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.

Pros

"The stability of Palo Alto Networks CN-Series is excellent."
"The app inspection is very helpful for network security."
"Mainly, it is very easy to understand, and the logs are very good."
"Palo Alto's App-ID is what differentiates it from other competitors."
"The most valuable feature of Palo Alto Networks K2-Series is the configuration, it is very clear."
"I have found the threat profile feature valuable."
"The technical support has been excellent; we are very satisfied with the level of service they provide, and it is one of the main selling features of the product because, compared to the competition, support is excellent across the board."
"The scalability of the product is quite high."
"Regarding traffic visibility features and Advanced Threat Prevention aspects, I would assess these functions as awesome; it's unparalleled, not just for K2-Series, but in general for Palo Alto."

Cons

"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
"I'd like to see more IOPs features."
"Palo Alto releases a lot of bug fixes for their firewalls, which means it's necessary to do frequent upgrades. They should work on decreasing their bugs so that upgrades aren't needed so often."
"The solution's commitment time could be reduced as it often takes a lot of time to execute."
"Palo Alto has many other products. It would be nice for these products to be centralized under one tool rather than having to jump from tool to tool."
"The password function of the solution could be improved. Additionally, some of the processes take too long to complete."
"Because we are using the hardware, we are not able to scale. On the VM, it is scalable, but we have got stuck on some areas."
"The eight-by-seven support is not good in that case if you need it often or at times when it is not available."
"The licensing cost is a typical complaint with many clients. The solution is expensive."
"The technical support, and how they provide it to the client, needs to be improved."
