FORT LAUDERDALE, Fla. -- Citrix Systems, Inc. (CTXS), the global leader in access infrastructure solutions, today announced it has completed the acquisition of Sunnyvale, CA.-based Teros, Inc., a privately-held provider of application security solutions. Financial terms were not disclosed.

Founded in 2000, Teros is a market share leader in the emerging Web application firewall market and has received numerous industry awards for its innovation in both Web and XML Web services security technology. The Teros team will be added to Citrix's San Jose, CA.-based Application Networking Group to extend the technological leadership of the company's NetScaler® application delivery product line.

This acquisition further extends Citrix's leadership in application delivery solutions, products that enable companies to deliver all application types - client/server, desktop and Web - with the highest performance, lowest cost and best security possible. Delivering secure Web applications is particularly challenging because Web vulnerabilities are generally easy to exploit(1), and attacks cannot be detected by traditional security products. In addition, Web applications provide direct access to some of the most sensitive and valuable data in any enterprise, including financial records, credit card numbers and customer identity information, making them especially attractive targets for hackers. These trends have led to a dramatic spike in Web application attacks according to the FBI, with 95 percent of enterprises reporting more than 10 serious Web security incidents last year, up from just five percent in 2004(2).

The Teros solution is a great complement to Citrix's recently-acquired NetScaler product line. As the market leader in Web application delivery, the NetScaler solution provides customers with a single integrated solution that dramatically improves the performance, cost and security of mission-critical Web applications, including defenses against a wide range of application-layer threats such as denial of service and worm attacks. With more than 4,000 enterprise deployments, including the five largest sites on the Internet, the Citrix® NetScaler solution already provides secure Web application delivery for millions of users worldwide. Adding the Teros technology will further extend this lead, providing Citrix customers with the industry's broadest set of defenses against Web and XML Web services threats, and solidifying Citrix NetScaler as the most secure Web application delivery solution on the market.

"Web application attacks are the most serious threat to IT security infrastructures today, putting sensitive corporate information and confidential customer data at risk. In the wake of increasingly strict government regulations worldwide, protecting applications is no longer an option," said B.V. Jagadeesh, group vice president and general manager, Citrix. "Customers are increasingly looking to their application delivery vendors to secure against these emerging threats. Teros provides Citrix with state-of-the-art application security capabilities that further extend our leadership as the fastest, most cost-effective, most secure way to deliver Web applications."
