Validaitor is a platform for testing and validating AI models, systems, and agents across security, safety, quality, privacy, and fairness dimensions. It provides automated AI red-teaming and AI pentesting capabilities, running hundreds of tests aligned with OWASP guidance to identify vulnerabilities such as prompt injection, data leakage, jailbreaks, and excessive agency. The platform generates use-case-specific evaluations and test datasets tailored to an organization's AI workflows, rather than relying solely on generic benchmarks. It stress-tests AI systems with adversarial prompts and realistic user interaction scenarios, and measures correctness, consistency, instruction-following, and other performance factors. Validaitor also supports continuous testing, allowing teams to build and maintain test suites that run automatically throughout development and deployment, flagging degradations when models, prompts, tools, or data sources change. For governance and compliance, the platform includes assessments aligned to the EU AI Act and OWASP guidance, and produces reports, findings, risk ratings, and remediation guidance intended to support regulatory and governance review processes. The tool is designed for AI engineers, product teams, red teamers, CISOs, and governance stakeholders involved in building and deploying AI systems.</description> <parameter name="summary">Platform for AI red-teaming, pentesting, and continuous risk validation across AI systems
