HiddenLayer

HiddenLayer is an enterprise AI security company whose AISec Platform protects machine learning models and AI applications across their lifecycle, from supply-chain scanning to runtime detection and adversarial red teaming.

HiddenLayer, founded in 2022 and headquartered in Austin, Texas, provides security purpose-built for AI and machine learning systems. Its AISec Platform spans four core modules: AI Discovery (visibility into AI assets to eliminate shadow AI), AI Supply Chain Security (scanning models for malware, vulnerabilities, and backdoors before deployment), AI Runtime Security (detecting and responding to adversarial attacks in production), and AI Attack Simulation (continuous automated red teaming). The platform is model-agnostic and agentless, deploying without requiring access to raw training data, model weights, or prompts, and adds AI guardrails plus protection for agentic and MCP-based systems. HiddenLayer raised a $50M Series A in September 2023 led by M12 (Microsoft's Venture Fund) and Moore Strategic Ventures, with participation from Booz Allen Ventures, IBM Ventures, Capital One Ventures, and Ten Eleven Ventures.
