Verify identity and device
Strong authentication should be paired with device signals such as management state, security updates, and key protection. Either signal alone leaves important gaps.

Make decisions observable
Log policy decisions, denied requests, privilege changes, and sensitive data access. Teams need enough context to reconstruct why access was allowed without collecting unrelated personal data.
