SEALSQ Corp announced that its VaultIC408 secure element platform, version 1.2.4, has been validated to FIPS 140‑3 Level 3 by the U.S. National Institute of Standards and Technology. The certification, numbered 5463, was issued on August 5, 2026 and remains active until August 4, 2031.
Testing was carried out by Penumbra Security, Inc., and confirmed that the module meets Level 3 requirements for cryptographic algorithms, authentication, secure key management, physical security, self‑testing and tamper resistance. The device supports NIST‑approved capabilities such as AES, RSA, ECDSA, SHA‑2, HMAC, elliptic‑curve key agreement, key‑derivation functions and deterministic random‑bit generation.
SEALSQ positions the VaultIC408 for use in government, defence, critical‑infrastructure, industrial IoT, secure manufacturing and connected‑device identity applications where hardware‑based security is mandatory.
The company, which develops semiconductors, public‑key‑infrastructure and post‑quantum technology products, highlighted the validation as a milestone for its security portfolio. CEO Carlos Moreira noted that the certification underscores the module’s suitability for high‑assurance environments.
