About Us

opnsense.download is a fan site about OPNsense, the open-source firewall and routing platform built on HardenedBSD. We are not the official developers of the software and we have no connection with Deciso B.V. — we are simply a group of enthusiasts who deploy OPNsense every day and enjoy writing about it.

Who We Are

We are a small, independent team of network engineers, security consultants and technical writers spread across two continents. Between us we run everything from a quiet home lab with a single fanless mini PC to multi-site corporate networks where OPNsense protects hundreds of users behind redundant firewalls. The opnsense iso has been our default perimeter for years, and this site is our way of giving something back to the community that helped us learn it.

The project started the way most fan projects do: one of us kept answering the same questions in forums and chat channels — how to size hardware for multi-gigabit links, when to choose WireGuard over IPsec, how to plan a VLAN layout that scales. Instead of repeating ourselves, we decided to collect that knowledge in one place. Today the site carries a growing guide section, the story of the software and honest, experience-based notes about running it in real environments.

What We Stand For

• Independence. We receive no money from Deciso or any other vendor and we buy our own coffee. Everything we publish reflects our own opinions and hands-on testing.
• Clarity. We write guides the way we wish someone had written them for us: plain language, real examples, no marketing fluff.
• Respect for the original. We always point readers to official sources for the opnsense download and support, and we never host modified firmware or misleading files.
• Openness. Found a mistake or disagree with our advice? Tell us. Corrections make the whole site better for everyone.

How We Work

Every article on this site is tested before it is published. When we describe a firewall rule, a VPN tunnel or a high availability setup, we run it on our own equipment first — usually more than once, because networks are unforgiving. We revisit older pages regularly, since OPNsense develops quickly and details change between releases.
