CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise security teams deploying Windows Copilot and Office 365 need Witness AI Product because it maps AI usage at the network level before it becomes a governance nightmare. Coverage across ID.AM, PR.DS, and DE.CM means you're getting asset discovery, data protection, and continuous monitoring specifically for AI,not bolted-on afterthoughts in a general platform. Skip this if your AI risk appetite is still theoretical or your workforce hasn't standardized on Microsoft AI tools yet.
Enterprise and mid-market security teams building or deploying large language models need Zscaler AI-SPM because it's the only tool that maps AI risks to actual business impact rather than just flagging misconfigurations. The platform covers the full AI supply chain from training data access control through prompt injection detection and LLM output monitoring, with explicit compliance mappings to NIST AI RMF and EU AI Act requirements that auditors actually ask for. Skip this if your organization treats AI security as a footnote to your existing cloud posture program; AI-SPM assumes AI is now a primary business system worth dedicated governance.
