Browser & Computer-Use Agents

How it works

How a browser agent works

The agent receives a task and opens an isolated browser session. It reads the screen through screenshots and page structure, acts by clicking, typing and navigating, then verifies the result and hands back data plus a recording of what it did.

Safety by design

Isolate every session, keep credentials out of prompts, limit which sites the agent can visit and require human confirmation for payments, submissions and deletions.

AWS, Azure and Google Cloud compared

What makes each cloud different

Design decisions that matter

1. 01Prefer APIs when they exist

   Browser automation is the fallback.

2. 02Isolated session per task

   No shared cookies or state.

3. 03Allow-list sites

   The agent goes only where it should.

4. 04Human confirmation for risky steps

   Payments, submissions, deletions.

Common mistakes we see

• Passwords in prompts. Credentials leak into logs and models.
• Unrestricted browsing. Malicious pages can inject instructions.
• No recording. Nobody can check what the agent did.

A practical 30-day plan

1. Week 1

   Pick one portal-based task without an API.

2. Week 2

   Build the agent in an isolated browser.

3. Week 3

   Add credentials vaulting and site limits.

4. Week 4

   Pilot with human confirmations and review recordings.

How NTS helps

NTS builds browser and computer-use agents on AWS, Azure and Google Cloud for portal-heavy processes, with isolation, credential security and human-in-the-loop controls designed in.

How we work with you

1. 1Assess

   A focused review of your browser and computer-use agents across AWS, Azure and Google Cloud. We look for the gaps we find most often: passwords in prompts, unrestricted browsing and no recording.

2. 2Design

   A target architecture and roadmap built on the decisions that matter most: prefer APIs when they exist, isolated session per task, allow-list sites and human confirmation for risky steps.

3. 3Build

   Hands-on delivery alongside your team. We pick one portal-based task without an API, build the agent in an isolated browser, add credentials vaulting and site limits, and finally pilot with human confirmations and review recordings.

4. 4Run and improve

   We monitor sessions, fix breakages when interfaces change and expand to new tasks.

Why teams choose NTS for browser and computer-use agents

• APIs first

  We use computer-use agents only where APIs do not exist.

• Safety through isolation

  Agents run in sandboxes with limited access.

• Humans stay in control

  Sensitive steps always need approval.
