    A reverse proxy that provides authentication with Google, Azure, OpenID Connect and many more identity providers.

  4. Pomerium

    Pomerium is an identity and context-aware reverse proxy for zero-trust access to web applications and services.

    Just want to drop https://www.pomerium.com/ here. We use it at our company with ~1500 people with many apps behind the proxy. It also supports JWT for the backend, so you can integrate your apps easily without having to worry about the OAuth flow and also your apps are protected from random internet attacks.
