  • Improve CSP by adding more specific directives and removing 'unsafe-inline'
  • Add X-Frame-Options: DENY or SAMEORIGIN to prevent clickjacking

Configured (Restricts certificate issuance)
Current Issuer
Authorized (Matches CAA policy)
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
  • Consider adding 'issuewild' records to control wildcard certificate issuance
