Why AI Security Matters

AI tools are powerful — and that power comes with responsibility. When you interact with an AI system, you're often sharing information with a third-party service. Understanding where that data goes, how it's stored, and who can access it is important for anyone using AI at work or in personal contexts.

Key Risks to Understand

Data Exposure

Information you type into a public AI tool may be used to train future versions of the model, stored on third-party servers, or accessible to the company's employees. This is fine for general questions — it matters a lot when the information is sensitive.

Prompt Injection

A type of attack where malicious content in a document or webpage attempts to manipulate an AI's behavior — for example, instructions hidden in a document that tell an AI assistant to exfiltrate data or produce harmful outputs.

Overconfident Outputs

AI systems can produce incorrect information confidently. Acting on bad AI advice — in a medical, legal, or financial context — without verifying it is a genuine risk.

Phishing and Social Engineering

AI is being used to generate highly convincing phishing emails, fake voices, and deepfake videos. Being skeptical of unexpected communications — even ones that seem to come from known contacts — is increasingly important.

What Not to Share with AI Tools

  • Passwords or authentication credentials
  • Financial account numbers or payment data
  • Personal health information
  • Confidential business data, M&A information, or internal strategy
  • Other people's personal information without their knowledge

A simple rule: if you wouldn't be comfortable with that information appearing in a data breach, don't share it with a public AI tool.

Safe AI Practices

  • Use enterprise versions of AI tools where possible — they typically offer stronger data protections
  • Check whether your AI tool allows you to opt out of training data collection
  • Anonymize or generalize sensitive information before inputting it
  • Verify important outputs before acting on them

For Organizations

Companies introducing AI tools should establish:

  • A clear policy on which AI tools are approved for use
  • Data classification guidelines — what information can and can't be shared with AI
  • Basic employee training on AI risk awareness
  • A process for staying current as the tool landscape evolves
