Thank you, Blair, and welcome to our first quarter earnings call. Qualys delivered another quarter of healthy revenue growth, strong profitability and cash flow generation, reflecting our ongoing commitment to rapid innovation and customer success. Given the accelerated growth in scope and complexity of cyber threats alongside an intensifying regulatory environment, boards and C-level executives are increasingly focused on the business outcome of cybersecurity. This requirement makes seamlessly integrated security solutions and necessity for customers to effectively measure, communicate and fortify the security posture. We believe the Qualys Enterprise TruRisk Platform designed to reduce friction, risk and cost provides organizations with a foundational risk management platform for the future and serves as a structural competitive advantage for both our customers and for Qualys. As a result, our VMDR solution with TruRisk is not only fueling new logo lands but also increases platform adoption, especially in the areas of the CyberSecurity Asset Management with External Attack Surface Management, Patch Management and Cloud Security. In Q1, health care, technology, retail and financial services verticals all demonstrated strong VMDR demand with large deal sizes. Further underscoring the power of our platform, I will take a moment to share a couple of examples of how our customers and partners continue to expand their use of Qualys' capabilities to consolidate their security stack. On the customer front, a marquee high 6-figure bookings enterprise customer win in Q1 was with a leading business services company in the Forbes 1000. The customer expanded its VMDR with TruRisk and Patch Management deployments with -- while adopting CyberSecurity Asset Management with EASM as part of an initiative to detect end-of-life and end-of-service software, monitor subdomains of its infrastructure and transform its IT security architecture, while replacing point solutions from 3 vendors with a single platform. The ability for this customer to significantly enhance its security program with comprehensive internal and external asset criticality, holistic risk scoring, ticketing and automated patching across its on-prem cloud and container environments through a natively integrated platform and unified dashboard were all key differentiators compared to alternative next-gen and legacy technologies. The next win demonstrates how Qualys helped an existing Forbes 100 manufacturing company standardized on Qualys Enterprise TruRisk Platform. and consolidate risk factors from different Qualys modules into a single risk score with business context. This existing VMDR and total cloud customer was struggling with connecting disparate asset management tools and business processes across several subsidiaries and environments and needed to gain better visibility into its attack surface to uniformly contextualized, communicate and manage risk. Recognizing the increased value they would gain by further consolidating on Qualys, this customer replaced its existing asset management tool and adopted our CyberSecurity Asset Management with EASM solution in a 6-figure bookings upsell. This customer is now leveraging multiple aspects of Qualys Enterprise TruRisk Platform, spanning on-prem cloud and multi-cloud assets to quantify and prioritize risk reduction initiatives, increase organizational resilience and give its CISO a peace of mind. Investing in our partner program continues to be a key pillar of our go-to-market agenda as it bolsters our capacities, harness transformative solution sales and bring new business to Qualys. Through these investments, we continue to advance our evolving partner ecosystem with 2 leading managed service providers in America, one that recently expanded its offering beyond VMDR to include our Patch Management capability and the other standardized on Qualys as its preferred partner for VMDR CyberSecurity Asset Management with EASM and Patch Management, spanning both its federal and commercial verticals. The latter of these 2 wins is a testament to the investment we are making to expand our federal business, and we're looking forward to hosting our first public sector Cyber Risk Conference later this month. And with nearly 50 partners already on our recently announced new MSSP partner portal to simplify their operations, launch and manage Qualys' capabilities and significantly reduce remediation times for their customers, we are increasingly well positioned to expand our reach to customers of all sizes. Additionally, we strengthened our alliance with a leading system integrator, which is now actively bringing our TotalCloud CNAPP solution to its customers. We believe the broad expansion of our partner program over the past several quarters continues to reflect our strengthening brand awareness, strategic position and value position in the market. With tightly integrated solutions delivered through a natively integrated platform to solve modern security challenges, more and more Qualys customers are beginning to understand how cybersecurity transformation drives