Agentic AI — systems that plan and carry out tasks autonomously on your behalf — is among the hottest topics of 2026. These agents book, buy, write code and run processes without constant human oversight. But every new capability brings a new attack surface.

The problem is that an AI agent has access to real systems and data — and if someone manipulates it, it can act against you using your own permissions.

Where the risks lie

The most insidious attack is prompt injection — malicious instructions hidden in data the agent processes (an email, a document, a web page). The agent takes them as a command and performs actions you never authorized.

The core threats

• Prompt injection — manipulation through malicious input data
• Excessive permissions to access systems and data
• Chained autonomous actions that slip out of control
• Leakage of sensitive data through the agent
• No audit trail — you don't know exactly what the agent did

Secure deployment

AI agents must fall under Zero Trust too: minimal permissions, an audit of every action and clear boundaries. Treat every agent as a privileged user that requires constant oversight and should never have more access than the task demands.
