Perplexity

1. 01Perplexity trains on data unless a business tier or opt-out is used. Verify which tier these users are on.
2. 02Perplexity runs as a browser extension on 1 device and can read every page those users open, including webmail and internal apps. Manage it with the browser's ExtensionInstallBlocklist or allowlist policy.
3. 03Perplexity was seen only on endpoints, not in Entra or network discovery, so it may be used offline or from unmanaged networks. Check the device list for VPN gaps.
