Imagine them as the gatekeepers of your digital world, and understanding the differences is key to setting up your ultimate security.

Diving into the Origins: A Quick Look at the History

Let’s rewind a bit and look at where these firewalls came from. pfSense, originally conceived as a project by Chris McAnany, has roots that go back to the early 2000s. Its journey started with a vision to provide a powerful, user-friendly firewall solution that anyone could deploy. It quickly gained popularity because of its ease of use and the fact it was free. Over the years, the project has matured, and it’s become a cornerstone of many networks around the world. However, with time, came a change, as it was acquired by a company.

Then, came OPNsense, which emerged as a fork of pfSense. The OPNsense project was initiated by Deciso, a company that develops and sells hardware appliances. OPNsense wanted to give the community a firewall with a modern interface, improved security features, and a faster release cycle. That means OPNsense can release new features and security updates quickly. Both firewalls draw on the power of FreeBSD, but their paths and priorities have diverged, creating two unique and exciting options for anyone looking to build a secure network. So, both firewalls are FreeBSD based but have their own identities.
