Features Simple. Quick. Integrated.

Know when something changes
We will let you know if a certificate for your domain changes, (almost) expires or is revoked but still used.

Be notified quickly
Our bots crawl your https://domains every 5 minutes for the most important issues, so you are notified almost instantly in case something got misconfigured.

Insights in your security seals
We make sure your SSL / TLS configuration is correct, modern and your certificates are valid and trusted by all browsers. Get scores from Qualys SSL Server Test right on your dashboard.

On all levels
DNS is never the issue... except when it is! We monitor your DNSSEC & DANE configuration. Running on multiple IP's? We test 'em all! So you know if IPv6 is not working but IPv4 is fine or that one pesky load balancer forgot to renew it's certificate.

Notifications to all the important places
We support notifying about changes through e-mail, Telegram, Slack, Discord, Pushover and many more. Setup channels to route different notification types to the right places. For example: notify about certificate changes in Slack, but sent expiry notifications to your e-mail.
