I like that it's easy to use, secure enough without too many bells & whistles (yet), doesn't slow down your computer when you're working with large encrypted documents/files etc., has good support from technical people who can help if needed in case of problems or questions about how things work.
It does not have an option where we could set up password rules such as "this user cannot change their own passwords". We've been using this software since 2012 but haven't had any issues yet other than some occasional slowness during file encryption / decryption which was easily solved by restarting our computers after starting File Encryptor Mini Lock applet. This program protects all types of sensitive data including financial information so far no complaints!
