What is the purpose of host-based firewalls in Falcon?

Host-based firewalls in the CrowdStrike Falcon platform are designed primarily to filter network traffic and prevent unauthorized access. This function is crucial as it establishes a security barrier directly on the endpoint, which allows organizations to control which applications and services can send or receive data across the network.

By using rules and policies, host-based firewalls can allow or block traffic based on specified conditions, such as IP addresses, protocols, and ports. This capability helps to protect endpoints from potential threats and malware that may attempt to exploit network vulnerabilities.

Furthermore, the integration of host-based firewalls within a broader endpoint protection strategy enables organizations to maintain a robust security posture by extending their defensive perimeter from the network to individual devices. By focusing on filtering and access control, host-based firewalls complement other security measures, adding depth to the overall cybersecurity framework.
