He says the new baseline capabilities will help security managers access comparative data that may have been unavailable or difficult to compile in the past.Also new in this release are customized alerts and additional device support. EnVision 2.003 lets security managers set parameters specific to their networks, and then the software uses the pre-set policies to alert them if a problem occurs.Network Intelligence also introduced the 50 Series Network Intelligence appliances. The 50 Series is designed for both small-to-midsize and enterprise companies. Network Intelligence says the appliances feature better processing power, storage capacity, network connectivity and data safety. Network Intelligence provides between 300 gigabytes and 3 terabytes of storage. And the newest version of the software can correlate up to 35,000 messages from up to 54 vendor source devices.The company also unveiled the 7550-HA Series application, which is a high-end appliance with embedded software that can handle more events per second.Network Intelligence software and hardware now support more security devices such as Jupiter Networks routers, Foundry Networks switches, nCircle's IP360 vulnerability management system, the Cisco Content Services Switch and Check Point Next Generation Application with SmartDefense.Network Intelligence competes with products from the likes of ArcSight, e-Security, Intellitactics and netForensics.
