Cranium Arena is an AI red teaming platform designed to identify security and compliance vulnerabilities in AI systems across an organization's internal and third-party AI supply chain. The platform performs automated, continuous stress-testing of language models and decision engines using agentic simulations. Unlike point-in-time assessments, it runs continuously to surface new vulnerabilities as models evolve. Key capabilities include: - **Automated AI Red-Teaming:** Agentic simulations that expose model weaknesses without requiring manual effort. - **Third-Party Model Assessments:** Extends red teaming to vendor and supplier AI models, allowing organizations to evaluate external AI components against internal standards. - **Continuous Vulnerability Reporting:** Generates updated vulnerability reports on an ongoing basis to keep risk owners informed. - **Built-In Compliance Checks:** Maps findings to established frameworks including NIST AI RMF, EU AI Act, and ISO 42001. - **AI Card Publishing:** Results can be published as an AI Card via Cranium's Trust & Safety Hub for sharing with internal and external stakeholders. The platform is positioned for enterprise use cases where AI is deployed both internally and through third-party vendors, and it aims to support compliance obligations by aligning automated findings to regulatory and standards frameworks.
