What is shadow IT?
Shadow IT happens when employees use apps, cloud services or devices without IT approval. Examples include file sharing tools, AI apps, browser extensions and personal cloud storage.
Why it is risky
Unapproved apps may store company data, lack MFA, have weak sharing controls, create compliance issues or continue to hold data after employees leave.
How to find shadow IT
Review expense reports, SSO logs, DNS logs, browser extensions, endpoint software inventory, firewall logs and cloud access security tools.
Manage instead of only blocking
Some shadow IT exists because users need better tools. Understand the business need, approve safe alternatives and create a simple app request process.
