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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It has been stable so far."
"We found some limitations with Fortinet FortiGate, and we are satisfied with Hillstone T-Series right now."
"The only firewall able to monitor traffic from a CCTV network. Can detect unauthorized devices plugged into the network, which standard firewalls can't do."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"Hillstone supports IOT setup and detecting intrusions from IOT or CCTV connectivity, and with this solution, we can also detect unauthorized devices plugged into the CCTV network and sound the alarm to the administrator."
"Palo Alto has better and finer controls than, say, Cisco or Check Point."
"Palo Alto has a unique solution for DNS security, which is very good."
"The thing I like the most about Palo Alto is that the IPS system is the strongest you can get."
"It's easy to configure."
"We are happy with the solution and our return on investment has been extremely high."
"Palo Alto firewalls are scalable enough."
"This is a product that I would recommend."
"The scalability of the product is quite high."
 

Cons

"Licensing is not cheap, but there are customers who will buy because they understand that this has a cost involved and they will cater their budget for that."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"Another loophole with Hillstone T-Series is that when we connect through WiFi and turn our hot spot on, all who connect through the hotspot get all the functions, and the security does not work."
"Licensing is not cheap."
"They should implement the features that the other firewalls have."
"There are a lot of bugs in this solution."
"The licensing cost is a typical complaint with many clients. The solution is expensive."
"Sometimes there are interactions with support or the provider that are not ideal."
"The scalability for on-premises version is limited as it depends on the model."
"If we have issues, they take anywhere from two days to a week to respond. I even wrote to their CEO because there was no response. When it comes to support, this is the worst company."
"The reporting functionality in GlobalProtect needs to be improved."
"The password function of the solution could be improved. Additionally, some of the processes take too long to complete."
