Make PKI simpler and safer

Would you like to predict costs and save resources while increasing the quality and minimizing the risks of your PKI project? Get a simplified installation and maintenance of your PKI solution with PrimeKey PKI Appliance. Our turnkey PKI Appliance is the best choice for most medium to large deployments — suitable even for managed services and Internet of Things (IoT).

Our packaged PKI-in-a-box concept offers the easiest and most secure way to deploy an enterprise PKI system without the hassles of elaborate installation and integration procedures.

By delivering strongly on security, performance and simplified maintenance, PrimeKey PKI Appliance empowers your own security team to focus on aspects more directly beneficial to your business — the core certificate lifecycle, code and documents themselves.

PrimeKey PKI Appliance has a fixed price list and enables you to save months of work and expenses. The Appliance is also particularly useful if you are looking for additional hardware to go with your overall PKI solution, or if you don’t have your own PKI department.

And a single instance of the Appliance enables you to govern multiple CAs, reducing any need for several, dedicated hardware units.

Manufactured from our comprehensive experience and expertise, PrimeKey PKI Appliance succeeds in making your EJBCA PKI solution more robust, cost efficient and more scalable.
