For what reason? Are there any problem with Pfsense ?
Not problems, pfSense is a good product. The biggest "problem" is the lack of vertical integration with hardware. With the UBNT we get software custom made for the specific hardware, and support. So we don't have to do our own installs, and don't need random third party software. It's one, inclusive package that is well known and tested both in the field and by the vendor. pfSense is software only and as a software firewall would be at the top of my list. But we deploy hardware and the benefits are the lower cost, better supported hardware with massive supply chain are pretty impossible to beat.
And the central monitoring features of UBNT carry a lot of value. We get centralized visibility.
Thanks for your opinion, I always learn of them.
