BitLocker Dump Filter

FIPS 140-2 certificate #4688 · Microsoft Corporation · data as of 2026-10-09

BitLocker Dump Filter, from Microsoft Corporation, holds FIPS 140-2 certificate #4688 at overall level 1. 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.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement. Observed moving to historical on 2026-09-22. It was one of the last FIPS 140-2 certificates, all moved at the 140-2 sunset on 2026-09-21.
Caveat: When operated in FIPS mode with the module Code Integrity under Cert. #4602 operating in FIPS mode or Secure Kernel Code Integrity under Cert. #4640 operating in FIPS mode

Module description

Quoted from the NIST CMVP entry for this certificate.

The BitLocker® Dump Filter (dumpfve.sys) is the full volume encryption filter that resides in the system dump stack. Whenever the dump stack is called (in the event of a system crash), this filter ensures that all data is encrypted before it gets written to the disk as a dump file.
