More orgs need to leverage keycloak more. I know java give some people shivers here, but it's an excellent setup to help accelerate your authentication needs, especially in the B2B space.

I'm not big on microservices unless your org is scaled people wise and need to decouple your team, but I'm happy to outsource to Keycloak as an auth focused service.

Cool integration in the k8's space.

https://fusionauth.io/ is also a more modern alternative.

More modern? Keycloak is only five or six years old!

Keycloak is open source, this one isn't.

How is keycloak compared to Pomerium for example?

Keycloak is an identity provider. It's an Oauth2/OpenIDConnect authorization server. Pomerium looks to be some kind of proxy to enforce authorization (in OAuth2 jargon, it would be a resource server).

Succinctly: Keycloak issues security tokens, Pomerium (I think) accepts security tokens.
