The short version

  • Only Keycloak has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fortinet FortiGate security services are sold as separate FortiGuard subscription bundles, so ATP, UTP and ENT determine which protections are actually active; Keycloak requires self-hosted deployment and operational expertise to install, configure and maintain
  • Prices and features above were last checked on 30 August 2026.
