FIPS 140-3 is not a security guarantee, and auditors know it

FIPS 140-3 certification validates only that a cryptographic module implements approved algorithms correctly and meets specific design requirements—not that the overall product, its operation, or key management are secure. The certificate's narrow scope is often misunderstood by procurement teams, leading to a persistent gap between what FIPS actually guarantees and what organizations believe it covers, with most deployed systems drifting from their validated configurations within months.
