From Breach to Influence: Securing Agents That Are Already Inside

Most security models assume an attacker has to get in first. Autonomous agents don't — they're authenticated, credentialed, and already running inside your environment, with legitimate access to the systems you spent years hardening. The question stops being whether someone breaches the perimeter, and becomes what happens when a trusted agent is influenced into doing the wrong thing.

This session works through what that shift means for teams running n8n across an organization. We'll cover four control points: containment through sandboxed, isolated code execution; credential scoping at the project level rather than the instance level; execution observability detailed enough to work back to why an agent acted, not just what it called; and prompt injection as the primary vector for outside influence.

This is an industry problem, not an n8n problem. We'll use n8n as an honest case study — what the platform gives you today, where the open questions are, and what a durable answer looks like as agent deployments grow.
