A device shows as "offline" or "unprotected"

The symptom

In your SentinelOne overview, a device shows as "offline" or "unprotected" although it should be active.

Possible causes

• The device is simply switched off or without Internet: this is normal, it resyncs once back online.
• The agent was stopped, paused, or uninstalled (on purpose or not).
• A conflict with another antivirus left installed.

What to do (step by step)

1. Check the device is on and connected, then wait a few minutes: the status updates by itself.
2. On the device, check the SentinelOne agent is running (icon / services).
3. Uninstall any other antivirus still present (only one at a time).
4. If the agent is gone, reinstall it (see "Install the SentinelOne agent on a device").

If the problem persists

Open a ticket stating the device name and since when it shows offline.
