What is Cranium?
Cranium is an end-to-end AI Security, Governance, and Agentic AI Platform designed for enterprise AI ecosystems. It helps organizations gain visibility into all AI systems (internal and third-party), identify AI security risks, and demonstrate internal and third-party AI compliance. The platform automatically scans environments to detect Shadow AI, generates AI Bills of Materials (AI BoM), and performs automated red teaming to simulate adversarial attacks before attackers can exploit vulnerabilities.
Key features include Cranium Detect AI™ for discovering Shadow AI across internal environments, CodeSensor™ for scanning source code to detect models/datasets/AI packages, CloudSensor™ for cloud security monitoring, and AgentSensor™ for visibility into AI agents and their tool invocations. The platform also includes Cranium Arena™ for automated agent-based red teaming, Cranium Arena Shield™ for automatically applying mitigations, and Cranium ComplianceAgent™ for streamlining compliance with EU AI Act, NIST AI RMF, and ISO frameworks. Cranium produces AI Cards—stakeholder-ready transparency reports—and enables creation of AI Trust Hubs for sharing governance standards across teams and partners.
Cranium is built for cybersecurity teams, data science teams, security and risk teams, and enterprises in highly regulated industries like financial institutions. It serves organizations that are builders and/or consumers of AI, enabling complete security, compliance, and trust across the entire AI supply chain. The platform is particularly valuable for companies needing to map, monitor, and manage AI/ML environments against adversarial threats without interrupting how teams train, test, and deploy AI models.

Frequently asked questions about Cranium
What is AI Operational Governance?
AI Operational Governance is the implementation of tools, policies, and processes to manage AI systems across their lifecycle—ensuring security, compliance, and performance. Cranium's platform is built for the speed, complexity, and scale of enterprise AI ecosystems, helping organizations ensure that as AI systems grow smarter, AI guardrails grow stronger.
What is Shadow AI?
Shadow AI refers to models, tools, or datasets used without IT or compliance approval—often embedded in third-party products or built by internal teams without oversight. These systems pose security, compliance, and governance risks. Cranium helps detect and manage them through automated scanning.
How does Cranium discover shadow AI?
Cranium's CodeSensor, Detect AI, and CloudSensor tools scan codebases, internal environments, and cloud configurations to surface undocumented or unapproved AI systems. Detect AI scans across internal environments to reveal Shadow AI, CodeSensor scans source code to detect models/datasets/AI packages, and CloudSensor monitors cloud environments for security alerts.
Which compliance frameworks does Cranium support?
Cranium maps to the EU AI Act, NIST AI RMF, ISO, and other emerging global regulations. The Cranium Compliance Scoring agent provides regulatory alignment with these frameworks, and ComplianceAgent™ streamlines compliance framework completion with intelligent automation and document-aware response generation.
Is Cranium deployable in highly regulated industries?
Yes. Cranium's platform is already used by financial institutions and enterprises with strict regulatory requirements. The platform enables organizations to gain visibility, security, and compliance across their AI and GenAI systems while operating in environments with strict compliance needs.
How can I get started with Cranium?
You can request a demo or contact Cranium's team at [email protected] to explore your AI governance readiness. A 30-day free trial is available to explore Cranium's capabilities. You can also download the free Adversarial Inputs Detector IDE plugin from Visual Studio Code Marketplace or Open VSX Registry.
What is Cranium Arena™ and what does it do?
Cranium Arena™ performs automated, agent-based red teaming by simulating adversarial attacks on AI models using automated and manual penetration testing. It integrates live threat feeds from MITRE ATLAS, OWASP, and Cranium libraries to proactively identify vulnerabilities before attackers can exploit them, and automatically applies remediations through Arena Shield™.
What are AI Cards and how are they used?
AI Cards are stakeholder-ready transparency reports produced by Cranium that record model purpose, data provenance, and risk posture. They are part of Cranium's Verify capability that translates governance frameworks into action by generating attestations, scoring compliance, and creating model-specific transparency reports for sharing with third parties, clients, and regulators.
What is Cranium AgentSensor™?
Cranium AgentSensor™ provides organizations deep visibility into the agentic layer of their applications. It automatically detects AI agents, the tools they invoke, and even other agents in their networks by scanning codebases. This lets security teams understand not just the presence of agents, but the full ecosystem of interactions they create.
What is Code Sensing and how does it work?
Code Sensing uses state-of-the-art AI to meticulously scrutinize your codebase to uncover the use of AI libraries, models, and datasets. It enables creation of your AI Bill of Materials (AI BoM) by connecting to and scanning code repositories, automatically identifying datasets, models, and libraries used to build AI systems, and helps identify vulnerabilities in AI infrastructure.
