6 Ways to Prevent Leaking Private Data Through Public AI Tools

Public AI tools have become incredibly useful for everyday business tasks. From brainstorming ideas and drafting emails to creating marketing copy and summarizing reports, these tools can save significant time when used appropriately. However, for Small/Medium Businesses in Orange County, CA, the convenience of public AI tools comes with serious risk—especially when customer Personally Identifiable Information (PII) or confidential business data is involved.

Most public AI platforms retain user inputs to train and improve their models. This means a single careless prompt entered into tools like ChatGPT or Gemini could unintentionally expose client data, internal strategies, or proprietary processes. Here at Newport Solutions, we believe that businesses should harness AI’s power without compromising privacy, compliance, or trust. Preventing data leakage before it happens is far easier—and far less costly—than dealing with the fallout afterward.

Financial and Reputational Protection

AI is becoming a critical component of modern business workflows, but safe adoption must come first. The financial and reputational damage caused by an AI-related data leak can be devastating. Regulatory penalties, legal costs, loss of client confidence, and competitive disadvantage often far exceed the cost of implementing preventative safeguards.

A real-world example occurred in 2023 when Samsung employees unintentionally exposed sensitive data by pasting confidential information into ChatGPT. This included semiconductor source code and private meeting transcripts, which were subsequently retained within the AI system. The incident wasn’t the result of a cyberattack—it was simple human error combined with a lack of clear guidelines and technical controls. The outcome forced Samsung to impose a company-wide ban on generative AI tools.

This example highlights a key lesson: without policy and guardrails, even highly skilled teams can create major risks.

6 Prevention Strategies

Below are six practical strategies that help businesses secure AI usage while still benefiting from its productivity advantages.

1. Establish a Clear AI Security Policy

Your strongest defense against accidental data exposure is a well-defined AI usage policy. This policy should clearly identify what qualifies as confidential or sensitive information and explicitly state what must never be entered into public AI tools. Examples include social security numbers, financial records, legal documents, internal roadmaps, and proprietary code.

AI security policies should be introduced during employee onboarding and reinforced through regular training sessions. Clear guidance removes uncertainty, sets expectations, and reduces the chance of risky decision-making.

2. Mandate the Use of Dedicated Business Accounts

Free AI tools often include data usage terms that allow inputs to be retained for model training. To mitigate this risk, businesses should use enterprise-grade AI offerings such as ChatGPT Team or Enterprise, Microsoft Copilot for Microsoft 365, or Google Workspace AI tools.

These business agreements provide contractual assurances that your data will not be used to train public models. While free or basic plans may allow limited opt-out options, business-tier subscriptions create a much stronger legal and technical boundary between your sensitive data and public AI systems.

3. Implement Data Loss Prevention Solutions with AI Prompt Protection

Even with policies in place, mistakes happen. Employees may accidentally paste sensitive information into an AI prompt or upload restricted documents. Data Loss Prevention (DLP) tools act as a critical safety net by stopping data exposure before it occurs.

Solutions such as Microsoft Purview and Cloudflare DLP inspect prompts and uploads in real time at the browser or endpoint level. These tools can automatically block, redact, or alert administrators when sensitive data patterns—such as credit card numbers, client identifiers, or internal project names—are detected.

4. Conduct Continuous Employee Training

Policies alone are not enough. AI-related security training must be ongoing and practical. Interactive workshops help employees learn how to safely use AI tools by anonymizing or de-identifying data before submitting prompts.

By practicing real-world scenarios, employees gain confidence in using AI responsibly rather than avoiding it altogether. This approach turns staff into informed participants in your security strategy instead of accidental risks.

5. Conduct Regular Audits of AI Tool Usage and Logs

Effective security requires visibility. Business-tier AI platforms offer administrative dashboards and activity logs that allow you to monitor usage patterns across your organization. Regular reviews—monthly or quarterly—help identify unusual behavior, misuse, or training gaps.

Audits should focus on improvement, not punishment. They provide valuable insight into where policies may need refinement or where additional education is necessary.

6. Cultivate a Culture of Security Mindfulness

Technology and policies are only as effective as the culture supporting them. Leadership must model responsible AI usage and promote open communication around security concerns. Employees should feel comfortable asking questions or flagging potential issues without fear of reprimand.

When security becomes a shared responsibility, your organization gains a powerful collective defense that no single tool can replace.

Make AI Safety a Core Business Practice

AI adoption is no longer optional—it’s a competitive necessity. That reality makes secure and responsible AI usage essential for long-term success. By implementing these six strategies, businesses can unlock AI-driven efficiency while protecting sensitive data, maintaining compliance, and preserving trust.
