CRAWLEY, U.K. -- Spirent Communications plc (NYSE: SPM; LSE: SPT), a global provider of performance analysis and service management solutions, announced the release of ThreatEx 2.50, which offers the most powerful security testing functionality available today. Through a cutting edge application known as protocol fuzzing, this new release extends ThreatEx's security testing coverage and allows users to find unknown vulnerabilities or weaknesses in their network's security devices, infrastructure or host applications.

ThreatEx is a powerful security testing solution that allows users to evaluate system integrity against thousands of known threats and vulnerabilities. With the addition of protocol fuzzing, ThreatEx allows users to evaluate their systems in such a way so that weaknesses are pinpointed even before the exact threat is known. This capability goes way beyond pass/fail virus or threat testing to allow proactive system strengthening and robustness testing for network device or software development applications. ThreatEx with protocol fuzzing allows users to pinpoint the exact data pattern that causes an error or fault in a primary system.

"Attackers have long exploited the fact that even subtle variations in protocols can cause compromise or failure of networked devices," says David Newman, president of Benchmarking Consultancy Network Test. "Fuzzing technology helps level the playing field, giving implementers a chance to subject their systems to millions of variations in traffic patterns before the bad guys get a chance to."
