OPNsense firewalls
Maximum security for your network
OPNsense is an easy-to-use open source firewall and routing platform. Based on FreeBSD, OPNsense combines the rich functionality that is otherwise known only from commercial firewalls, with the benefits of open and verifiable sources. Secure your network with our server systems optimized for OPNsense – all without any licensing fees!
Secure – from the home office to the data center
With its rich feature set, OPNsense is capable of securing small networks, such as home offices, doctors' offices or tax offices, in addition to medium and large environments with up to several hundred users. The functions range from the well-known filtering options of a stateful firewall and virtual private networks (VPNs) for the integration of external users or sites to enterprise features such as captive portals for restricted WLANs, highly available firewall clusters or multi-WAN uplinks. Numerous plugins also allow the functionality of the firewall to be modularly expanded.
Easy to install, highly secure
OPNsense can be installed quickly and easily in just a few steps. Configuration is performed via the intuitive web interface of the open source firewall. For example, firewall rules can be created with just a few mouse clicks. All other functions, such as the configuration of OpenVPN or ipsec VPNs, are set up directly in the web interface. This means there's no need to learn any special command line commands. Security updates are also uploaded directly via the web interface – keeping the firewall up-to-date.
As an OPNsense partner, we actively support the continuous development of the open source firewall. Major updates, and therefore new features, are released in January and July as part of the six-month release cycle.
