Arbor Networks Offers Virtual Network Security Tool

Arbor Networks, whose technology detects abnormal network traffic flow, now offers its PeakFlow monitoring tool for use in virtualized environments. PeakFlow X Virtual 4.2 is the alternative to PeakFlow X software that monitors packet flow through network routers and switches, alerting system administrators if traffic spikes above normal patterns, such as in the case of a dedicated denial of service (DDOS) attack. The virtual version of the software is designed to run in VMware's ESX and ESXi hypervisors.

PeakFlow SP was introduced in 2000, targeting telecommunications service providers such as Verizon, AT&T, British Telecom and others that operate vast global networks and also serve as Internet service providers (ISPs). The appliance sampled about one packet in 100,000 to extrapolate from there network traffic patterns. In 2006, Arbor introduced PeakFlow X, which was targeted at enterprises and sampled 100 percent of network traffic, said Tom Bienkowski, director of product marketing for Arbor Networks.
