Products & Services
Enterprise SaaS platform for securing agentic, generative, and predictive AI across discovery, supply-chain security, attack simulation, and runtime protection.
Discovers and inventories models, agents, AI workflows, and related AI assets so organizations can identify and manage AI-specific risk.
Scans and assesses models and AI dependencies before deployment, helping detect vulnerabilities, malicious components, and integrity risks.
Automates adversarial testing and red teaming to identify weaknesses in models, agents, and AI applications before deployment.
Market Position
HiddenLayer positions itself as a research-led, end-to-end AI security platform spanning discovery, supply-chain security, adversarial testing, and runtime protection. Its differentiators are model-agnostic and agentless deployment, non-invasive runtime defense, and no requirement for customer data, prompts, algorithms, or weights; competitors and adjacent alternatives include Protect AI, Lakera, Robust Intelligence/Cisco, CalypsoAI, Prompt Security, Mindgard, and Enkrypt AI.

Board of Directors
Founding Story
The founders started HiddenLayer after firsthand experience with an adversarial attack against an AI system. They saw that companies were deploying machine-learning models with vulnerabilities—such as model theft, tampering, and data poisoning—for which conventional security tools offered no purpose-built controls, and set out to create frictionless security for AI.
Business Model
Revenue Model
Enterprise B2B SaaS sold through platform subscriptions and enterprise contracts; the company primarily sells security modules and deployment/support capabilities to organizations, with demo-led sales rather than public self-serve pricing.
