Taking away the complexity of SSL monitoring
The world of SSL/TLS has become very complex. We can take away that complexity for you and present you with an easy-to-use monitoring solution for your SSL certificates.
We'll monitor your website's certificate expiration dates and send you a notification when they're about to expire.
- Certificates form a chain of trust. We don't only monitor your domain (leaf) certificate, but every intermediate too.
- Other monitoring tools often only check the domain certificate.
Your visitors will get an error message
If you're using old security algorithms, some browsers will block access to your site. We detect those old ciphers and report them to you.
Error messages like this negatively affect your brand image (and ultimately, your bottom line) as they make your website feel inaccessible and untrustworthy. Keeping track of your certificates avoids these unpleasant surprises.

Let’s get technical (if you’re into that)
You don’t need to be computer savvy to set up our tool. But if you are, we’re happy to explain exactly how it works and how you can customize Oh Dear to your specific needs.
Certificate Chain Validation
A chain is only as strong as its weakest link. SSL certificates are the prime example.
We don't just monitor your domain certificate but will check every intermediate certificate too, up to the root certificate, to verify the chain of trust.
We look for SHA-1 certificates, revoked or distrusted root certificates, ... each of these can cause your site to be unavailable. And none of those changes are in your control, these decisions get made by the Certificate Authorities (CAs) or the browsers themselves, coordinated via the CAB Forum.
In a chain, every certificate could cause a problem for your website. We monitor each and every one of them.
Certificate Change Detection
When a certificate is changed, we'll let you know straight away. We'll show a clear before/after comparison of the certificates we found, so you can verify that this change is both intentional and correct.
A changed certificate could be a renewal, but might also be a move to a new server (with a DNS change) or a domain hijack. We'll make sure you see each change!
Certificate Transparency Monitoring & Alerting
All issued SSL certificates need to be published to known Certificate Logs. As a result, every certificate issued becomes public knowledge.
We monitor those Certificate Transparency Logs and will alert you whenever a new certificate is issued for one of your domains. You can decide if it was on purpose by you or from a malicious actor and act accordingly.
