Ory Agentic AI vs Tesseral: 2026 Comparison

Enterprise security teams deploying autonomous AI agents need Ory Agentic AI because it's the only IAM platform purpose-built to authenticate and authorize agents with task-specific restrictions, not retrofitted from human identity tooling. The Model Context Protocol support and Google Zanzibar-inspired authorization model let you enforce least-privilege access at the agent level, which NIST CSF 2.0 Identity Management coverage confirms, and the headless API-first architecture means no UI friction when agents need to validate themselves at runtime. Skip this if your agents are still running unmediated or if you need identity solutions that also handle workforce access control in a single pane; Ory deliberately focuses on the agent authentication problem.
