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 (Coordination Stage).


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.

nShield Monitor

nShield Monitor is a monitoring platform that provides 24x7 visibility into the status of nShield HSMs. With this solution, security teams can efficiently inspect HSMs and find out immediately if any potential security, configuration or utilization issue may compromise their mission-critical infrastructure.

Remote Administration Kits

nShield Remote Administration lets operators manage distributed nShield HSMs – including adding applications, upgrading firmware, checking status, re-booting and more – from their office locations, reducing travel and saving money. Remote Administration Kits contain the hardware and software needed to set up and use the tool.


CodeSafe is a powerful, secure environment that lets you execute applications within the secure boundaries of nShield HSMs. Sample applications include digital meters, authentication agents, digital signature agents and custom encryption processes. CodeSafe is available with FIPS Level 3 certified network attached and PCIe nShield HSMs


CipherTools is a set of tutorials, reference documentation, sample programs and additional libraries. With this toolkit, developers can take full advantage of the advanced integration capabilities of nShield HSMs. In addition to offering support for standard APIs, the toolkit enables you to run custom applications with nShield HSMs. CipherTools is included free of charge in the standard Security World software ISO/DVD.

KCDSA Activation

With the KCDSA activation license, you can use the Korean Certificate-based Digital Signature Algorithm (KCSDA) as well as HAS-160, SEED, and ARIA algorithms on nShield HSMs.

Smart Card Reader Rackmount

For organizations deploying one or more nShield 5s modules in a 19" rack, the optional nShield smart card reader rackmount provides a practical and clean solution for attaching card readers in the data center. The rackmount is 1U in height and can be equipped with up to four smart card readers, which come standard with nShield 5s cards. Each unit is packaged with three blanking plates to cover any unused slots.
