Best SSO solution for a +50 company

I'm collecting opinions on the best SSO solution for a mid-sized company that only has a few DevOps specialists.

I have created a (very) preliminary list of solutions. I want to test them for ease of integration, costs, ability to integrate with other services ect. These are:

  • Azure Idap
  • KeyCloak
  • AWS Cognito
  • Azure Active Directory
  • AWS SSO

We definitely want to integrate with Github, Gmail, Vault, AWS and Graylog.
