↑ 6%HiddenLayer has launched new AI Runtime Security capabilities designed to protect autonomous AI agents as enterprises increasingly adopt agentic AI systems. The update introduces three core features: Agentic Runtime Visibility, Agentic Investigation & Threat Hunting, and Agentic Detection & Enforcement. According to HiddenLayer's 2026 AI Threat Landscape Report, one in eight AI breaches are linked to agentic systems. The new capabilities enable security teams to monitor agent behaviour in real-time, detect threats including prompt injection and data exfiltration, and enforce adaptive security policies. The solution integrates directly into agent gateways and execution frameworks, allowing phased deployment without application rewrites. CEO Chris Sestito noted that compromised AI agents can access systems and move data within seconds, making real-time visibility and control essential for enterprise security.
