Download Suricata 1.4

Suricata is an open source network Intrusion Detections System (IDS), Intrusion Prevention System (IPS) and Network Security Monitoring engine. The development is being overseen by the Open Information Security Foundation, with support from the community and various manufacturers. Version 1.4 was released last Thursday and has improved performance, scalability and reliability. The changelog for this release can be found below.
