Varonis Microsoft 365 Security

Varonis Microsoft 365 Security is a specialized cloud data protection and security posture management solution engineered to safeguard corporate data across Microsoft 365 services—including SharePoint Online, OneDrive, Microsoft Teams, and Exchange Online. By combining automated sensitive data classification, granular permissions mapping, and real-time behavioral threat detection, it prevents unauthorized exposure, accidental data oversharing, and external collaboration risks across enterprise productivity suites.

The platform connects agentlessly via Microsoft Graph and cloud APIs, scanning files, emails, chat repositories, and configuration settings across enterprise Microsoft 365 tenants. It integrates natively with Microsoft Entra ID, Microsoft Information Protection (MIP), and enterprise SIEM/SOAR platforms to correlate user authentication events with cloud file interactions. Key implementation use cases include automatically discovering and removing public and company-wide sharing links, eliminating stale external guest user permissions, detecting compromised user accounts attempting data exfiltration, and preparing tenant data repositories for secure Microsoft 365 Copilot adoption.

Featuring automated, intelligent remediation capabilities, Varonis Microsoft 365 Security locks down exposed sensitive data without breaking collaborative workflows for end users. Security operations teams benefit from real-time threat alerts that detect abnormal file downloading, mass deletions, and suspicious mailbox forwarding rules. The platform provides continuous visibility into cloud collaboration risks, ensures strict regulatory compliance, and delivers dependable defense for enterprise Microsoft 365 environments.
