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

"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."
"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."
"It has been stable so far."
"We found some limitations with Fortinet FortiGate, and we are satisfied with Hillstone T-Series right now."
"Simple integrations with the domain controllers and other inventories"
"The solution is reliable and scales well."
"Palo Alto has a unique solution for DNS security, which is very good."
"Palo Alto firewalls are scalable enough. We have about 110 employees in our company, and we are about to expand to 130."
"Palo Alto firewalls are scalable enough."
"Everything I could possibly want has already been implanted in the new version."
"The scalability of the product is quite high."
"The thing I like the most about Palo Alto is that the IPS system is the strongest you can get."
 

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."
"Licensing is not cheap."
"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."
"They have a very good technical support team, but I think there are some communication issues due to language differences."
"We had some issues with upgrading in the past. They could make the process easier."
"They could improve by providing more features in the solution."
"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."
"Palo Alto doesn't have that extended visibility to the end point in their firewalls."
"I cannot think of anything specific to improve at the moment."
"It would be really helpful to have dashboards that provide information on IOC blockings such as where and how many. It will also be good to know how many hashing files have been reported. It would also be nice to have easy access to this information. Otherwise, it's a painful, manual task."
"From a cost perspective, I'd rate the solution two out of ten. I am trying to avoid Palo Alto, even though they have a very good solution, specifically due to the cost."
"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."
 

Pricing and Cost Advice

"We got a much cheaper price than that provided by Fortinet right now."
