Best For
Multi-tenant SaaS, token delegation for agents, fine-grained authorization at scale
Enterprise on-prem identity; legacy system integration; organizations standardized on Red Hat / Java stacks
Limitations
Vendor lock-in on cloud plan; self-hosted (Private Cloud) is enterprise-tier only; dynamic client registration for MCP requires Enterprise plan to secure against abuse
No agent SDK, no FGA, no human-in-the-loop; UI and developer experience are dated; heavy Java-based deployment
