Cisco 4451-X Integrated Services Router (ISR) (with PVDM4-32, PVDM4-64, PVDM4-128 and PVDM4-256)

FIPS 140-2 certificate #2278 · Cisco Systems, Inc. · data as of 2026-09-03

Cisco 4451-X Integrated Services Router (ISR) (with PVDM4-32, PVDM4-64, PVDM4-128 and PVDM4-256), from Cisco Systems, Inc., holds FIPS 140-2 certificate #2278 at overall level 2. 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 with tamper evident labels and security devices installed as indicated in the Security Policy
