OPNsense

OPNsense is a powerful open-source firewall and routing platform built on FreeBSD, designed for both ease of use and robust security. Launched in 2015 as a fork of the pfSense and m0n0wall projects, OPNsense has rapidly evolved to incorporate a comprehensive feature set that rivals even the most expensive commercial firewalls. With a strong emphasis on security and frequent updates, users benefit from state-of-the-art protections against emerging threats.

Key features of OPNsense include a traffic shaper, two-factor authentication, a captive portal, and advanced VPN capabilities, along with intrusion detection and prevention systems. The platform ensures high availability and supports various plugins, making it highly customizable for different use cases.

Developed by a dedicated core team and an extensive community, OPNsense is backed by Deciso B.V., a provider of open-source networking solutions. With a commitment to transparency and user empowerment, OPNsense's mission is to become the most widely adopted open-source security platform available.
