Free Security Scan

External, non-intrusive · enter a domain to start

Run a free external scan of your domain — security headers, TLS/transport, and public exposure signals. No agent, no login. Results poll in-browser.

Scans an external surface only; submitting a domain you don't own is not authorized. The scan API is served by KENSAI; this page runs from gokensai.com and calls the KENSAI API cross-origin.
