WebCourier uses a HTTPS connection, the same as used for payment and sensitive transactions on the web. HTTPS creates a secure channel and protects from eavesdropping and man-in-the-middle-attacks. Before your files leave your computer, they are secured with 2048-bit RSA encryption, which is equal to, or higher than industry standards.


In comparison, the normal FTP specification is an inherently unsecure method of file transfer that allows the files to be easily intercepted by unauthorized persons.
