01 Why Cranium

Every AI platform.
One unbiased referee.

You run models from more than one maker, agents on more than one framework, and AI inside vendors you never built. Cranium ONE is the independent platform that secures all of it, end to end — and proves it to your board.

  • Bring your own AI
  • Independent
  • End to end
  • Board-ready proof
Trusted by companies in the Fortune 10

Some of the world’s largest telecom carriers and banks already run their AI through Cranium.

The enterprises with the most at stake don’t pick a side. They pick a referee.

02 Bring your own AI

We don’t sell a model. So we secure every one.

Your teams pick the right model for each job and switch the day a better one ships. Cranium ONE works across all of them, so your security never depends on whose AI you chose.

i.

Every model, found

An AI-BOM generated straight from your repos — models, datasets, infrastructure and system prompts, whoever built them. Export it as CycloneDX or SPDX.

ii.

Every agent framework

AgentSensor inventories agents built on LangGraph, CrewAI, OpenAI Agents, Amazon Strands, AutoGen and smolagents — with their MCP servers and tools.

iii.

Every LLM, one policy

Guardian inspects the traffic between your apps and the LLM behind them, then blocks, modifies or passes each prompt and response. Same policy, any provider.

03 Independent

A fair game needs an outside ref. So does your AI.

When the company grading your AI also sells you the model, the cloud or the security suite, the referee is wearing a jersey. And across the market, AI security keeps getting bought up and bolted onto bigger platforms.

Cranium stays independent. No model to promote, no cloud to fill, no suite to upsell — one job: an honest verdict on every AI you run.

No model to sell

We never steer you toward a provider. Which AI you run stays your call.

No cloud to fill

Works with the stack you already have. No rip-and-replace, no lock-in.

No suite to upsell

AI security and governance is the whole company — not a feature on someone else’s firewall.

No LLM as the judge

Guardian’s verdicts are deterministic, and Trace™ shows exactly why each one fired.

04 Truly end to end

Most tools cover a slice. Cranium covers the loop.

Governance platforms write policy they can’t enforce. Security tools stop attacks they can’t prove they stopped. Agent tools watch agents and miss the models and vendors behind them. Cranium ONE runs every model, agent and vendor through the whole loop.

05 Proof, not promises

Discover it. Secure it. Prove it to the board.

Stopping threats is half the job. Your board, your regulators and your customers ask a harder question: can you prove it? Cranium turns everything the loop sees into evidence — living AI Cards, continuous compliance scoring and Trust Hubs you share on your terms.

  • Every model, agent and vendor accounted for.
  • Compliance proven in seconds, not scrambled.
  • AI shipped faster — guardrails are continuous, not a gate.
  • Evidence in hand for the board and the regulator.
