Abstract: The objective of this research is to quantitatively evaluate the performance and security functionalities of the main firewalls based on free software currently available. Metrics such as bandwidth, jitter and packet loss rate were used to measure the network performance of the firewalls using the iPerf3 tool. The htop tool was used to check the CPU and RAM consumption of the solutions. It was identified that Endian, Zentyal, pfSense, OPNsense, VyOS, IPFire and ClearOS provide a set of functionalities that contribute to increase the security in data networks. The results obtained showed that ClearOS has the best overall CPU and RAM consumption rates, which demonstrated its high efficiency in securing data networks with savings and optimal use of hardware resources. The identified findings facilitate decision making for the deployment of cyber-security tools in digital networks of organizations with scarce computational resources.
