Qualys Anounces Agreement with VeriSign to Offer QualysGuard™ Online Network Vulnerability Auditing Service

San Jose, Calif. — May 22, 2001 — Qualys, Inc., a leading provider of enterprise network vulnerability assessment and monitoring solutions, today announced that VeriSign, Inc. (NASDAQ: VRSN), the leading provider of Internet trust services, is making the QualysGuard™ online network vulnerability auditing service available to its digital certificate clientele on a subscription basis.

Completely Web-based, with no special software or hardware required, the QualysGuard service automatically scans computer networks over the Internet for security exposures, thus enabling VeriSign customers to proactively and cost-effectively defend themselves against intrusion.

“We’re offering QualysGuard as an important added-value service along with our digital certificate services,” said Ben Golub, Vice-President, Web Site Trust Services, VeriSign. “VeriSign customers can use the QualysGuard service at any time and from any location to visualize their network vulnerabilities and accurately assess their security risks in real-time”.

The QualysGuard service quickly audits any sized network, graphically maps and describes security risks, and suggests possible solutions. More than 900 vulnerability tests are performed automatically with audit results delivered to a private Web page for secure customer viewing. Customers benefit from an “intruder’s-eye view” of their security exposures, a worldwide auditing capability, and a constantly growing knowledge base that enables users to keep abreast of the newest security vulnerabilities.

“It is very significant that VeriSign is using the remote online security auditing space in this manner,” said Philippe Courtot, Chairman and CEO of Qualys. “Until QualysGuard, auditing a network for security holes was an expensive and time-consuming proposition, requiring specialized software and equipment. In offering QualysGuard, VeriSign is leveraging the same convenient channel they use for delivering certificates to deliver an additional valuable security service at a very reasonable cost to its customers.”

Effective immediately through the VeriSign Web site, customers can choose between two separate introductory pricing offers and may also choose to purchase unlimited yearly subscriptions.
