Principle Cloud Architect at a tech services company with 11-50 employees
Has provided strong traffic visibility and efficient policy management for advanced network environments
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.
Zsolt Jónás - PeerSpot reviewer

Advanced GUI and layered security have supported compliance and simplified intrusion prevention
I haven't had a task that I couldn't solve with Stormshield Network Security. The active-active high availability solution would be beneficial because currently, if you build a high availability solution with Stormshield Network Security, you have a main device and another one is a backup device. The HA can switch between them, but it would be good to have a master-master solution, not just a master-slave one. I could set a URL that I can call to update the DNS record. Currently, Stormshield Network Security devices support DynDNS, which is not a usual feature request from a server environment. I have my own solution instead of DynDNS because I don't prefer it, so I have my own service for that. However, the GUI does not support using a custom service instead of DynDNS. I had to solve it in the console on Stormshield Network Security device, but it would be much better if it was reachable on the GUI. I had to figure out a trick for the IPsec configuration. In the IPsec config, we have to provide the remote side's IP address, but it's always changing. This means that an office, for example a company that has an office but without a fixed IP address, cannot be used with IPsec VPN.

Quotes from Members

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

Pros

"The company is inventive and always adds a lot of great features."
"I would say Palo Alto, overall, has a better, more reliable product line."
"The most valuable features are the intuitive user interface, ease of use, and reporting."
"The customer service and support are really good."
"The most valuable feature is availability."
"Overall product rating: Nine out of ten."
"This is a product that I would recommend."
"Palo Alto detects a lot of cybersecurity threats, which has been great."
"Filters and URL filtering helped us to optimize our bandwidth."
"Stormshield is pretty robust, compared to other products like Fortinet, as you get more security with Stormshield and spend less money."
"Customer service is very good, because of their presales support helping me with initial setup I decided to go with NetASQ in the first place, and support after the sale has been equally good as well."
"This solution is quick and easy to configure."
"Fortinet, Dell SonicWall and Check Point because these products offer a wide range of features that are not available with Netasq."
"It's an easy, straightforward management platform to use."
"The most valuable features of this solution are the URL filtering database, which is great and contains all internet categories, the highly scalable interface that I can turn into what I want including hybrid, bridge, or router mode, the security with no back doors that is more secure than other solutions, and the hardware performance that is also better than others."
"The solution has improved my organization because I can see what traffic is happening and I can use it to block and prevent attacks."
 

Cons

"There are a lot of bugs in this 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 Networks K2-Series is an expensive solution, the price could be reduced."
"The ease of management and configuration should be improved."
"When it comes to support, this is the worst company."
"Palo Alto doesn't have that extended visibility to the end point in their firewalls."
"They should lower their prices for small businesses."
"Sometimes there are interactions with support or the provider that are not ideal."
"This solution has a big problem with web filtering and it needs to be improved."
"The product must improve its pricing."
"The pricing is increasing, and I would say it is a bit expensive."
"The technical support for this solution in Poland is not good."
"One thing, though, is that not all the fields are activated yet and we were informed that it will take at least one month."
"The stability is not that good based on my experience. We have a lot of disruptions when it comes to Stormshield."
"An application firewall like other next generation firewalls have."
"Being more cost effective. I went with a pair of Watchguard M300 recently when buying a new firewall cluster for our own use because it was way cheaper than NetASQ/Stormshield N700 while being faster, and it offers true multi-master firewall clustering if needed."
 

Pricing and Cost Advice

"We bought a three-year license, and we renew it whenever it expires. The price could be better. It's always very expensive."
"We chose Stormshield for its price, as the Azure firewall was too expensive."
"The price of this solution and the price of support are ok."
