When it comes to keeping websites secure, one of the most important things to do is to make sure that the Transport Layer Security (TLS) certificates don’t expire. TLS certificates provide an important layer of protection for websites and other web-based services, and if they expire, they can prevent visitors from accessing the sites.

Example of expired SSL

Do you need to keep track of your TLS/SSL certificates but don’t know where to start? With NEO Sense, you can easily monitor TLS/SSL certificates, ensuring that all certificates stay up-to-date and secure.

This article will show you how to monitor your TLS/SSL certificates using NEO Sense. So, without further ado:

Meet NEO Sense: The web application version of Monika. It simplifies the use of Monika through an easy-to-use dashboard interface. It provides a graphical user interface for you to create probes, set alerts and notifications, and check the validity of your TLS/SSL certificates.

Using NEO Sense, you can probe your websites and endpoints from multiple locations. Below is the list of available locations currently:

  • Jakarta, Indonesia
