HiddenLayer: AI security platform protecting machine learning models and assets from data corruption, model theft, and AI manipulation for enterprises.
HiddenLayer, an Austin, Texas-based cybersecurity firm, provides comprehensive security solutions for AI models and assets, protecting against data corruption, model theft, and AI manipulation. The company secured $50 million in Series A funding in September 2023, led by M12 (Microsoft's venture fund) and Moore Strategic Ventures, one of the largest AI cybersecurity rounds that year. HiddenLayer nearly quadrupled its headcount in 2023 and partners with Microsoft Azure AI, Intel, and Databricks, securing enterprise AI deployments through proactive monitoring. Investors also include Booz Allen Ventures, IBM Ventures, Capital One Ventures, and Ten Eleven Ventures, supporting its platform for Fortune 100 companies in finance, government, and defense. HiddenLayer was founded in March 2022 by security researchers Christopher "Tito" Sestito, Tanner Burns, and Jim Ballard, who discovered the first AI-specific malware.

HiddenLayer is a technology company specializing in security for artificial intelligence (AI), operating at the intersection of cybersecurity and AI industries. It provides an AI security platform—called the AISec Platform—that protects machine learning models and AI applications from adversarial attacks such as prompt injection, model theft, and supply chain compromises. The platform serves enterprises and public sector organizations by safeguarding proprietary AI models without requiring access to raw data or adding complexity. HiddenLayer’s solutions enable organizations to reduce risk, ensure compliance, and confidently adopt AI technologies[1][2][3][6].
Founded in 2022 and based in Leander, Texas, HiddenLayer was established by a team of cybersecurity and machine learning veterans motivated by the need to protect AI systems from emerging threats. The company emerged after witnessing AI attacks that exposed vulnerabilities in AI models, inspiring the creation of a security platform tailored specifically for AI. Early traction included recognition as a Gartner Cool Vendor for AI Security and strategic backing from prominent investors such as Microsoft’s M12, IBM Ventures, and Booz Allen Ventures. This foundation reflects a blend of deep technical expertise and industry-leading research[1][2][3][5].
HiddenLayer is riding the critical trend of AI security, a rapidly growing field driven by the widespread adoption of AI technologies across industries. As AI models become integral to business operations, their vulnerabilities to sophisticated attacks pose significant risks. The timing is crucial because AI adoption is accelerating globally, and regulatory/compliance pressures are increasing. HiddenLayer’s platform addresses these market forces by enabling organizations to deploy AI securely, thus fostering trust and broader AI adoption. Its partnership with Microsoft to protect Azure AI exemplifies its influence in shaping secure AI ecosystems and advancing industry standards[2][5][6].
Looking ahead, HiddenLayer is positioned to become a foundational player in the AI economy by expanding its platform capabilities and deepening integrations with major cloud providers and enterprises. Trends such as the rise of generative AI, autonomous agents, and increasing regulatory scrutiny will shape its journey. The company’s ability to innovate in AI threat detection and response, while maintaining ease of use and privacy, will be critical to scaling its impact. As AI security becomes a standard requirement, HiddenLayer’s influence is likely to grow, reinforcing its role as a pillar of secure AI adoption globally[5][6][7].
