What leaks to ChatGPT - and why
The four exfiltration patterns we see most often when teams adopt ChatGPT.
Customer PII pasted into prompts
The single most common ChatGPT leak: an employee pastes a customer email, support transcript, or CRM export and asks for a summary. The full row hits OpenAI's logs.
API keys, AWS credentials, and `.env` snippets
Debugging help requests routinely include real production credentials. AKIA…, sk-…, and Bearer tokens regularly show up in ChatGPT conversation history.
Proprietary source code and internal documents
Pasting an internal RFC or a chunk of a private repo for a refactor sends that IP to a third party. OpenAI's enterprise terms help on the policy side; they don't undo a paste.
Anonymous / temporary conversations bypass governance
ChatGPT supports unauthenticated and temporary chats that don't tie to a corporate identity. Many network-only DLP tools only see signed-in traffic and miss these entirely. NexusNest covers both.
What ChatGPT actually sees, with NexusNest in front
The user types whatever they want. NexusNest redacts the sensitive spans in-flight, so the prompt that reaches OpenAI has placeholders in place of the secrets.

Set up in 2 minutes
Install the agent
Download the .pkg / .exe and double-click. The agent installs a local trusted CA and the system proxy - no IT ticket required for ChatGPT traffic to flow through it.
Open your AI tool as normal
Use ChatGPT exactly the way you do today - browser, desktop app, or API. The agent intercepts the outgoing request, runs the redaction pipeline, and forwards a redacted version.
Watch the dashboard
Every prompt shows up in the admin dashboard with what was redacted, by which employee, on which machine. ChatGPT usage becomes legible.
ChatGPT DLP - common questions
Does it work with the ChatGPT desktop app?
Yes. The agent installs a system proxy that intercepts traffic from the ChatGPT macOS and Windows desktop apps, not just the browser. Same for ChatGPT Voice and the iOS/Android API calls when routed through the device.
What about ChatGPT temporary chats and the 'anonymous' flow?
Both are covered - signed-in conversations and the temporary / unauthenticated flow. Naive DLP tools only inspect signed-in traffic and miss the rest; NexusNest sees every prompt either way.
Does this break Custom GPTs or file uploads?
No. Only the user-authored prompt text is scanned. Files attached to a conversation pass through untouched (they're a separate upload endpoint we explicitly do not modify).
Will OpenAI flag the redacted prompts as suspicious?
No. The redacted output is plain text with placeholders like [REDACTED_PERSONAL_INFO_1]. ChatGPT treats them as opaque tokens, answers the underlying question, and you get a normal response.
Does ChatGPT Enterprise / Team already cover this?
ChatGPT Team and Enterprise add training-data opt-outs and SAML SSO. They do not redact what users type - your prompts still leave the device verbatim. NexusNest sits in front of that and removes sensitive content before it reaches OpenAI.
