What is Firewall?
What does 'Firewall' mean?
A Firewall in Endpoint Detection and Response (EDR) software refers to a security feature designed to monitor, control, and filter network traffic to and from endpoint devices based on predefined security rules. It acts as a barrier between trusted internal systems and potentially harmful external networks, blocking unauthorized access and preventing the spread of threats. The firewall feature helps detect and stop malicious connections, restricts access to specific applications or ports, and ensures compliance with network security policies. By providing granular control over network activity at the endpoint level, it enhances threat prevention, reduces attack surfaces, and strengthens overall cybersecurity defenses.
