This article describes DANE — a mechanism that uses DNSSEC-signed TLSA records to let domain owners publish and enforce TLS certificate validation via DNS, preventing STARTTLS downgrade attacks and reducing reliance on third-party CAs; it covers how DANE works step-by-step, TLSA record format, implementation guidance for SMTP email, interoperability with MTA-STS and TLS-RPT, adoption considerations, and recommends using DANE alongside DMARC for comprehensive email security.
