What is a SSL/TLS Certificate?

Secure Sockets Layer (SSL) and Transport Layer Security (TLS) are code protocols that enable secure communication over a computer network. They are the backbone of all site security and, as a result, help ensure that customers can look at secure content on a website. All certificates expire after a few years, but as the duration depends on the particular certificate, keeping track of all of them can be problematic and they are easily overlooked. The expiration of certificates is intentional because all ciphers used to guarantee certificate encryption depreciate over time, so they need to be renewed to guarantee secure site access.

If one of the site’s certificates expires, many secure networks and browsers will notify customers who try to visit a certain page that the content is no longer secure. This prevents many of them from accessing the site and can cost the business potential customers. In addition, the lack of website integrity means that the site is also vulnerable to potential hacking attempts or data breaches, which could result in loss of data or damage to the business.

Other problems with certificates can occur when the certificate is registered to one domain (e.g. but users are accessing the site via a different address in the browser (e.g. If the users aren’t forwarded to the correct landing page, or the site owner lacks a certificate for all domains, the user will get an error and not be able to securely access site content, which undermines customer confidence.
