Non-human identities in Fortune 500 companies grew 480% in the last six months alone, and enterprises have no visibility into most of them. The moment an AI agent is deployed, it inherits elevated human permissions and moves at machine speed, touching data in seconds that would take a human a career to reach. This invisible layer of the new autonomous workforce is rapidly becoming the fastest-growing attack surface in enterprise security. Until now, there has been no infrastructure purpose-built to govern what agents can see and do, leaving sensitive data, critical systems, and regulatory obligations increasingly at risk. Today at Black Hat 2026, Cyera launched Agent Guardian, built to make every AI agent as visible and accountable as a human employee.
Cyera launched Agent Guardian at Black Hat 2026 to provide visibility, governance, and runtime control for AI agents across enterprise environments.
Non-human identities in Fortune 500 companies grew 480% in the last six months, with most lacking proper oversight and security controls.
Agent Guardian monitors every tool call, database query, and reasoning step beyond just prompts and responses for complete agent accountability.
Cyera Endpoint brings AI guardrails directly to employee devices for local agents like Claude Code and Cursor that operate outside corporate network controls.
The platform covers the full agentic surface including Microsoft Copilot Studio, Salesforce Agentforce, Snowflake Cortex AI, AWS Bedrock, and Vertex AI.
Agent Guardian organizes security around four pillars: Discover, Govern, Protect, and Validate with continuous red-teaming and compliance reporting.
Agents are already inside enterprise systems operating without oversight. The fundamental shift isn't that organizations have more identities; it is that the gap between permission and execution has disappeared. AI agents inherit elevated human permissions and operate at machine speed, creating unprecedented data exposure risks. Cyera's newest products—Agent Guardian and Cyera Endpoint—deliver critical trust infrastructure for the age of autonomous AI, extending the trust layer Cyera is building for the agentic enterprise.
Agent Guardian fills the critical gap between rapid agentic adoption and operational control, organizing the agent security journey around a continuous, systematic operational lifecycle. The Discover capability automatically inventories every AI application and agent running across endpoints, SaaS platforms, and cloud environments, including shadow agents and MCP servers security teams did not know existed, and maps exactly what data each one can reach. The Govern pillar defines what each agent is allowed to do, flags when it drifts from its intended purpose, and continuously audits for overprivileged access and risky configurations. Protect operates inline within the execution path and uses AI-driven policy and content evaluations to intercept dangerous tool calls, block unauthorized data transfers, and quarantine compromised agents before execution. Validate continuously red-teams defenses against prompt injection, jailbreaking, and privilege escalation, and generates audit-ready compliance reports to satisfy frameworks like the EU AI Act.
Agent Guardian enforces policy wherever AI interacts with enterprise data, including through platform APIs, AI gateways, browser extensions, agent framework hooks, and remote scans of employee devices. That last control point has become increasingly important as developers adopt local agents such as Claude Code and Cursor, where activity never crosses a network boundary and traditional security tools have little or no visibility. To add runtime protection to where local activity happens, Cyera also introduced Cyera Endpoint, a lightweight endpoint control that brings Agent Guardian's policies directly to the device. It provides live visibility into sanctioned and shadow local agent activity, classifies and protects sensitive files before they are accessed or leave the machine, and blocks data from reaching unauthorized personal AI accounts, enabling consistent governance across cloud, SaaS, and endpoint environments.
"AI agents have become a new class of enterprise identity. But the fundamental shift isn't that organizations have more identities; it's that the gap between permission and execution has disappeared," said Tamar Bar-Ilan, cofounder and CTO of Cyera. "Agent Guardian and Cyera Endpoint give organizations the visibility and runtime control to govern this new reality, enabling them to accelerate AI adoption without putting sensitive data at risk."
"AI is only as trustworthy as the data behind it," added Mayank Upadhyay, Chief Security & Trust Officer at Snowflake. "Working with Cyera lets Snowflake customers see every Cortex AI agent in use and understand exactly what data it can reach, so they can adopt agentic AI with the same confidence they place in their data."
Cyera covers the full agentic surface, from desktop agents like Claude Code and Cursor to enterprise platforms like Microsoft Copilot Studio, Salesforce Agentforce, and Snowflake Cortex AI, to custom cloud deployments on AWS Bedrock, Microsoft Foundry, and Vertex AI. Whether enterprises are deploying agents built on AWS Bedrock, managing developer agents running on employee devices, or rolling out Microsoft 365 Copilot, Agent Guardian secures the entire agentic surface from one platform, giving security teams the visibility to see every agent, the precision to govern what it touches, and the runtime control to stop it before it causes harm.
