Tarari Delivers First Multi-Gigabit, Scalable Regular Expression Processor.

SAN FRANCISCO -- Tarari's New Secret Agent Licensed to Kill SPAM, Phishing, Hacks, Insider Trading, and Viruses at Speeds up to 200,000 Messages Per Second.

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."

Additional features of the RegEx-CP include:

--The Tarari Regular Expression Analysis Tool (TREAT) enables developers to quickly and efficiently migrate existing regular expressions to a Tarari accelerated solution

--Support for comprehensive stingy and greedy matching provides broader support for applications that scan, index or report on data as well as for those performing heuristics, such as Bayesian analysis 

--Bit vector match reporting supports applications, such as Bayesian analysis, requiring information about only the existence of a match, not its location

--Nested state modeling enables sophisticated data analysis according to protocol modeling, which changes the nature of analysis based on the actual content of the data stream

--Optional "First Match" or "All Matches" reporting modes provide for highly efficient processing of match results

--Extended matching window provides matching capabilities for patterns extending across larger portions of the data

--Parallel processing hardware model enables developers to easily scale throughput capacity and regular expression capacity

Simultaneous Regular Expression Analysis

Anti-spam and anti-virus systems, intrusion detection and prevention systems, and regulatory, privacy and acceptable use enforcement all require the entire text of messages and web pages, including MIME attachments, to be examined for specific words and phrases. With roots in neurophysiology, mathematics and linguistics, a regular expression is a simple way to specify an extraordinarily complex set of pattern-matching rules when analyzing the content of e-mail and web traffic. With a regex, for example, an anti-spam solution could detect a target word or phrase no matter how a spammer attempted to disguise it (e.g. "v.i.a*g.r&a") -- if readers can detect the meaning, so can the regex analysis.

In network security applications, such as anti-spam and content filtering, false positives are as troublesome as missed detections. The accuracy of regex provides the ideal solution for precise modeling and detection. The high performance of Tarari's RegEx-CP, supporting up to 100,000 regexes at rates up to 200,000 messages/sec with up to 4 gigabits/second evaluations rates, delivers this precision detection at the rate demanded by today's networks.

Availability and Pricing

The RegEx-CP technology is available for evaluation as part of Tarari's RegEx-CP Development Kit. The kits consist of one production Tarari Content Processor, Simultaneous Regex Pattern Matching Agents, and API documentation. These kits are regularly priced at $4,995. Since Tarari Content Processors are fully reprogrammable, all existing customers and reviewers may also evaluate the new simultaneous regex agent on their existing Tarari hardware.
