History

Tenable was founded in 2002 as Tenable Network Security, Inc. by Ron Gula, Jack Huffard, and Renaud Deraison.[2] In 2005, Nessus became proprietary software, rather than open-source software, to generate income for the company.[3]

In September 2012, Tenable received $50 million in series A round funding from Accel Partners.[4] Also that month, the company entered into a partnership to provide cybersecurity services for the United States Intelligence Community.[5] In 2015, Tenable received $250 million in a series B round led by Insight Partners.[6] In 2017, the company was renamed Tenable, Inc.[1] In July 2018, the company became a public company via an initial public offering.[7]
