Living with Falcon Daily
Performance Impact
Falcon is designed for minimal performance impact:
- Low CPU usage during normal operation
- Brief spikes during scans or updates
- Minimal memory footprint
- Efficient cloud communication
If you notice significant slowdowns, contact IT—this could indicate a configuration issue or threat investigation.
What Triggers Alerts
Normal activities that may trigger Falcon review:
- Running scripts or command-line tools
- Installing new software
- Using development tools
- Accessing certain network resources
- Connecting USB devices
Don’t worry about false positives—your security team reviews alerts and whitelists legitimate activity.
USB Device Control
Falcon may enforce USB policies:
- Block unauthorized storage devices
- Allow only encrypted drives
- Permit approved keyboards and mice

When Falcon Blocks Something
If Falcon prevents an action you need to take:
- Note the exact error message or behavior
- Document what you were trying to do
- Contact your IT help desk
- Explain the business need
- Wait for security review and potential exception
Never attempt to disable or circumvent Falcon—this violates security policy and may trigger incident response.
Falcon and Privacy
What Falcon monitors on government systems:
- Process names and behaviors
- Network connections
- File operations
