About Cranium

Cranium sells Cranium ONE, one platform for end-to-end AI security and governance, which it describes as infrastructure and LLM-agnostic. Cranium organizes the platform around the AI Trust Loop, five stages that run continuously: Discover, Observe, Govern, Secure and Prove.[1][4][5][6]

Cranium says AI adoption expands what an enterprise has to defend. Its pages name three problem areas: shadow AI, autonomous agents and third-party AI. Cranium says teams adopt models and copilots faster than security can see them, and that agents plan, call tools, read memory and hand off to other agents. Cranium also says an AI supply chain runs through vendors a buyer does not control.[1]

In the Discover stage, Cranium says a buyer gains visibility into every AI model, agent, dataset and vendor across the enterprise and builds one living system of record. Cranium describes automated AI discovery and inventory, and an AI Bill of Materials for each system.[1][10]

In the Observe stage, Cranium says buyers can track, evaluate and understand complex model and agent behaviors, along with token usage and cost efficiency. Cranium describes sessions views, sequence diagrams of agent tool calls and event-level drill-downs. It cites 100+ risk signals and 250+ intent classifications. Cranium says verdicts come from deterministic classifiers, and that Trace shows the samples, labels and relevance scores behind each decision.[1][6][11]

In the Govern stage, Cranium says buyers can define, implement and enforce AI policy, mapped to NIST AI RMF, the EU AI Act and internal standards. Cranium also names ISO 42001 as a mapped framework. Cranium ComplianceAgent automates framework completion with human oversight, and continuous compliance scoring shows where each system stands.[1][12]

In the Secure stage, Cranium says buyers can stress-test models against real-world threats, surface vulnerabilities and apply targeted controls before and after deployment. Cranium Arena is its agent-based red teaming, using MITRE ATLAS, OWASP and Cranium AI threat libraries. Cranium Arena Shield turns findings into auto-generated remediations and guardrails, and re-tests to verify the fix.[1][13]

In the Prove stage, Cranium says buyers can demonstrate compliance posture on demand and share evidence with customers, partners and regulators through real-time Cranium AI Cards and Trust Hubs.[1][14]

Cranium says it fits its controls to finance, life sciences and telecom. Cranium states that it is SOC 2 Type 2 compliant and ISO 27001 certified, and an active member of the U.S AI Safety Institute Consortium (AISIC), established by NIST.[1][2][5][10]
