SSL/TLS & Website
Certificate name check
The certificate has to name the exact hostname a visitor types. If it names something else, browsers refuse it.
Check this on your own domain now. It is free with a DomainGuard account, reads only public records, and gives you a report you can send to whoever runs your website.
What we look at
We compare the names on the certificate your site serves with the hostname we connected to.
Why it matters to your business
This usually happens after a site moves, or when www and the bare domain are set up differently. Visitors who type the "other" version get a warning page, and many never try again.
How to fix it
- Issue a certificate that covers both yourdomain and www.yourdomain.
- A wildcard (*.yourdomain) covers one level of subdomain only.
If you would rather not touch DNS or server settings yourself, forward this page and your report to whoever manages your website, or ask us to do it.
Keep an eye on it
A one-off check tells you how things stand today. On Starter and up, DomainGuard re-checks the domains it watches every day and alerts you in the app when something important changes, so you hear about it before a customer does.
