This guide could help keep your whole organization safe.

You wouldn’t allow unmanaged devices on your network, so why allow unmanaged AI into your meetings?

Shadow IT is becoming one of the biggest blind spots in cybersecurity.

Employees are adopting AI notetakers without oversight, creating ungoverned data trails that can include confidential conversations and sensitive IP.

Don't wait until it's too late.

This Shadow IT prevention guide from Fellow.ai gives Security and IT leaders a playbook to prevent shadow AI, reduce data exposure, and enforce safe AI adoption, without slowing down innovation.

It includes a checklist, policy templates, and internal comms examples you can use today.
