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.
RESULT
The complete findings with an AI-written summary and the exact fixes — yours to forward to whoever runs your website or email.
We keep watching around the clock and email you the moment it goes down, comes back, or a certificate is close to expiring. No card, no signup form — just confirm your email.
