Triage CrowdStrike Falcon Detections with a PowerShell Workflow
Inventory Falcon-protected hosts, pull recent detections, contain compromised endpoints, and surface sensor gaps from one PowerShell workflow.
CrowdStrike Falcon is built to be queried, but a lot of SOCs still spend their morning clicking through the console. The Falcon API and the PSFalcon module make every part of that morning routine scriptable.
PSForge gives you the Falcon tasks ready to assemble into a workflow that handles inventory, detection triage, and containment with one repeatable run.
What a Falcon morning workflow should produce
- Every host with a sensor, its OS, last seen, and group membership
- Hosts with a sensor that has not checked in for 7+ days
- All open detections from the last 24 hours with severity and status
- Hosts with multiple recent high-severity detections (likely incidents)
- Sensor version distribution to identify hosts behind the recommended build
Why this is a workflow problem
Each piece is a few lines of PowerShell. The value is in running them in order, every morning, and producing one summary that the SOC can act on before standup.
When something does need response, the same workflow can quarantine a host, kick off a real-time response session, or pull recent process activity for further analysis.
Example Falcon triage workflow
- Authenticate to the Falcon API with a stored OAuth client
- List every host with a sensor and its last contact time
- Flag hosts that have not contacted the cloud in 7+ days
- Pull all detections from the last 24 hours with severity and assigned analyst
- Surface hosts with multiple recent high-severity detections
- Optionally network-contain a host with a confirmed compromise
- Capture sensor version distribution and flag hosts behind the recommended build
- Send the consolidated triage report to the SOC distribution list
Final thoughts
Falcon is one of the most scriptable EDRs on the market, and SOCs that lean into that automation move incidents through triage faster.
PSForge makes it easy to build a single PowerShell workflow that turns the Falcon API into a morning routine, and a containment routine when it counts.
