HiddenLayer, an Austin, Texas-based AI security company, raises $100 million in a new funding round to advance AI runtime security. The company says it will invest in “agentic” runtime security capabilities designed to protect AI systems, including AI coding agents, as they operate and interact with other software.
The PR announcement frames the investment in the context of growing enterprise concerns over the expanding AI attack surface, covering foundation models and newer autonomous agents that write and ship code. SecurityWeek similarly focuses on how the funding supports runtime protections aimed at securing those agentic workflows. Across the two sources, both describe the same core initiative—using the capital to build and scale AI runtime security—while differing mainly in emphasis: PR Newswire highlights broader trust and enterprise adoption themes, while SecurityWeek stresses the specific focus on agentic runtime security.
