MetaDefender Email Gateway Security

Deliver trust to your inbox

Most malware is initiated through email. Links and attachments that appear safe can contain malicious content. Once accessed, malware replicates and spreads across the network. 

MetaDefender Email Gateway Security examines every email and attachment, scanning and addressing malicious content, before it’s delivered. 

Advanced threats can bypass many malware detection applications used by email security solutions today. 

MetaDefender Email Gateway Security evaluates inbound and outbound emails, reconstructs suspicious attachments, and redacts sensitive content—while maintaining consistent email delivery flow. Hyperlinks to unsafe URLs are also replaced with plain text to prevent user misbehavior. 


Neutralize Malicious Emails

Our Deep CDR technology, also known as Deep Content Disarm and Reconstruction, ‘disarms’ each email body & attachment by removing all potentially malicious content. The reconstructed, fully usable email attachments are then delivered to the user’s mailbox for safe use.

Detect More Email Malware

By multiscanning emails with 35+ anti-malware engines using signatures, heuristics and machine learning, MetaDefender Email Gateway Security significantly improves detection of known and unknown threats and provides the earliest protection against malware outbreaks.

Protect PII

MetaDefender Email Gateway Security offers proactive data loss prevention (Proactive DLP) to prevent emails with sensitive content leaving or entering the organization by content-checking the email body and attachments for credit card numbers, social security numbers, and content that matches custom regular expressions.

Uncover & Defuse Phishing Links

MetaDefender Email Gateway Security utilizes our Deep CDR technology and Safe URL redirect service to expose and deactivate all potentially malicious links in an email.

High Performance

MetaDefender Email Gateway Security offers fast scanning without affecting email performance and is scalable to any email volume with MetaDefender's built-in high-performance architecture and load balancing
