Security First and High Performance

Sleep easy, knowing that Ory Hydra is designed to reduce security incidents and scales as required. Ory Hydra serves tokens to millions of users weekly and just works.

At Sainsbury’s Tech, we needed a feature-complete OAuth provider which can operate securely at scale and Ory Hydra fit the bill perfectly.

Paul Harman // Engineering Manager, Sainsbury’s Tech

We rely on Ory to be our OAuth provider and it fits perfectly into our infrastructure, is hardened, and aligns with our principles. Ory is a great fit for us.

Benjamin Kristensen // Senior Software Engineer, Enode

At Discogs we use Ory to handle authentication and authorization for over 8 million music enthusiasts across our applications. It allows us to focus on building the largest music database and marketplace, rather than reinvent the wheel.
