Tenable Holdings, Inc.
A cybersecurity company that helps organizations find and fix weaknesses in their computer networks before attackers can exploit them. Its best-known product is Nessus, a vulnerability scanner created in 1998 by co-founder Renaud Deraison when he was just 17, which became an industry standard. The company was founded in 2002 and named "Tenable" for the word's meaning — capable of being held and defended — a fitting motto for a business built on keeping networks secure.
