RouterOS and pfSense are software solutions designed to allow computers to function as network perimeter firewalls and routers for local area and wide area networks. RouterOS is developed by MikroTik, a company that also develops router hardware. Although pfSense and MikroTik's RouterOS are designed with similar applications in mind, they differ somewhat, primarily in terms of the features included, compatibility and licensing.
