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

"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"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."
"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."
"It has been stable so far."
"The most valuable features are the virtualization of the firewall and the antivirus."
"The application ID on the Palo Alto Networks K2-Series is able to understand the application traffic, and WildFire is also good."
"The scalability of the product is quite high."
"As long as the solution is kept updated, it's pretty stable."
"Palo Alto has better and finer controls than, say, Cisco or Check Point."
"This is a product that I would recommend."
"Overall product rating: Nine out of ten."
"The solution offers effective security features such as HIDS (Host-based Intrusion Detection System) in global products."
 

Cons

"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."
"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."
"The technical support, and how they provide it to the client, needs to be improved."
"The scalability of Palo Alto Networks K2-Series is good. It is good for larger environments over smaller ones."
"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."
"Threat prevention could use improvement."
"In the past, we've had trouble with Palo Alto's application filtering not getting it right. I would not be recommending layer 7 application filtering yet."
"Its networking features could be better."
"We had some issues with upgrading in the past. They could make the process easier."
 

Pricing and Cost Advice

"We got a much cheaper price than that provided by Fortinet right now."
"On a scale from one to ten, with one being low and ten being high price, I would rate the price of Hillstone T-Series at three. There are no additional costs other than renewal costs."
"Palo Alto firewalls are very expensive."
"It would be nice if they lowered their prices for small businesses."
"The overall price of Palo Alto Networks K2-Series could be reduced."
"This is an expensive solution, although you will get value for the price."
