Tenable is a cybersecurity company founded in 2002 and headquartered in Columbia, Maryland, that pioneered the vulnerability management category and remains its global leader. The company was founded by Ron Gula and Jack Huffard around the Nessus vulnerability scanner, one of the most widely deployed security tools in the world, with a mission to help organizations understand and reduce their cyber exposure across their entire attack surface. Tenable's core conviction is that organizations cannot defend what they cannot see — and that comprehensive, continuous visibility into vulnerabilities is the prerequisite to effective security.\n\nTenable's platform portfolio includes Tenable.io (cloud-native vulnerability management), Tenable.sc (on-premises), Tenable OT Security (operational technology), Tenable Web App Scanning, Lumin (exposure-based risk scoring), and the Tenable One exposure management platform. The company serves enterprise and government customers globally with a product suite that covers cloud workloads, on-premises infrastructure, operational technology, and web applications. In February 2025, Tenable completed the $148 million acquisition of Vulcan Cyber, a risk-based vulnerability prioritization platform, expanding its capabilities in correlating vulnerability data with threat intelligence and business context.\n\nTenable reported trailing twelve-month revenue of $974.60 million as of 2025, up 11% year over year, and was named the number one worldwide vulnerability management vendor by IDC in 2024. The company trades on Nasdaq under the ticker TENB and competes against Qualys, Rapid7, and a growing set of cloud-native exposure management entrants. Its Nessus heritage, market leadership validation from IDC, and strategic expansion into broader exposure management through Tenable One and the Vulcan Cyber acquisition position it as the reference platform for enterprise vulnerability and exposure management.
Armonk NY hybrid cloud and enterprise AI (NYSE: IBM) at $62.8B revenue; $6B+ generative AI bookings, record $12.7B free cash flow 2024, DataStax acquisition for watsonx vector database competing with Microsoft Azure for enterprise AI.
International Business Machines Corporation (IBM) is an Armonk, New York-based global technology and consulting company — publicly traded on the New York Stock Exchange (NYSE: IBM) as an S&P 500 component — providing hybrid cloud infrastructure, artificial intelligence software, and enterprise IT consulting through approximately 270,300 employees in 170 countries with $62.8 billion in annual revenue. Founded on June 16, 1911, as Computing-Tabulating-Recording Company through a merger orchestrated by financier Charles Ranlett Flint, renamed IBM in 1924 under Thomas Watson Sr., IBM has undergone multiple strategic transformations over its 110+ year history: building the System/360 mainframe platform (1964), launching the IBM PC (1981), selling the PC division to Lenovo (2005, $1.75B), and completing the $34 billion Red Hat acquisition (2019) that repositioned IBM as a hybrid cloud platform company. CEO Arvind Krishna (appointed April 2020) has focused IBM's strategy on three areas: hybrid cloud (powered by Red Hat OpenShift, the enterprise Kubernetes platform), AI (the watsonx platform for enterprise AI model development and deployment), and enterprise consulting. Under Krishna, IBM recorded $12.7 billion in free cash flow in 2024 (a company record), surpassed $6 billion in generative AI bookings since June 2023, and saw the stock price double — trading at all-time highs through 2024-2025. IBM announced the DataStax acquisition in 2025 to deepen watsonx's data layer with AstraDB (vector database for AI applications), DataStax Enterprise (Apache Cassandra), and Langflow (low-code AI agent development).
