Millions of Tests

CheckTLS.com performs over one million tests every year. Our test count has gone up every month since we started in January 2010.

Monitoring and ForceTLS

Secure email is not "set it and forget it", and sooner or later something will go wrong. Make sure none of your emails ever show up on the cover of a news tabloid!

  • Monitoring


    • You can build custom email security monitoring with a Corporate Subscription to CheckTLS, or we can do your monitoring for you. Monitor your own infrastructure, your trading partners, or both.
    • Contact us at Info(at)CheckTLS.com for more information.
  • ForceTLS


    • ForceTLS is the ultimate in email security. Rather than testing or monitoring systems, it watches each live email from start to finish. If anything is amiss, that email isn't sent and you are immediately notified.
    • ForceTLS is available in our cloud or on your own servers (Linux or Windows).

Informal Guide To Our Tests

So you have an email address and you want to know if it can receive a secure email. Use our Basic Receiver Test.

If it shows that something is wrong, use the Detail output level on that same test to expose the problem.

Now you want to know if you can send a secure email. Use our Basic Sender Test.

But what about your home email account, can it send secure email? Remember it uses special settings from your Internet Provider to receive email from your PC. Use our Custom Receiver Test. It lets you enter settings like SMTP gateway, port, and your user-id and password.

Now your tablet PC won't send email. Should be easy to fix if you could just see what it's sending and receiving. Use our Watch A Connection Test. It can sit between the two sides and let you "listen in".

Informal Guide (Continued)

At work, company policy says you must use TLS with certain trading partners. If TLS fails on either end, no email should go through. Use our AssureTLS Receiver Test and AssureTLS Sender Test.

Your company sends to lots of email addresses, and you're asked to check them all. And you'd like to keep testing them every now and then, but only get notified if something's changed. Use our Batch Test.

What you'd really like is to alert your on-call people when Batch Test finds a problem. Use our MonitorTLS Web Service. It integrates with most monitoring and notification systems.

Despite your vigilance, something happens and a confidential email leaks out. The boss says: "Find a way to test that our emails are secure while they are being sent." Use ForceTLS. That's exactly what it does!

Your Exchange Server won't sync and you want to telnet to the IMAP port, but you forget the IMAP syntax and it's TLS encrypted besides. Use our IP Services Test.
