CAIN-42 MCPGateThe niche: security for AI browsers and computer-use agents
Companies whose staff use AI browsers or browser agents, and companies building browser agents for customers.
Why this niche exists now
- Several AI browsers and browser agents launched in 2025.
- Researchers published multiple hijacks of them in the same year.
- These agents act with the user's real logins, so a hijack is a real account takeover.
What people use today, and where it falls short
| What teams do today | Where it falls short |
|---|---|
| Trust the browser maker's safeguards | Safeguards inside the AI can be talked around by page text. |
| Ban AI browsers | Staff use them anyway. |
| Watch the agent | Defeats the purpose of automation. |
What makes Browser Agent Firewall different
- Checks actions, not just words.
- Knows where each saved login belongs.
- Lets the real task finish.
- Rules decide, not an AI.
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Do not quote market-size statistics on a call.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 staff use AI browsers?
- Are you building a browser agent?
- What accounts are logged in on those browsers?
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.
Explain the niche in 30 seconds
Companies whose staff use AI browsers or browser agents, and companies building browser agents for customers.
Browser Agent Firewall stops an AI browser from doing what a web page secretly told it to, while still doing what the person asked.
Practise saying this out loud until you can do it without reading. Then say it in your own words.

Sell it together with
Buyers rarely have just one problem. When this product fits, these often fit too:
| Product | Why it goes together |
|---|---|
| SurfGuard | reviews a browser agent's whole plan first |
| APPROVAL | a person approves risky steps |
| Black Box flight recorder | records what the browser did |
Rule: open with one product. Mention a second only after the first is agreed.
