Thanks, Erin. We delivered excellent results in the third quarter. On our last call, we discussed the increasing momentum in our business. And this quarter, we are very pleased to see that momentum start to translate into acceleration. What excites me most are the leading indicators, which show inflection and signal durability of growth ahead. Our net dollar expansion rate accelerated to 107%, up from 106% in Q2, which is the first time in over 4 years we've seen acceleration in the expansion rate for 2 consecutive quarters. Tenable One reached a record 59% of new business, up from 50% in Q2. Average Tenable One deal sizes year-over-year rose for the second straight quarter, driven by the pricing and packaging we introduced earlier this year. And CCB accelerated to 9% growth in the third quarter. These results demonstrate that we're delivering what customers need most, which is the ability to see and act on risk across the entire environment at the speed this new era demands and no force is shaping that more than AI. Before we dive into the product updates for the quarter, I want to touch upon PHP2Shell, the critical vulnerability disclosed last week. Earlier this year, we said AI would surface more vulnerabilities and exposures faster. That's playing out now. PHP runs nearly everywhere in the enterprise, including web applications, cloud workloads, containers and legacy systems. The vulnerability is the headline, but the risk goes beyond the vulnerabilities themselves. Organizations need to find affected instances, including those they may not know about and understand how they connect to misconfigurations, credentials and critical systems. Following PHP2Shell disclosure, customers turned to Hexa, and we've seen prompt volume increase dramatically by as much as 5x. Beyond Hexa, customers have been turning to Tenable as a trusted partner during this critical time, and we've been working closely with them to ensure they can leverage the full power of the platform to reduce their exposure. PHP is a real-time example of a broader shift in the market, and that is AI is reshaping the attack surface faster than most organizations can respond. This is more than a moment. It's a mandate and a structural shift for enterprises. As a result, every enterprise is adopting AI and every model, every agent, every MCP server they deploy creates new exposures. Meanwhile, attackers are using frontier AI to find weaknesses faster, and we're now witnessing the early automation of exploit development. The risk extends well beyond CVEs, and we believe this is a powerful demand catalyst for exposure management and a significant growth opportunity for Tenable. As I outlined last quarter, winning in exposure management requires 3 capabilities: understanding every exposure, prioritizing what matters most and acting with speed and confidence to reduce risk. As frontier models become widely available, intelligence itself becomes abundant. The differentiator is putting it to work safely. That's the Tenable advantage, decades of exposure intelligence, deep visibility across the attack surface and an AI harness that keeps agents acting safely with human oversight and an audit trail. In this quarter, we significantly expanded what that platform can do across all 3. In September, we announced that we're bringing Anthropic's Claude Mythos into Tenable One. This expands our partnership with Anthropic beyond Project Glasswing. Our first capability powered by Claude Mythos, Tenable One Adversary View, lets security teams see their environment through the eyes of an attacker. Every time Tenable assesses the system, we learn what's running on it, how it's configured, who can access it and what it connects to. Adversary View applies Mythos to that telemetry to reason like an attacker. It sees how low signal exposures can be chained together to reach critical systems, then recommends the specific fixes that break those chains. It's a compelling example of how we're turning frontier AI into differentiated capabilities designed to keep customers ahead of emerging threats. We also expanded Tenable Hexa AI, our agentic engine for Tenable One. Hexa now works as a coordinated fleet of agents that continuously identify critical exposures, orchestrate remediation and verify fixes even when security teams are offline. Since June, Hexa has evaluated more than 2 billion assets and findings, which enable Hexa users to resolve more critical and high-severity vulnerability detections per month than match peers and patch actively exploited vulnerabilities faster. Tenable Hexa AI saves security practitioners time and resources, enabling them to reclaim analyst capacity, maintain always-on defense and dramatically reduce mean time to remediation. Importantly, Hexa is model agnostic. It works with leading frontier and open weight models, so customers benefit as those models improve, while our harness keeps every action grounded in validated exposure data. Finally, we launched the CyberAgents Exchange, the industry's first open source vendor-agnostic registry for cybersecurity AI agents and skills. Its AI inspector pairs OpenAI's ChatGPT cyber models with Tenable researchers to vet community-built components before enterprises deploy them, putting Tenable's data and expertise at the center of trusted agentic security. Cybersecurity used to be about detecting and triaging threats. Today, it determines how fast the world can adopt AI. As a result, security is no longer a line item inside IT. It's becoming its own business function with a budget tied to business risk and growth. We believe Tenable is uniquely positioned to lead in this AI era, and the momentum we are seeing today gives us confidence in the durability of growth ahead. With that said, Mark will now walk you through how the momentum we are seeing is showing up with our customers. Mark?
