Pfsense is open-source firewall developed by Netgate Inc.
It includes the same features as most expensive commercial firewall solutions. In some cases, pfSense includes additional features that are not available in commercial closed source solutions.
The pfSense project is a free network firewall distribution, based on the FreeBSD operating system with a custom kernel and including third party free software packages for additional functionality.
pfSense software includes a web interface for the configuration of all included components. It could be configured through command-line, but you no need to use it.
Unlike most common commercial firewalls offerings, the pfSense project is just the software portion of the firewall. This means you get to tailor the hardware you choose to meet your environment’s specific needs. Also, you have options to buy directly from Netgate or one of many Netgate Partners, Security Gateway Appliance.
Netgateās pfSense software is available in the cloud providers (Amazon, Azure, Hetzner, …) to protect your cloud applications.
