Data Leaking to ChatGPT? Meet Gemini

Gemini Enterprise is a secure generative AI platform that runs within a private Virtual Private Cloud with zero data retention and contractually guaranteed privacy. For enterprises facing existential intellectual property leakage risks from shadow IT, this solution provides a secure alternative that turns compliance vulnerabilities into an auditable advantage.

TL;DR In a recent audit, 40% of employees at a bank were using Shadow IT to summarize confidential PDFs in free ChatGPT. Banning doesn't work — giving a better tool does. Gemini Enterprise runs in a private VPC, zero retention, BAA contract and grounding on real data. What was an existential risk becomes an auditable advantage.

In a recent audit, we discovered that 40% of a bank's employees were using AI tools "outside" (Shadow IT) to summarize confidential PDFs. The risk of IP (Intellectual Property) leakage is existential.

⚠️ Real shadow IT scenario Your employee copies an M&A strategy and pastes it into free ChatGPT. Congratulations — that information may now be part of the global model's training. Banning by email doesn't solve it; giving a better tool and monitoring egress via DLP/CASB does.

The solution is not to ban (no one obeys). The solution is to provide a better, secure tool — and block the exit to the insecure ones.


The VPC wall: Gemini Enterprise vs ChatGPT Team

Gemini Enterprise runs inside your VPC (Virtual Private Cloud). The difference is dramatic for Compliance:

Feature ChatGPT (Public/Team) Gemini Enterprise (Vertex AI)
Data privacy Configurable "opt-out" Private-by-Design (zero retention)
Network Public internet Private VPC (Google backbone)
Legal contract Standard terms of service DPA + BAA (when applicable)
Data residency Globalized sa-east1 (São Paulo)
Use in public model training Depends on plan Contractually never
ANPD / BCB audit Limited Full logs + VPC-SC

Grounding: the corporate truth

Models hallucinate. Fact. For enterprise use, we connect Gemini to your data sources (ERP, CRM, BigQuery, SharePoint) via Grounding:

Query: "What was March revenue?" > Searching BigQuery (Sales_Table)... > Found: R$ 4.2M > Response: "Revenue was R$ 4.2M [Source: ERP, table Sales_Table, row 2026-03]"

If you ask "What was March revenue?", it doesn't make up a number. It queries BigQuery, reads the real data and responds with a source citation. No source, no answer. This transforms AI from a "buzzword generator" into an auditable oracle.

Banning AI is naïve — your employees are already using it, and you just don't know. The mature path is: secure corporate tool + DLP/CASB blocking the insecure ones + training + audit. That's real governance, not policy theater.
