What is CrowdStrike Falcon?
CrowdStrike Falcon is a cloud-native endpoint protection platform that utilizes artificial intelligence to prevent, detect, and respond to cyber threats in real time. It is designed for use by security operations center (SOC) analysts and penetration testers to ensure comprehensive endpoint security.
Installation
Installing CrowdStrike Falcon requires administrative privileges on the endpoint and a valid subscription. The installation process typically involves:
- Receiving an invitation to the Falcon console from your organization.
- Downloading the Falcon sensor package appropriate for your OS.
- Running the installer with administrative rights.
- Entering your organization’s unique customer ID.
- Verifying agent installation via the Falcon console.
