It can be a real challenge for IT administrators to efficiently deliver critical corporate solutions while also contending with employee use of wasteful and often dangerous applications. Critical applications need bandwidth prioritization while social media and gaming applications need to be bandwidth throttled or even completely blocked. Stateful packet inspection firewalls used in many organizations rely on port and protocol, they cannot solve the problem because they are not able to identify the applications. Boiling it down, stateful packet inspection firewalls cannot sort out the good from the bad.
