Zscaler to Acquire Symmetry Systems to Secure Enterprise AI Agents

Zscaler moves to map and secure ephemeral AI identities, a challenge legacy security models are not equipped to handle.

Zscaler Inc. announced its intent to acquire Symmetry Systems, a move designed to integrate identity mapping and data access controls into its zero-trust platform to govern the explosion of enterprise AI agents. The deal addresses a critical security gap created by autonomous AI agents that operate with ephemeral identities and inherited permissions, a scale traditional security policies cannot manage.

"As enterprises rapidly adopt AI, the old playbook for governing access built around users and directories cannot scale to millions of AI agents,” said Jay Chaudhry, Chairman and CEO of Zscaler. “With Symmetry Systems, we are adding the access graph that maps how every identity, application, and data source connects across the enterprise."

Symmetry Systems provides an access graph that ingests enterprise-wide logs from SaaS, cloud, data stores, and AI systems to reveal how human and non-human identities access data. This technology will be integrated into the Zscaler Zero Trust Exchange platform, providing the visibility needed to build and enforce security policies for AI agent communications. The transaction is expected to close in the coming days, though financial terms were not disclosed.

The acquisition strengthens Zscaler’s position in the high-growth AI security market, intensifying its competition with rivals like Palo Alto Networks and CrowdStrike. For Zscaler (NASDAQ: ZS), this move is critical to expanding its total addressable market by providing a foundational layer for AI security, potentially boosting revenue by offering customers a way to safely deploy large-scale AI initiatives without creating massive security blind spots.

The AI Identity Problem

Enterprises have traditionally governed access by mapping stable user groups to applications. AI agents, which can number in the millions, break this model. They operate independently across systems using temporary identities, creating a complex web of interactions that is nearly impossible to track with legacy tools. This creates significant blind spots regarding what data agents access and on whose behalf, posing a substantial security risk. Symmetry Systems’ technology directly targets this issue by providing a real-time map of these interactions.

Zero Trust for AI

The combined platform will allow security teams to set granular policies for agent-to-application and agent-to-agent communication. For example, if an AI agent accesses a sensitive customer record, the system will reveal the trigger, the identity used, and all systems it touched. If the behavior is deemed risky, Zscaler’s Zero Trust Exchange can dynamically enforce a policy response, such as blocking access. This capability moves beyond simple AI discovery and runtime guardrails to offer proactive governance.
