The Network Intelligence Engine is particularly appealing from the end-user's perspective because of its powerful correlation capabilities, its plug and play deployment and its scalability. The appliance creates a complete picture of network usage, to verify security policy compliance, to generate alerts for possible security breaches, and to analyze and report on network performance. Relentless IT security threats generated from virus and worms, and legislation such as Sarbanes-Oxley require companies to deploy SEM technology and Network Intelligence enables businesses to quickly address these challenges by efficiently and cost-effectively deploying an appliance based solution.
