Free Security Scan

Know your external exposure in 60 seconds

Run a free passive security scan of your domain. SecByte checks DNS, email spoofing protection, TLS, security headers and public exposure in under a minute — no agent, no credentials, no scanning of your servers.

Passive reconnaissance only — we query public DNS, certificate transparency logs and your public HTTP responses. No intrusive testing is performed, and no authorisation is required.
