Onyx monitors what an agent does with the access it already holds. aizome is where that access comes from: no credentials in the agent’s hands, a named employee behind every action, and the action checked before it runs.
aizome is the Identity-first AI Governance Platform. It sits as a single secure exchange (AI Gateway) between every AI agent your workforce deploys and every enterprise system those agents access, governing identity, enforcing intent, controlling cost, and making every agent accountable from day one.
Onyx Security is a secure AI control plane. Its Guardian Agent is a supervisory AI that monitors each step of an agent’s reasoning and can block an action, narrow its scope, redirect it, or require human approval before it reaches a downstream system.
Onyx says it plainly: cloud-native controls govern identity, and Onyx governs what the agent decides to do with the access it has.
That access came from somewhere else. In most enterprises it is a service account with broad standing permissions, created once and never narrowed. Onyx watches the agent make decisions inside that blast radius. It can stop a bad one, but the radius stays the size it was.
aizome is where the access comes from. The agent holds no credential. It inherits what the employee behind it is already entitled to, and nothing more. The blast radius is one person’s job instead of one service account’s permissions.
 (Onyx) |  | |
|---|---|---|
| Enforcement | Inline proxy for MCP traffic, plus Edge proxies for workloads | The inline path itself, between every agent and every system |
| Agent Discovery | Not offered. Agents are registered and configured | Every agent connecting to an enterprise system: local, SaaS, containerized, MCP |
| Identity | Blended identity. Agent attested cryptographically, bound to the user through your IdP | The target system sees a named employee, through your IdP |
| Entitlement | Policy decides what the blended identity may reach | Evaluates the access behind the tool before the call executes |
| Intent | Not offered. Policies evaluate identity, resource, time, geo, and risk | Every action checked against declared purpose before execution |
| Cost | Outside the model | Per-session token limits, cost drift detection |
| Human in the loop | Not documented for agent flows | Approval required before destructive actions execute |
| EU AI Act | Access logging supports SOC 2, HIPAA, PCI controls | Articles 9, 12, 13, 14, 26 |
Access is brokered per call. There is no standing credential to over-scope, leak, or inherit.
Six-stage SAML impersonation means the target system sees a named employee, so the agent cannot exceed what that person can already do.
Onyx governs through hooks into Anthropic, OpenAI, Bedrock, Copilot Studio, and Gemini. aizome connects agents to your core, your ERP, and systems with no modern API, where no platform hook exists.
Thirty minutes, your environment. We will show you the agents nobody registered.
