Is your site's security certificate healthy?

An expired or misconfigured certificate throws a scary warning at every visitor and can knock your search ranking. Type your site below and we will check whether the certificate is valid, trusted, how soon it expires, and whether the server still allows outdated, insecure connections.

No login and nothing to install. We only read the certificate your site already presents to every visitor. Please only check sites you own or look after.

What we check

Whether the certificate is in date and how many days are left, whether browsers trust it and it matches your site name, and whether the server still accepts old TLS 1.0 or 1.1, which fails modern security standards like PCI.

Why it matters

A lapsed certificate is one of the most common and most visible website failures. It blocks visitors with a full page warning, and it almost always happens because an auto renewal quietly stopped working.

Want us to look after it?

We host and maintain websites for businesses across Norfolk and Suffolk, with certificates renewed automatically and monitored so they never lapse.
