Using a hardware firewall provides significant benefits, one of which is its capability to monitor all external network traffic. This feature is crucial for enhancing network security, as the hardware firewall analyzes incoming and outgoing data packets, helping to detect and thwart potential threats before they can reach the internal network. By effectively filtering traffic based on predefined security rules, a hardware firewall can prevent unauthorized access and attacks such as intrusions, malware, and denial-of-service attacks.

Monitoring all network traffic allows for better visibility and control over what enters and exits the network, ensuring that only legitimate traffic is permitted. This proactive approach to security is vital for organizations that must protect sensitive data and maintain the integrity of their systems in an increasingly complex digital landscape.

Other options may suggest aspects related to maintenance or updates, but they do not capture the core function of a hardware firewall, which is primarily focused on traffic analysis and security monitoring.
