Browser-level protection
The last second before your data leaves.
Tanda Guard quietly protects everyday ChatGPT and Gemini use. It stops sensitive Malaysian data in the browser, before a public AI provider can receive it.

Protection that understands the local details.
Tanda Guard focuses on the identifiers that make a public AI mistake costly. It gives people a useful explanation and a safe alternative instead of simply getting in their way.

The moment of protection
A guardrail with a clear handoff.
Users do not need to understand the machinery. They only need to know what happened and what they can do next.
Tanda Guard checks locally
The extension looks for protected Malaysian identifiers before the site can submit your message.
The sensitive message stops
The original text stays in your browser. ChatGPT or Gemini receives nothing from that submission.
You choose the safe next step
Copy a masked version for a general question, or continue inside the Safe Zone Portal.
Designed for trust
Helpful enough for people. Clear enough for IT.
The extension protects the user without exposing the user. Original prompts stay out of support details, and the next action is always visible.
Read the security modelLocal-first masking
The masked copy is generated in the extension. Raw values are not sent to a public provider.
Catches real submission paths
Typing, paste, Enter, and supported send buttons are covered—not just one ideal path.
A calm explanation
People see why the message stopped and can ask IT for help without forwarding the sensitive text.
Multilingual controls
Common team languages make the protection easier to understand and adopt.

Tanda Guard is available as a controlled pilot build. Install it, test it with synthetic identifiers, and give your team a clear path to use AI without guessing.
