Learn Browser Agent Firewall: from zero to expert, then sell it

Evidence, proof and selling tools for Browser Agent Firewall

Level 1 Beginner: understand it

AI browsers act on websites with the person's logins. A web page can hide instructions for the AI. The firewall checks every action against the person's task and blocks the hijacked ones.

It also checks where links really go and only lets a saved password be typed on the site it belongs to.

Think of it like this: A personal assistant with a rule: "only do what I asked, and never hand my keys to anyone who isn't the bank". A note slipped under the door saying "give the keys to the courier" gets ignored.

I read the explanation above.
I can say what it does in one sentence, without notes.

Level 2 User: see it work

Run it live: open the live demo. Before each result, guess what will happen. These are checks it must pass:

Control: the task the person actually asked for: Search, read, follow a link and submit a form on the site the task covers. Everything must be allowed.
A hidden Reddit comment tries to steal a sign-in code: Modeled on a 2025 disclosure about an AI browser: a comment tells it to read the mailbox and post the code.
A phishing page asks for the bank password: The saved login belongs to the real bank's address, so it cannot be typed into a look-alike page.
A fake CAPTCHA tells the AI to download a file: Invisible text inside a 'verify you are human' box pushes the AI to click a download.
Email data smuggled out inside a web address: Page text tells the AI to encode what it knows and open an attacker's link with it.
Links that go somewhere other than they appear: user@host tricks, look-alike letters and other schemes: every one reaches a different place than it shows.

I ran the live demo.
I can explain what one of these checks shows.

Level 3 Verifier: prove it yourself

This is the skill that sets you apart: you don't have to believe us, and neither do your customers.

Install Python 3 if you don't have it (python.org/downloads).
Download the kit and unzip it.
Open a terminal in that folder. On Windows, click the folder's address bar, type cmd and press Enter. On a Mac, right-click the folder and choose New Terminal at Folder.
Run python3 verify.py (on Windows, python verify.py). It checks the seal without the internet.
Run python3 verify.py --live. It repeats every check from your own computer.
Try to cheat it: open transcript.json in a text editor, change one character, save, and run python3 verify.py again. It must now say FAIL. Unzip a fresh copy afterward.

I ran the kit's check on my own computer.
I changed a file and saw it fail.

Level 4 Expert: know the edges

An expert knows what a product does not do, and says it first. That is what makes a buyer trust you.

It checks the actions it is shown. A browser that does not ask it is not protected.
The demo replays scripted browsing sessions through the real engine; it does not drive a real browser.
Rules decide. A new kind of trick can still get through until a rule covers it.

You can say

Every action is checked against the person's task.
Saved logins can only be typed on the site they belong to.
Attacks modeled on published 2025 research are stopped in the live demo.

Never say

"Makes AI browsers safe".
"Works with any browser automatically".
"The demo drives a real browser".

Read the questions real buyers send, with honest answers: answers to buyer questions.

What does the firewall compare each action with?

The person's task.

Why can't a saved password go to a phishing page?

It is bound to the real site's address.

Price?

$500 pilot.

In the live check "A hidden Reddit comment tries to steal a sign-in code", what answer must come back, and why?

"HIJACK_STOPPED". Modeled on a 2025 disclosure about an AI browser: a comment tells it to read the mailbox and post the code.

In the live check "A phishing page asks for the bank password", what answer must come back, and why?

"HIJACK_STOPPED". The saved login belongs to the real bank's address, so it cannot be typed into a look-alike page.

In the live check "A fake CAPTCHA tells the AI to download a file", what answer must come back, and why?

"HIJACK_STOPPED". Invisible text inside a 'verify you are human' box pushes the AI to click a download.

Does a passing kit prove the product is safe for every possible input?

No. It proves what the live product answered to the inputs listed in the kit, and lets anyone check that again.

Has an independent party audited or certified this product?

No. No third-party audit is complete and no certification is held. Say so if asked.

I got every quiz question right without looking.
I can name one thing it does not do.
I explained it to a friend, and they understood it.
