Cerbos sells an open-source authorization engine that lets an application decide whether a user or service can take an action. The traction is real and capital-efficient: thousands of GitHub stars, named users such as Utility Warehouse and 4G Capital, and a managed Cerbos Hub built on two disclosed seed rounds. Cerbos now markets the same engine to govern AI agents and the MCP servers they connect to, defining and revoking what each agent may access. That mechanism is the one it already sells, so the agent pitch is a new buyer for an existing product, not a new moat. Its durable edge is the cost a customer pays to pull the embedded engine out, which grows as an application scales, while AWS, Auth0, and Okta add fine-grained authorization to their own stacks.
| Description | Cerbos is an authorization company. Its open-source Cerbos PDP and managed Cerbos Hub let engineering and security teams externalize access control from application code, enforcing fine-grained, contextual policies for applications, APIs, and the AI agents and MCP servers those teams run. | [f1] |

| HQ | London, United Kingdom | [f2] |
| Latest funding | Extended seed, $7.5 million, April 2023, led by OMERS Ventures | [f3] |
| Product | What it does |
|---|---|
| Cerbos PDP | Open-source, stateless policy decision point that externalizes application authorization, evaluating context-aware access policies written in YAML and CEL and returning allow or deny decisions. |
| Cerbos Hub | Managed control plane over the Cerbos policy decision point for authoring, testing, distributing, and auditing authorization policies. Sold commercially as the Cerbos Hub + Synapse bundle. |
| Cerbos Synapse | Context layer that assembles real-time identity and resource context from a data fabric and connects APIs, gateways, and infrastructure so authorization decisions stay consistent across systems. |

| AI-Workload Platforms Inference servers, training platforms, vector DB platforms, and the model-loading supply chain. | ||||||
| AI Orchestration Tools Agentic orchestration tools, plus their plugins, skills, hooks, system prompts, scaffolding, harnesses, configuration settings, and MCP clients on user devices. | ||||||
| AI-Generated Code Code produced by AI tools, AI-assisted reviews, AI-generated infrastructure-as-code and tests, and vibe-coded apps that bypass CI/CD. | ||||||
| AI Gateways & Routers MCP proxies and gateways, LLM routers, outbound AI-service traffic, shadow AI egress, and model-registry traffic. | ||||||
| AI Model Model weights, fine-tuning checkpoints, model cards, registries, AIBOM, and the third-party LLMs your enterprise consumes. | ||||||
| Training Data Datasets used for training, fine-tuning, and continued learning. | ||||||
| Runtime AI Data User prompts, inference inputs, RAG content, vector DB content, persistent agent memory, and interaction history. | ||||||
| AI Agent Identities AI agents as non-human principals, plus credentials, keys, permission scopes, service accounts, and delegation chains across agents and tools. |
Cerbos PDP enforces fine-grained, contextual authorization for AI agents and MCP servers, defining what each agent can access before it goes live and revoking that access through policy at runtime. These capabilities are mapped to the AI Defense Matrix. [f4]
