Google Web Risk Lookup
Google Web Risk adds checks for known phishing, malware and unwanted-software URLs to Click-time Link Protection.
Available with Email Security when server-side Google integration, domain link wrapping and required protection controls are enabled. Checks run before supported destination and redirect requests and again on Continue. Backup MX does not include content inspection.
What is checked?
Wrapped HTTP(S) links and supported redirect destinations
Supported password-form actions during static inspection
Current domain authorization and policy at click time
Privacy and inspection limits
Full checked URLs, including path and query, are sent to Google and may contain personal information or access tokens. No email body, attachment, sender, recipient or SecuraWall token is submitted. If enabled checks fail or the local API quota is exhausted, the Continue option is unavailable. A URL that is not listed may still be unsafe. Static inspection does not execute JavaScript.

BUILT ON FIELD EXPERIENCE
From hands-on experience to SecuraWall MailFlow
We worked with a wide range of email security and continuity products in real customer environments. That hands-on experience led us to develop SecuraWall MailFlow. Over time, it evolved into a commercial service with two base packages—Backup MX and Email Security—and an optional SMTP Relay add-on.
