ChatGPT Data Loss Prevention for Teams
Traditional data loss prevention tools monitor files, email and storage. They were not built for the prompt box. When employees paste client details, financial records or internal project data into ChatGPT, most DLP systems see nothing.
Ventrin is a Chrome extension that scans and sanitises employee prompts locally in the browser before they are sent to ChatGPT, Claude, Gemini or Copilot. When sensitive content is detected, Ventrin warns the employee, rewrites the prompt automatically, or blocks the send — depending on your team's policy. Sensitive data never leaves the device unintentionally. Admins see every risk event in a central dashboard.
Why AI prompts create a new data leak path
Most DLP systems inspect file transfers, email attachments and USB devices. They were designed before AI tools existed. Today an employee can paste a full client contract into ChatGPT in seconds — and most security platforms will not raise an alert.
The prompt box has become an unmonitored channel. Employees are not trying to cause harm. They are trying to complete work faster. The result is the same: confidential content leaving the organisation through a tool no one can see into.
Contract terms, client names, matter references and correspondence copied directly into a prompt.
Employee records, candidate profiles, customer PII and date of birth details used as context.
API keys, tokens, passwords and internal access details included in debugging prompts.
Revenue figures, forecasts, margin data and account details shared to generate summaries.
Proprietary code, configuration files and system architecture pasted for review or debugging.
How Ventrin provides prompt-level DLP
Ventrin is a Chrome extension that runs entirely on the employee's device. Before a prompt is sent to ChatGPT, Claude, Gemini or Copilot, Ventrin scans it for sensitive content.
When a risk is detected, Ventrin can warn the employee, rewrite the prompt with sensitive details removed, or block the send entirely — depending on the policy your team has configured.
No prompt content is processed on Ventrin's servers. Detection happens locally in the browser, which means sensitive details never leave the device unintentionally.
Key Ventrin features for this use case
On-device detection model runs before every send. No data egress for the scan itself.
Identifies client names, contact details, matter references, financial figures and internal identifiers.
Rewrites prompts to preserve intent while removing or generalising specific sensitive details.
API keys, tokens and passwords are blocked, not rewritten. They should not reach AI tools.
Every flagged event is logged. Admins can review risk type, action taken, tool used and timing.
Works with ChatGPT, Claude, Gemini, Copilot and other browser-based AI tools.

Built for teams that cannot afford a data incident
Local-first detection
The scanning model runs in your browser, not on our servers. Sensitive content never leaves the device for analysis.
No data egress
Ventrin does not receive, store or process your team's prompt content. Only risk event metadata is logged.
Configurable policy controls
Warn, sanitise or block based on content type and team role. Full control over how the extension behaves.
Admin event logs
Every flagged event is recorded with risk type, action and timestamp. Provides the audit trail your compliance process needs.
Protect your team's AI use from the browser
Ventrin deploys as a Chrome extension. No proxy, no network change, no IT project. Most teams are protected on the same day.
Frequently asked questions
No. Ventrin fills a gap most DLP systems leave open: the AI prompt box. Traditional DLP monitors file transfers, email and storage. It was not designed to inspect what employees type into ChatGPT. Ventrin works alongside your existing security stack as a focused layer for AI prompt protection.
No. Ventrin's detection runs entirely on the employee's device. When a prompt is scanned and sanitised, the original content stays local. Only the rewritten, safe version is sent to the AI tool. Ventrin's servers do not receive prompt content.
Yes. Ventrin does not block AI tools. It makes them safer. Ventrin only intervenes when a risky pattern is detected. Most everyday prompts will pass through without any action. Employees continue working normally.
Ventrin detects PII including names, email addresses, phone numbers, dates of birth and national identifiers. It also detects credentials such as API keys and tokens, financial figures, internal project names and matter references. Detection categories are configurable by policy.
Ventrin deploys as a Chrome extension. An admin sets policies in the dashboard, then invites team members or distributes via Chrome management. Most teams are protected within a day, with no infrastructure changes required.
Yes. Every flagged prompt generates an event in the admin dashboard showing risk type, action taken, AI tool involved and timestamp. The original sensitive content is not stored — only the risk classification metadata.
