Acronis DeviceLock DLP vs ProLion Storage Security: Side-by-Side Comparison (2026)

Short answer

SMB and mid-market teams with virtualized workforces will find the most value in Acronis DeviceLock DLP, which handles endpoint DLP across RDS, Citrix, and VMware environments without requiring separate agents per platform. The combination of USB blocking, application-level controls, and native Active Directory integration means enforcement works immediately after Group Policy deployment. Skip this if your organization relies heavily on cloud-native infrastructure or needs behavioral analytics; DeviceLock's strength is prevention through rigid policy, not detection of anomalous user activity, which leaves the ID.RA risk assessment piece incomplete without external SIEM correlation. SMB and mid-market teams with on-premises storage infrastructure need ProLion Storage Security for its automated response to ransomware; the moment it detects suspicious file access patterns, it blocks the offending user without waiting for human intervention, which cuts recovery time from hours to minutes. The platform covers the full incident lifecycle from continuous monitoring through granular file restoration, with 24/7 vendor support included as standard. Skip this if your storage lives entirely in cloud object services or if you need deep SIEM integration beyond basic log forwarding; ProLion's strength is protecting NAS and SAN environments where traditional access controls have already failed.
