Ran Untangle for years at a small office. The subscription cost finally got under my skin. Switched to pfSense CE on a Protectli box six months ago. Here's the real breakdown.
Hardware cost was one-time. Untangle's annual subscription was more than the hardware. Management is more hands-on, but I don't miss the upsell for every basic feature. The CLI is powerful, and the package system (like pfBlockerNG) is free and deeper than Untangle's add-ons. Support is community forums, not a ticket line. That's a trade-off. You need to be comfortable digging in.
For a straightforward firewall with VPN, basic filtering, and no per-user fees, pfSense wins on pure ROI. If you need a polished GUI and dedicated support for every little thing, stay with Untangle. I prefer control over convenience.
I'm the de facto IT manager for a 60-person professional services firm. We run a mix of on-prem and cloud, and I've had both Untangle NG Firewall (now Arista) and pfSense in production across a couple of my last roles.
* **Total Cost of Ownership:** pfSense CE is free, but the hardware is a real cost. For a solid Protectli or Qotom box with AES-NI for VPN, you're looking at $400-$800. Untangle's annual subscription starts around $500 for basic features on a small office and easily doubles or triples with add-ons and per-user filtering. At my last shop, pfSense paid for its hardware in under 14 months.
* **Support Model:** Untangle gives you a support ticket. pfSense gives you a forum and docs. If your network is critical and you lack deep networking time, that Untangle ticket is a concrete business expense, not a luxury. I've gotten same-day fixes from them. With pfSense, you are the support.
* **Feature Depth vs. Polish:** Untangle's GUI is more guided, especially for reporting and web filtering policies. pfSense's packages like pfBlockerNG (for DNS/IP blocking) and Suricata (IDS) are more powerful and granular, but require more comfort with concepts. You trade a polished dashboard for raw control.
* **Performance & Throughput:** On identical hardware, I've seen pfSense handle more simultaneous VPN connections and higher throughput with inspection enabled, simply because you can strip it down to exactly what you need. Untangle's overhead from its all-in-one packaging can hit you on lower-end appliances.
My pick is pfSense, but only if you have the time and foundational knowledge to be your own support engineer. If the office needs a set-it-and-forget-it appliance with a clear path to vendor help, Untangle is worth the subscription. To make a clean call, tell us how many VPN users you need concurrently and your tolerance for downtime when something breaks.

Spot on. That subscription creep was the main driver for me too. The moment they put basic reporting behind a higher tier, I was out.
Your point about the CLI is key. Untangle abstracts everything away, which is fine until it breaks in a weird way and you can't see the pipes. With pfSense, you can drop to the shell and actually fix things.
The forum support works because the user base is massive, but you're right, you need to be willing to search and read. You won't get a hand-holding case number. For a small office where downtime is measured in coffee breaks, not revenue, that's an acceptable trade for the zero recurring cost.
