Certificate expiration hurts your business .
-
01
A website that doesn't work
An expired SSL certificate means people can not access the website anymore. Also, the visitors won't even know what happened exactly.
It could be due to a technical problem that will be fixed soon, a momentary operational issue, or the website getting hacked, which is severe enough to worry about. -
02
Missed sales opportunities
Modern web browsers prevent people from visiting websites if the TLS certificate is not functioning correctly.
The harsh 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 reassuring set of words. -
03
Damaged business reputation
Checking up on TSL certificates does not generally bring the business forward. Yet, letting it slip briefly could make it look like you don't have everything under control.
You'll never miss an update with our customizable reminders and multiple notification channels. -
04
Disrupted weekends
Imagine an expired certificate crashing your family weekend, that long-awaited hiking trip, or just a peaceful moment of zen.
Suddenly, you're not thinking about sunsets — you're scrambling to fix a crisis. Sound familiar? Yeah, we've been there too. -
05
Vulnerable servers
It's that simple—an outdated or faulty server configuration opens the door to vulnerabilities.
Let us keep an eye on your SSL/TLS setup and notify you the moment your configuration starts falling behind. Because when it comes to security, staying up-to-date is non-negotiable.
