Flow analysis is very important in IT operation; however, traffic collection and analyzing can make CPU utilization of routers and switches too high.

Packet sampling misses some traffic and thus may cause the analysis result different from the reality.

If you worry about these problems, N-Probe is the best solution for Flow analysis!

Pros and cons

Added-value Function-- Built-in DNS Layer 7 Exploring

N-Probe’s added value function includes built-in DNS layer 7 exploring function, which can send NX Domain message from DNS server to N-Cloud/N-Reporter as Syslog data, and N-Cloud/N-Reporter will make NX Domain list dynamically. N-Cloud/N-Reporter can automatically write the list in security devices of some brands for collaborative defense (the brands and models that can do collaborative defense are keeping upgrading; please contact N-Partner for more details). The devices will filter NX Domain query, so the DNS server will not be influenced by enormous NX Domain query attack.
