HiddenLayer

HiddenLayer is an enterprise AI security platform that targets agentic, generative, and predictive AI applications across their lifecycle. It combines four modules: AI Discovery, AI Supply Chain Security, AI Attack Simulation, and AI Runtime Security. HiddenLayer says the platform is model-agnostic, agentless, and requires no training data.

What It Is

HiddenLayer is a security platform built specifically for AI systems rather than retrofitted from traditional cybersecurity tools, according to the vendor. Security teams, AI leaders, and application developers use it to find AI assets, check models before deployment, test defenses, and monitor production AI for attacks.

How the Platform Modules Work

• AI Discovery builds an inventory of AI applications, models, and assets in an environment, including shadow AI.
• AI Supply Chain Security analyzes models for malware, vulnerabilities, backdoors, and unknown components before they reach production.
• AI Attack Simulation continuously simulates real-world attacks, including red teaming, to uncover weaknesses early.
• AI Runtime Security acts as a firewall that monitors, detects, and responds in real time to adversarial threats on agentic and generative AI applications.

Use Cases and Integrations

HiddenLayer organizes its offering around model scanning, red teaming, AI guardrails (policies against prompt injection and data leakage), agentic and MCP security, and agent harness security for AI coding agents. It lists pre-built integrations with CI/CD, MLOps, data pipelines, and SIEM/SOAR tools, including Databricks, AWS, Azure, GCP, Splunk, and Microsoft Sentinel. Solution pages target CISOs, AI leaders, and developers, and industries such as financial services, technology, healthcare, and US federal government.

Getting Started

Access is through a demo request. The vendor says demos run 30-45 minutes as a live walkthrough tailored to the organization's AI use cases; they do not include live red teaming, which is available through a separate AI Security Services engagement.
