CAIN-42 CAIN StudioThe niche: data-leak prevention for AI agents
Any company whose agents read outside content and can also see private data and send messages: support, sales, coding, email assistants.
Why this niche exists now
- The lethal trifecta became a widely cited way to explain agent data leaks in 2025.
- Several real incidents in 2025 followed this exact pattern.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| Prompt filters | Look for bad words, not the combination. |
| Remove one leg entirely | Often removes the agent's usefulness. |
What makes Lethal Trifecta Guard different
- Checks the combination, not keywords.
- Recognises your data in outgoing traffic.
- Normal work allowed.
How big is the opportunity?
Do not quote market-size statistics on a call. Most published figures are surveys or vendor estimates, and a smart buyer will ask for the source. Size the opportunity per prospect instead, with these questions:
- Do your agents read outside content?
- Can they see private data and send messages?
If the honest answers are "no" or "not yet", they are not a buyer today. Note it and move on; that is good selling, not failure.

Any company whose agents read outside content and can also see private data and send messages: support, sales, coding, email assistants.
Lethal Trifecta Guard blocks the moment an AI agent session could read attacker text, see private data and send it out, all at once.
Practise saying this out loud until you can do it without reading. Then say it in your own words.
