Problems with legacy FTP
Using FTP to provide access to data for your business partners and clients will sooner or later confront you with the basic legacy problem of this protocol:
- Provides no transfers security
- Works unreliable across networks
- Needs special software
Provides no transfers security
When using FTP, the transport channels are not encrypted at all, this is just not specified in
the original FTP protocol. Even the authentifiation data is not protected that's why your username
and password will be transferred unencrypted.
This fact renders the employment of FTP very unsafe especially when using wireless networks as a every other party on the network may get the access data by simply listening to the traffic.
Works unreliable across networks
FTP is a rather complicated protocol which furthermore provides two modes called "active" and "passive" posing different requirements to the network configuration. The effective endpoints of the FTP communication are negotiated dynamically which only works across nethworks, when the firewalls understand the protocol and change their rules upon connection establishment.
In a company environment, you will often come across problems when using FTP and even for your customers, the stable operation of the protocol is not guaranteed. Using SFTP or the CargoLink technoloy instead provides a much smarter solution for transferring data files.
Needs special software
While most browsers do support FTP to download a single file, you will have to install a separate
software to use the full potential of FTP on your desktop.
Mobile devices like smartphones and tablets provide no FTP clients out of the box.
