The Philadelphia Stock Exchange Inc. is using intrusion-prevention software from V-Secure Technologies Inc. as an electronic watchdog to keep its growing number of Web applications safe. "It's the first thing Web-site visitors encounter," says Bill Morgan, CIO at the stock exchange. "It helps to make sure there are no unauthorized accesses, that nothing out of line gets through." The V-100 protects the stock exchange's systems from denial-of-service attacks and IP-spoofing attacks. It also can block attacking Internet addresses and enforce rules that determine which users can access which applications.

For many, intrusion-prevention systems are a necessary tool in the fight against growing threats and attacks, and the technology has proven its mettle. "We've only had one machine get hit since we've bought this," says Daniels Trading's Swanson. "That's because we didn't install it on that system."
