Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
1Security Microsoft Copilot Security
Security teams deploying Microsoft Copilot across M365 need visibility into what data the AI can actually access before oversharing becomes a compliance liability, and 1Security Microsoft Copilot Security is built explicitly for that pre- and post-deployment control. The tool maps Copilot's permissions through Microsoft Graph, flags excessive access across SharePoint and OneDrive, and automates remediation of misconfigurations, addressing the asset management and data security gaps that most M365 tenants haven't solved yet. Skip this if your organization hasn't standardized on Microsoft's ecosystem or if you're looking for a Copilot governance tool that also covers other generative AI platforms; 1Security is Microsoft-only.
Sentra Accurate Data Discovery & Classification
Mid-market and enterprise teams buried under shadow data across multiple clouds need Sentra Accurate Data Discovery & Classification because its proprietary LLM classifies unstructured data with >95% accuracy, eliminating the false positives that tank adoption of weaker rule-based classifiers. The agentless architecture works across AWS, Azure, GCP, and Snowflake without slowing cloud operations, and continuous monitoring actually catches exfiltration attempts instead of just cataloging what you already know exists. Skip this if your primary need is access governance; Sentra's strength is finding and classifying hidden data, not orchestrating least-privilege controls across identity systems.
