Q3 2025 Financial Highlights: Exceeding Expectations
Tenable’s financial results for the third quarter ended September 30, 2025, painted a picture of strong execution and promising growth across key metrics:

- Calculated Current Billings (CCB): $267.5 million, representing a 7.7% year-over-year increase.

These figures demonstrate Tenable’s ability to not only meet but exceed its financial guidance, providing a strong foundation for the remainder of the fiscal year.
The Shift from Firefighting to Fireproofing: Exposure Management Takes Center Stage
A central theme of the earnings call was the fundamental paradigm shift occurring in cybersecurity. Co-CEO Stephen A. Vintz powerfully articulated this, stating, “AI is dramatically reshaping the threat landscape as attacks have become faster, more automated, and more sophisticated, exposing the limits of traditional reactive defenses.” This calls for a move from “firefighting” (detecting breaches) to “fireproofing” (preemptive security).
Historically, over 95% of cybersecurity spending has been on post-breach technologies. However, this mix is rapidly changing, with exposure management (EM) emerging as a critical budget priority. Tenable’s Tenable One platform is at the forefront of this transformation, offering unified visibility, intelligence, and actionable insights across the entire attack surface—including cloud, IT, OT (Operational Technology), and identity domains.
The market is clearly taking notice, with Tenable being recognized as a leader in exposure management by prominent industry analysts. In July, Tenable was named a leader in the Forrester Wave for unified vulnerability management solutions, and in August, it received recognition as a leader in the IDC MarketScape for Exposure Management Platforms. Furthermore, IDC reported Tenable ranked number one in its latest market share report in September, as noted by the Tenable official press release. This external validation underscores the company’s strong competitive position.
AI and Innovation: Securing the Future
Tenable’s commitment to innovation is evident in its substantial R&D investments, which are up over 20% year-to-date in 2025. These investments are concentrated on enhancing Tenable One and integrating advanced AI risk management features. A significant development in Q3 was the launch of Tenable AI Exposure, a solution designed to give CISOs unprecedented visibility and control over generative AI risks within their environments.
This innovation allows organizations to:
- Discover AI usage across their infrastructure.
- Understand the impact of AI on their attack surface.
- Identify potential exposures from AI-enabled applications, code, and user behavior.
Moreover, Tenable has surpassed 300 validated integrations on the Tenable One platform, reinforcing its position as an open and interconnected exposure management solution. These integrations are crucial for breaking down silos across various security domains, from vulnerability management to identity and OT operations, enabling customers to unify data, apply context, and orchestrate faster, more coordinated responses.
Customer Momentum and Strategic Wins
The company’s strategic focus is clearly resonating with customers. Tenable added 437 new enterprise platform customers in Q3, a 13% increase year-over-year, with half of these new customers adopting exposure solutions directly. Tenable One accounted for 40% of new business in the quarter, with over 3,000 of Tenable’s 18,000 enterprise customers now on the platform as of September 30, 2025.
Mark Thurmond highlighted several key customer wins, including:
- A major new logo in global commercial real estate, displacing a top cloud security provider and an incumbent vulnerability management player to consolidate onto Tenable One.
- A significant win with a national electric utility provider in EMEA, leveraging Tenable’s ability to integrate IT and OT environments for critical infrastructure protection.
- A six-figure expansion with a leading technology provider serving the public sector, upgrading from a standalone cloud product to the comprehensive Tenable One platform.
These wins underscore a growing trend of customers signing longer-term contracts due to the strategic roadmap clarity offered by Tenable One. As Mark Thurmond explained, “customers [are] willing to sign up for long term contracts due to strategic roadmap clarity.”
Future Outlook and Investor Confidence
For the remainder of 2025, Tenable has raised its full-year guidance, reflecting incremental optimism. The company now projects full-year revenue between $988 million and $992 million (10% year-over-year growth at the midpoint) and non-GAAP operating income between $211 million and $215 million (21.5% non-GAAP operating margin). This demonstrates a clear commitment to balancing top-line growth with a steady increase in profitability.
New CFO Matt Brown, welcomed warmly by the investment community, emphasized the underlying strength of Tenable’s business model. With 95% of revenue being recurring, there’s a significant opportunity for continued growth and increased operational leverage. The focus remains on driving customers to Tenable One, which is seen as the catalyst for long-term expansion and monetization of new AI risk controls and third-party asset types in upcoming quarters.
The strong performance in the US federal sector, which was in line with expectations despite seasonal highs and potential government funding uncertainties, further solidifies Tenable’s reliability across diverse markets. As the company continues to refine its exposure management maturity model and engage with its leadership council of forward-thinking CISOs, Tenable is not just selling a product; it’s guiding a fundamental shift in how organizations approach cybersecurity in the AI era.
