Suricata is the next generation open source IDS/IPS developed byt the Open Information Security Foundation. It is a pleasure to announce that ntop has joined the core development team as the Linux version of Suricata is based on acceleration provided by PF_RING. In the near future PF_RING will be extended so that it can also accelerate packet transmission in order to move the Suricata IPS performance to the next level.
