Distributor of Diagnostic Imaging Products Will Use TriGeo's Event Correlation and Active Response to Manage Network Security and Support Sarbox Compliance

POST FALLS, ID 09/27/2005 -- TriGeo Network Security (www.trigeo.com), the pioneer and leader of Automated Remediation through Intelligent CorrelationTM, today announced that Hitachi Medical Systems America, Inc., a division of Hitachi, Ltd., (NYSE: HIT), headquartered in Tokyo, Japan, selected TriGeo Security Information Manager (TriGeo SIM), for network defense, security management and policy enforcement. With TriGeo, Hitachi Medical Systems America, Inc. will manage, track and respond to suspicious network activity, as well as, comply with various regulations, including Sarbanes-Oxley and COBIT.

"The main reason we are implementing the TriGeo SIM is because it was the only proactive solution," James Hallman, Manager, Information Services with Hitachi Medical Systems America (HMSA). "Everything else we looked at was reactionary and required some form of manual intervention. TriGeo actually suspends suspicious activity on the network as it is happening and notifies my staff of the activity."

TriGeo takes a unique approach to security information management by combining real-time log analysis and event correlation with the industry's largest repository of active responses. This combination will be instrumental in helping HMSA identify suspicious and malicious activity and enforce network policy, without complex programming.

Another key factor in HMSA's decision to select TriGeo was its low cost of ownership. "The moment I saw the product I said to myself, 'This looks great,' said Hallman. "It will do everything that I want and I won't have to hire an FTE to manage it. We have to have it."

"Sophisticated security management solutions with robust, real-time features traditionally come with a hefty price tag and have previously been available only to Fortune 1000 companies," said Michelle Dickman, CEO of TriGeo Network Security. "We recognized that the rest of the market faced the same security challenges and regulatory pressures, and needed a product that didn't require a dedicated security team."

TriGeo is designed for rapid implementation, configuration and tuning. It provides hundreds of out of the box correlation rules, and has the industry's most flexible and powerful correlation rule builder. It integrates with virtually every network infrastructure component from firewalls to anti-virus, supports a variety of operating systems, bundles intrusion detection and produces over 140 stock reports. TriGeo is a significant weapon in any network security and regulatory compliance arsenal.
