Symmatrics announced Oct. 22, 2026, that Andrew Hallman has joined its Strategic Advisory Board. Hallman, a former senior CIA and ODNI official who now works at Leidos, brings more than 30 years of intelligence and security experience; the company says his perspective will inform its cybersecurity work.
Symmatrics announced on Oct. 22 that Andrew Hallman, a former senior official at the CIA and Office of the Director of National Intelligence (ODNI), has joined its Strategic Advisory Board. The appointment brings an experienced intelligence and security leader to the cybersecurity company as it develops products based on One-Time Pad Symmetric Key (OTPSK) encryption; the announcement does not describe a specific product launch or contract tied to Hallman’s role.
Hallman has more than 30 years of intelligence and security experience, according to Symmatrics. From 2015 to 2019, he served as Deputy Director of the CIA for Digital Innovation, where the company says he established and led one of the agency’s newer directorates. From 2019 to 2020, he served as Principal Executive at ODNI, performing the duties of Principal Deputy Director of National Intelligence and advising the president on intelligence matters.
Hallman is currently Vice President and Strategic Account Executive for the Intelligence Community at Leidos, the company said. Symmatrics did not provide details about the advisory board’s size, meeting schedule, compensation arrangements, or Hallman’s specific responsibilities. His appointment is an advisory role, and the announcement does not say that he has joined Symmatrics as an employee or executive.
Symmatrics describes its work as developing cybersecurity products using OTPSK encryption to protect data and communications. The company says its technologies are intended to address risks associated with artificial intelligence and future quantum computing, and that its approach includes device and user identity management. Those security benefits are company claims; the announcement includes no independent product evaluation, performance data, or customer results.
What Hallman Adds to Symmatrics
The appointment gives Symmatrics an adviser with experience in intelligence operations, digital innovation and national security leadership. That background may be relevant to a company seeking to serve government, defense and critical-infrastructure organizations, which must protect sensitive information and communications. Hallman’s current work with the intelligence community at Leidos also places him in a sector Symmatrics identifies as part of its target market.
For readers and potential customers, however, an advisory appointment is not evidence that a product meets a security standard or has been adopted by government agencies. The announcement provides no details of a pilot, procurement, or deployment resulting from Hallman’s involvement. Its significance for Symmatrics will depend on what role he takes and whether the company can demonstrate that its products perform as described.

Symmatrics’ Encryption Approach
Symmatrics says it is building cybersecurity products around One-Time Pad Symmetric Key encryption and a system it calls “Continuously Expiring Trust.” It describes the products as designed to protect data both in motion and at rest, and to reduce attack surfaces that could be targeted by AI-enabled threats or quantum computing. The supplied announcement does not explain the technical implementation, provide test results, or identify independent assessments of those claims.
The appointment comes amid industry and government attention to the potential effects of quantum computing on some widely used encryption methods, as well as the use of AI in cyber operations. Symmatrics says it serves or targets organizations in national security, defense, financial services, healthcare and critical infrastructure. The announcement presents Hallman’s experience as relevant to that strategy, but does not report a change to the company’s product roadmap or 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

Questions About the Advisory Role
The announcement does not say how Hallman will advise the company, how often the board will meet, or whether his appointment is paid. It also does not describe any specific product, customer engagement or policy initiative he will work on. Symmatrics did not announce a contract or government endorsement connected to the appointment.
The company’s statements that its technology is “AI resistant” and “quantum secure” are descriptions of its intended protections, not independently demonstrated findings in the supplied material. No technical specifications, third-party security review, benchmark, or deployment evidence is included. It remains unclear how the products compare with other encryption approaches or what practical protections they provide in operational settings.

Evidence Behind the Product Claims
Symmatrics said organizations can learn about its cybersecurity approach or request a no-obligation pilot. The company’s announcement did not give a timeline for pilots, product releases, or further disclosures about Hallman’s board work. Future details about testing, customer deployments and the advisory board’s activities would help clarify the practical impact of the appointment.
For now, the confirmed development is Hallman’s addition to the Strategic Advisory Board. Whether his experience leads to changes in Symmatrics’ technology, customer relationships or government-sector work has not been stated.
