Thank you, Blair, and welcome to our fourth quarter earnings call. As threat actors continue to compress time-to-exploit, we believe the next phase of pre-breach risk management will be defined by an agentic AI-driven risk fabric with out-of-the-box business quantification, automated remediation to respond to the speed of these threats. Against that backdrop, we continued to execute well in Q4, demonstrated by another quarter of strong revenue growth and profitability. In my conversations with hundreds of CIOs and CISOs as well as security leaders from many of the world's largest and most innovative organizations, one message has remained consistently clear. Reducing cyber risk isn't about detecting more exposures. It's about operationalizing a cyber risk management program that aligns spend with risk tolerance. In doing so, CISOs are increasingly prioritizing the unification of fragmented security stack into a centralized risk fabric, one that serves as a credible alternative to single-vendor platforms by bringing diverse risk vectors into a prioritized, measurable view of risk that their teams can confidently communicate and remediate at machine speed. That message was further amplified at our recently concluded ROCon conference in Mumbai, with attendance up over 30% from last year's event as we again broadened the agenda to include a business track. And with the element of AI, which is democratizing cybercrime and enabling adversaries to operate with unprecedented speed and sophistication, this need is only intensifying. As a result, we believe that the future of pre-breach risk management belongs to vendor-agnostic agentic AI-powered solutions that continuously predict, assess, confirm, quantify, prioritize and remediate risks across on-prem and multi-cloud environments. Over the past year, we continued to execute relentlessly towards this vision, delivering meaningful platform innovation to help customers reduce risk faster, operate more efficiently and stay ahead of an increasingly dynamic landscape. Accordingly, in 2025, we broadly expanded the Qualys ETM platform to third-party data and launched a powerful new orchestration layer that unifies Qualys and non-Qualys findings, applies our industry-leading threat intelligence and delivers a business-contextual quantified view of risk with built-in prioritization and automated remediation. Building on this foundation, we introduced an agentic AI risk fabric that assesses and normalizes diverse internal and external data sources, applications and machines. We expanded -- we extended these capabilities with the first-of-a-kind agentic AI risk management marketplace, enabling security and IT teams to quickly augment their existing workforce with highly specialized autonomous experts that significantly reduce time to remediation, increase accuracy and reduce costs. To further close security gaps, we again organically enhanced ETM with a natively integrated Identity Security Posture Management solution at a time when identities have become part of the new AI perimeter. And further flexing the power of our platform, we are now confirming exploits before customers are compromised. While traditional Continuous Threat Exposure Management solutions rely on a theoretical risk score and ignore mitigating security controls, ETM takes a fundamentally different approach. On a single platform, it uniquely detects vulnerabilities, validates exploitability, applies remediation and revalidates exploit using Agent Val, agentic AI workflow. The net result is that Qualys is redefining how organizations manage pre-breach risk management. While competitors continue to focus on detecting vulnerabilities or mapping theoretical exposures, Qualys has moved decisively beyond that model. We are pioneering the first agentic AI-native Risk Operations Center, ROC, a new category in cybersecurity designed to centralize an organization's response to threats spanning exploit confirmation to autonomous remediation. Powered by our ETM solution, the ROC represents a fundamental diversion from traditional CTEM tools. Competitors can point to exposures. They can't quantify cyber risk in dollar terms that matters most to the business, and they cannot adequately fix them. ETM fills that gap. This is what sets Qualys apart. We don't stop at detection and non-quantifiable prioritization. We natively integrate CTEM, exploit confirmation, risk quantification and remediation operations into a single AI-powered workflow, leveraging both Qualys and non-Qualys data sources. In doing so, our architecture orchestrates and implements a perception-reasoning-action loop, enabling autonomous agents to collect real-time telemetry, reason through risk signals, plan response workflows and execute actions. This enables organizations to holistically predict emerging risks across infrastructure, cloud, application security, IoT and identities, safely confirm probable exploits, prioritize threats based on business impact, remediate through patching or other compensating controls and verify the effectiveness of the remediated tactic. This end-to-end vendor-neutral approach is catalyzing a paradigm shift in pre-breach cyber risk management, where customers aren't just seeing their risk holistically across the risk stack. They're validating it, quantifying it and reducing it continuously and autonomously at scale. By aligning security and IT