What is CrowdStrike Falcon?

CrowdStrike Falcon is a cloud-based security tool and it is the default Berkeley Lab antivirus software for Windows and Mac.

CrowdStrike Falcon is different from legacy antivirus because the CrowdStrike Falcon platform:

  • Delivers its features through a single, lightweight agent that is managed from the cloud, protecting your system
  • Does not scan files but uses real-time process control to monitor executable files, scripts, and network activity allowing it to stop threats more effectively

Why did Berkeley Lab pick CrowdStrike Falcon?

CrowdStrike Falcon provides advanced protection against viruses, malware, ransomware, cyber-attacks, and other malicious activity for Berkeley Lab systems. CrowdStrike Falcon greatly protects your computer from attack.

CrowdStrike Falcon will replace Sophos Antivirus, which will be discontinued on July 20, 2023.

I received a notification saying I do not have virus protection during the CrowdStrike Falcon installation, should I worry?

No, because Crowdstrike Falcon is a cloud-based product while Sophos is locally installed, there may be a brief lag time the Windows system thinks there is no antivirus installed, prompting the Windows Security Center notification. Once CrowdStrike Falcon is fully installed and configured, those will go away.

How do I know if Crowdsrike finds something?

A notification will pop up on your system just like any other notification from other software. Windows notifications will be on the bottom right, and Macs will be on the upper right by default.

Will CrowdStrike Falcon slow down my computer?

Unlike traditional antivirus, the software does not scan your hard drive, so there is less impact just by the architecture differences. There is no perceptible performance impact on your computer. The sensor’s design makes it incredibly lightweight (consuming 1% or less of CPU) and unobtrusive: there’s no UI, fewer reboots, and all updates are performed silently and automatically when possible.
