Globally recognized, Zscaler, Inc. functions as a leading provider of cloud-based security solutions. Its core offerings include Zscaler Internet Access (ZIA), which ensures secure connectivity for a diverse range of entities – including users, servers, operational technology (OT), and IoT devices – when accessing external resources like software-as-a-service (SaaS) applications and general internet destinations. Complementing this, the Zscaler Private Access (ZPA) solution facilitates secure entry to internal applications residing in private or public clouds and traditional data centers. Zscaler also delivers Zscaler Digital Experience (ZDX), a tool that assesses the complete user journey across various business applications. ZDX then generates a clear, digestible digital experience score for individual users, specific applications, and different locations within an organization. Furthermore, the company's portfolio extends to advanced workload segmentation solutions. This category includes Zscaler Cloud Security Posture Management (CSPM), designed to identify and correct application misconfigurations across SaaS, IaaS, and PaaS environments, thereby minimizing risk and upholding compliance standards. Another key offering is Zscaler Cloud Workload Segmentation, specifically engineered to fortify application-to-application communication within public clouds and data centers. Its objective is to thwart lateral threat propagation, safeguard applications from compromise, and ultimately mitigate the potential for data breaches. The underlying platform is built upon integral components such as the Zscaler Central Authority, Zscaler Enforcement Nodes, and Zscaler Log Servers. Serving a diverse global clientele, Zscaler caters to numerous sectors including aviation and transportation, conglomerates, consumer goods and retail, financial services, healthcare, manufacturing, media and communications, public sector and education, as well as technology and telecommunications.
