Know how automated attackers see your business. Enter your website to see the weaknesses anyone on the internet can spot, which ones matter, and how to fix them yourself.
Discover. Fix. Confirm.
Discover
We check your email protection (SPF, DMARC), your website's security certificate, HTTPS and browser protections: the same public signals automated attack tools look for first.
Fix
Each issue is explained in plain language, with step-by-step instructions for common setups like Microsoft 365, Google Workspace and Cloudflare, and a note on whether you can do it yourself.

Safe by design
We only look at what's already public, and we never try to break in. Anyone can start a check, so detailed results are shown only to people who verify they work at the business. How it works
