nShield 5s

Entrust nShield 5s HSMs

nShield 5s HSMs are PCIe cards that perform encryption, digital signing, and key generation for an extensive range of commercial and custom-built applications, including certificate authorities, code signing, and more. With their comprehensive capabilities and quantum crypto-agility, they are 100% compatible with existing nShield HSM deployments and APIs, and they are highly secure, with FIPS 140-3 Level 3 certification*.

Models

The nShield 5s HSM series includes the new high-performance nShield 5s High, which offers superior asymmetric and symmetric performance and best-in-class elliptic curve cryptography (ECC) transaction rates.
