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 found some limitations with Fortinet FortiGate, and we are satisfied with Hillstone T-Series right now."
"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."
"We installed Hillstone T-Series after a ransomware attack. The dashboard and user interface are very good."
"It has been stable so far."
"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."
"This is a product that I would recommend."
"It is a stable solution."
"Simple integrations with the domain controllers and other inventories"
"Overall, this is a very simple and very effective firewall, and I am satisfied with it."
"We've found the solution offers us good stability."
"The most valuable features are the virtualization of the firewall and the antivirus."
"The most valuable feature is availability."
"Overall, this is a very good product that is doing well in the market here."
 

Cons

"They have a very good technical support team, but I think there are some communication issues due to language differences."
"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."
"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."
"The tool needs to improve integration with more products from other vendors. I would like the product to add threat intelligence features as well."
"Palo Alto doesn't have that extended visibility to the end point in their firewalls."
"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 URL Filtering module needs to have more categories added to it."
"When it comes to renewing the solution, they tend to try to jack up the pricing."
"The solution needs to constantly be adapting and updating."
"Sometimes there are interactions with support or the provider that are not ideal."
"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."
 

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."
"The pricing is expensive."
"If you compare K2-Series' quality with its price, I think it is reasonable."
"This solution is expensive compared to other, similar products."
"This product is designed for large companies. The price would not be suitable for a small or medium size company."
"Palo Alto firewalls are very expensive."
"The price of the solution is expensive."
"This is an expensive solution, although you will get value for the price."
"It would be nice if they lowered their prices for small businesses."
