GaraSign: A Secure Platform for Cryptographic Operations

You may not realize it, but public key cryptography enables many of the day-to-day operations in your 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 slowing the pace 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 Access To HSM-Secured Keys

GaraSign is deployed on customer-managed infrastructure between the HSM and the signing clients, restricting those signing clients to proxied key access.

The result is that private keys remain secured and non-exportable in HSMs at all times, providing maximum security, while end-users can still gain access to all the private keys they need to perform cryptographic operations.

Advanced Security Features

Since signing clients are restricted to proxied key access, GaraSign can transparently integrate into existing processes to provide advanced security features, including multi-factor authentication, device authentication, approval workflows, IP address whitelisting, notifications, and more. These additional security features can be set individually for each private key stored in the HSM.

High Performance With Hash Signing

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

This client-side hashing 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 deploy GaraSign directly into your IT environment without needing to develop custom integrations.
