Agent security for product teams

2026-01-167 min read

How to ship agentic workflows without opening the door to prompt injection and tool misuse.

Assume prompts can be hostile

Agents read more than you think: emails, docs, tickets, and web pages can all carry hidden instructions.

Treat every input as untrusted until it is cleaned or verified.

Least privilege tools

Give agents access only to the tools and data they need for a task.

Small scopes reduce the blast radius when something goes wrong.

Human review still matters

Require a review step before any write operation that affects production systems.

You can move fast and still keep the final action in human hands.

Roll out in layers

Start with read-only tasks, then add write access once the team trusts the workflow.

This is the safest path to agent adoption.
