Free Qualys Vulnerability Scan Available for the SANS Top-20 2005 Update

New vulnerabilities found in server-side applications and networking equipment can be identified at — Qualys CTO presents Top-20 at launch event at the DTI in Westminster, London

London — November 22, 2005 — Qualys, Inc., the leading provider of on demand vulnerability management and policy compliance solutions, today announced the availability of a free network scanning service to help companies find and eliminate vulnerabilities listed in the annual SANS Top-20 announced today. The SANS Top-20 is designed by the SANS Institute and security experts from industry and government to provide organisations with a prioritised list of newly discovered exposures to their networks. Qualys’ free scan for the SANS Top-20 is available at

In addition to identifying vulnerabilities in Windows and UNIX categories, this year’s Top-20 also includes Cross-Platform Applications and Networking Products. The change reflects the dynamic nature of the evolving threat landscape. The full SANS report can be found at

“The SANS Top-20 provides an invaluable tool for helping businesses prioritise their efforts in addressing security vulnerabilities. This year’s SANS Top-20 identified two growing areas of risk for organisations: increasing threats in client-side applications and critical vulnerabilities in networking equipment. These are issues that should be identified and addressed within organisations of every size,” said Gerhard Eschelbeck, CTO and VP of Engineering at Qualys. Eschelbeck, along with other experts in the community, provided contributions to the development of the SANS Top-20 list and presented the Top-20 at the launch event at the DTI in Westminster.

The shift from server-side to client-side vulnerabilities was also a significant finding in the latest “Laws of Vulnerabilities” research published by Eschelbeck last week. According to the research, more than 60 percent of new critical vulnerabilities occur in client applications. Client-side vulnerabilities require a user to take action, such as visiting a malicious website or opening an infected email attachment. The research can be found at

Qualys’ on demand model provides customers with immediate vulnerability updates, such as the Top-20 listing, without the need for installing software or building out additional infrastructure. In addition to the free scan, the QualysGuard® service detects new exposures in the SANS Top-20.
