StockStory’s take
Tenable’s third quarter was marked by strong customer momentum and a notable increase in adoption of its core Tenable One platform. Management attributed the quarter’s performance to rapid customer migration from standalone vulnerability management to the Tenable One platform, with Co-CEO Mark Thurmond emphasizing, “Q3 was our best quarter ever for Tenable One new logos, with more than half of them landing on our Advanced package.” The company also highlighted the impact of emerging AI-driven threats, which helped drive demand for its advanced exposure management solutions.
Looking forward, Tenable’s raised guidance is shaped by accelerating interest in AI-powered cybersecurity and expansion in key markets such as federal and critical infrastructure. Management pointed to continued investment in product innovation, especially with Hexa AI and new partnerships with AI providers, as the primary drivers of future growth. CFO Matt Brown noted, “We are raising our full year outlook, reflecting the growing momentum we’re seeing in the business,” while also cautioning that revenue benefits from major vulnerability events may take time to materialize given the evolving nature of customer adoption cycles.
Key insights from management’s remarks
Management credited product innovation and rapid customer adoption of Tenable One for driving platform expansion, while also acknowledging the accelerating threat landscape as a catalyst for future demand.
- Tenable One momentum: Customer migration to Tenable One accelerated, with 59% of new business coming from the unified platform. Management described this as a function of both new customer wins and strong conversion from existing vulnerability management (VM) customers, with average deal sizes rising as clients consolidated security tools.
- Hexa AI adoption: The company’s Hexa AI, an autonomous agent that identifies and remediates exposures, saw a sharp increase in usage—particularly after the PHP2Shell vulnerability disclosure. Thurmond stated that “customers using Hexa resolve 2 to 3x more critical exposures” than peers, helping security teams automate complex tasks and expand coverage.
- Pricing and packaging evolution: Tenable’s updated pricing model, combining asset-based and usage-based components, has supported higher average selling prices and improved expansion rates. This approach aims to lower adoption barriers for new customers while capturing greater value from usage-intensive clients, especially as AI-driven threats increase scan frequency and remediation needs.
- Competitive differentiation: Management cited competitive wins over both legacy and endpoint-focused security vendors, emphasizing Tenable One’s breadth of asset coverage, advanced prioritization, and accuracy. The ability to integrate multiple asset types and remediate attack paths was highlighted as a key differentiator.
- Federal and critical infrastructure traction: The company reported strong results in the federal sector, benefiting from new AI security mandates and increased adoption within state and local government, especially for operational technology (OT) security in critical infrastructure. Participation in government-led cybersecurity initiatives was seen as a potential tailwind for public sector growth.
Drivers of future performance
Tenable’s future guidance rests on continued platform adoption, expanded AI capabilities, and public sector demand, amid an evolving cybersecurity landscape.
- AI-driven exposure management: Management expects AI-enabled threats to further expand the attack surface, prompting greater enterprise adoption of Tenable One and Hexa AI. The company believes its agentic security and orchestration features will drive platform upgrades and higher customer spend, particularly as organizations seek to proactively manage complex exposures.
- Federal and critical infrastructure expansion: Recent U.S. federal AI security policies and heightened attention to critical infrastructure vulnerabilities are projected to sustain demand in public sector markets. Leadership expects this policy environment to act as a durable tailwind, with cybersecurity budgets remaining solid regardless of political changes.
- Evolving pricing and usage model: Tenable’s hybrid pricing—combining asset-based and usage elements—positions the company to capture increased value as customers run more frequent scans and remediation cycles in response to AI-driven vulnerabilities. This model is expected to support margin stability, with add-on sales mitigating potential gross margin pressure from increased Hexa usage.
Catalysts in upcoming quarters
In upcoming quarters, the StockStory team will be watching (1) continued momentum in Tenable One adoption and upsell activity, (2) the rate of Hexa AI usage growth and its impact on customer productivity and expansion, and (3) execution in the federal and critical infrastructure segments, especially as new security mandates take effect. Ongoing developments in pricing models and the competitive landscape will also be key signposts.
Tenable currently trades at $46.43, down from $48.72 just before the earnings. Is the company at an inflection point that warrants a buy or sell? See for yourself in our full research report (it’s free).
