Enter your domain and abr.cloud inspects your live TLS certificate — validity, expiry, issuer and chain — and tells you in plain language whether visitors get a secure padlock or a warning.
One quick verification, no account. We store nothing unless you start monitoring.
Your TLS (SSL) certificate is what turns on the padlock and encrypts traffic to your site. If it's expired, self-signed, or served with a broken chain, browsers show a scary warning and visitors leave. This check reads the live certificate the way a browser does and flags anything that would break trust.
Yes — free with a quick CAPTCHA, no account. It only reads your public certificate.
Start free monitoring from the result and we email you well before a certificate expires — the most common cause of sudden outages.
This reads the certificate and protocol; for a deep cipher/protocol audit use the TLS tools inside the abr.cloud app.
abr.cloud puts 80+ network & security tools behind one fast interface — with AI analysis and always-on monitoring.
