Choose Hawcx when
Entra ID stays your directory, and every agent tool call must be checked before it runs, carry proof of who delegated it, and get a grant that works once.
Hawcx vs 
Microsoft Entra Agent ID for AI agent authentication
Both give AI agents their own identities, tied to people in your directory. Hawcx works with Entra ID and adds three things at every tool call: a policy check before it runs, proof of who delegated it, and a grant that works once.
