The internet is now the primary network for business applications, user activity, and data exchange. Employees access SaaS platforms, cloud services, and web applications directly from anywhere, often outside traditional network controls. A modern Secure Web Gateway must do more than block threats—it must provide real-time visibility, enforce data protection policies, and control how users interact with the internet across all locations.
Legacy secure web gateways and firewalls were designed for centralized networks, where traffic passed through a data center perimeter. That model no longer exists. Users connect directly to the internet, applications are distributed across cloud platforms, and encrypted traffic dominates.
This creates significant challenges:
Organizations lack visibility into SaaS, AI and web usage, making it difficult to identify risk. Sensitive data can leave the organization without inspection or control. Security policies are inconsistent across office, remote, and mobile users. At the same time, threats have evolved to exploit encrypted channels and cloud services.
Zscaler Internet Access (ZIA) is the world’s leading Secure Web Gateway (SWG), delivering cloud–native, AI–powered cyberthreat protection to the Internet and SaaS apps. Zscaler’s full proxy architecture enables TLS/SSL inspection at scale, with connections brokered between users and applications based on identity, context, and business policies. ZIA is part of the Zero Trust Exchange (ZTE), and all Internet–bound traffic is be sent through the ZTE.
Zscaler Internet Access (ZIA) Sits inline between your company and the Internet, protecting your enterprise from cyberthreats, stopping intellectual property leaks, and ensuring compliance with corporate content and access policies.
ZIA monitors your network and user activity, secures roaming users and mobile devices, and manages all of this globally from a single management console. There is no hardware to buy, no appliances to manage and policy changes can be effected globally across your organization from a single console in minutes.
Zscaler Internet Access (ZIA) can protect your employees from malware (including Ransomware), viruses and other Internet threats, blocking attacks in real time. Zscaler security services scan and filter every byte of your network traffic, including SSL-encrypted sessions , as it passes to and from the Internet.
Zscaler Internet Security, when combined with ZIA, enables confident, secure AI adoption with a solution that offers AI asset management, secure access to AI, and security for enterprise AI apps and infrastructure, without inhibiting innovation.
Zscaler Internet Access (ZIA) provides a Secure Service Edge (SSE), which when combined with an SD–WAN product such as Aruba EdgeConnect can provide a complete SASE architecture. It allows secure local breakout for your branch network. SD–WAN makes local breakouts easy. Zscaler makes them secure. Learn more: Network Transformation
One advantage of a cloud–delivered security gateway is that it can be delivered very quickly. See Rapid Internet Protection for a discussion on how protection can be enabled very rapidly. One major airline in the United States, responding to an urgent cyber–event deployed Zscaler to the majority of its users (over 60,000 users) over one weekend, and that included planning time!
The Zero Trust Exchange (ZTE) is the core component of the Zscaler Secure Web Gateway. All traffic, including encrypted traffic can be routed through the ZTE for inspection and control

Zscaler can also help protect IoT (Internet of Things) and OT (Operational Technology) environments, and help to enable Industry 4.0 in industrial environments. Zscaler can allow for secure data exchange in IoT environments such as Smart City and power generation, and help protect legacy OT environments by providing a Zero Trust Exchange between OT and IT systems.
A modern Secure Web Gateway is a foundational control for managing how users interact with the internet, SaaS applications, and cloud services. As organizations move away from traditional network perimeters, solutions like Zscaler Internet Access provide the visibility, control, and protection required to secure web traffic in real time. The following FAQs address common questions around how a cloud-native SWG works and how it helps organizations reduce risk while enabling secure access from any location.
A Secure Web Gateway is a security control that sits between users and the internet, inspecting and governing web traffic in real time. It is important because most business activity now happens over the internet, including SaaS applications and cloud services. Without a modern SWG, organizations lack visibility into user activity, cannot effectively prevent data loss, and remain exposed to web-based threats.
Zscaler Internet Access is delivered as a cloud-native service rather than an on-premise appliance. Instead of routing traffic through a data center, it inspects traffic inline through a globally distributed platform. This allows organizations to enforce consistent security policies for all users, regardless of location, while eliminating the performance and scalability limitations of traditional gateways.
Zscaler performs full SSL/TLS inspection at scale, allowing organizations to identify threats and enforce policies within encrypted traffic. Since the majority of internet traffic is now encrypted, this capability is essential for detecting malware, preventing data leakage, and maintaining visibility into user activity.
Zscaler includes integrated Data Loss Prevention capabilities that inspect outbound traffic in real time. It can detect sensitive information such as personal data, financial records, or intellectual property and apply policies to block, allow, or log the activity. This ensures that data is protected as users interact with web and SaaS applications.
Zscaler provides detailed visibility into all web and SaaS applications being accessed by users. It can identify unsanctioned or risky applications and allow organizations to apply policies that restrict or control their use. This helps reduce risk associated with shadow IT while enabling safe adoption of cloud services.
Zscaler is designed to improve user experience by routing traffic directly to the nearest point of presence rather than backhauling it through a central data center. This reduces latency and improves application performance, particularly for cloud and SaaS applications, while still enforcing full security inspection.
Zscaler uses a combination of real-time inspection, threat intelligence, and advanced detection techniques to identify and block malicious content before it reaches the user. By inspecting traffic inline and enforcing policy before connections are established, it reduces the attack surface and prevents threats from entering the environment.
Because Zscaler operates in the cloud, it applies the same security policies to users regardless of where they are located. Whether users are in an office, at home, or traveling, their internet traffic is routed through the Zscaler platform, ensuring consistent protection without relying on VPNs or on-premise infrastructure.
Zscaler provides centralized logging and reporting across all internet activity, allowing organizations to demonstrate how policies are enforced and how data is protected. Security and compliance teams can generate reports that show user activity, application usage, and policy enforcement, making it easier to meet regulatory requirements and internal governance standards.
