MetaDefender Email Gateway Security

Stop Email Threats that Evade Sandboxes

MetaDefender Email Gateway Security protects against email borne threats that evade sandboxes and bypass advanced threat protection solutions, such as those offered with Office 365 and G Suite. Using industry-leading multiscanning and deep content disarm and reconstruction (Deep CDR), MetaDefender Email Gateway Security prevents zero-day attacks and unknown threats, as well as providing close to 100% known threat detection, without affecting email server performance. MetaDefender Email Gateway Security also includes proactive data loss prevention (Proactive DLP) capabilities to detect and block sensitive content in emails.


Neutralize Malicious Emails

Our Deep CDR technology, also known as Deep Content Disarm and Reconstruction, disarms each email body and 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 30+ 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 Sensitive Information

MetaDefender Email Gateway Security offers proactive data loss prevention (Proactive DLP) to prevent emails with sensitive content from 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.

Flexible Deployment

MetaDefender Email Gateway Security works with on-site email servers such as Microsoft Exchange, as well as cloud email services such as Office 365, G Suite, and hosted Exchange. It can also be used to enhance the security of any secure email gateway.

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. Find out more about recommended configurations, based on amount of mailboxes and email volume.
