SafeZone FIPS Cryptographic Module

FIPS 140-2 certificate #4588 · Rambus Inc. · data as of 2026-09-03

SafeZone FIPS Cryptographic Module, from Rambus Inc., holds FIPS 140-2 certificate #4588 at overall level 1. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its validation history, algorithm certificates and security policy, drawn from the NIST CMVP entry.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement.
Caveat: When operated in FIPS mode. The module generates cryptographic keys whose strengths are modified by available entropy
