Redwood City, Calif. - September 7, 2010 - Qualys®, Inc., the leading provider of on demand IT security risk and compliance management solutions, announced today that it was ranked number 2,382 by Inc. magazine in its fourth annual Inc. 5,000 – an exclusive ranking of the nation’s fastest growing companies across all industries.
