History Qualys has been described as "one of the earliest software-as-a-service security vendors." Philippe Courtot first invested in the company in 1999. He became CEO and board chair in 2001. In the announcement of the second round of financing, Courtot described Qualys as addressing a "mounting need for automatic detection of network vulnerabilities." The company launched QualysGuard in 2000, making Qualys one of the first entrants in the vulnerability management market. This software could automatically scan corporate LANs for vulnerabilities and search for an available patch. The company subsequently added compliance, malware detection, and web application scanning to its platform. Qualys went public on the Nasdaq under the stock ticker QLYS on September 28, 2012, raising net proceeds of $87.5 million. Qualys then launched its Cloud Platform and lightweight cloud agent to continuously assess the security and compliance of organizations' global IT infrastructure and applications. The new Cloud Platform helped organizations assess and address the security and compliance of their IT assets in real-time, whether on-premises, cloud-based or mobile.
