Comprehensive online documentation, deployment guides and knowledge base articles covering setup, configuration and operations are provided. Online training and certification courses are available through Zscaler training platforms for administrators and engineers. Initial onboarding is typically supported remotely, rather than onsite by default. Ongoing support is provided through technical support channels, best practice guidance and regular service updates, enabling customers to adopt and operate the service effectively.

• End-of-contract data extraction: We explore this at a contract closure.
• End-of-contract process: Any existing hosted services are transitioned to the customer.; All existing support contracts are terminated.
• Documentation accessibility standard: None or don’t know
• How the documentation is accessible: Zscaler documentation is delivered primarily through web based HTML documentation and knowledge base articles. Content can be accessed using standard browsers and supports common accessibility features such as zoom, text resizing and screen magnification. Documentation follows a structured layout with headings, links and searchable content to aid navigation. While no formal accessibility certification is published, the documentation is usable with standard assistive technologies supported by modern browsers. Some diagrams and embedded content may have limited alternative text, which can restrict accessibility for screen reader users.

Using the service

• Web browser interface: Yes
• Supported browsers:
  • Microsoft Edge
  • Firefox
  • Chrome
  • Safari
  • Opera
  • Other
• Application to install: Yes
• Compatible operating systems:
  • Android
  • IOS
  • Linux or Unix
  • MacOS
  • Windows
  • ChromeOS
• Designed for use on mobile devices: Yes
• Differences between the mobile and desktop service: Zscaler Internet Access supports mobile devices through the Zscaler Client Connector on iOS and Android. Core security controls such as web filtering, threat protection and policy enforcement are consistent with desktop platforms. Some advanced features, diagnostics and traffic handling options are more limited on mobile due to operating system restrictions. Mobile support is optimised for user transparency and battery efficiency, while desktop platforms provide broader visibility, configuration flexibility and troubleshooting capabilities for security and IT teams.
• Service interface: Yes
• User support accessibility: None or don’t know
• Description of service interface: Zscaler Internet Access is managed through a cloud based web admin portal used to configure security policies, user access, data protection and threat controls. The interface provides dashboards, logs and reporting for visibility and investigation. End users interact through the Zscaler Client Connector, which runs in the background and provides connection status and basic controls, requiring minimal user interaction while enforcing security transparently.
• Accessibility standards: None or don’t know
• Description of accessibility: Zscaler Internet Access interfaces follow modern web design and operating system accessibility features but are not formally certified against WCAG 2.2 or EN 301 549. Users can navigate the admin portal using standard browsers, adjust zoom and contrast and use native OS accessibility features such as screen magnification. The Zscaler Client Connector is designed to run with minimal user interaction. Some advanced configuration workflows and dashboards may be challenging for users relying on screen readers or full keyboard-only navigation.
• Accessibility testing: No formal or published interface testing has been conducted with users of assistive technology. Zscaler has not released documentation confirming usability testing with screen readers, keyboard-only navigation or other assistive technologies, so accessibility support is based on standard browser and operating system capabilities rather than validated testing outcomes.
• API: Yes
• What users can and can't do using the API: Zscaler Internet Access provides REST APIs that allow administrators to configure and manage the service programmatically. Users can create and update security policies, URL categories, firewall rules, DLP settings and user or group mappings. Configuration changes and bulk updates can be made through the API to support automation and integration with external systems. Reporting and log data can also be retrieved. Some initial tenant setup, advanced configuration options and certain feature enablement steps still require use of the admin portal. API access is controlled by roles and platform limits.
• API documentation: Yes
• API documentation formats: HTML
• API sandbox or test environment: Yes
• Customisation available: Yes
• Description of customisation: Users can customise Zscaler Internet Access through configuration rather than code changes. Customisable elements include web access policies, URL filtering, firewall rules, SSL inspection, DLP policies, CASB controls, threat protection settings and reporting. Customisation is performed through the web based admin portal or via APIs for automation and integration. Access is controlled using role based permissions, so only authorised administrators can make changes. End users cannot modify security controls, ensuring consistent enforcement and reducing operational and security risk across the organisation.

Scaling

• Independence of resources: Zscaler security as a service is delivered by a next-generation security architecture built from the ground up for performance and scalability. It is distributed across more than 100 data centers on 6 continents, which means that users are always a short hop to their applications, and we peer with hundreds of partners in major internet exchanges around the world for performance and reliability.

Data importing and exporting

• Data export approach: Users export data through the Zscaler web-based admin portal and APIs. Administrators can download reports, logs and configuration data in standard formats such as CSV or JSON, or retrieve data programmatically via REST APIs. Operational and security logs are commonly exported by forwarding them to external SIEM or logging platforms during the contract term. Data export must be completed before tenant decommissioning, as access is removed once the service is terminated.
• Data export formats: CSV
• Data import formats: CSV

Data-in-transit protection

• Data protection between buyer and supplier networks: TLS (version 1.2 or above)
• Data protection within supplier network: TLS (version 1.2 or above)

• Guaranteed availability: Standard SLA's are as follows:; < 30 minutes P1; < 90 minutes P2; < 4 Hours P3; ; Service credits are assigned on a company by company basis.
• Approach to resilience: Zscaler security as a service is delivered by a next-generation security architecture built from the ground up for performance and scalability. It is distributed across more than 150 data centers on 6 continents, which means that users are always a short hop to their applications and we peer with hundreds of partners in major internet exchanges around the world for performance and reliability.
• Outage reporting: Zscaler reports service outages and incidents through multiple channels to ensure timely visibility. A public service status dashboard provides real time and historical information on platform availability and incidents. Customers can subscribe to email alerts for service disruptions, maintenance notifications and incident updates. Service health and operational status can also be accessed through APIs and administrative notifications within the Zscaler portal. This multi-channel approach ensures customers receive clear, timely information and can respond effectively to any service impact.

  • Other
• Other user authentication: Device posture checks and certificate based trust can be enforced as part of the authentication and access decision.
• Access restrictions in management interfaces and support channels: Access to Zscaler management interfaces and support channels is tightly restricted using role based access controls and strong authentication. Administrative access to the Zscaler portal requires authenticated identities, typically federated with an enterprise identity provider, and supports multi factor authentication. Permissions are granted on a least privilege basis, limiting what each administrator can view or change. Support access is controlled through authenticated support accounts, case based access and audit logging. All administrative and support actions are logged and monitored to detect misuse and support compliance and forensic review.
• Access restriction testing frequency: Less than once a year
• Management access authentication:
  • Multi-Factor Authentication (MFA)
