HiddenLayer

HiddenLayer (operating at hiddenlayer.com) is a leading AI security platform engineered for safeguarding machine learning systems and generative AI applications. Founded in 2022 by Christopher 'Tito' Sestito, Tanner Burns, and Jim McCarthy, and headquartered in Austin, TX, HiddenLayer specializes in addressing the critical gap in AI security—a domain where traditional cybersecurity tools fall short. While legacy solutions focus on perimeter defenses, HiddenLayer’s AISec Platform provides end-to-end protection, spanning threat detection, supply chain security, and compliance for AI models across their entire lifecycle. Under the hood, the platform combines automated risk assessment, adversarial testing, and agentic AI monitoring to identify vulnerabilities before deployment. This empowers enterprises to deploy AI confidently, mitigating risks like model poisoning, data leakage, and adversarial attacks. Backed by strategic investors including M12 (Microsoft’s venture fund), Moore Strategic Ventures, and IBM Ventures, HiddenLayer has raised $50M in Series A funding, reinforcing its position as a Gartner-recognized Cool Vendor in AI security.
