2022HiddenLayer secures artificial intelligence systems by discovering, hardening, and monitoring models against attacks across their lifecycle.
HiddenLayer's patent portfolio covers adversarial detection, model protection, and AI threat analysis, with 39 granted and 65 pending patents reported in September 2026. Its customer base includes United States defense and intelligence agencies and a frontier model provider whose products serve more than 700 million weekly users.
The research team published an adversarial prompt engineering taxonomy and contributes to CISA's Joint Cyber Defense Collaborative, MITRE, NIST, OWASP, and OpenSSF working groups. That standards participation gives the company early visibility into the AI-security requirements enterprises will be asked to meet.

Gartner projects enterprise spending on AI security products of $2.83 billion in 2026, an 83 percent increase over 2025, rising to roughly $4.78 billion in 2027. Demand is pulled forward as enterprises deploy agentic systems faster than existing security tooling can inspect them.
Consolidation is already underway, with Cisco acquiring Robust Intelligence, Palo Alto Networks acquiring Protect AI, and Check Point acquiring Lakera. Independent competitors including Noma and Zenity have each raised more than $100 million, so HiddenLayer competes against both platform incumbents and well-funded specialists.

The platform covers four areas: AI discovery, which inventories the models and agents an organization is running; AI supply chain security, which validates model integrity before deployment; AI attack simulation, which probes deployed systems the way an adversary would; and AI runtime security, which detects attacks against models in production.
A professional services practice sells alongside the platform and delivers red teaming engagements, AI risk assessments, and security training and certification. The platform is model-agnostic and agentless, and is deployed by large enterprises and United States federal agencies.
