Cranium Enterprise is now Cranium ONE. Every product Cranium AI has shipped since 2023 now runs inside one AI Trust Loop: Discover, Observe, Govern, Secure and Prove.

Formerly Cranium Enterprise
↻ Continuously
The runtime engine Cranium AI acquired in May 2026 now works at every stage of the AI Trust Loop. Here is what it does at each one.
Surfaces shadow AI from connected SIEM activity, sorted into AI providers, AI-enabled SaaS, AI web apps and AI inside developer tools.
Records every interaction between your AI tools and the model, including the tool calls an agent makes, in session and event views.
Turn written policy into rulesets. Each safety and security signal gets a Block, Modify or Pass action for every use case.
Enforce mode sits inline on prompts and responses. Cannon runs whole prompt collections to test a profile’s guardrails before they go live.
Explains every verdict from deterministic classifiers, not an LLM judge, so the reason behind each decision is on record.
What each product did when it launched, and the job it does inside Cranium ONE today. Filter by stage, or bookmark a single row.
Cranium AI’s original enterprise platform for mapping, monitoring and managing AI. The AI Card launched in June 2023 as one of its modules.
One platform for end-to-end AI security and governance. Every module now works as part of the AI Trust Loop, across every model, agent and vendor.
Meet Cranium ONE →A container for information about an AI system: how it was built, how it is governed and how it aligns to regulation.
A living, exportable transparency report for each system, mapped to the EU AI Act, NIST AI RMF and ISO 42001. Request, respond and share with vendors and auditors.
Explore Prove →Mapped the AI attack surface, assessed known vulnerabilities and ran AI red-teaming across internal and third-party AI systems.
Red-teaming grew into Cranium Arena™, tested against MITRE ATLAS and OWASP, with Arena Shield™ testing guardrails and exporting hardened configuration. Attack-surface inventory now lives in Discover. Test evidence flows into Prove.
Explore Secure →Detected weaknesses in AI systems that threats could exploit, rated their severity and recommended fixes.
Each assessment ties to an AI Bill of Materials and combines Arena test results, technology CVEs scored by CVSS, and findings from the Adversarial Inputs Detector.
Explore Secure →Launched as an AI discovery tool at scale, finding and labeling AI across enterprise codebases in hours, not weeks.
One of four Discover sensors. It runs detection across every repository your version-control integrations find, then hands AI-positive repos to CodeSensor for an AI Bill of Materials.
Explore Discover →Cranium AI’s code scanner for public and private repositories, built to generate AI Bills of Materials.
Scans GitHub, GitLab, Bitbucket and Azure DevOps repositories and builds the AI-BOM: models, datasets, technologies and infrastructure. Exports to CycloneDX and SPDX, and rescans on every push when webhooks are on.
Explore Discover →The workspace for registering AI systems, self-attesting to compliance frameworks and requesting AI Cards from vendors.
Compliance scoring and ComplianceAgent™ (Beta) power Govern. AI Card requests, responses and My Vendors carry the evidence into Prove.
Explore Govern →Industry hubs where enterprises and vendors share AI standards and evidence in one place.
Publish standards, benchmarks and evidence to private or industry-wide hubs, so teams, vendors and regulators work from the same expectations.
Explore Prove →The agentic AI security company Cranium AI acquired in May 2026. Its CEO, Alex Schlager, is now Cranium AI’s CTO.
Its runtime engine is now Cranium Guardian, and it works across the whole loop: shadow AI in Discover, sessions and events in Observe, profiles in Govern, Enforce mode and Cannon in Secure, and Trace™ explanations in Prove.

Introduced as a new module of Cranium Enterprise.
Attack-surface mapping and AI red-teaming in one solution.
AI discovery across enterprise codebases, at scale.
AI red teaming that extends to the AI supply chain.
AgentSensor™, CloudSensor™, ComplianceAgent™ and Arena Shield™.
Its runtime engine becomes Cranium Guardian.
One team and one platform, introduced at Black Hat USA 2026.
Detect AI™, CodeSensor™, Arena™, Arena Shield™ and the AI Card™ keep their names. They now sit inside a stage of the loop instead of standing alone.
The Public API still answers at api.cranium.ai, with EU and Australia regions. Resources keep their names: Bills of Materials, Arena Models, AI Cards and Vendors.
Every guide still lives at docs.cranium.ai, organized by the areas you already use, from Detect AI to Cranium Guardian.

Cranium Enterprise is now Cranium ONE. It is the same Cranium AI platform, now organized around the AI Trust Loop (Discover, Observe, Govern, Secure and Prove) and covering every model, agent and vendor across the enterprise AI supply chain.
Yes. CodeSensor™ is one of the four sensors inside Discover, alongside Detect AI™, CloudSensor™ and AgentSensor™. It scans your repositories and builds the AI Bill of Materials, and the Public API can still trigger a CodeSensor scan on a BOM.
Its red-teaming and vulnerability work now lives in Secure, through Cranium Arena™, Arena Shield™ and Vulnerability Assessments. The attack-surface inventory it started moved into Discover, and its test evidence feeds AI Cards in Prove.
Cranium AI acquired Aiceberg in May 2026, and its runtime engine is now Cranium Guardian. Guardian works across the AI Trust Loop: shadow AI in Discover, sessions and events in Observe, profiles in Govern, Enforce mode in Secure and Trace™ explanations in Prove.
No. Discover is the first stage of the AI Trust Loop. Detect AI™ is one of the sensors that powers it, finding which repositories contain AI so CodeSensor™ can document what is inside.
Each stage depends on the one before it. You can’t observe AI you haven’t discovered, govern behavior you haven’t observed, or prove controls you never enforced. The loop runs continuously as models, agents and vendors change.
A working session with our team: where your legacy modules live in Cranium ONE, and what Discover through Prove looks like on your own AI.
