Product Overview

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, and Deep CDR™ (Content Disarm & Reconstruction) against file-based threats. With multi-layered, proactive protection, email security goes beyond signature-based detection with advanced technologies against evolving threats. Designed for seamless integration, the solution deploys rapidly without disrupting mail flow.

Features

Metascan™: Advanced Threat & Zero-day Malware Prevention

• Detects known and unknown threats with up to 99.2% efficacy using 5 to 17 leading anti-malware engines running in parallel. MetaScan™ increases detection rates, reduces false negatives, and shortens time-to-detection for zero-day malware.

Engines

The following AV engines are available in MetaDefender™ Cloud Email Security:

Deep CDR™: Protection Against File-Based Attacks

• Neutralize file-borne threats by removing active content, scripts, macros, and embedded objects from documents and media files. This proactive sanitization ensures only safe, usable files reach the inbox—without disrupting business workflows.

Benefits

MetaDefender™ Cloud Email Security bolsters Microsoft 365's security posture with advanced threat and zero-day malware prevention, providing robust, multi-layered security complementing Microsoft 365’s native protection. OPSWAT’s exclusive MetaScan™ and Deep CDR™ technologies detect and neutralize known, unknown, and zero-day threats, reducing the risk of malware, ransomware, and file-based exploits.

• Eliminates hidden, file-based threats before they reach users: Disarm malicious content within attachments and embedded objects in real-time, preventing weaponized files from reaching inboxes, even if they’re unknown to antivirus engines, for true proactive protection.
• Simplifies deployment with zero disruption to mail flow: Integrates seamlessly with Microsoft 365, without requiring MX record changes or architectural reconfiguration, ensuring rapid setup and uninterrupted email delivery.
• Enhances compliance and audit readiness with detailed reporting: Provides centralized visibility and granular logging of emails, attachments, threat events, and policy action, helping organizations meet cybersecurity, regulatory, and internal compliance requirements.
• Reduces SOC workload with fewer false positives and remediations: By combining high-accuracy detection and sanitization, the solution minimizes alert fatigue, accelerates investigation time, and allows SOC teams to focus on real threats rather than sifting through false alarms.
• Backed by OPSWAT's legacy of successfully protecting critical infrastructure: Built by a cybersecurity leader and trusted by over 1,800 global critical infrastructure organizations, MetaDefender™ Cloud Email Security brings proven, industrial-grade threat prevention to enterprise email environments.
