Certificate expiration and your business

A website that doesn't work

Expired SSL/TLS certificate means people can not access the website anymore.

Your visitors won't even know what exactly happened.
Perhaps it's a technical problem that's going to be fixed soon or some kind of an operational issue, or the website had been hacked.

Missed sales opportunities

Modern web browsers prevent people from visiting websites if the TLS certificate is not functioning properly.

The intimidating wording browsers use to warn your visitors makes it even worse. Chrome, for example, starts with this:

Attackers might be trying to steal your information ...

Not the most calming set of words.

Damaged business reputation

Checking up on TSL certificates is not something that truly brings you forward. Yet letting it slip for a brief moment could make it look as though you don't have everything under control.

Disrupted weekends

Imagine an expired certificate all of a sudden interrupting your family weekend or that long-awaited trip, or just a serene moment of contemplation.

Sounds ridiculous, isn't it?
Yet it happens, and you never know when exactly the message will arrive next time.

Vulnerable servers

As simple as that - outdated server configuration makes a website more vulnerable.
You'll get notified when your server's TLS configuration goes out of date.

Our offer

We do a single thing, and we do it right. Get notified when a certificate expiration date approaches. Free plan available, no strings attached.

How it works

SSLreminder offers certificate monitoring service by periodically checking the TLS certificate of your website.

Here are 3 simple steps to get started:

  1. Add a new domain name in your dashboard (bulk add is available)
  2. The system will check the SSL/TLS certificate's validity (and other parameters) immediately
  3. If an issue is discovered, you will receive an email describing the situation and the possible ways to fix it

Every domain name under your account is checked daily.

We send expiration reminders based on the schedule below. It can be adjusted in account settings.
