Browser Guard

Stop sensitive data before you press send.

A browser extension that follows your Secpresio rules and enforces them on supported AI websites. It warns, masks or blocks in real time, and sends privacy-conscious security event metadata to your workspace.

How Browser Guard protects

Detect. Enforce. Report.

Protection runs in the moment that matters: when someone is about to submit text or a file to an AI website.

Detect

Rules identify what should not leave the company.

  • Credentials and API keys
  • Validated identifiers and payment data
  • Custom company terms and patterns

Enforce

The rule decides the outcome, per policy.

  • Allow, warn, mask or block
  • Clear, in-context explanations
  • Optional user override settings

Report

Every action becomes a reviewable event.

  • Events synced to the SaaS workspace
  • Email alerts and daily digest for superusers
  • Category and action recorded per event
Outcomes

The right response for every rule.

Allow

Safe content goes through untouched. Your team keeps its speed and the event stays visible to admins.

Warn

The user sees what was detected and why, and decides whether to edit or continue. The warning is recorded.

Mask

Sensitive values are replaced before the prompt leaves the browser, so the request still works without the secret.

Block

The prompt is stopped before it is sent. The user gets a clear explanation and the event is reported.

Coverage

The AI websites your team already uses.

Browser Guard works through adapters for each supported service. Active enforcement is available for all of them in the browser.

Coverage boundary. Browser Guard protects supported AI websites and submission paths. It does not monitor every browser, native app or private API call. For Windows desktop apps, use Desktop Guard.
