HiddenLayer provides security solutions specifically designed to protect artificial intelligence and machine learning systems. The company was founded in 2022 by security and ML professionals who experienced a real-world adversarial AI attack at Cylance in 2019, where attackers exploited an AI model using inference attacks to evade malware detection.

The company's AISec Platform addresses multiple aspects of AI security including supply chain security, runtime defense, posture management, and automated red teaming. The platform protects against threats such as prompt injection, adversarial manipulation, model theft, inference attacks, bypass attacks, extraction attacks, and supply chain compromise. It is designed to secure agentic, generative, and predictive AI applications.

HiddenLayer's solution operates as a cloud-based software platform that monitors and analyzes the behavior of in-production AI models without requiring access to raw data and algorithms. The company serves organizations across both private and public sectors, including government entities. HiddenLayer has been awarded contracts by the U.S. Department of Defense, including a Phase 2 SBIR contract worth $1.25 million to implement their Machine Learning Security Platform for the Department of the Air Force.

The company maintains partnerships with organizations including Databricks, MITRE, and is part of the NVIDIA Inception Program. HiddenLayer has been recognized by Gartner as a Cool Vendor for AI Security and is backed by investors including M12 (Microsoft's Venture Fund), Moore Strategic Ventures, Booz Allen Ventures, IBM Ventures, and Capital One Ventures.
