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.

Pros

"I would rate the stability as ten out of ten for IPFire."
"IPFire has prevented any kind of hacking and enables us to comply with customer requirements."
"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."
"Overall product rating: Nine out of ten."
"Prevention of evasive threats is one of the best tools I've encountered."
"I have found that Palo Alto Networks K2-Series has the best security. They are more user-friendly, older firewalls used to have to be configured using the command-line interface, but in this solution, it can be done in the GUI."
"It's a very good product, simple to use."
"The company is inventive and always adds a lot of great features."
"I like the tool's WildFire feature."
"The most valuable feature of Palo Alto Networks K2-Series is the performance which is above their competitors. The throughput they have delivered is good. When we used other solutions they failed the deployment when we were using different rules. They have a theory perform performance light and performance degradation. However, Palo Alto Networks K2-Series never fails in that scenario."
"The most valuable feature is availability."

"They should lower their prices for small businesses."
"The ease of management and configuration should be improved."
"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."
"The product should get frequent updates allowing us to add new signatures."
"The licensing cost is a typical complaint with many clients. The solution is expensive."
"They should implement the features that the other firewalls have."
"The solution needs to constantly be adapting and updating."