decisions directly with business priorities, we are providing organizations with measurable proactive risk reduction that brings customer value. Armed with this fresh new set of capabilities and early momentum already validating this model, we are now laser-focused on accelerating ETM adoption through our VMDR customer base, and positioning Qualys for larger upsell opportunities over time. Moving to our business update. With customers spending $50,000 or more with us growing 4% from a year ago to 215, let me now share a couple of recent wins which illustrate why organizations ready to centralize the response to cyber risk are turning to Qualys to help unify the security stack, quantify and remediate risk in their environment and fortify their security operations. First, an existing Global 50 customer was struggling under the weight of multiple unintegrated security tools, millions of vulnerabilities and limited visibility into the overall risk profile. Traditional prioritization methods were unable to adequately filter critical findings, leaving security and IT teams without the necessary business context to act decisively. Consequently, this customer selected Qualys and launched a strategic initiative to unify their security stack by transforming siloed risk signals spanning on-prem and multi-cloud environment into a cohesive, agentic AI-native risk management solution. This included expanding the ETM deployment to further operationalize the ROC with ingested third-party data from several sources, resulting in a mid-6-figure annual bookings upsell. By consolidating these data services into the Qualys platform, we are now delivering this customer a unified orchestration layer and full visibility of their attack surface, centralized risk assessment, quantification, prioritization and remediation workflows while unleashing the operational efficiency of the stack consolidation. This expansion of their ROC underscores the power of our platform and reinforces Qualys' ability to unify siloed risk signals, operate as an autonomous defense layer, strengthen customer outcomes aligned to the business risk tolerance, and advance our leadership in the industry. Leveraging our mROC partner ecosystem, we are also pulling new business into Qualys. During the planning stages of launching a new ETM POC with a global 200 company in Latin America, we secured a 7-figure annual bookings upsell, which included our TotalCloud CNAPP and Policy Audit solutions. This win demonstrates the leverage of our partner-led motion and our ability to convert early engagements into meaningful, multi-solution growth. Turning to our Federal business. We achieved a mid-6-figure expansion with one of the federal government's most visible shared security services utilized by several large government agencies nationwide. Faced with an overwhelming volume of security issues that limited resources to continuously assess risk across augmented tools and manual workflows, this customer chose Qualys for its cloud-native FedRAMP High Authorized platform to enable a centralized government program that quantitatively prioritizes risk with automated assessment, standard outputs and low operational overhead. Given the success of this deployment, we are now working towards a multi-agency ETM rollout representing a significant upsell opportunity as this shared services team prepares to operationalize its Risk Operation Center. These results alongside another 6-figure upsell with a separate large federal agency, reinforce our proven ability to align technical capabilities with operational outcomes that address modern security challenges and underscore the long-term growth opportunity in our Federal business. Beyond these wins, we are also gaining more leverage from our partner ecosystem. As we continue to endorse a partner-first sales motion, partner-led deal registration increased again in Q4, reflecting deeper alignment and execution across the channel. In addition, with well over a dozen certified mROC partners actively launching new services, momentum continues to build towards a global ROC alliance, fueling our capability, harnessing transformative solution sales and bringing new business to Qualys. Further contributing to our growth profile, in Q4, we continued beta testing QFlex to help customers accelerate and maximize adoption of the Qualys ETM platform. Given the strong customer response and early success of this model, we plan to continue to focus on proactively identifying opportunities to leverage QFlex to enable select customers and partners to accelerate their adoption of Qualys solutions in 2026. In summary, we are fundamentally changing how organizations manage pre-breach cyber risk by unifying CTEM with exploit confirmation, risk quantification and automated remediation powered by an agentic AI risk fabric. Our rapid pace of innovation and strategic investments are driving strong competitive differentiation, deeper ROC adoption, broader engagements across large federal agencies, growing partner-led execution and initial QFlex success. Looking ahead to 2026, we'll continue our disruptive innovation, further advance our go-to-market investments and execute our ROC vision with a balanced approach to long-term growth and profitability. With that, I will turn the call over to Joo Mi to further discuss our fourth quarter results and outlook for the first quarter and full year 2026.
