Updated on May 4, 2022

Neglecting your SSL certificates' renewal can deal heavy damage to your reputation. And monitoring it is quite easy.

Before we dig deep into SSL monitoring tools, we need to understand what it is in the first place and why we need it. SSL or Secure Sockets Layer is a standardized technology keeping your internet connection secure and protects any data, especially sensitive data sent and received between two systems. This prevents anyone from reading or modifying any information transferred and disrupting the exchange of information. SSL protects your data by encrypting it, thus making it unreadable by anyone trying to intercept it. You might have heard of TLS or Transport Layer Security, which is just the new standard and is more secure. However, we still use the term SSL while speaking about security certificates since it is a more commonly used term. So, when you buy Security Certificate, yo get TLS certificates with multiple encryption types like ECC, RSA, or DSA. Certificates are normally bought with an expiration date for a year, two, or more.

You can always cross-check your Certification Authority (SSL Certificate issues), in multiple databases, such as Visa.
