Varonis for Microsoft 365

Protect your critical Microsoft 365 data with least privilege automation, data-centric UEBA, and world-class data classification. 

  • Agentless
  • Automated
  • Azure Marketplace

Partner with the leader in data security.

Forrester’s report states "Varonis is a top choice for organizations prioritizing deep data visibility, classification capabilities, and automated remediation for data access."

Securely deploy Microsoft 365 Copilot.

Copilot scours your environment, searching through all the sensitive data that a user can access, which is often far too much. Varonis helps you prepare for a safe Copilot rollout by limiting each user's access and detecting abnormal use of AI tools that pose a security threat.

Find and classify sensitive data across Microsoft 365.  

Automatically and accurately classify sensitive data shared across your environment. Varonis looks inside every file and folder to find sensitive information, and show you exactly where it lives and who has access to it — all in an easy-to-read file tree.

Apply accurate and actionable MPIP labels. 

Varonis fully integrates with Microsoft Purview to enhance Microsoft's native classification in E3 and E5.  Create granular policies to fit your needs, automatically fix manual gaps, and re-label files as your data changes — making downstream DLP controls more effective. 


Enforce least privilege across Microsoft 365.

Effortlessly eliminate data exposure from shared links and excessive permissions. Varonis makes intelligent decisions about who needs access to data and who doesn’t and then automatically remediates risky permissions at scale.
