Tailor protection to your company. Every tool lives in one dashboard.
Suspicious messages aren't deleted - they're held in quarantine. Review a message, release it with one click, or delete it permanently.

Every message and attachment is scanned for viruses, trojans, and phishing links. More than 5,000 threats blocked daily - before a message reaches the recipient.
Just change your MX record - all inbound mail routes through MXGuard. Your server stays untouched.
Distributed infrastructure across multiple data centers. No message is ever lost.
