BROWSER-BASED AI DLP

Sensitive data stays inside your company.

PromptGuard stops sensitive content before employees accidentally send it to ChatGPT, Gemini, Copilot, or Claude. Detection runs directly in the browser.

BEFORE SUBMISSION

Protection at the right point.

PromptGuard intervenes where sensitive data is entered into a supported AI chat—before it leaves the company.

Checks directly in the browser

Passwords, IBANs, API keys, and other sensitive patterns are checked locally before submission.

Policies for the whole team

Companies distribute central policies and decide for each data class whether to warn, redact, or block.

Audit without prompt content

For traceability, PromptGuard records categories and actions—not the prompt or the detected value.

CONTROLLED B2B PILOT

A secure real-world pilot, together.

PromptGuard is not yet a fully deployed enterprise DLP system. We are starting with selected companies in a clearly scoped pilot: managed desktop browsers, supported AI websites, and jointly defined policies.

Current protection does not cover private devices, native apps, screenshots, or other transmission channels.

PromptGuard is an independent product and is not affiliated with OpenAI, Google, Anthropic, or Microsoft. All trademarks belong to their respective owners.
