HiddenLayer Raises $100 Million for AI Runtime Security

HiddenLayer, an AI security company, raised $100 million to expand its platform that protects AI agents (autonomous systems that can perform tasks with minimal human intervention) from threats throughout their lifecycle. The company plans to focus on runtime security (monitoring and protecting AI systems while they're running) for coding agents and autonomous systems, providing enterprises visibility into AI agent behavior to detect and stop anomalous actions like manipulation and unauthorized use.
