From Assistive to Agentic: The AI Shift That’s Redefining Threat Management

The average enterprise security team manages 40 or more security tools, yet breach dwell times remain around 43 days due to siloed operations and slow manual response. The article argues that the core problem is architectural: security programs were designed for slower threats, but AI-driven adversaries now move at machine speed.

Gartner’s Continuous Threat Exposure Management (CTEM) framework offers a shift from reactive assessments to a continuous cycle of scoping, discovery, prioritization, validation, and mobilization. However, operationalizing CTEM end-to-end has been difficult because tools like threat intelligence platforms, vulnerability scanners, BAS tools, and SIEMs do not communicate seamlessly.

The article distinguishes between assistive AI (which waits for queries and summarizes data) and agentic AI (which autonomously understands context, sets priorities, and executes multi-step workflows across systems continuously). Agentic AI is positioned as essential for matching the pace of modern threats.

For CTEM, three functions must become a closed loop: operationalizing threat intelligence, testing and validating security posture, and mobilizing response. An AI orchestration layer with interconnected agents can automate these workflows while keeping humans in the loop for final decisions. The article highlights Filigran’s XTM One CTEM Assistant as an example of this approach and promotes a live webinar on June 30 and July 2, 2026.
