Secure internet access, private application access, data protection and digital experience monitoring through Zscaler’s Zero Trust Exchange.
Zscaler’s Zero Trust Exchange is a cloud-native platform that securely connects users, devices, and workloads to applications — never the network. Unlike traditional VPNs or firewalls, it applies identity and context-based policies to ensure only authorized access, minimizing the attack surface. The platform delivers Zero Trust Network Access (ZTNA), Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Firewall (FW), and Data Protection in one integrated service. With inline inspection of encrypted traffic and real–time threat prevention, the Zero Trust Exchange reduces risk, prevents lateral movement, and improves user experience. It enables enterprises to adopt cloud and hybrid work securely, at scale, and with confidence.
Zscaler lets organisations consolidate multiple security functions into a single cloud-delivered platform, reducing appliance sprawl, simplifying policy enforcement and giving users secure access from anywhere. This is especially relevant where customers are trying to reduce VPN reliance, modernise internet security, improve SaaS controls and gain better visibility into user experience. Simplifying the security environment also enables consolidated reporting for better security awareness and for regulatory reporting.
Zscaler’s cloud–native Zero Trust Exchange secures users, devices, and apps anywhere—without traditional perimeters. With integrated SWG, CASB, ZTNA, firewall, and DLP, Zscaler simplifies IT, blocks threats in real time, and ensures safe, seamless cloud adoption for enterprises worldwide.

ZPA provides secure remote access. The patented Zscaler Private Access solution works by abstracting the private, internal application from the network on which it resides, providing access from authorized users to specific applications via encrypted, per–session microtunnels that are created upon demand.
The end user is never directly connected to the application, nor is the user connected to the network on which the application resides. ZPA instead delivers functionality similar to a forward and a reverse proxy acting together. This ensures that networks and applications cannot be infected or exploited by open network tunnels.
Securing users is only part of the challenge. Organisations also need to ensure that users have a consistent, high-quality experience when accessing SaaS applications, cloud services and private applications from anywhere. Zscaler Digital Experience (ZDX) provides end-to-end visibility into the digital user experience, helping IT teams quickly identify whether performance issues originate from the endpoint, local network, ISP, Zscaler cloud or the application itself.
By combining application performance monitoring with detailed network and endpoint telemetry, ZDX significantly reduces troubleshooting time and improves operational visibility across distributed workforces. Rather than relying on multiple monitoring tools, organisations gain a unified view of the complete user journey, enabling faster problem resolution and a better overall user experience.
Zscaler Digital Experience
Zscaler’s Data Protection suite safeguards sensitive information across cloud, web, email, and private applications with a unified, cloud-native approach. Built on the Zero Trust Exchange, it combines data loss prevention (DLP), cloud access security broker (CASB), inline encryption, and advanced threat protection to prevent leaks and misuse. The platform inspects all traffic—encrypted and unencrypted—without slowing performance, giving enterprises full visibility and control over sensitive data. With integrated policies and real-time threat intelligence, Zscaler enables compliance, reduces risk, and protects intellectual property, ensuring data remains secure wherever users, workloads, and applications are located.
Zscaler Data Loss Prevention (DLP) helps organisations protect sensitive data across web, SaaS applications, email, endpoints, private applications, cloud workloads, BYOD devices, and AI interactions using a single, unified policy framework. Unlike traditional DLP solutions that rely on multiple products and fragmented controls, Zscaler delivers consistent protection from the world's largest inline security cloud, reducing operational complexity while providing visibility and control over how data is accessed, shared, and transferred.
