Qualys CTO Named One of InfoWorld's 25 Most Influential CTOs for Second Year in a Row

Gerhard Eschelbeck Recognized for Innovative Contributions to the Security Industry in 2003

Redwood City, CA — January 27, 2004 — Qualys™, Inc., the market leader of on-demand Network Security Audits and Vulnerability Management, today announced Gerhard Eschelbeck, Qualys CTO and vice president of engineering, has been selected as one of InfoWorld’s “25 Most Influential CTOs of 2003” for the significant contributions he has made to the security industry. Eschelbeck is one of only two award winners who have been recognized two consecutive years for their leadership and accomplishments.

“Innovation does not occur in a vacuum,” said Steve Fox, InfoWorld editor in chief. “It is the result of vision, expertise, and applied creativity. This year’s CTO 25 award winners provided leadership to their companies and the industry during a difficult period, and they continue to lead during the recovery.”

In 2003, Eschelbeck published the industry’s first research on security vulnerabilities. “The Laws of Vulnerabilities” were derived from a statistical analysis of thousands of critical vulnerabilities collected on an aggregate basis from millions of scans performed across thousands of networks. From this research, Eschelbeck determined the laws that govern vulnerabilities’ life cycle and predict how likely they are to be exploited. Based on these Laws and real-time analysis of what is now the industry’s largest vulnerability dataset, Eschelbeck created the Top 10 critical vulnerability index known as the RV10. This index provides a measurement of the potential impact of new vulnerabilities as they are uncovered; thus allowing for an effective prioritization of remediation efforts.

As a result of widespread interest in his vulnerability research, Eschelbeck was invited to testify before Congress in September 2003. In addition to “The Laws of Vulnerabilities” research, Eschelbeck continued to contribute to the development of the SANS 20 and has led Qualys’ support of the SANS @RISK newsletter, a weekly newsletter to inform the community of the latest security threats. He is also a part of the Department of Homeland Security’s Task Force on Cyber Security Early Warning that is developing a method to disseminate warnings in a timely manner.

“Gerhard has the tremendous experience and responsibility of securing over 1,300 customer networks worldwide, including more than 150 Fortune 1000 companies. This requires a relentless commitment to understanding the changing landscape of security threats,” said Philippe Courtot, chairman and CEO of Qualys. “Gerhard has been the driving force and provided the vision that has allowed us to build a groundbreaking vulnerability management Web service. The Qualys solution allows companies of any size to take an inventory of their global network, assess their security risk, prioritize and audit remediation efforts in a continuous and automated way”.

Each year, InfoWorld honors IT executives who have shown leadership both inside and outside of their companies. Nominations are reviewed by the InfoWorld’s CTO Advisory Council, which makes recommendations to InfoWorld editors for final selection.
