HiddenLayer Raises $100M Series B to Advance Trustworthy AI

HiddenLayer, a prominent player in AI security, has successfully raised $100 million in a Series B funding round led by Delta-v Capital, with participation from notable investors including Ten Eleven Ventures, Morgan Stanley, M12, Microsoft's Venture Fund, and Booz Allen Ventures. This funding announcement was made on September 2, 2026, and is set to enhance HiddenLayer's enterprise platform and security capabilities, particularly in the context of securing agentic, generative, and predictive AI applications.

The funding comes at a critical time as enterprises increasingly face the challenge of securing a rapidly expanding AI attack surface. The rise of autonomous coding agents and foundation models has heightened the urgency for robust security solutions. HiddenLayer's platform is designed to address these vulnerabilities, providing enterprises with tools to safeguard their AI systems throughout their lifecycle. The company has experienced significant growth, with annual recurring revenue increasing more than tenfold over the past year and over 50 new platform customers acquired across various sectors, including finance, pharmaceuticals, and government.

HiddenLayer's strategic focus on enhancing its enterprise platform includes the development of its Agentic Runtime Security capabilities and the introduction of Agent Harness Security. These solutions are designed to secure AI coding agents during runtime, addressing the need for real-time protection as organizations integrate autonomous systems into their operations. According to industry experts, traditional security measures are insufficient for the unique challenges posed by AI, necessitating a dedicated approach to AI security that is embedded within the operational framework of organizations.

The implications of this funding round extend beyond HiddenLayer itself, reflecting broader trends in the market. As organizations increasingly recognize AI as a critical component of their operations—96% of enterprises consider AI essential, yet nearly a third remain uncertain about their exposure to AI-related breaches—there is a growing consensus on the need for specialized security solutions. The investment from high-profile firms signals a commitment to advancing AI security standards and addressing the urgent demand for protection against emerging threats.

In conclusion, HiddenLayer's successful fundraising round positions the company to further develop its innovative security solutions in a rapidly evolving landscape. The backing from prominent investors underscores the critical importance of AI security as enterprises continue to adopt and scale AI technologies. As the integration of autonomous systems becomes more prevalent, the need for comprehensive security measures will likely drive continued investment and innovation in this sector.
