Recommendations
- • Add Strict-Transport-Security header with max-age of at least 1 year
- • 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 Issues
- • CRITICAL: Current certificate issuer 'C=US, O=DigiCert Inc, CN=DigiCert Global G2 TLS RSA SHA256 2020 CA1' is NOT authorized by CAA records. Authorized CAs: letsencrypt.org, pki.goog, sectigo.com, globalsign.com
Recommendations
- • Consider using critical flag (flags=128) for stricter CAA enforcement
- • You have authorized 4 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
