Keep Private Keys Secure, Without Limiting Performance

With GaraSign, you can keep all of your company's private keys secured in HSMs or key managers at all times, without reducing the speed of cryptographic operations. GaraSign is compatible with code signing, SSH, document signing, TLS, S/MIME, and more.

Are all of your keys secure?

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.

With GaraSign, you get the best of both worlds: the superior security of HSMs combined with truly outstanding performance, plus a host of client integrations to simplify deployment.


With GaraSign, your private keys remain secured in an HSM 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.
