SAN FRANCISCO -- With network attacks continuing to overwhelm existing security defenses, companies now have access to a new "secret agent" that will allow them to keep pace with whatever network attackers and compliance violators throw at them. Tarari Inc., the award-winning acceleration company, has answered the call by releasing Version 3 of its Regular Expression Content Processor (RegEx-CP), the first silicon-based multi-gigabit, scalable regular expression (regex) content processor. Tarari provides content processing technology in the form of boards and ASICs that are designed to snap into security appliances, servers, blades, and networking infrastructure, delivering wire-speed performance and CPU offload via purpose-designed silicon technology. RegEx-CP V3 is based on Tarari's unique content processing technology and represents a significant advance in the science and utility of regex-oriented data assessment.

Regex has become the de facto technology for characterizing how data is evaluated for a broad range of industry technologies. However, software implementations of regex are conventionally processor-intensive and suffer significant performance degradation as evaluation requirements expand in depth or complexity. Tarari's RegEx-CP technology eliminates this performance degradation while boosting assessment capacity.

Tarari's RegEx-CP is the first solution to process over 200,000 messages/sec, while simultaneously analyzing up to 100,000 expressions. With RegEx-CP, vendors can dramatically and cost-effectively improve the efficiency of a broad range of gateway and server solutions, including content filtering, anti-spam protection, intrusion detection and prevention systems, firewalls and business and regulatory policy enforcement.

Regular expressions are the most accurate way to implement content filtering for network security solutions, but processing a regex relies on compute-intensive pattern matching, which dramatically reduces network and server performance. Tarari's RegEx-CP uses purpose-designed silicon logic to accelerate and offload regex pattern matching at speeds up to 4Gbps, and processes up to 100,000 expressions simultaneously. Tarari's RegEx-CP uses industry-standard POSIX 1003.2. Developers access the RegEx-CP engine through a standard API, minimizing time to market. Tarari Content Processors are also fully field reprogrammable.

"Content filtering has historically been an inverse proportion problem: the greater the need for filtering, the worse the solutions perform," said Randy Smerik, CEO of Tarari, Inc. "Today, however, developers need no longer fear performance degradation resulting from software-based regular expression implementations. With the extreme acceleration of Tarari's RegEx-CP, developers can cost-effectively create far more powerful solutions that beat spammers and other 'cyber-villains' at their own game."
