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

Recommendations
- • Consider using critical flag (flags=128) for stricter CAA enforcement
- • Consider adding 'iodef' records to receive notifications about unauthorized certificate issuance attempts
- • Consider adding 'issuewild' records to control wildcard certificate issuance
