Firewall deployment has secured mission-critical public apps and simplifies Linux-based management
The best features IPFire offers include its very intuitive nature because, even though it has a Linux back-end, in terms of configuration, it has a very rich GUI interface. The GUI and configuration features of IPFire have made my work easier and more efficient because their positioning and the sequence with which I follow is easy. In terms of all the processes, what you need to do at first and the next thing that you need to do is clear. The GUI is well arranged in sequential order, so you can follow that from whatever you want to do until you get the target objective. IPFire includes features with a very robust and rich community that is very much valid in terms of content. IPFire has positively impacted my organization by giving us some mileage. At least, a lot of organizations now know that we have a solution that can deliver the same value.

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

"IPFire has prevented any kind of hacking and enables us to comply with customer requirements."
"I would rate the stability as ten out of ten for IPFire."
"Regarding IPFire's AI capabilities, I think they are quite focused; in all the deployments I have done, I have not had any incidents or breaches."
"Simple integrations with the domain controllers and other inventories"
"Overall product rating: Nine out of ten."
"The company is inventive and always adds a lot of great features."
"Overall, this is a very simple and very effective firewall, and I am satisfied with it."
"My advice to someone considering this solution would be that it's okay to spend a bit higher on your security products because Palo Alto is a bit more expensive than other products, but it is definitely worth it."
"One of the most valuable features is Palo Alto's firewall management. We find it easier to manage the firewall centrally."
"Overall, this is a very good firewall and I would recommend it."
"I would say Palo Alto, overall, has a better, more reliable product line."
 

Cons

"I would rate IPFire 8 out of 10 because I do not think there is any solution anywhere in the world that is 100 percent efficient."
"Accessing the internet was a bit complicated."
"The graphical interface could be much better."
"The ease of management and configuration should be improved."
"Because we are using the hardware, we are not able to scale. On the VM, it is scalable, but we have got stuck on some areas."
"They could improve by providing more features in the solution."
"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."
"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."
"The scalability for on-premises version is limited as it depends on the model."
"It would be nice if it could easily be integrated with Elasticsearch or Nagios."
