Confidential Company Data
This may seem obvious, but its importance cannot be overstated. Never paste internal documents, strategic plans, financial reports, sales data, or upcoming product details into a public AI tool. Many AI services use your input data to train their models,
meaning your company's secrets could inadvertently be absorbed and later appear in a response to another user. Even if the AI provider has strong privacy policies, a data breach could expose everything you've entered. Some companies, including major financial institutions, have banned or restricted the use of public AI chatbots for this very reason. Always use company-approved AI services that have been vetted for enterprise-level security.
Client and Customer Information
Pasting any client or customer data into an AI chatbot is a major privacy violation and a significant legal risk. This includes names, contact details, purchase histories, support tickets, or any personally identifiable information (PII). Doing so could violate data protection regulations like GDPR and create serious liability for your employer. Remember, an employee entering a customer's information into an external AI tool for convenience makes the organization liable for any resulting data exposure. These systems are not bound by the same confidentiality rules as employees, and leaking customer data can destroy trust and lead to severe penalties.
Personal Identifiable Information (PII)
This rule applies to your own information as well as that of your colleagues. Avoid sharing any personal details, such as home addresses, phone numbers, government ID numbers, or medical information. While it might be tempting to ask a chatbot to format your resume or review a document containing these details, the risk of that data being stored indefinitely or exposed in a breach is too high. AI models can collect and merge various pieces of information, creating detailed profiles that could be misused if they fall into the wrong hands. The golden rule is simple: if you wouldn't post it on a public forum, don't paste it into a chatbot.
Proprietary Code and Internal Passwords
Developers often turn to AI to help write, debug, or optimize code. However, pasting proprietary software code into a public chatbot is like handing your company's intellectual property to a third party. That code could become part of the model's training data, potentially exposing trade secrets. It is equally critical to never paste any login credentials, API keys, or passwords into a chatbot, even if you're troubleshooting an error message. This sensitive data could be stored in conversation logs, reviewed by human moderators, or leaked in a security incident, creating a massive vulnerability for you and your organization.
Internal Memos and Sensitive HR Documents
Never use an AI chatbot to summarize meeting notes from a confidential discussion, draft a sensitive internal memo, or review performance-related HR documents. These materials often contain opinions, criticisms, or strategic information that is not meant for public consumption. Exposing this information could create legal and ethical problems for the company, especially if it involves employee assessments or disciplinary actions. AI tools should not be used for making or influencing employment decisions like hiring or promotions without strict oversight, as they can reflect and amplify existing biases.
Vague or Unsanitized Prompts
Beyond specific data types, it's also about how you ask questions. Avoid prompts that include specific names, project codenames, or internal jargon that could indirectly reveal sensitive information. Instead of asking, "Summarize my notes from the Project Titan meeting with Acme Corp," try a generalized prompt like, "Summarize these notes about a client partnership meeting." By sanitizing your prompts and removing identifying details, you can leverage the power of AI for tasks like summarization and drafting without exposing confidential context. This practice minimizes risk while still allowing you to benefit from the tool's capabilities.
