 What is Suricata
 ================
 
-The Suricata Engine is an Open Source Next Generation Intrusion
-Detection and Prevention Engine. This engine is not intended to just
-replace or emulate the existing tools in the industry, but will bring
-new ideas and technologies to the field. The Suricata Engine and the
-HTP Library are available to use under the GPLv2.
+Suricata is a high performance Network IDS, IPS and Network Security Monitoring engine. It is open source and owned by a community-run non-profit foundation, the Open Information Security Foundation (OISF). Suricata is developed by the OISF.
 
-IDS/IPS
--------
-
-Suricata is a rule-based ID/PS engine that utilises externally
-developed rule sets to monitor network traffic and provide alerts to
-the system administrator when suspicious events occur. Designed to be
-compatible with existing network security components, Suricata
-features unified output functionality and pluggable library options to
-accept calls from other applications.  The initial release of Suricata
-runs on a Linux 2.6 platform that supports inline and passive traffic
-monitoring configuration capable of handling multiple gigabit traffic
-levels. Linux 2.4 is supported with reduced configuration
-functionality, such as no inline option.  Available under Version 2 of
-the General Public License, Suricata eliminates the ID/PS engine cost
-concerns while providing a scalable option for the most complex
-network security architectures.
-
-Multi-threading
----------------
-
-As a multi-threaded engine, Suricata offers increased speed and
-efficiency in network traffic analysis. In addition to hardware
-acceleration (with hardware and network card limitations), the engine
-is build to utilise the increased processing power offered by the
-latest multi-core CPU chip sets. Suricata is developed for ease of
-implementation and accompanied by a step-by-step getting started
-documentation and user manual.
-
-Development and Features
-------------------------
-
-The goal of the Suricata Project Phase 1 was to have a distributable
-and functional ID/PS engine.  The initial beta release was made
-available for download on January 1, 2010.  The engine supports or
-provides the following functionality: the latest Snort VRT, Snort
-logging, rule language options, multi-threading, hardware acceleration
-(with hardware and network card dependencies/limitations), unified
-output enabling interaction with external log management systems,
-IPv6, rule-based IP reputation, library plug-ability for interaction
-with other applications, performance statistics output, and a simple
-and effective getting started user manual.
+About the Open Information Security Foundation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-By engaging the open source community and the leading ID/PS rule set
-resources available, OISF has built the Suricata engine to simplify
-the process of maintaining optimum security levels.  Through strategic
-partnerships, OISF is leveraging the expertise of Emerging Threats
-(www.emergingthreats.net) and other prominent resources in the
-industry to provide the most current and comprehensive rule sets
-available.
+The Open Information Security Foundation is a non-profit foundation organized to build community and to support open-source security technologies like Suricata, the world-class IDS/IPS engine.
 
-The HTP Library is an HTTP normaliser and parser written by Ivan
-Ristic of Mod Security fame for the OISF. This integrates and provides
-very advanced processing of HTTP streams for Suricata. The HTP library
-is required by the engine, but may also be used independently in a
-range of applications and tools.
