Cisco StealthWatch FlowSensor 4200 - network monitoring device

The Stealthwatch FlowSensor uses a combination of deep packet inspection and behavioral analysis to identify applications and protocols in use across the network - no matter if they are plain text or use advanced encryption and obfuscation techniques. It also gathers packet-level performance statistics at a fraction of the cost of traditional probe-based devices, playing a key role in troubleshooting both security incidents and application performance problems.
