The rise of generative AI platforms like ChatGPT, Google Gemini, and Microsoft Copilot has created a significant new data security risk for enterprises. Employees are increasingly pasting confidential documents, customer data, source code, financial records, and legal agreements into AI chatbots — often without realising the data security and compliance implications.

According to recent security research, over 40% of employees have shared sensitive work data with AI platforms, with many unaware that such data may be used for model training or stored on external servers. For regulated industries in Hong Kong — banking, insurance, legal, and healthcare — this represents a serious PDPO, HKMA, and SFC compliance risk.

The Top AI Platform Data Leak Risks in 2026

ChatGPT / OpenAI

Employees pasting contracts, client data, financial models, and internal strategies into ChatGPT conversations. Business data may be used in OpenAI model training.

Google Gemini

Sensitive documents uploaded to Gemini via Google Drive integration. Customer PII, medical records, and legal documents at risk of exposure.

Microsoft Copilot

Copilot's deep integration with Microsoft 365 means sensitive emails, SharePoint files, and Teams conversations can be inadvertently surfaced or shared.

Other AI Tools

Claude, Perplexity, GitHub Copilot, Notion AI, and countless other AI tools integrated into employee workflows create multiple uncontrolled data exit points.

How NextGuard AI DLP Blocks Data Leaks to AI Platforms

NextGuard Technology has developed purpose-built AI platform protection policies that detect and block sensitive data uploads to generative AI tools in real time, across all channels:

→
Web Gateway DLP
Inspects all browser-based uploads and form submissions to AI platforms. Detects sensitive content (PII, financial data, confidential documents) before it reaches ChatGPT or Gemini servers.
→
Endpoint DLP Agent
Monitors copy-paste activity, clipboard content, and application-level uploads from Windows, macOS, and Linux endpoints. Blocks sensitive data before it leaves the device.
→
AI Content Classification
Uses large language models (LLMs) to understand the semantic context of content — not just keyword matching. Identifies sensitive data even when paraphrased, translated, or encoded.
→
Pre-built AI Platform Policies
Ready-to-deploy policy templates for ChatGPT, Gemini, Copilot, Claude, and 50+ other AI platforms. Deploy in minutes with zero custom configuration required.
→
User Education Alerts
Instead of silently blocking, NextGuard can display real-time warning messages to educate employees about data security policies — reducing repeat violations.

5 Steps to Secure Your Enterprise Against AI Platform Data Leaks

Inventory all AI tools in use

Conduct a shadow AI audit to identify every AI platform employees are using, both sanctioned and unsanctioned.

Classify your sensitive data

Use AI-powered data classification to identify what constitutes sensitive data in your organisation — PII, financial data, IP, legal documents, health records.

Deploy DLP across all channels

Install endpoint agents, configure web gateway DLP, and enable email inspection to cover every potential data exit point.

Set graduated response policies

Start with monitor-only mode to understand usage patterns, then move to warn, and finally block for the highest-risk data types and AI platforms.

Train employees on AI security

Combine technical controls with security awareness training. Employees who understand the risks are less likely to take shortcuts with sensitive data.
