About NetScaler

NetScaler, a line of networking products now under the Cloud Software Group, originated in 1997, founded by Michel K Susai in San Jose, California, to address infrastructure challenges during the internet's rapid expansion. Another key figure in the company's early days was BV Jagadeesh, who served as a founding investor and CEO, bringing his experience from co-founding Exodus Communications, a pioneer in cloud hosting and data centers. This background in managing large-scale internet infrastructure was directly relevant to NetScaler's mission.

The company's initial product, the WebScaler 3000, launched in 2000. A significant shift occurred in 2001 when NetScaler repositioned itself as a security and optimization tool, releasing the NetScaler 6000 load balancer. This strategic move proved successful, and by 2005, an estimated 75% of internet users were interacting with systems using NetScaler technology, including major clients like Google and Amazon. This growth and market penetration led to its acquisition by Citrix Systems in June 2005 for approximately $300 million. Over the years, the product line expanded with more powerful hardware and the introduction of a multi-processor packet engine. In 2022, following the merger of Citrix and TIBCO Software, NetScaler was re-established as a distinct business unit within the newly formed Cloud Software Group.

NetScaler's core business revolves around its Application Delivery Controller (ADC) technology, which improves the speed, security, and quality of application delivery to end-users. The business model is centered on selling these networking solutions to enterprise customers. Its products perform crucial functions such as L4-L7 load balancing, traffic optimization, and web application acceleration. A key feature is its ability to monitor server health and intelligently distribute network traffic to ensure efficient resource use and high availability. The product portfolio includes the NetScaler ADC, NetScaler AppFirewall, and NetScaler Unified Gateway, among others. These offerings are available in various form factors to suit different client needs, including hardware-based appliances (MPX), virtualized versions for multi-tenancy (SDX), software-based virtual machines for smaller businesses (VPX), and containerized versions for cloud and microservices applications (CPX). This flexible deployment model, built on a single code base, ensures operational consistency whether on-premises or in the cloud. Revenue is generated through the sale of these hardware and software products and related services. The company's technology serves as the foundation for Citrix's virtual desktop infrastructure (VDI) and secure access solutions.
