IPS-250X HAIPE Encryptor (CHVP)

Secure connections in high-risk environments

The Viasat IPS-250X is a rugged, low-size, weight, and power (SWaP) National Security Agency (NSA)-certified high-speed Internet Protocol (IP) network encryptor for Secret and below communications. It allows for secure IP connections with U.S. warfighters and government agencies without the deployment limitations, expensive logistics, and lifecycle costs associated with Controlled Cryptographic Items (CCI).

The IPS-250X is an Inline Network Encryptor (INE) that complies with NSA Cryptographic High Value Product (CHVP) Policy Committee on National Security Systems Instruction (CNSSI)_4031 for Non-CCI handling of HAIPE Suite B devices.


Supporting the secure exchange of classified information up to the Secret level, the IPS-250X is appropriate for government agencies such as the Federal Bureau of Investigation (FBI), Department of Homeland Security (DHS), and first responders with users in their networks who may not have COMSEC accounts or want to minimize COMSEC logistics.


Loaded with HAIPE Interoperability Specification Compliant Suite B cryptography and packaged in a low-size, weight, and power (SWaP) rugged form factor, the IPS-250X is ideal for high-risk and unmanned environments. With an optional remote front panel, aircraft operators can interface with the IPS-250X via cable, providing control access even if the stowed crypto is not physically within reach.
