We believe that it is important to combine flow monitoring with security and packet to disk. This in an integrated manner, and not by using different un-correlated applications. Cento is the next generation probe able to generate flows at 100 Gbit line rate using an x86 PC and a 100 Gbit NIC on top of PF_RING ZC, while being able to selectively send packets to IDSs or packet-to-disk applications. In essence what we want to achieve with cento is: flows for everything, packets for something.
While we plan to release Cento sometime this spring, for those interested in testing it, you need to go to packages.ntop.org and install the development version of the nProbe package that includes a new binary named cento.
