NSA Certified Rajant Cryptographic Subsystem
The PT-100 subsystem, featuring the Wolverine Cryptographic Module, is now cleared to protect secret-level military data.
Updated on Sept. 29, 2026 in Cybersecurity
The National Security Agency has certified the Rajant PT-100 Cryptographic Subsystem for the protection of secret-level government data. This technology is designed for integration into specialized military communications hardware.
Why it matters
The certification allows the PT-100 to be utilized within the Armed Forces Counter-Rocket, Artillery and Mortar Warning system, enhancing secure communication capabilities in critical defense networks. The project was sponsored by the Counter-Unmanned Aircraft Systems Program Office to bolster operational security.
The system utilizes the Wolverine Cryptographic Module embedded within the PT-100 unit. The hardware has been approved for international interoperability, with the certification releasable to partners in Australia, Canada, and NATO.
The players
Rajant
A networking technology company based in Malvern, Pennsylvania, that specializes in mobile mesh radio systems for military and industrial use.
National Security Agency
The United States intelligence agency responsible for global monitoring, collection, and processing of information and data for foreign and domestic intelligence and counterintelligence purposes.
The details
The PT-100 functions as a cryptographic subsystem that secures data transmissions within the Eagle Secure Network Radio. It relies on the Wolverine Cryptographic Module to manage encryption processes, ensuring that the system meets stringent security doctrine requirements. This subsystem is slated to serve as an upgrade for the Integrated Fires Mission Command Huntsman LX4-SAB radio, which facilitates communications for tactical defense operations.
Timeline
September 29, 2026: Rajant announced that the NSA had granted certification for the PT-100.
The Tech Race
The development follows strategic mandates set by the Counter-Unmanned Aircraft Systems Program Office to address secure data needs in modern tactical warfare. It marks a shift toward standardized, interoperable encryption for hardware used across U.S. and allied defense networks.
The certification authorizes the PT-100 for deployment within the Armed Forces Counter-Rocket, Artillery and Mortar Warning system. Future upgrades to the Integrated Fires Mission Command Huntsman LX4-SAB radio will utilize this technology once implemented by defense authorities.
The takeaway
The NSA certification confirms the hardware is ready for integration into existing secret-level tactical networks. Stakeholders should monitor forthcoming defense procurement updates regarding the phased replacement of the Huntsman LX4-SAB radio fleet.
