Compliance and deployment
FIPS 140
FIPS 140 is the US government standard for validating cryptographic modules, with security levels from 1 to 4 covering tamper evidence, tamper resistance, and environmental protections. FIPS 140-2 Level 3 and FIPS 140-3 Level 3 are the benchmarks banks require for custody HSMs.
Reading FIPS levels in custody due diligence
Level 3 adds physical tamper resistance and identity-based authentication; Level 4 adds environmental attack protection. The certificate must cover the module actually deployed and the algorithms actually used, a detail worth verifying in vendor claims.
Taurus-PROTECT uses FIPS 140-2 Level 3 HSMs as its root of trust, with FIPS 140-3 Level 3 and 4 hardware in air-gapped cold storage deployments, and FIPS-certified encrypted USB media in the physical air gap transfer process.
