MetaDefender Cloud Email Security™ is an advanced solution that bolsters Microsoft 365’s native email defenses with industry-leading threat prevention. It is purpose-built to detect and neutralize malware, zero-day exploits, and embedded file-based threats before they reach the inbox.

This solution is powered by OPSWAT’s Metascan™ Multiscanning, adding more AV (antivirus) engines, MetaDefender Aether Sandbox for advanced dynamic threat analysis, and Deep CDR™ (Content Disarm & Reconstruction) against file-based threats. By combining signature-based detection, behavioral sandboxing, and proactive content sanitization, email security extends beyond traditional defenses to identify and neutralize both known and zero-day threats. With multi-layered, proactive protection and advanced technologies designed to combat evolving attack techniques, the solution deploys rapidly and integrates seamlessly without disrupting mail flow.
