• 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

Not Configured (Any CA can issue certificates)

CAA Issues

• No CAA records configured - any CA can issue certificates

Recommendations

• Implement CAA records to restrict which CAs can issue certificates for your domain
• This adds an extra layer of security against unauthorized certificate issuance
• Example: Add CAA record 'example.com. CAA 0 issue "letsencrypt.org"'
• Consider adding 'iodef' record to receive security incident reports
