Product overview
MxGuard is a cloud-based email security gateway. It sits in front of your existing mail server as your MX record, scores every inbound message in real time, and forwards only clean mail to your mailbox.
MxGuard runs in our UK-based cloud. Customers point their MX records at our infrastructure and start receiving filtered mail within minutes. There's nothing to deploy on your premises, no agents to install, no firewall rules to add.
Subscription pricing means no up-front capital investment and no surprise upgrade costs. Scale up or down month-to-month as your business changes.
For decades, mail security has meant stacking together open-source rule engines and Bayesian filters — or paying enterprise-suite prices. MxGuard replaces both.
eFa, SpamAssassin, Rspamd, MailScanner. Hand-tuned rule trees that are slow to adapt to modern spam patterns, produce frequent false positives on legitimate bulk mail, and require expert administration to maintain.

Enterprise email security suites cost thousands per year, bundle features you'll never use, and lock you into multi-year contracts. MxGuard gives you the core capabilities at a fraction of the cost with month-to-month billing.
