Recommendations

• Increase HSTS max-age to at least 1 year and add includeSubDomains
• Improve CSP by adding more specific directives and removing 'unsafe-inline'
• Consider adding Permissions-Policy to control browser features

CAA Records (Certificate Authority Authorization)

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
