It is free, easy to use for all Windows users irrespective of OS version or configuration with no need additional software (except browser).I can easily secure my personal computer remotely using an Internet connection without having any technical skills needed before hand like password setting etc. There are many other tools available in market but this one seems very reliable compared to them as they have lots more features than others which make it suitable even by novice user too. The only problem I face currently while trying to encrypt/decrypt files directly from PC itself instead of copying file into online cloud service like OneDrive has been solved long back when its first release was made public i.e., you don't required third party tool anymore now just copy your encrypted data over local disk drive then paste that folder content onto remote server via FTP transfer method where file will be decrypted automatically once uploaded there.
