Proofpoint DSPM Vs. Varonis For Microsoft 365 And Copilot: Better Accuracy, Lower Cost, Faster Time To Value
Proofpoint, Friday, February 6th, 2026
As organizations adopt Microsoft Copilot and other generative AI (GenAI) tools, data is spreading faster than ever. Using GenAI, sensitive data can be rapidly accessed, summarized, transformed, and shared.
But while GenAI tools unlock productivity, they also expose serious gaps in legacy data security platforms-especially those designed for on-premises environments.
These gaps are particularly serious for organizations still using Varonis' on-premises platform. That product reaches end-of-life on December 31, 2026. Customers must move to Varonis SaaS, re-scan all Microsoft 365 and on-premises data and take on higher costs. Many make this move without gaining clearer visibility of data exposure from Copilot or other AI tools.
Because of this, many organizations are replacing Varonis with Proofpoint Data Security Posture Management (DSPM). Proofpoint DSPM is a cloud-native solution built to secure Microsoft 365, Copilot and AI-ready data. It does this with greater accuracy, lower overhead, and faster return on investment (ROI).
