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.

While we enjoy listening to the management’s commentary, our favorite part of earnings calls is the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.
Our top 5 analyst questions from Tenable’s Q3 earnings call
- Michael Cikos (Needham & Company) asked about the breakdown between new and existing customers adopting Tenable One. Co-CEO Mark Thurmond explained that both new logos and conversions from legacy VM customers contributed significantly to platform growth.
- Rudy Kessinger (D.A. Davidson) pressed on whether increased vulnerability discoveries would drive more frequent scanning and affect pricing. Co-CEO Stephen Vintz said Tenable is evolving pricing to blend asset and usage models, aiming to capture value from higher prompt volumes without discouraging use.
- Jonathan Ho (William Blair) inquired about the drivers behind growth, seeking clarity on expansion versus upsell versus new product sales. Thurmond emphasized balance, noting significant expansion in the installed base and strong new logo additions for Tenable One.
- Roger Boyd (UBS) questioned the impact of high-profile vulnerabilities like PHP2Shell compared to past events such as Log4j. Vintz responded that while it’s too early to quantify, early signs suggest a durable tailwind for exposure management demand.
- William Bellamy (Jefferies) asked about traction in operational technology (OT) security, especially in federal and critical infrastructure markets. Thurmond confirmed strong adoption, highlighting notable wins in both federal and state/local sectors.
