What is HiddenLayer?
HiddenLayer sells an AI security platform with four modules: AI Discovery, AI Supply Chain Security (model scanning), AI Attack Simulation (automated red teaming) and AI Runtime Security, which includes AI Detection and Response, agentic and MCP protection and Agent Harness Security for coding agents such as Claude Code, Cursor and GitHub Copilot. The agentic capabilities monitor agent actions, enforce runtime policy across APIs, MCP tools, code execution, communication tools and filesystem operations, and block prompt injection hidden in documents, MCP responses or retrieved context. Documented deployment options include SaaS, Helm-based self-hosting for runtime security, hybrid and disconnected modes and an air-gapped option, with Python, TypeScript and Java SDKs published under Apache-2.0. The company was founded in March 2022, is headquartered in Austin, Texas, and announced a $100 million Series B led by Delta-v Capital in September 2026, following a $50 million Series A in 2023. It is SOC 2 Type II certified, and its AWS Marketplace SaaS listing shows $5,000,000 for a 12-month full-platform contract with private offers available.
- ✓ SOC 2 Type I and Type II badges on the vendor site, with self-hosted (Helm), hybrid and air-gapped deployment modes documented
