Janssen
The Janssen Project tackles the authentication and authorization aspects of cloud security. The project's components include various implementations of the OAuth, OpenID Connect, and FIDO standards.
Janssen is a Linux Foundation project and, as such, is governed according to the foundation's charter. Ultimately, the project's goals include coalescing a community and fostering an ecosystem rather than simply putting a product or collection of technologies into the market.
But more than simply an authorization and authentication server, Janssen provides the components for a scalable, centralized authentication and authorization service. While the project acknowledges that a number of commercial (and even other open source) authentication systems are available, Janssen is intended to be highly scalable, highly available, and highly flexible, with special attention paid to organizations with huge volumes of concurrent user loads or large fleets of Internet of Things (IoT) devices that need to be authenticated and authorized onto the network.
