Case Study: Rebellion Defense strengthens email and Google Drive security with Material Security

Adaptable email defenses at Rebellion Defense

Rebellion Defense, a high-growth technology company serving government security needs, needed stronger protection for its Google Workspace environment as it faced sophisticated phishing, VIP impersonation, and data exfiltration risks. Working with Material Security, the team sought better visibility and control over email and Google Drive to protect sensitive IP and reduce reliance on manual user reporting.

Material Security implemented layered email defenses, VIP impersonation remediation, DLP for email and Google Drive, identity protection, and posture management, with custom detections and automated alerts flowing into Slack. The results included nearly all malicious emails being flagged by Material before users saw them, faster incident response, automatic deletion of high-confidence VIP impersonation emails, and significantly improved control over external file sharing and sensitive data exposure.
