What leaks to Gemini - and why
The four exfiltration patterns we see most often when teams adopt Gemini.
Workspace context bleeds into prompts
Users paste Google Doc content, Sheet rows, and Calendar invite details into Gemini for summarisation. The full content travels upstream - including embedded customer data and internal financials.
Massive context windows invite massive pastes
Gemini's 1M+ context window means people paste entire support inboxes, audit reports, and design docs in one shot. Per-prompt exposure is much higher than ChatGPT's typical pattern.
AI Studio is a developer playground with prod data
Engineers test prompts in AI Studio using real production data because it's faster than building a fixture. Whatever they paste lands on Google's logs.
Browser-native, easy to use from any account
Gemini is one tab away in any Chrome window. Shadow-AI usage is widespread; a network-only DLP that doesn't cover the personal-account case sees nothing.
What Gemini actually sees, with NexusNest in front
The user types whatever they want. NexusNest redacts the sensitive spans in-flight, so the prompt that reaches Google 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 Gemini traffic to flow through it.
Open your AI tool as normal
Use Gemini 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. Gemini usage becomes legible.
Gemini DLP - common questions
Does it cover the Gemini integration in Gmail and Docs?
Yes - Workspace AI features call the same Gemini backend. The agent intercepts the underlying `:generateContent` endpoint, which is what the "Help me write" sidebar uses.
Does it work with Google AI Studio?
Yes. AI Studio traffic goes to the standard Gemini API and is intercepted with the same `gemini-generate` schema (`contents[*].parts[*].text`).
Are my Workspace files at risk if I don't paste them?
If you're only using Workspace AI features that summarise files you already have in Workspace, that content stays in Google's cloud either way. NexusNest's job is to redact the prompt text users type or paste into the Gemini surface - that's the loss vector.
Will this affect Gemini's grounding / search results?
No. Grounding queries are derived from the redacted prompt by Gemini itself. The placeholders flow through grounding unchanged, and you get answers based on the redacted but semantically-intact prompt.
Does Google Workspace's existing DLP cover Gemini?
Workspace DLP rules scan documents and email; they do not inspect prompts sent to Gemini. NexusNest fills that specific gap.
