The challenge of securely storing and transporting large files across a corporate Wide Area Network

The majority of organizations that use Wide Area Networks (WAN’s) to connect Local Area Network’s (LAN’s) together have a requirement to transfer large amounts of data “across the wire”, between different locations. A number of widely available desktop applications such as Microsoft Outlook and Windows Explorer provide built-in functionality that support the basic data transfer needs of most users (e.g. attaching a file to an email, creating a “share” on a remote machine and mapping a local drive to that share), but such solutions have limitations when there is a requirement from backend applications or system administrators to reliably transfer large files that are often numerous Gigabytes (Gig), or more, in size. This challenge is further complicated when the data is of a sensitive nature and needs to be transported securely, on a repetitive (i.e. automated) basis, and must be held in a secure format before and after transmission.

Storing and transporting large files in this context is constantly at risk and needs to be protected. This article makes it perfectly clear how and why.
