The Mythos Moment: Enterprises Must Fight Agents with Agents

The Mythos Moment: Enterprises Must Fight Agents with Agents argues that the rapid adoption of agentic AI, such as Claude Mythos, could enable attacks to be discovered and executed at scale with minimal human intervention, prompting a shift to autonomous, AI-driven defence. It notes a 1,500% rise in discussion about the malicious use of AI, suggesting agentic frameworks are already being operationalised, and warns that discovery automation will drive more zero-days and newly disclosed CVEs into organisations.

To counter this, the piece calls for a new security architecture built on three pillars: visibility, context, and autonomous control, emphasising a unified network view and real-time, context-rich intelligence. It describes agentic defenses that operate at machine speed, including a same-day vulnerability protection agent and a zero-day protection agent, designed to close the gap between CVE publication and remediation.
