ABOUT THIS TOOL
What the Domain Security Check reviews
The Full Check combines multiple independent signals into a readable domain-security posture. It reviews email authentication, mail routing, transport-security records and selected DNS/TLS controls. The score is a diagnostic aid, not a guarantee of deliverability, compliance or protection.
