Tenable Holdings, the exposure management company, has made permanent the appointment of Steve Vintz and Mark Thurmond as co-Chief Executive Officers, a decision that concludes a succession process begun after the unexpected death of long-serving CEO Amit Yoran in January 2025. The Board of Directors unanimously confirmed their appointments on April 16, a move that reflects confidence in the executives' leadership during an interim period that saw the company expand its customer footprint and complete a strategic acquisition. Vintz, who has served as Chief Financial Officer since 2014, will oversee product, cybersecurity, corporate development and general administrative functions. Thurmond, Chief Operating Officer since 2020, will manage go-to-market functions including sales, professional services, technical support, marketing and customer success. Both executives are expected to join Tenable's board immediately following the company's annual shareholder meeting scheduled for May 14, 2025.
The appointment concludes an extensive board search process that considered both internal and external candidates before determining that Vintz and Thurmond were best positioned to lead the company forward. Art Coviello, who assumed the chairmanship following Yoran's passing, praised the executives' collaborative leadership style and customer-focused approach. The board's decision was particularly noteworthy given that Yoran, who had led Tenable since 2016 and taken the company public in 2018, died unexpectedly on January 3, 2025, after a brief cancer battle. Vintz and Thurmond assumed interim co-CEO responsibilities on December 5, 2024, when Yoran took medical leave, demonstrating what the board characterized as significant operational and strategic momentum during their temporary tenure.
Vintz brings more than 25 years of financial and operational experience in the technology sector. He joined Tenable in 2014 and played a pivotal role in shepherding the company through its 2015 Series B funding round, at that time the largest capital raise for a private cybersecurity company, as well as its 2018 initial public offering, which ranked among the largest for a U.S.-listed security company. Before Tenable, Vintz served from 2001 to 2014 as executive vice president and chief financial officer of Vocus, a publicly traded public relations software firm, where he oversaw 40 consecutive quarters of revenue growth and managed numerous acquisitions. Earlier in his career, Vintz held a vice presidency at Snyder Communications, where he played a lead role in more than 45 acquisitions and oversaw the company's expansion from $86 million to nearly $1 billion in revenue. He also spent time with Ernst & Young's entrepreneurial services group. Vintz holds a bachelor's degree in business administration from Loyola University and is a certified public accountant.
Thurmond, an accomplished go-to-market executive with deep experience in sales and operations, joined Tenable as Chief Operating Officer in February 2020 after spending two and a half years as COO of Turbonomic, where he aligned global operations to support hybrid cloud adoption. His prior roles included Executive Vice President of worldwide sales and services at Qlik Technologies and multiple leadership positions at divisions of Dell EMC, including Senior Vice President of worldwide sales at VCE and RSA. He earned an undergraduate degree in psychology from Hofstra University. Under Thurmond's leadership at Tenable, the company has expanded its customer base and driven strong adoption of its flagship Tenable One Exposure Management platform.
Tenable, founded in 2002 by Ron Gula, Jack Huffard and Renaud Deraison, has evolved into a market leader in exposure management and vulnerability management solutions. The Columbia, Maryland-based company serves approximately 44,000 customers globally, including more than 65 percent of the Fortune 500 and 50 percent of the Global 2000. The company's platform provides comprehensive visibility across IT, cloud, operational technology and web application environments. During the interim leadership period, Tenable completed the strategic acquisition of Vulcan Cyber and expanded its cloud security offerings, developments that position the company for what management characterizes as its next growth phase.
The elevation of Vintz and Thurmond to permanent co-CEO status represents a departure from traditional single-CEO governance, a structure that underscores the board's belief in shared leadership. The decision implicitly reflects confidence that the split between product and financial strategy (Vintz) and commercial execution (Thurmond) can function effectively at the highest levels of the company. Industry observers might view the permanent nature of the co-CEO arrangement as a sign that the board favors continuity and complementary skill sets over the search for a single external candidate. The appointment also comes as Tenable recently achieved recognition as a Leader in Gartner's inaugural 2025 Magic Quadrant for Exposure Assessment Platforms, a validation of the strategic direction Vintz and Thurmond have guided during an otherwise challenging transition period.
