Zscaler Is Buying the Map for AI Agent Data Access

Every time an AI agent inside an enterprise spawns, it inherits a web of permissions it was never explicitly granted. It operates across SaaS apps, cloud services, and data stores for milliseconds, then dies, leaving no audit trail a human administrator can read. This is not a hypothetical problem. It is the operating reality of any company deploying AI agents at scale, and no traditional identity directory was built to track it.

Zscaler announced on May 21 that it would acquire Symmetry Systems to fix exactly that, according to GlobeNewswire and HPCwire. It was not a product launch. Zscaler spent the announcement describing a data access graph: a technology that maps every path an AI agent can take through enterprise data. The press release presented this as a coherent platform category. What it actually represents is an expensive bet on a category that has not yet been proven in production at scale.

The stakes are not abstract. A 2025 Lightspeed Venture Partners CISO survey found that 61% of security leaders reported their organizations had deployed or were actively evaluating AI agents, but fewer than a third had a mature framework for tracking what those agents could access or what data they touched. That gap — between rapid AI agent deployment and lagging visibility into their data access patterns — is the operational failure mode Symmetry was built to address. Whether it actually does, and at what scale, is unproven from public records.

Symmetry Systems is not a large company. It raised roughly $35.7 million across its lifetime, according to its own fundraising announcements, making it a small UT Austin spinout with a research pedigree: Symmetry CEO Mohit Tiwari was a cybersecurity professor at the university before co-founding the company, and the startup traces its technical roots to DARPA-funded information-flow-control research dating back to 2010, according to Symmetry's about page. The company operates two platforms, DataGuard and AIGuard, both built on what Symmetry calls a Data Access Graph architecture, per the Symmetry blog. Neither the Zscaler nor Symmetry press release names a single enterprise customer with a live deployment. No deal value was disclosed. The transaction is expected to close in the coming days.

The framing of this deal as a routine acquisition will not survive contact with the competitive landscape. Veza, a peer company backed by Accel and Greenspring Associates, has been marketing an Access Graph product for human and non-human identity security since at least 2022. CrowdStrike, Palo Alto Networks, and Microsoft have each disclosed AI agent security features within their broader platforms, but none have announced a dedicated access graph product for AI agent permissions. The race to own the control plane for AI agent data access has no clear winner, and the category definition is still open.

The question the press release does not answer, and which Zscaler will need to answer for customers and investors, is whether the access graph is a product integrated into the Zscaler Zero Trust Exchange or a separate developer-facing tool. The distinction determines whether Zscaler is positioning itself as a platform for AI agent permissions or simply adding a competitive response to Veza.

Zscaler moved quickly and disclosed almost nothing about price. That silence is itself a signal. Symmetry had roughly $35.7 million in total known funding. Zscaler is a $22 billion company. A large acquirer paying a large multiple for a small DARPA-spinout research team looks different from a large acquirer paying a revenue multiple for a growth business. The deal structure suggests the latter was not on the table. This looks like an infrastructure bet placed before the category is defined, not after it is proven.

Whether that bet is right depends on one question: do AI agents in production enterprise environments need a dedicated access graph, or will the problem be solved inside the agents themselves by people who build the agents? If the latter, Zscaler bought a toll gate nobody will have to pay. If the former, every AI security startup is now either competing with Zscaler or needs to interoperate with it.
