GaraSign: A Secure Platform for Cryptographic Operations

You may not realize it, but private keys enable many of the day-to-day operations in your enterprise IT environment. Code signing, SSH, TLS, and TDE, to name a few, all rely on public-private key pairs. Consequently, it’s vital to maximize security around private keys without limiting access to them or inhibiting the performance of business processes. 

GaraSign is the solution that provides this balance. It’s a platform for cryptographic operations that combines superior security with unparalleled performance.

Securing your private keys is a mission-critical task.

What about performance?

Hardware security modules (HSMs) offer excellent security for private keys and should be employed by all companies that take cybersecurity seriously.

However, it can be challenging to develop custom integrations with HSMs in-house, as it isn’t a core competency of most enterprises using HSMs. Poorly-designed integrations often cause performance bottlenecks, making it seem as though speed is being sacrificed for the sake of security.  

Inefficient Integrations

HSMs expose limited interfaces, making it difficult to build custom integrations to the tools and platforms you're using.

Potential Vulnerabilities

Developing cryptographic integrations to an HSM is a difficult project and can introduce major vulnerabilities if not done properly.

Poor Performance

When integrations are incorrectly architected, cryptographic operations can take significantly more time than necessary.

GaraSign gives you the best of both worlds: maximum security and outstanding performance, plus all the integrations you need.

Proxied Key Access For Signing Clients

GaraSign sits on a fully customer-managed server between your company’s HSMs and the signing clients, restricting those signing clients to proxied key access.

The result is that private key material remains in HSMs at all times, providing maximum security, while team members can still gain access to all the private keys they need to create digital signatures.

Multi-Factor Authentication

With GaraSign, it is trivial to transparently layer-in multi-factor authentication and/or device authentication to maximize the security around your private keys.

Since signing clients are restricted to proxy key access, GaraSign can easily introduce MFA and device authentication requirements for private key access, without you needing to reconfigure servers or develop custom MFA solutions.

A Client-Side Hashing Architecture

GaraSign is built with a client-side hashing architecture. Signing clients hash the data they need to sign before sending it over the network to create the signature.

This hash signing architecture limits the amount of data being transmitted over the enterprise network, so digital signature processes like code signing, SSH, document signing, and more, all remain fast and efficient.

Integrations To All The Tools You Use

GaraSign comes with a host of native client integrations, making it easy to drop GaraSign directly into your environment without needing to develop custom integrations in-house.

One Platform For All Private Key Use Cases

GaraSign is compatible with all public-private key use cases so you can leverage your HSMs for the protection of all private keys, helping to maximize ROI on your company’s HSM purchases.
