NEW YORK--(BUSINESS WIRE)--August 15, 2001

Leading Network Infrastructure Consulting Firm Offers Insights

and Proven Solutions Critical to Network Security

With information security threats on the rise, discovering corporate network vulnerabilities before hackers do has become critical.

To help IT professionals and top executives guard against attack, Predictive Systems (Nasdaq: PRDS), a leading network infrastructure and information security consulting firm, will host: How Secure Is Your Network, Really? - a free, live Webcast that will offer participants expert advice on how ethical hacking tests can uncover and address potential security vulnerabilities. This Webcast will take place on Wednesday, August 22, 2001, at 12:00 PM EST.

As more and more companies fall prey to viruses, hackers, and various cyber-attacks, the need for companies to test their own security has become increasingly paramount. Ethical hacking allows a company to test its network for vulnerabilities that might be exploited by an intruder. Hosted by Anish Bhimani, Predictive Systems' Chief Technology Officer, Chris O'Ferrell, Director of Ethical Hacking, Peter Browne, VP of Predictive Systems' Global Integrity Information Security practice, and Ed Skoudis, Vice President of Security Strategy, the Webcast will answer security questions such as:

      --  Why perform an ethical hacking test if my company's firewall
        and servers are secure?

      --  Should I prepare my security team?

      --  What information should I share with my testing team?

      --  Could an ethical hacking test cause my systems to crash?

      --  Who should conduct the test: an in-house team, or a third
        party?
