Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Microsoft Purview Information Protection
Mid-market and enterprise teams already deep in Microsoft 365 will find their fastest path to data classification here because Purview classifies and labels at scale without ripping out existing infrastructure. The AI-powered classifiers work across SharePoint, OneDrive, Exchange, and Teams simultaneously, and the exact data match capability catches structured data like credit cards and social security numbers that pattern-matching alone misses. Skip this if your data lives primarily outside Microsoft environments or if you need detection and response for data exfiltration; Purview excels at ID.AM asset discovery and PR.DS labeling but leaves incident investigation to other tools.
Mid-market and enterprise teams drowning in unstructured data sprawl should start here; ProLion DataAnalyzer maps permission risk and ransomware indicators across storage faster than manual audits, which matters when you're trying to actually shrink your attack surface instead of just inventorying it. The tool covers three critical NIST CSF 2.0 areas,asset management, data security, and continuous monitoring,which means it handles the full lifecycle from discovery through permission drift detection, not just snapshots. Skip this if you need cloud-native storage classification or expect deep SIEM integration; ProLion is on-premises focused and assumes Active Directory as your identity backbone.
