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.

Best for: Large enterprises and government buyers that want agent runtime enforcement, red teaming and model scanning from one platform with self-hosted and air-gapped options.
Pros
  • SOC 2 Type I and Type II badges on the vendor site, with self-hosted (Helm), hybrid and air-gapped deployment modes documented
  • Open-source SDKs (Apache-2.0) and public integration repositories on GitHub
  • Independent coverage by TechCrunch of the $100 million Series B, reporting annual recurring revenue in the tens of millions
Things to check
  • No price list on the vendor site; the only public figure is a $5 million annual AWS Marketplace contract
  • The platform bundles model scanning and supply chain security, so buyers wanting only agent runtime controls take on a broader product
