SSL/TLS & Website

HTTPS connection check

Whether your site completes a secure HTTPS connection with a certificate browsers trust.

Check this on your own domain now. It is free with a DomainGuard account and works on any domain. The check reads only what your domain publishes, and gives you a report you can send to whoever runs your website.

What we look at

We open an HTTPS connection to your site and check that the handshake succeeds and the certificate is trusted.

Why it matters to your business

If this fails, visitors see a full-page browser warning instead of your website, and most of them leave. Search engines rank sites without working HTTPS lower, and payment and contact forms stop being safe to use.

How to fix it

  1. Install a valid certificate for the domain. Most hosts and Cloudflare provide one free.
  2. If you use Cloudflare, check the SSL/TLS mode is Full (strict) and that your origin server also has a valid certificate.

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.

Check your own site for this

A free outside-in check of your website, email and domain records, with what to fix first. No card and no password to choose.

Free, no card, no password to choose: your name and email make a free DomainGuard account that keeps the report, and we email you a link to confirm it. We only read what the internet can already see.

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.
