Data Leakage to AI Providers

Managing the risk of sensitive data reaching third-party AI services through employees and applications.

Editorial team 1 min read

Using AI services means sending data to them. Organisations need to control what goes where.

How Data Flows Out

  • Employees pasting documents, code or customer data into AI chat tools.
  • Applications sending prompts containing personal or confidential data to model APIs.
  • Browser extensions and plugins with broad access.
  • Integrations connecting AI tools to email, files and CRM systems.

Assess Providers

  • Is data used for training? Can that be switched off?
  • How long is data retained, and where is it stored?
  • What security certifications and contractual commitments exist?
  • Are there enterprise terms with stronger protections?

Controls

  • Approved tools: provide sanctioned AI tools with suitable terms, so staff don't turn to unapproved ones.
  • Policies: define what data may be used with which tools.
  • Technical controls: data loss prevention, blocking unapproved services, redacting sensitive data before sending.
  • Training: explain the risks with realistic examples.

Self-Hosting

For the most sensitive data, consider models hosted in your own environment, weighing capability, cost and operational effort.

Review

Audit AI tool usage periodically, including shadow AI adoption.
