AI at Work: How to Use ChatGPT, Claude, and Other AI Tools Without Compromising Your Business's Security

Walk into almost any office today and you'll find employees quietly using ChatGPT to draft emails, Claude to summarize contracts, or Copilot to write code often without IT ever approving it. According to Microsoft's Work Trend Index, 78% of AI users bring their own unauthorized tools into the workplace, and Cisco has tracked a 250% surge in this kind of “shadow AI” use in a single year. Your team isn't trying to cause a security incident. They're trying to get work done faster. But every unmonitored prompt is a potential data exposure, and most businesses have no visibility into it at all.

The risk isn't AI — it's how it's used

AI tools themselves aren't inherently unsafe. The danger comes from what employees paste into them and where that data ends up. Research from Cyberhaven found that 11% of the content employees paste into ChatGPT includes sensitive company information, and the volume of business data shared with AI tools jumped 485% year over year. Salesforce reports that more than a quarter of employees admit to entering confidential company data into public AI tools, and 15% regularly input customer information. Source code, financial figures, client records, and internal strategy documents are all showing up in free, consumer-grade AI accounts that were never designed to handle them accounts your IT team likely can't see or audit.

At the same time, only about a third of companies have a formal policy governing how employees can use AI, and even fewer have the tools in place to detect it happening. That gap between adoption and governance is where most AI-related security incidents start.

Not all AI tools — or AI plans — are created equal

One of the most important things for business owners to understand is that a free, personal ChatGPT or Claude account behaves very differently from a business or enterprise plan.

ChatGPT (OpenAI): OpenAI states that ChatGPT Enterprise, Business, and API accounts are not used to train its models by default, and business plans come with SOC 2 Type 2 certification, AES-256 encryption at rest, TLS in transit, SSO, and admin-controlled data retention. Free personal accounts don't carry the same guarantees.

Claude (Anthropic): Anthropic applies the same “no training by default” standard to Claude for Work, Claude Enterprise, and API usage, and organization admins can disable data submission features entirely. Personal Claude Free and Pro accounts fall under separate consumer terms.

Microsoft Copilot: Because Copilot is built into Microsoft 365, it inherits your existing Entra ID identity management, data loss prevention rules, and conditional access policies making it a strong option for businesses already standardized on Microsoft's ecosystem.

Google Gemini: Similarly, Gemini's strongest security posture shows up inside Google Workspace, where admin controls and existing governance policies extend naturally to AI use.

The pattern is consistent: the safest AI tool for your business is usually a paid, business-tier account that plugs into infrastructure you already control, not whichever free tool an employee downloaded on their own.

What businesses should actually do about it

1. Set a written AI use policy. Define which tools are approved, what data can and can't be entered into them, and who owns the decision to add a new tool.

2. Move employees to business-tier accounts. If your team is going to use ChatGPT, Claude, Copilot, or Gemini anyway, put them on the versions with contractual data protections, admin visibility, and no default training on your data.

3. Gain visibility into shadow AI. Most security teams currently have little to no insight into which AI tools employees are actually using. Network and endpoint monitoring can surface this.

4. Train employees on what not to share. Confidential client data, financial records, credentials, and proprietary code should never go into a consumer AI tool, full stop.

5. Extend your existing security stack. Data loss prevention, SSO, and access controls should cover AI tools the same way they cover email and file storage.

The bottom line

AI tools like ChatGPT and Claude aren't going away, and banning them outright rarely works employees simply find workarounds. The businesses that come out ahead are the ones that get in front of AI adoption with clear policy, the right business-tier accounts, and real visibility into how these tools are being used.
