Innovative Advanced Protections

Containment protects from the newest forms of ransomwares, zero-malwares and other advanced threats. The Valkyrie file verdict system analyzes unknown files. Users are free to open, execute and use the attachments with ZERO risk of infection.

Comodo's unique containment technology ensures that risks are fully contained before reaching the end point, so there is no risk of infection, even from the newest malware. Comodo Dome Antispam uses the Valkyrie file verdict platform. It utilizes a combination of static, dynamic and advanced behavioral analysis to inspect files as they are being downloaded.

Stable Filtering

Stable filtering restores bandwidth that was lost due to unsolicited email traffic, reducing the load on your email server.

Unwanted traffic is filtered before it reaches your network, while the email you want is right there. And you can do with those emails what you will.

Efficient System

Efficient System restores productivity to users by identifying and deleting spam.

We all face torrents of unsolicited emails every day. The lost employee time is significant. Plus, how many of these unknown files contain malware like viruses and trojans?
