Signing wherever you need it

Server-side signing

SignServer Hardware Appliance enables centralized signing for full control of all your digital signature use cases.

Turn-key solution

Easy and fast deployment and updates with a stable package that includes the complete software and hardware stack - not only the signature application.

HSM included

PrimeKey always recommends using an HSM with your digital signing solution. That is why SignServer Hardware Appliance comes with an integrated FIPS-certified HSM, for easy installation and maintenance. 


Features of SignServer Hardware Appliance

SignServer Hardware Appliance includes SignServer Enterprise and offers a centralized, and thus controlled electronic and digital signing system for documents, code, timestamping and travel documents. With its integrated HSM, it is the most efficient way to implement, deploy and maintain an on-premises enterprise digital signature service over time. 


Complete technology stack

SignServer Hardware Appliance is delivered as a rack-mounted hardware appliance and comes with a fully tested and complete software and hardware technology stack. 



Easy to maintain 

Easy and effective management is the key to a secure and reliable digital signature service deployment. Updates and upgrades are delivered as complete and tested software packages for smooth maintenance. Backup and restore routines are robust and simplified to reduce manual errors. 


FIPS-certified HSM

An integrated FIPS 140-2 Level 3-certified HSM brings enterprise-grade security, keeping all your signing keys secure. With SignServer Hardware Appliance, it is easy to move away from managing a myriad of signature solutions all over the organization. 


Flexible for your use cases

PrimeKey understands that organizations have different needs and business requirements - and that things evolve over time. We therefore offer the SignServer Hardware Appliance in models supporting your signature use cases and need for HSM capacity. This gives you the possibility to scale and add more use cases as the demand from your business changes.
