Actifile Data Leakage Prevention vs Microsoft Purview: Side-by-Side Comparison (2026)

Actifile Data Leakage Prevention

Mid-market and enterprise security teams drowning in shadow IT data sprawl should start with Actifile Data Leakage Prevention because its automated discovery requires zero policy tuning to find what you actually have. The 24/7 background monitoring and one-click encryption hit NIST PR.DS and ID.AM without forcing endpoint agents or performance hits, which matters when you're understaffed. Skip this if you need forensic-grade incident response or cross-cloud data lineage mapping; Actifile prioritizes discovery and containment over investigative depth.

Microsoft Purview

Enterprise and mid-market teams already invested in Microsoft 365 should buy Microsoft Purview for data classification and DLP enforcement without the integration tax that standalone tools carry. It covers NIST PR.DS and DE.CM simultaneously, giving you labeling, discovery, and policy enforcement across email, cloud apps, and devices from one console. Skip this if your organization runs on Google Workspace or has minimal Microsoft infrastructure; the product assumes M365 as your data backbone, and retrofitting it elsewhere creates friction that negates the convenience argument.
