devtls
TLS, mail & config scanning for developers
A valid certificate hides a lot — mail ports that never encrypt, SPF records receivers quietly discard, a reverse proxy still negotiating TLS 1.0. devtls scans your web and mail stack, reads your Docker, Traefik, Nginx or Caddy config, and hands back the exact fix for every finding.
