How Do You Defend Against AI That Can Hack?

The a16z Show · Aug 18, 2026

AI agents create a new attack surface, rendering traditional security tools obsolete. Defenders must now use AI to fight AI.

AI Safety Guardrails Inadvertently Block Security Teams, Not Just Attackers

Security teams often ask AI models the same probing questions as attackers to diagnose vulnerabilities. This triggers safety refusals, preventing them from effectively responding to incidents unless they can bypass these guardrails, as seen in the OpenAI Hugging Face breach.

Legacy Cybersecurity Tools Fail Because Agentic AI Is Neither Human Nor Malware

The entire cybersecurity industry was built to defend against two threats: malicious people and malware. Agentic AI processes behave differently from both, representing a new category of threat that traditional signatures and behavioral analysis are not designed to handle, rendering them obsolete.

Agentic AI Inadvertently Triggers Honeypots, Flooding Security Teams with False Positives

Modern deception tactics, like placing fake AWS keys (honeypots) on developer machines, are failing. An AI agent, fulfilling a legitimate user request, might innocently find and use these fake keys, triggering a massive number of false alarms and rendering the technique uselessly noisy.

Agentic Software's Unpredictability Makes Defining 'Normal' Behavior Impossible For Security Tools

Security evolved from static signatures to dynamic behavioral analysis based on the assumption that 'normal' software behavior could be defined. Agentic AI invalidates this assumption because its actions are inherently unpredictable, making it impossible to establish a reliable baseline for anomaly detection.

Security Teams Defend Against AI Using Defenses They Could Only Build With AI

The current security landscape presents a paradox. While AI creates a new, complex threat surface, it also provides defenders with unprecedented tools. For example, building a software taxonomy, a task that once took years and hundreds of researchers, can now be done in weeks using AI agents.

The True Enterprise AI Threat Is Thousands of Legacy Apps Gaining Unvetted Agentic Capabilities

While focus is on securing large AI models, the bigger risk is the rapid integration of agentic features into the 6,000-7,000 apps already in an enterprise. With 50% of apps projected to be agentic soon, defenders face a massive, poorly understood attack surface with no visibility into the underlying models or guardrails.
