Thank you, Tom, and thank you all for joining us today. Our first quarter results were in line with the estimates we shared on April 3. While revenue was impacted by the economy and slowing purchasing decisions, the team moved quickly to respond to these changes, and we maintain our profitability at historical levels better positioning us to achieve our full year targets for non-GAAP EPS. This was due in large part to the focus on driving a more resilient and durable business model. As previously communicated, we believe the first quarter will represent a floor for our results this year, and we expect sequential improvements as we move through the balance of 2023. While large enterprises and especially Tier 1 service providers are more carefully considering investments due to the economy, security solutions remain a priority and are increasingly not a discretionary consideration. Companies around the world, even those with robust security processes and controls are experiencing an ever-growing threat of cyber attack. During the first quarter, we further augmented our already robust security infrastructure to enable us to better support our customers against these threats. Cyber attacks are simply a business reality for even the most prepared organization and that deploying solutions to mitigate this risk and the associated disruptions they cause is a priority even during challenging times. Like others, we are seeing longer sales cycles, particularly among larger North American customers due to concerns about the economy. We do not believe we have lost any meaningful forecasted deals to competitors, but they are taking longer to close, impacting our normal revenue cadence. I Indeed, North America declined 9% in the first quarter compared to last year, and revenue in the rest of the world was down 7% year-over-year. Effectively, all of this revenue decline was due to Tier 1 customers who post plan buying in the quarter with expectations of resumption in the second half of the year. Our diversification, both in terms of geography and customers helped us mitigate the macro environment as we believe we are navigating the economy better than most, but we were not immune from the conditions. Proactively, we have taken steps to align our cost structure. We deployed select austerity measures to reduce operating expenses by 10.3% year-over-year in Q1 in light of these macro headwinds. I want to note that we were mindful of our long-term goals, particularly related to growth as we reviewed our near-term spending. Over the long term, I don't believe this effort will materially impact our business trajectory, our ability to achieve multiyear targets as market conditions normalize. In reality, our ability to maintain solid profitability and cash generation even during a quarter with significant revenue challenges speaks to the durability of our business model and execution. As a result, we maintained our gross margins in excess of 80% and significantly expanded our adjusted EBITDA margin to 26.8%, and versus 21.6% in last year's first quarter. This is in line with our business model goals of achieving 26% to 28% EBITDA and 80% gross margin. As we have previously communicated, our ability to proactively manage investments and certain expenses enables us to maintain robust profitability even when revenues are under external pressure. We have continued to methodically plan these actions, including supply chain, sales and marketing investment and selected strategic investments in R&D. In an effort to improve the security and resiliency of our hybrid cloud offering, we recently announced a strategic partnership with Fastly [ph] an industry leader in next-generation web application firewall or WAC. By combining our leading ADC solution with their next-generation RAP, this first-to-market integrated solution can provide our large enterprise customers, a single solution to enhance web defenses across software and hardware appliances within their hybrid cloud environment. We believe this partnership strengthens our portfolio and unlocks further diversification of our revenue stream. Additionally, our collaboration should broaden our go-to-market strategy for this type of solution as we leverage the reach and capability of both AN and Fastly teams. Additionally, in Q1 and in line with these diversification efforts, a large partner in Japan introduced A10's cloud access controller into their security operations center service package. And Networks cloud access proxy is a complete enterprise solution designed specifically to help organizations optimize the performance and security of their SaaS applications, enhanced user experience and provide comprehensive visibility into branch offices and the cloud. With a partner enabling this as a service, it is further proof that we continue to invest in comprehensive security solutions delivered through multiple form factors for our customers. In the first quarter, our revenue was negatively impacted by the combination of macroeconomic headwinds and internal company priorities to strengthen our security posture. But our business model and focus on execution enabled us to preserve our profitability. We are confident that we will show improvement as we move through the year, and we continue to expect full year EPS expansion. We also continue to maintain a disciplined, flexible and opportunistic capital allocation strategy. Today, our Board approved a quarterly dividend of $0.06 per share. With that, I'd like to turn the call over to Brian for a detailed review of the quarter. Brian?
