Shadow AI refers to AI tools and applications that employees use without official IT approval or oversight, including personal ChatGPT accounts, browser-based AI assistants, or AI coding tools installed on work devices. It's a security risk because sensitive business data, customer information, and intellectual property can be entered into these tools and stored on third-party servers outside your control. Shadow AI also creates compliance gaps, since data processed by unsanctioned tools may violate GDPR, HIPAA, or industry-specific regulations. Aona detects Shadow AI usage across your organisation so you can assess, govern, or block it as appropriate.
