Analyze your site

A free outside-in check of HTTPS, security headers and email spoofing protection

Only scan domains you own or are authorized to test.

A scan only sees the surface.

The analyzer checks what's publicly visible. A penetration test goes further: we try to exploit what we find, then tell you how to fix it.
