Recommendations
  • • Consider adding 'preload' to HSTS for maximum security
  • • Add Content-Security-Policy header to prevent XSS attacks
  • • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking
  • • Add X-Content-Type-Options: nosniff
  • • Add Referrer-Policy header (recommended: strict-origin-when-cross-origin)
  • • Consider adding Permissions-Policy to control browser features

CAA Records (Certificate Authority Authorization)

CAA Records
Configured (Restricts certificate issuance)
Current Issuer
Authorized (Matches CAA policy)
Authorized CAs
comodoca.com digicert.com ; cansignhttpexchanges=yes letsencrypt.org pki.goog ; cansignhttpexchanges=yes ssl.com
Wildcard CAs
pki.goog ; cansignhttpexchanges=yes ssl.com comodoca.com digicert.com ; cansignhttpexchanges=yes letsencrypt.org
Recommendations
  • • Consider using critical flag (flags=128) for stricter CAA enforcement
  • • You have authorized 5 CAs - consider limiting to only the CAs you actively use
  • • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
