QualysGuard Data Security Model Achieves Highest Rating from Independent Auditors

Ernst & Young Accredits Qualys as SAS 70 Compliant @stake Penetration Tests Certify the Security of Customer Data

Infosecurity 2003, New York, NY — December 11, 2003 — Qualys™, Inc., the market leader of on-demand Network Security Audits and Vulnerability Management, today announced its QualysGuard® web service has passed a penetration test from @stake, awarding QualysGuard with its highest rating (“exceptional”) in data security. In addition to the @stake testing, QualysGuard has successfully completed an independent Statement on Auditing Standards No. 70 (SAS 70) Type I Service Audit performed by Ernst & Young, confirming that proper controls are in place to protect customer data.

The @stake testing of the QualysGuard web service occurred over the first and second quarter of 2003 and consisted of an in-depth security architecture review, aggressive penetration testing, application and user account security analysis, authorization and access control analysis, extended QualysGuard service analysis, and best practice-based network architecture evaluation. The results of the @stake testing concluded that the QualysGuard service complies with a wide range of best practices to protect customer data using secure data transmissions, a protected database, strong encryption standards, and sound architectural design to minimize any threats of attack.

“In our testing process, Qualys successfully protected against all of our attacks, exhibiting no security weaknesses that could be used to compromise the security of the QualysGuard service or its deployment environment,” said Chris Wysopal, Vice President of Research & Development for @stake, Inc.

In the SAS 70 certification, Ernst & Young examined the controls placed in operation at Qualys in accordance with the internationally-recognized standards developed by the American Institute of Certified Public Accountants. The SAS 70 accreditation means that Qualys has implemented controls that are suitably designed to achieve the specified control objectives and activities, affirming Qualys’ reputation as a trusted provider of network security audits and vulnerability management solutions.

The SAS70 audit is available upon request.
