Actifile Data Leakage Prevention vs Microsoft Purview Data Loss Prevention: 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 Data Loss Prevention

Organizations with Microsoft 365-heavy workflows should pick Microsoft Purview Data Loss Prevention because it requires zero configuration for cloud workloads and catches sensitive data movement across Teams, SharePoint, and OneDrive without additional agents or console sprawl. The integration with Microsoft 365 Copilot means you're protecting data at the point where employees are actually working, not just at the perimeter. Skip this if your critical data lives outside Microsoft's ecosystem or you need network-layer DLP that works equally well on non-Microsoft SaaS applications; Purview's strength is depth within one vendor's stack, not breadth across your entire software inventory.
