Why AI Agents Pose New Security Risks and How to Safeguard Them

What Is an AI Agent? How Does It Differ From Traditional AI?

An AI agent is an algorithmic system that not only makes decisions based on data but also executes actions based on those decisions. Unlike generative AI that creates content, agents perform behaviors. The concept dates back decades in video games and robotic process automation, and today agents are being applied more broadly, though they are not yet AGI.

Security Risks of AI Agents

AI agents introduce several security concerns that can be grouped into two technical risks and one societal risk.

Data Leakage

Agents need to access diverse information sources and interact with multiple services, often transferring data across organizational boundaries. This fluidity makes it difficult to track where sensitive information flows, increasing the chance of unintended exposure.

Lack of Accountability

Accountability issues arise in two dimensions: task execution responsibility and product/legal liability. Agents can remove humans from the responsibility chain, making error tracing and blame assignment hard. Existing legal frameworks provide little clarity; while the EU AI Act seeks to hold organizations accountable, its applicability to rapidly evolving AI agents remains uncertain.

Over‑Enthusiasm Can Amplify Risks

Deploying AI agents for simple, repetitive tasks without careful consideration can introduce unnecessary security vulnerabilities. In many cases, well‑designed APIs or traditional automation tools can achieve the same goals more safely and are easier to test and maintain.

How to Mitigate AI Agent Security Challenges

First, rigorously evaluate whether an AI agent is the right solution for a given scenario; if a reliable API suffices, prefer it. When agents are necessary, embed strong engineering practices: conduct early risk analysis and threat modeling, create extensive test suites that probe for adversarial behavior, and implement control mechanisms (e.g., guardrails) to limit agent actions.

Strategic and Engineering Practices for Safe AI Agents

Adopt a strategic, holistic mindset: view AI agents as one tool among many—combined with generative AI, new APIs, etc.—rather than a universal fix. At the engineering level, start security analysis early in the development lifecycle and continuously test the agent’s behavior to ensure it remains within safe boundaries.
