eMudhra CERTInext vs SEALSQ VaultIC408: Side-by-Side Comparison (2026)

SEALSQ VaultIC408

Enterprise and mid-market teams embedding IoT devices in mission-critical infrastructure should evaluate VaultIC408 for its tamper-resistant key generation and storage, which eliminates the attack surface of software-only device identity management. NIST FIPS 140-3 Level 3 certification with 572-bit elliptic curve support and true random number generation (SP 800-90A/B compliant) means cryptographic material stays isolated from compromised host firmware, addressing the PR.AA and PR.DS gaps that plague generic IoT platforms. Skip this if you need post-quantum algorithms or are still in the assessment phase; VaultIC408 is a hardware commitment for organizations that have already decided cryptographic isolation is non-negotiable.
