nShield 5c

Entrust nShield 5c HSMs

nShield 5c HSMs are security appliances that deliver cryptographic services to applications across the network, in the cloud, and in hybrid environments. The hardened, tamper-resistant, FIPS 140-3 level 3 certified (expected June 2023) platforms perform such functions as encryption, digital signing, and key generation and protection. With their comprehensive capabilities, flexible hybrid deployments, quantum crypto-agility, and 100% compatibility with existing nShield HSM deployments and APIs, these HSMs can support an extensive range of applications, including certificate authorities, code signing, and more.

High-performance, scalable HSMs that save you time and money

The new nShield 5c models offer enterprises a reduction in total cost of ownership, eliminating costly repeat trips to the data center and reducing the overhead of managing and configuring HSM estates. Features include:

  • Centralized, remote visualization and management console supporting HSM administration and Security World management
  • A serial console supporting provider/tenant deployment models through strong role separation, delineating tasks such as changing network settings from controlling cryptographic actions
  • Remote presentation of physical tokens to authorize administration tasks and cryptographic key usage
  • Seamless interoperation with all other variants and versions of the nShield HSM family

These features reduce the demands on highly specialized and trained resources, provide enterprises with efficiency gains, and ensure control over the HSMs resides in the hands of the security professionals.
