Onyx Security provides an agentic AI security platform designed to help enterprise security teams discover, monitor, and govern AI agents operating within their environments. The company's core product, the Onyx Guardian Agent, addresses security risks introduced by AI agents deployed across multiple platforms, including those from AWS, Microsoft, Anthropic, Salesforce, Oracle, and others. The platform covers the full lifecycle of AI agent security through six stages: - Discovery: identifying and cataloging all AI agents in an environment - Governance: establishing compliance frameworks and policy enforcement - Exposure reduction: identifying risks and governance violations - Runtime protection: real-time monitoring and control of agent actions - Incident response: protocols for addressing security breaches - Adoption: enabling broader rollout of controls and protections Key security concerns the platform addresses include AI agents spreading across dozens of platforms without centralized visibility, agents accessing sensitive data without oversight, and agents executing code in environments without restriction. The company cites statistics such as 80% of enterprises exposing sensitive data through agents, 93% of organizations running AI agents with excessive permissions, and 70% of companies being exposed to remote code execution attacks via compromised agents. The platform integrates with existing security stacks, supports BYOC (Bring Your Own Cloud) deployment, and includes built-in SAML and RBAC support. It handles 100+ agent interactions and is compliant with SOC 2, HIPAA, ISO 27001, and GDPR standards. The target market is enterprise security teams managing environments with deployed AI agents.
