Silk — website security scanner

Enter a URL and Silk runs a passive security scan — your TLS certificate and protocols, the HTTP security headers that protect visitors (CSP, HSTS, clickjacking, MIME-sniffing), and cookie flags — then grades it with the exact fixes.

Runs on our servers — a single GET plus a TLS handshake to inspect your certificate (no login-walls, no aggressive probing). We store nothing.
