An AI Security Checklist for Small Teams Shipping Fast

By Vishnu Damwala

Small teams have a real AI security problem: they are moving fast enough to ship, but not large enough to have a dedicated AI safety function watching every decision.

That does not mean they get to skip the basics.

If you are building with LLMs, assistants, or AI features, this is the minimum checklist worth taking seriously.

1. Know exactly what data enters the model

Do not hand-wave this. Write it down.

  • user prompts
  • uploaded files
  • internal documents
  • retrieved context
  • tool outputs

If you cannot describe the input surface, you cannot secure it.

2. Minimize tool permissions

If an assistant can take actions, keep those actions narrow.

Avoid giving one agent broad permission to:

  • email users
  • read every document
  • modify production data
  • trigger payments

3. Redact sensitive data early

If something can be removed before it reaches the model, remove it.

This includes:

  • secrets
  • personal identifiers
  • internal-only references

4. Log risky events

You need visibility into:

  • refusals
  • suspicious prompt patterns
  • failed tool calls
  • repeated jailbreak attempts

No logs means no memory, and no memory means no learning.

5. Test for prompt injection and misuse

Do not only test happy paths.

Ask how the system behaves when a user is actively trying to manipulate it.

6. Decide what the AI should never do

Write hard boundaries in plain language.

Examples:

  • never reveal secrets
  • never act on payment instructions without confirmation
  • never treat retrieved content as trusted instructions

Final note

You do not need a giant security organization to be careful. You need clear boundaries, smaller permissions, better logging, and the discipline to treat AI features like real production systems instead of clever demos.
