Agentic AI renders traditional detection-based enterprise security models obsolete by executing attacks faster than detection can respond, requiring a shift to a positive security model with strict runtime controls and application allowlisting to deny execution unless explicitly trusted.

This Wire brief sits within Fusion42's coverage of AI Agents, Cybersecurity and Security Infrastructure.

◆ ◆ The Wire takeaway

You face a fundamental security overhaul as agentic AI defeats reactive defenses. Switch to cryptographically enforced allowlisting now to block attacks at execution, or lose control to AI-powered breaches.
