As founder and developer I have built many web services. They are hosted on different platforms depending on my needs. This means I have different SSL certificates all over the place issued by various vendors and keeping track of when they expire was a nightmare. I decided to build Certificate Monitor to constantly keep an eye on my certs and alert me when they are due to be renewed.
