Every email is a risk.
Most people find out
too late.
Guardian watches domains, badges every sender in Gmail and Outlook, and catches spoofed addresses before you click — or wire money — to the wrong person.
What Guardian does
Three layers. One subscription.
Domain Watcher
Add domains you care about. We re-check every one daily. If the score drops 15+ points or the grade changes, you get an email alert before you ever interact with that sender again.
Browser Extension
A live trust badge appears on every email sender in Gmail and Outlook. Green, yellow, or red — before you open the email. Works on link hover too: see the risk score of any URL before you click it.
BEC Fraud Detection
Business Email Compromise cost companies $2.9B last year. The attack is simple: a display name says "CEO" but the real domain is gmail.com. Guardian flags the mismatch before you wire the money.
Setup
Running in two minutes.
Subscribe
Two-minute setup. No DNS changes, no email rerouting, no IT department.
Add domains to watch
Drop in the domains you interact with regularly — vendors, banks, clients, partners.
Install the extension
One click from your Guardian dashboard. Drop your token in, and every email you open gets a live trust score.
