HiddenLayer sells cybersecurity software built specifically to protect AI models, agents and applications. Its platform discovers AI assets, scans models and their supply chains, tests for adversarial attacks and monitors deployed systems for threats across the AI development and operating lifecycle.
HiddenLayer's AISec Platform helps security and AI teams find models and assets in their environment, check model files and components for vulnerabilities, and test systems against threats such as prompt injection, data poisoning and adversarial manipulation. It also provides runtime protections and monitoring so teams can detect and respond to attacks after AI applications enter production.
The platform is designed for enterprises adopting generative, predictive and agentic AI, and can integrate with existing security workflows or run in cloud, on-premises and air-gapped environments. Its adversarial AI research team informs detection and threat coverage as customers move AI workloads into production.