better security outcomes, saves times and costs less. As a result, customers spending $500,000 or more with us in Q1 grew 19% from a year ago to 192. Since our inception driving innovation is at the core of Qualys' mission. We are excited with our upcoming enterprise TruRisk Management application, which marks the next phase of expansion of our platform, building on top of the success we have seen with VMDR -- with TruRisk. The ETM capability will enable VMDR customers to upgrade to a more holistic cyber risk management platform that goes beyond vulnerability management. the enterprise tourist management solution holistically aggregates and normalizes trillions of first- and third-party data signals, correlates risk factors with assets, threats and business context, detects visualizes, quantifies and prioritize risk and makes remediation frictionless with immediate -- and immediate with simple click of a button. With these newest capabilities all natively integrated off single unified dashboard Qualys is once again well armed with powerful new platform capabilities that broadly measure, communicate and remediate risk across our attack surface including IT, OT, applications, cloud and multi-cloud assets. Moreover, our comprehensive AI-powered insights are now converting detected risk into optimized remediation actions across our platform solutions with our out-of-the-box instant and actionable insights mapped to our organization's own data to preemptively reduce risk in their environment. The feedback from many of the CISOs I met at our recent QSC EMEA event in London has been very positive with respect to the deployment agenda, the excitement about the rapid pace of new capabilities that we are delivering and their ability to monitor and measure risk reduction ROI for the cybersecurity spend. Further advancing our TruRisk capabilities, I'm pleased to announce we recently brought MITRE ATT&CK Matrix Prioritization into the Qualys Enterprise TruRisk Platform. By combining over 25 sources of threat intelligence with the MITRE ATT&CK framework, we are now further enabling organizations with a holistic attacker centric view to predict and identify critical risks to their business based on the attack tactics and techniques. While this advancement -- with this advancement, we believe Qualys stands out as the only enterprise scale solution to combine contextualized risk quantification and the MITRE ATT&CK framework to help organizations proactively prioritize, manage and reduce cyber risk with enhanced detection, integrated risk quantification and automated response for a threat-informed defense in a single platform. Continuing the pace of disruptive innovation, we are now organically unifying cloud infrastructure entitlement management, CIEM into our TotalCloud CNAPP solution. With this new capability, customers can manage cloud entities, entitlements and enforce the principle of least privilege access to cloud infrastructure and resources. Combined with additional newly introduced capabilities such as container runtime security and Kubernetes posture management, we have created what we believe is one of the most comprehensive cloud-native security solutions in the market with a unified actionable dashboard for immediate threat prioritization and remediation for build through runtime with built-in threat detection capabilities. Finally, we -- as we continue to extend our technology leadership across the entire platform, I'm pleased to announce our CyberSecurity Risk Management 3.0 solution with highly differentiated new capabilities and external attack surface success management and third-party integrations for comprehensive asset inventory. With these innovations, security teams can now leverage our patent pending technology to reduce accuracy and detection gaps with immediate lightweight vulnerability scanning, seamlessly attribute previously unmanaged external assets to the organization with confidence and evaluate asset-based business risk per subsidiary or acquired entity. Combining this unique approach to EASM with integrated TruRisk scoring capabilities and actionable dashboards to proactively manage tech debt further strengthens our position in the market while enabling customers to derisk the entire attack surface. In summary, company's uniformly recognized security transformation is fundamental in combat in today's heightened threat and regulatory environment. As a result, customers are increasingly looking to reduce the risk exposure through the adoption of natively integrated risk management platform instead of deploying a collection of disparate point solutions stitched together through the invoice. We believe that with our organically integrated cloud-native platform built to holistically measure, communicate and ultimately eliminate cyber risk, Qualys is laying a foundation for future growth and is well positioned to drive long-term shareholder value with a balanced approach to growth and profitability. With that, I will turn the call over to Joo Mi to further discuss our first quarter results and outlook for the second quarter and full year 2024.
