Based on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise security teams deploying AI agents across Microsoft environments need Witness Protect for its bidirectional runtime defense that actually blocks prompt injection and jailbreak attempts before they execute, not after telemetry arrives. The multi-step jailbreak detection and network-level visibility of AI interactions map directly to NIST PR.PS and DE.CM, covering both prevention and continuous monitoring where most guardrails only handle one. Skip this if your AI use cases are limited to read-only chatbots or if you lack the integration footprint to justify a dedicated firewall layer.
