High availability routing has secured our network and delivers reliable support every day
One downside of Netgate pfSense Plus Firewall_VPN_Router is the need for a better understanding of what hardware it would run on. Right now, we're using Netgate's hardware, but I'm interested in knowing if there are other hardware options available, particularly heavier duty hardware, because the Supermicro 1537 version we have only has a single power supply, which is a shortcoming in an IT environment where dual power supplies are ideal. The pricing for the hardware of Netgate pfSense Plus Firewall_VPN_Router is steep, which is one reason I'd explore other options. I'm familiar with the costs of Supermicro servers, and I believe Netgate charges a premium for their server hardware without enough upside to justify it. The pricing is not justified.

Palo Alto Networks K2-Series could be improved, though I don't think of much. I'm unsure how widespread the adoption for K2-Series alone is. Looking at the base Palo Alto capabilities, they are going in the right direction. K2 specifically about its efficacy with all these 5G protocols, the GPRS tunneling protocol performed without many hiccups during testing. With AI, if there is a Precision AI bundle that you're planning on exploring, then that definitely needs a significant uplift because currently it doesn't work for all the known models. There are many false positives that need to be addressed. While it's still ahead of its competitors, on the AI security side, there is quite a room for improvement.
