Thank you, Vin, and welcome, everyone, to our Q1 earnings call. We hope that you and your families are healthy and safe, and that soon, America and the world will be open for business, again. It is now clear that after COVID-19, organizations and government agencies of all size are going to have to rethink the security and business continuity plans to include remote connectivity, accelerate their migration plans to the cloud and streamline and secure, if not reinvent, their supply and delivery chains. This will have a profound impact on our industry, as it has also become clear that most of the current security solutions were not designed for remote and highly interconnected working new work. In fact, we experienced these ourselves. Unlike most other companies, we suddenly have most of our workforce, working from home. Fortunately, because we had moved early with cloud-based enterprise application, and spent many years laying the architectural foundational work for a robust, scalable cloud platform, we were able to not only secure our remote workers, but also continuously monitor and patch validities under computers in a very short period of time. As a result, we could continue our engineering and business development initiative without much disruption. This was, in fact, the genesis for launching a cloud-based Remote Endpoint Protection free service in a matter of days. For our customers first, and now for the community at large by leveraging our powerful cloud platform and our strong base of engineering talent in Pune. As a result, today, we have close to 500 companies of which 50% – nearly 50% our new customers' prospects signed up for this free offering, which allows security teams to gain instant and continuous visibility of remote computers, easily see missing patches for clinical vulnerabilities and employ them from the cloud. This represents a deployment of approximately 2.1 million cloud agents on the endpoints, 1.4 million from existing customers and 700,000 from new prospects. The patches are delivered securely and directly from vendors' website and content delivery network, ensuring there is little to no impact on external VPN bandwidth. We are now planning to add malware detection capabilities in a couple of weeks and will extend the free service for another 60 days for those who adopt the malware detection capabilities, which, in fact, will be a prelude to bringing the power of our Cloud Platform, our Cloud Agents and passive technology to EDR, a new offering we plan to release this summer and as well to the Security and Event Management market later in the year. So what makes Qualys unique is the significant investment we have made as well as our determination over the years to build a highly scalable cloud-based platform that allows us to unify IT, security and compliance across the new hybrid environment. Early on, we recognize the importance of capturing all the necessary telemetry via our sensors, via the Internet and building the back end with the scale and computing capabilities needed to handle such a large volume of data. Today, we handle more than 9 petabytes of data, indexing now more than 6 trillion data points on our ElasticSearch clusters, moving 5 billion messages a day on our Kafka bus and pumping 1 million writes per second in our Cassandra log analysis engine. As a result, our cloud-based IT, security and compliance solution do not need to collect data from disparate sources, are easily deployable in environment with a dispersed and remote workforce, and this is what drove, in such difficult times, another good quarter in terms of revenue growth and profitability. This is underscored by the continued acceleration in our paid Cloud Agent subscriptions, with over 38 million now or 114% growth from the prior year quarter. We continue to see a good adoption of our free Global IT Asset Discovery and Inventory app with almost 9,000 new companies signed up and over 700 new companies actively using the service. We now have over 600 existing customers using the solution as well. We saw solid growth this quarter from our paid It Asset Discovery and Inventory and Cloud and Container solutions in fact, a leading financial services company added our IT Discovery and Inventory, paying modules this quarter in order to gain visibility of all the known and unknown assets, across multiple environments, identified the end-of-life of their installed software and synchronized with our ServiceNow CMDB. Also, a large existing bank, which had acquired a competitor, one of the competitor used this opportunity to not only adopt VMDR, but also to add many of our newer solutions, like FIM, Container Security, and Cloud Security Assessment, as they could consolidate many of their existing security solution in a single stack, where all the data could be correlated, far more cost effectively to provide a continuous and accurate view of the security and compliance posture, across their entire environment. Finally, Patch Management continued to see strong customer adoption in the mid-market. This quarter, as we are seeing strong and we also are seeing strong interest with our large customers as well. We're also pleased to announce that Qualys Container Security application is now available and the Qualys Vulnerability Management solution within a month in Microsoft Azure Security Center to all customers that are on Azure Security Center Standard Edition. This jointly developed solution automatically analyzes virtual machines and containers images in Azure, providing customers visibility into variabilities