Certmon.net's answer:
Certmon.net's answer:
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.
Certmon.net's answer:
Certificate Monitor does one thing well - it keeps on eye on your SSL certificates and let's you know when they are about to expire. There is no bloat to the product with unnecessary features and complicated settings and options. Paste your domain name and let Certificate Monitor do the rest.
