How to catch unauthorized AI tools employees are using on the network

IT teams struggle to detect shadow AI usage because standard application controls only track approved software, leaving blind spots for unmanaged tools. Without clear visibility into what employees are running on their endpoints, organizations cannot monitor or control unauthorized AI adoption across the enterprise network.
