AI Adoption Is Outpacing Security — And Your Audit Trail

Your team is already using ChatGPT, Claude, Gemini, and Copilot daily. Sensitive data is being pasted into prompts — often unintentionally. Most organizations have zero visibility into what's being sent, and zero documentation if they're ever asked.

Sound familiar?

  • ?
    "We have no idea what's being pasted into ChatGPT"
  • ?
    "Our DLP doesn't cover browser-based AI tools"
  • ?
    "We can't prove what was or wasn't sent to AI"
  • ?
    "Secure browsers are too expensive and disruptive"
  • ?
    "We need visibility without blocking productivity"

PromptFence solves all of this — in minutes, not months.

Complete Visibility. Configurable Control.

PromptFence intercepts AI prompts at the browser level — before data leaves. You decide what to block, what to warn on, and what to log.

Real-Time Prompt Interception

PromptFence captures prompt content the moment a user hits "send" — before it reaches the AI provider. Sensitive patterns are detected and blocked instantly. No API integration required. Works at the browser layer across all supported platforms.

Block, Warn, or Log — Your Rules

Configure policies per pattern, per platform, or per user group. Hard-block the riskiest content. Warn users on borderline submissions. Silently log everything else.

New

Smart Redaction

Automatically detect and redact PII before it reaches AI — emails, SSNs, credit cards, API keys. Users review what's redacted, AI gets sanitized prompts, and responses restore original values automatically. Use AI without exposing sensitive data.

Full Audit Logging — The Flight Recorder for AI

When compliance matters, capture everything: full prompt text, AI responses, timestamps, and user identity. Exportable logs for audits, client inquiries, and regulatory review. When privacy is the priority, switch to metadata-only mode — same protection, no content stored.

One Dashboard. Every AI Interaction.

See who's using which AI tools, how often, and what's triggering your policies. Usage trends, block rates, top users, and exportable reports — all from a single pane. Slack and Teams alerts when high-risk events occur.

Deploys in Minutes. Protects Immediately.

1. Install

Push the PromptFence extension via Group Policy, Intune, Jamf, or a simple install link. Zero user action required for managed devices.

2. Configure

Set your policies in the admin dashboard. Define what to block, warn, or log. Choose full prompt logging or metadata-only mode.

3. Protect

PromptFence monitors every AI interaction in real-time, enforcing your rules before any data leaves the browser.

When sensitive content is detected, PromptFence responds instantly — before submission.
