Zscaler's inline zero trust architecture applies effective AI guardrails to ensure safe use of public AI, protect private AI from malicious attacks, and stop AI-powered threats. With the power of zero trust and AI, we help organizations strengthen and automate IT and security, reduce costs, and minimize complexity. 

• AI Visibility: See all AI apps/assistants, prompts, and responses
• Granular AI Usage Policy Control- Block unsanctioned AI apps, and control access and usage based on who is using AI and how.
• AI Isolation: Allow usage of AI tools while preventing risky data sharing
• AI Guardrails: Block prompt injections, PII exposure, data poisoning, malicious outputs, and more
• AI Data Protection: Block sharing and exfiltration of data to prevent data breaches.
• AI Audit Trail: Keep full logs of users, prompts, responses, and apps.

Zscaler AI Guard is a security solution within the Zscaler Zero Trust Exchange designed to help organizations safely adopt and manage Generative AI (GenAI) applications like ChatGPT, Google Gemini, and Midjourney.

It acts as a set of "smart guardrails" that allow employees to use AI tools for productivity while ensuring that sensitive company data and citizen privacy are protected.

Key Capabilities

• Discovery and Visibility: Automatically identifies all GenAI tools being used across the organization (including "Shadow AI") and provides a risk score for each application.
• Data Loss Prevention (DLP): Monitors and blocks the uploading or pasting of sensitive information—such as PII (Personally Identifiable Information), health data, or intellectual property—into AI prompts.
• Prompt and Output Filtering: Inspects AI interactions in real-time to block risky prompts or prevent the AI from returning malicious or inappropriate content.
• Access Control: Allows administrators to define granular policies for who can use specific AI tools based on their role, department, or device posture.
• Browser Isolation: Can force AI sessions to run in a secure, isolated container, preventing risky actions like file downloads or clipboard sharing.

Why It Matters

Without a tool like AI Guard, organizations often face a "binary choice": either block GenAI entirely (stifling innovation) or allow it completely (risking data leaks). AI Guard provides a middle ground, enabling secure, policy-governed use of AI.

WWT & Zscaler AI relies on an advanced AI infrastructure, with models processing more than 5 trillion daily signals from the Zero Trust Exchange and 150+ third-party integrations. This AI infrastructure enables capabilities like security copilots, data classification, zero-day detection, malware identification, and digital experience enhancements, ensuring superior security and IT outcomes. AI is woven into our zero trust architecture, allowing it to quickly update zero trust security posture with AI-enhanced policies to block AI-enabled attacks.
