Your AI agent browses the web. Every page is a risk.
Raw web pages burn tokens. They leak data. They confuse your model. Cookie banners and hidden text create noise. Prompt injections trick your agent. You need a browser agent firewall.
This layer sits between the web and your AI model. It gives your agent a clean view of the page. The goal is simple. Never let raw pages become raw context.
Here is what a firewall controls:
- Page input: Removes ads and banners.
- Sensitive data: Masks emails and API keys.
- Tool actions: Requires approval for risky tasks.
- Cost: Tracks token usage per tenant.
Stop sending the full DOM. It is noisy and expensive. Use a structured page packet instead. Include the URL, title, and visible text. Label the data. Tell the model what is evidence and what is instruction.
A safe workflow looks like this:
- Capture page snapshot.
- Filter noise.
- Mask PII.
- Score risk.
- Send clean packet to model.
- Check action policy.
- Run safe action.
This shift moves safety from the model to the application. The model suggests an action. Your policy enforces the rule. Low risk actions like scrolling run automatically. High risk actions like sending payments need a human.
Start small. Remove noise. Mask data. Gate actions. Turn your demo into a professional workflow.
