HiddenLayer

HiddenLayer is a pioneering AI security platform that specializes in protecting machine learning models from adversarial attacks, model tampering, and supply chain threats. Founded in 2022 and headquartered in Austin, Texas, the company has rapidly established itself as a first mover in the emerging AI Security Posture Management (AISPM) category, attracting significant venture capital backing from investors including M12 (Microsoft's Venture Fund), Moore Strategic Ventures, and Booz Allen Ventures. The platform provides continuous monitoring and protection for ML models across their entire lifecycle, from development through production deployment. HiddenLayer's core capabilities include automated model scanning that detects adversarial manipulation, model poisoning, and evasion attacks before they can compromise AI systems. The platform's Model Scanner analyzes trained models for embedded vulnerabilities and backdoors, while its runtime protection layer monitors inference pipelines in real time to identify and block adversarial inputs. The company supports protection for a broad range of model architectures including deep learning, gradient-boosted decision trees, and large language models, making it applicable across diverse enterprise AI deployments. The platform integrates with major MLOps and cloud environments, allowing security teams to gain visibility into their organization's entire AI model inventory and assess the security posture of each model. HiddenLayer provides detailed risk scoring, vulnerability reports, and remediation guidance that align with frameworks such as the NIST AI Risk Management Framework, OWASP ML Top 10, and MITRE ATLAS. This makes it particularly valuable for organizations operating in regulated industries that need to demonstrate robust AI security controls. HiddenLayer targets mid-market and enterprise customers, with particular strength in financial services, healthcare, and defense sectors where model integrity is critical. The company's research team actively publishes threat intelligence on emerging AI attack vectors, contributing to the broader understanding of AI security risks. While the AISPM category is still nascent and HiddenLayer has a limited track record compared to established cybersecurity vendors, its focused approach to AI-specific threats positions it as a key player in the rapidly growing AI security market.