and configuration issues, which are reported to the Microsoft Azure Security Center, as recommendation, including the ability to create playbooks for one-click remediation with no software to deploy or update. Our Security Conference during RSA in Q1, where we unveiled Vulnerability Management, Detection and Response, VMDR, which is now in GA, was a huge success. VMDR takes vulnerability management to the next level by providing the power to continuously detect vulnerabilities and misconfiguration across the entire global IT hybrid environment and respond in real-time to remediate assets that are variable or already compromised from a single platform with built-in orchestration. We held a live virtual event on April 21, demonstrating how VMDR integrates Asset Discovery and Inventory with vulnerability assessment and patch detection in a single app. More than 3,000 people have registered to our VMDR live event, and over 600 organizations signed up for a VMDR trial after this event, 75% which were new customer prospects. For example, the Head of Security Research at Orange Cyber Defense in, one of our MSSP partners concluded that VMDR is going to shake up the vulnerability management space, given its focus on inventory, risk-based priorities and workflows as well as its strong use of ElasticSearch capabilities. In fact, Armor saw the opportunity to integrate VMDR with the Armor Anywhere managed security offering and Armor Anywhere customers will now have access to the newly announced Qualys VMDR application, as part of a holistic solution to meet their Vulnerability Threat Management, VTM requirements and provide visibility across the entire hybrid environment. Qualys Cloud Agents are embedded and fully integrated with the Armor platform to deliver asset discovery and inventory, vulnerability assessment, including configuration control, threat prioritization and patch detection to Armor customers. In addition, this quarter, Qualys was recognized as a Gartner Peer Insights Customers Choice for Vulnerability Assessment. VMDR is effortless to deploy on a global scale and priced as a fully branded solution, drastically saving deployment, administration and software subscription costs with real-time, light-weight Cloud Agents and Virtual Scanners that are self-updating and easy to deploy. Our game-changing VMDR application was also highlighted during the quarter in a report by Ovum, the market-leading data research and consulting firm and you can review it at www.qualys.com/phones/whitepapers/ovum. In Q1 nearly 150 customers, existing customers, adopted VMDR, which included approximately 60 new customers and seven of our top existing customers, up for renewal in Q1, renewed into VMDR subscription. In fact, 3.9 million out of our 38 million paid Cloud Agents subscription came from VMDR, of which 3 million were new agent subscription, laying the foundation for ubiquity of our agent, which is the technology platform for seven security and compliance and IT solutions, namely Vulnerability Management, Policy Compliance, File Integrity Monitoring, Indication of Compromise, Patch Management, Asset Inventory and the upcoming Certificate Management and with more to come. In addition, earlier this month, we also announced general availability of the Qualys Cloud Agent on the Google Cloud platform, GCP. GCP Customers can now easily activate multiple Qualys applications, including our game-changing VMDR application to build a streamlined workflow within GCP. Also, at our user conference, this past quarter, we participated in a number of impromptu videos, which you can access at www.qualys.com/qsc/2020san-francisco. These videos underscore the fact that the security industry is on the verge of a major transformation as many of the current solutions offered by a plethora of vendors are becoming inadequate, as the architecture of our corporate network is drastically and rapidly changing. We saw this coming quite a while ago. And as mentioned earlier, we took the time to properly build our offering with this need in mind. These efforts being the foundation for our leadership position in our market, and we continue to innovate first, with VMDR, which went live in April and with the next-generation of SIEM and EDR, which we expect to deliver for beta at the end of the year, and EDR early this summer. In addition, we will deliver significant extension similar to our VMDR to our current offering, providing detection and response capabilities across cloud, mobile, SaaS, OT and IoT environments by adding response capabilities to our Cloud Agent and additional detection capabilities to our network analysis efforts or passive scanning efforts. Looking forward, we believe the world after COVID-19 is going to be different. Companies are going to be more focused on reducing costs, while increasing business flexibility, which is going to be a significant driver to a faster adoption of cloud-based solutions. In the current uncertain environment, we're fortunate to have a stable foundation of recurring revenues and a highly profitable model, which we believe can withstand short-term disruptions. Finally, because of the very nature of our business model, which is 100% recurring, and the fact that our solutions have become mission critical to have a greater visibility than many other security companies in our industry, even in such difficult times, not to mention our stellar profitability. With that, I will turn the call over to Melissa to discuss our financial results and guidance for the second and full-year fiscal 2020. Melissa?
