Acronis DeviceLock DLP vs Nightfall Data Loss Prevention: Side-by-Side Comparison (2026)

Acronis DeviceLock DLP

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.

Nightfall Data Loss Prevention

Mid-market and enterprise teams drowning in SaaS sprawl need Nightfall Data Loss Prevention because it actually catches data leaks in ChatGPT, Slack, and Google Workspace instead of pretending they don't exist. The platform covers ID.AM and PR.DS across cloud apps and endpoints with real-time blocking, plus its Nyx agent automates incident investigation so your team isn't manually triaging alerts at midnight. Skip this if you're primarily concerned with on-premises data centers or need deep DLP integration into legacy enterprise applications; Nightfall's strength is modern, cloud-first environments where traditional perimeter controls don't apply.
