How healthy is your domain?

Enter your domain. abr.cloud checks the things that actually break — email spoofing protection (SPF/DMARC), TLS certificates, DNS and security headers — and explains every finding in plain language. Passive & harmless: we only read public records, like any visitor could.

One quick verification, no account. We store nothing unless you ask for the report or start monitoring.
