Where are your private keys?

Enterprises with large IT environments must secure and manage access to hundreds of thousands, or even millions, of private keys for a variety of use cases: code signing, SSH, document signing, S/MIME, and TLS, to name a few.

All too often, private keys are simply left in software across hundreds of different servers and end-user workstations. Many of these keys have no visibility and are unauditable, while others are no longer in use and should be deleted altogether. This scenario presents major security risks and compliance challenges.

Superior security. No trade-offs.

Enterprises that keep their private keys secured in HSMs or key managers have often been forced to accept diminished performance in exchange for security. With GaraSign, this trade-off is no longer necessary. You get the best of both worlds, plus a host of client integrations and easy implementation.


With GaraSign, your private keys remain secured in HSMs while signing clients are restricted to proxied key access.


A client-side hashing architecture speeds up cryptographic operations for all public/private key use cases.


GaraSign comes with a host of native client integrations, including Microsoft, Apple, Java, GPG, rpm, PKCS#11, npm, and more.

GaraSign works seamlessly on every end-user's workstation without needing to install new software.

One powerful platform for all use cases.
