The OISF development team is proud to announce Suricata 2.0. This release is a major improvement over the previous releases with regard to performance, scalability and accuracy. Also, a number of great features have been added.

The biggest new features of this release are the addition of “Eve”, our all JSON output for events: alerts, HTTP, DNS, SSH, TLS and (extracted) files; much improved VLAN handling; a detectionless ‘NSM’ runmode; much improved CUDA performance.

The Eve log allows for easy 3rd party integration. It has been created with Logstash in mind specifically and we have a quick setup guide here: Logstash_Kibana_and_Suricata_JSON_output
