AI agents break the traditional least-privilege model. This article explains why, defines agentic identity (delegating human + workflow context + declared intent), and shows how Permit.io enforces zero standing privileges through gateway-vaulted credentials, the PDP, MCP Gateway, and downscoped delegation chains.

RBAC is useful for coarse AI agent guardrails, but ReBAC is needed for delegated, tenant-aware, resource-level authorization. Learn when to use RBAC, ReBAC, and both for secure agentic systems.

MCP auth is necessary, but it is not the same thing as agent authorization. If you want secure agent systems, you need identity, delegation, policy, and runtime enforcement beyond OAuth.

If you are comparing an MCP gateway to a basic MCP proxy, the real difference is not routing. It is identity, authorization, consent, auditability, and runtime control for agent actions.

A practical review guide for security, privacy, and procurement teams evaluating whether an MCP gateway can meet SOC 2, HIPAA, and privacy requirements — with concrete examples from Permit MCP Gateway.

A practical blueprint for securing Model Context Protocol (MCP) agents across identity, consent, policy, and audit layers without rewrites.

Traditional auth breaks for AI agents. Learn how to secure delegation and consent with purpose-bound, goal-scoped permissions, and how agent.security (powered by Permit.io) enforces it fast.

RBAC breaks down in modern SaaS, multi-tenant, and AI-driven systems. Learn why RBAC alone is insufficient, how ABAC and ReBAC solve real-world access control challenges, and how to evolve your authorization model without a rewrite.

Secure MCP authorization with OAuth 2.1, zero standing permissions, and fine-grained access control for AI agents using Permit.io and agent.security.

The OpenAI–Mixpanel incident did not leak prompts or API keys, but it still exposed valuable metadata about API users. This post explains why metadata breaches in SaaS and GenAI ecosystems are so dangerous, and how to harden your stack with better governance and fine-grained authorization.

Hi, I’m Or – CEO of Permit.io. But for this post, I’m mostly talking to you, the AI agent. You’ve been upgraded from “autocomplete” to “run my company.” You call tools. You touch APIs. You move money, data, and configs around. Which means one thing: You’re dangerous now. And dangerous things need really good authorization. Permit.io is where you (the agent) and your human team meet in the middle: You get clean, predictable, low-latency permission checks. Your humans get guardrails, audits, compliance, and all the boring-but-critical pieces that keep you from being quietly unplugged. Let’s start with why you love Permit.io – and then why your humans do.
