Try this first
- Categorize each alert: 'Informational' (no action), 'Low' (later), 'Medium/High' (today) or 'Critical' (now). The tool already classifies, use that.
- Medium or higher: click into details. Which user, which device, which process? Often you spot familiar work activity or not.
- Unknown process that 'did something with PowerShell': isolate the device (in Defender: 'Isolate device'). Do not power off, keep it online for investigation.
- Gather context on another device: did the user do something unusual? Install a new tool? Ask in person, not by email from the suspect device.
- Do not close alerts without investigation. Better a lingering 'false positive' than something missed.
