HiddenLayer

Application

Agent Harness SecurityApplication

Protects the orchestration layer connecting AI coding agents to tools, memory, files and enterprise systems, detecting agentic-specific threats like memory poisoning and prompt injection with platform-aware controls for Claude Code, Cursor and GitHub Copilot.

HiddenLayer AI Attack SimulationApplication

Runs adversarial attacks against a customer's own models to find where they break before an attacker does.

HiddenLayer AI DiscoveryApplication

Inventories every model, agent and AI workflow running in an organisation, so security teams know what exists before defending it.

HiddenLayer AI Runtime SecurityApplication

Watches models in production and blocks attacks against them as they happen.

HiddenLayer AI Supply Chain SecurityApplication

Scans models an organisation builds, buys or borrows for tampering and malicious content before they reach production.

Platform

HiddenLayer AI Security PlatformPlatform

Security platform purpose-built for AI systems: discovers models and AI supply chains across an organisation, simulates attacks against them, and detects runtime abuse such as model theft, data poisoning and adversarial inputs.
