DNS — CAA record

Certification Authority Authorization

A list of certificate authorities authorized to issue SSL certificates for this domain.

Why it matters

Prevents unauthorized parties from obtaining a certificate for your domain through any certificate authority.

What's missing without it

Without a CAA record, any certificate authority can issue a certificate for your domain — which is the foundation of a domain spoofing attack.

When it is used

When enhancing domain security, during audits, and in regulated industry deployments.

How we use it

0 issue "letsencrypt.org" — only this authority may issue a certificate.
