"That's how HTTPS monitoring should be done!"

Web is 77% encrypted - great! The bad news is we regularly suffer from expired encryption keys.

Web encryption is a must but we don't realize that it regularly expires. If it does, it means loss of business, customers, and search engine ranking.

  • You - just enter your main domain name
  • KeyChest - automatically finds your services

KeyChest finds new web services and lets you know before they break down due to expired encryption keys. It uses a database with over 6.5 billion entries to give you weekly reports as well as real time notifications. We believe that you at home, in small companies deserve the same or better than enterprises. Help KeyChest make a difference.

Computer security has become part of our everyday life - we all use internet and 77% of it is now encrypted. It became a necessary part of many businesses as users and customers notice. If you want to be visible on the internet, for people to find you on Google, you have to encrypt.

There's a downside to it - encryption keys may expire every 3 months. If it happens, it means no one can visit or use your website - it is down. Within a second of expiry.
No warning, no exceptions.
Lights are out.

It means losing business, visitors, customers, and search engine ranking. A lot of that can be automated but things do break down. I, as many others, have learnt the hard way how easy it is to lose track of whether your company websites, email servers, or applications are still up and running.
