X4i Hardware Security Module (HSM)
X4i Hardware Security Module (HSM), from Pitney Bowes, Inc., holds FIPS 140-2 certificate #4225 at overall level 3. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its algorithm certificates, its validation history, and the list moves this tracker has observed, which NIST does not date.
Caveat: When operated in FIPS Mode. No assurance of the minimum strength of generated keys.
