The typical Company of today
In today's fast paced economic setting, companies - be it in the manufacturing domain / retail / telecom, are finding it increasingly important to be nimble.What better way to transform a large mammoth organization to a lean and agile unit than by IT ? Especially with the coming of internet as a principal form of communication and business engagement, companies have been able to cut the costs associated with travel and document transfer. Companies today rely on their corporate network for things as simple as sending payslip statement to conducting remote business meetings over the web. Especially powerful Supply chain management solutions, which are reliant on the internet, make it possible for inventory replenishing in real-time.
Imagine the case of a large company whose sales happen online. Even a few minutes of network outage could mean lost dollars and potential customers.
Against this backdrop, the importance of having the WAN network up and running becomes critical. As a network administrator you have to ensure that your staff and customers are able to access the resources( any URL/Podcast/webcast) at anytime they need - and in a way that the overall bandwidth consumption does not shoot through the roof, resulting in a total network fiasco. You need to have a means of being alerted upon any threshold violations, so that you don't end up monitoring the network activity all the time.
Also a tab on any unwarranted access to unnecessary/objectionable content can be easily had. This in a big way free-up your network for more vital activities. To Illustrate: Blocking all access to downloading music/video content off the web could result in a substantial bandwidth saving for someone wanting to setup a video conferencing session with the client.

Besides they did not have a clear visibility into how bandwidth was used in their network and who was using it. So they wanted a reporting system that would let them know the bandwidth usage details on WAN connections as well as at the aggregation points for capacity planning and traffic analysis at per host and per application granularity.
