Business Overview and History
Tenable Holdings, Inc. (NASDAQ:TENB) is a leading provider of exposure management solutions, playing a crucial role in the rapidly expanding cybersecurity market. With its innovative Tenable One platform, the company is helping organizations across various industries address the growing complexities of the modern attack surface, from IT infrastructure to cloud environments and critical systems.
Tenable was founded in 2002 by three cybersecurity veterans, with the goal of revolutionizing the way organizations manage and mitigate cyber risks. The company's flagship product, Nessus, was initially introduced in 1998 and has since become one of the most widely deployed vulnerability assessment solutions in the industry.
Over the years, Tenable expanded its product offerings beyond Nessus, developing a suite of enterprise security solutions. In 2012, the company launched its Tenable Network Security product, which provided organizations with a risk-based view of their traditional and modern attack surfaces. This product laid the foundation for Tenable's transition from a vulnerability management specialist to a broader exposure management platform provider.
Tenable faced some challenges in its early years, as it navigated the competitive cybersecurity landscape and worked to diversify its product portfolio. However, the company's focus on innovation and its ability to anticipate evolving customer needs helped it overcome these obstacles. In 2018, Tenable went public on the Nasdaq stock exchange, raising $251 million in its initial public offering.
Following its IPO, Tenable continued to strengthen its product capabilities through both organic development and strategic acquisitions. In 2023, the company acquired Ermetic, a cloud infrastructure entitlement management provider, and in 2024, it acquired Eureka Security, a data security posture management solution. These acquisitions expanded Tenable's offerings in cloud security and helped the company deliver a more comprehensive exposure management platform to its customers.
Today, Tenable operates in over 170 countries and serves a diverse customer base that includes approximately 65% of the Fortune 500 and 50% of the Global 2000. The company's success has been driven by its commitment to innovation, its deep understanding of the evolving cybersecurity landscape, and its ability to provide its customers with the tools and insights they need to navigate the complex threat environment.

Growth Drivers and Strategic Initiatives
Tenable's growth strategy is centered around three key pillars: expanding its customer base, deepening existing customer relationships, and driving innovation within its Tenable One platform.
The company has been successful in acquiring new enterprise platform customers, adding 485 new customers in 2024. Additionally, Tenable has been able to expand its footprint within its existing customer base, as evidenced by its strong dollar-based net retention rate of 108% in 2024.
One of the company's key strategic initiatives is the expansion of its Tenable One platform, which is designed to provide a comprehensive view of cyber risk across an organization's entire attack surface. In 2024, Tenable One accounted for 40% of the company's new business sales, highlighting the strong demand for this solution.
To further enhance its Tenable One offering, Tenable announced the acquisition of Vulcan Cyber in February 2025. Vulcan Cyber's capabilities will enable Tenable to provide more robust data aggregation, prioritization, and remediation workflows, helping customers better manage their cyber exposure. This acquisition is expected to contribute an additional 50 basis points of growth to calculated current billings and revenue for the full year 2025.

Competitive Landscape and Risks
Tenable operates in a highly competitive cybersecurity market, with a diverse set of competitors ranging from specialized vulnerability management vendors to larger, diversified security software providers. The company's ability to maintain its competitive edge will depend on its continued investment in product innovation, its go-to-market strategy, and its ability to effectively address the evolving needs of its customers.
Key risks facing Tenable include the potential for increased competition, the challenge of keeping pace with rapidly changing technology and security threats, and the ongoing management of its global operations and talent acquisition/retention efforts. Additionally, the company is subject to various regulatory requirements, particularly around data privacy and security, which could impact its operations and financial performance.
Industry Trends and Market Outlook
The cybersecurity market is projected to grow at a compound annual growth rate (CAGR) of 12.9% from 2025 to 2030. This growth is primarily driven by increasing cyber threats and rapid digital transformation across industries. Tenable's focus on cloud-based offerings, identity security, and operational technology security solutions positions it well to address the evolving cybersecurity challenges faced by organizations as they navigate the expanding attack surface and increasing sophistication of cyber threats.
Recent Developments and Leadership Changes
In January 2025, Tenable's co-founder and former CEO, Amit Yoran, passed away. The board is currently conducting a search for a new CEO, with Steve Vintz and Mark Thurmond serving as interim co-CEOs. This leadership transition represents a significant change for the company, but Tenable's strong management team and established market position should help ensure continuity in its operations and strategic direction.
Financial Guidance and Outlook
For the first quarter of 2025, Tenable expects revenue between $232 million to $234 million, non-GAAP income from operations between $42 million to $44 million, and non-GAAP diluted earnings per share between $0.28 to $0.30.
For the full year 2025, the company anticipates calculated current billings between $1.4 billion to $1.5 billion, revenue between $971 million to $981 million, and non-GAAP diluted earnings per share between $1.52 to $1.60. Tenable also expects to generate unlevered free cash flow between $285 million to $295 million for the year.
It's worth noting that this guidance excludes the impact of the pending Vulcan Cyber acquisition, which is expected to close shortly and contribute an additional 50 basis points of growth to calculated current billings and revenue for the full year 2025.
Conclusion
Tenable's strong financial performance, innovative product offerings, and strategic initiatives position the company well to capitalize on the significant growth opportunities in the cybersecurity market. The company's focus on exposure management and its ongoing efforts to expand the capabilities of its Tenable One platform are expected to drive continued revenue growth and profitability improvements.
While the company faces various risks and competitive challenges, Tenable's proven track record, experienced management team, and robust financial position suggest that it is well-equipped to navigate the evolving cybersecurity landscape and deliver long-term value for its shareholders.
