Key features

 * Clear output: you can tell easily whether anything is good or bad

 * Ease of installation: It works for Linux, Darwin, FreeBSD and
  MSYS2/Cygwin out of the box: no need to install or configure
  something, no gems, CPAN, pip or the like.

 * Flexibility: You can test any SSL/TLS enabled and STARTTLS service,
  not only webservers at port 443

 * Toolbox: Several command line options help you to run YOUR test and
  configure YOUR output

 * Reliability: features are tested thoroughly

 * Verbosity: If a particular check cannot be performed because of a
  missing capability on your client side, you'll get a warning

 * Privacy: It's only you who sees the result, not a third party

 * Freedom: It's 100% open source. You can look at the code, see what's
  going on and you can change it. Heck, even the development is open
