intelligence and security experience will inform its cybersecurity work; the appointment does not independently verify Symmatrics’ claims about its encryption products.
Symmatrics has appointed Andrew Hallman, a former senior official at the CIA and Office of the Director of National Intelligence who now works at Leidos, to its Strategic Advisory Board. The cybersecurity company says it is developing one-time-pad encryption products for organizations facing AI-related and future quantum-computing risks; the announcement does not include independent testing or performance results for those products.
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 directorate, and from 2019 to 2020 held a senior role at ODNI, performing the duties of Principal Deputy Director of National Intelligence. Symmatrics said he is currently a vice president and strategic account executive for the Intelligence Community at Leidos.
The appointment is to an advisory board, not an operational or executive position, and the announcement does not specify the board’s responsibilities, Hallman’s expected time commitment, or the terms of his appointment. Symmatrics Chairman and CEO Walter Raquet said Hallman’s experience would help guide the company’s efforts to develop technologies for governments, enterprises and critical infrastructure.
Symmatrics describes its product approach as One-Time Pad Symmetric Key (OTPSK) encryption, combined with identity management for devices and users. The company says its technology is designed to protect data both in transit and at rest and to address AI-driven attacks and post-quantum security concerns. Those descriptions are company claims; the announcement provides no technical evaluation, customer case studies, or independent evidence establishing the products’ security or effectiveness.
What Hallman Adds to Symmatrics
Hallman’s appointment gives Symmatrics a senior adviser with experience in U.S. intelligence leadership and digital innovation, areas relevant to the company’s stated focus on government and other high-risk customers. His background may help the company understand how potential public-sector clients assess security needs, procurement and operational constraints. That is a possible strategic benefit, not a disclosed outcome of the appointment.
The development also puts a prominent national-security figure alongside a company making ambitious claims about encryption in an era of AI and quantum computing. For customers and observers, the distinction matters: an adviser’s credentials are not a validation of a product. The announcement confirms Hallman’s appointment and summarizes his career, but it does not establish that Symmatrics’ systems have been adopted by government agencies or independently shown to withstand specific threats.

Symmatrics’ Encryption Strategy
Symmatrics says it is building cybersecurity products around OTPSK encryption and a framework it calls “Continuously Expiring Trust.” The company presents these tools as a way to reduce exposure to attacks and protect sensitive communications and stored information. Its announcement says it serves or targets sectors including national security, defense, financial services, health care and critical infrastructure.
The company’s framing reflects two concerns it identifies: attacks that use artificial intelligence and the longer-term possibility that advances in quantum computing could challenge some encryption methods now in use. The appointment announcement offers no product launch date, deployment figures or details about how Symmatrics’ system compares with existing approaches. It also does not describe the patents referenced by the company or provide the scope of any independent security assessment.
In the press release, Hallman’s career history includes his CIA role from 2015 to 2019 and service at ODNI from 2019 to 2020, when he performed the duties of Principal Deputy Director of National Intelligence. He has since taken an intelligence-sector role at Leidos. These positions provide relevant professional context, but do not indicate that the CIA, ODNI, Leidos or any government body endorses Symmatrics.
“Andrew’s experience leading the nation’s most critical intelligence and security initiatives makes him a valuable addition to our advisory board.”

Product Evidence and Advisory Duties
The announcement does not clarify what Hallman will do as an adviser, how often the board will meet, or whether he will advise on product development, market strategy or government engagement. Symmatrics also did not disclose financial terms or say whether the role is paid.
Questions remain about the company’s technology. The release does not provide technical specifications, independent testing, named customers, deployment results or a timetable for product availability. Its descriptions of OTPSK as AI-resistant and quantum-secure should be understood as company and appointee characterizations, not as independently established conclusions. No endorsement by Hallman’s former agencies or current employer was stated.

Next Steps for Symmatrics
Symmatrics said organizations can request a pilot, but it did not announce a schedule for pilots, product releases or further technical disclosures. The next developments to watch are whether the company publishes product specifications or independent security assessments, and whether it identifies customers or deployments.
For Hallman’s appointment, the company has not announced a first board meeting or described upcoming advisory work. Further detail from Symmatrics about the board’s remit and the evidence supporting its product claims would help clarify what the appointment means in practice.
