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.

Featured Reviews

Secure branch connectivity and automation have improved, but clustering and support still need work

Technical Consultant Of Juniper Networks Division at MUK

I think Juniper SRX Series Firewall could be improved or enhanced because maybe a year or two ago, Juniper began producing new boxes such as SRX 1600, SRX 2300, and SRX 4300 and 4700, which are excellent products. They are only one unit high but have very good performance and a lot of different ports, supporting from 1 gig to 100 gig ports. Juniper also has series SRX 300, but it is an old firewall and not very powerful. I believe that maybe in a year, they will transition to another series, such as SRX 400. However, the functionality of Juniper SRX Series Firewall remains the same. The differences involve performance, quality, number of ports, and types of ports in different models of Juniper SRX Series Firewall.

Has provided strong traffic visibility and efficient policy management for advanced network environments

Principle Cloud Architect at a tech services company with 11-50 employees

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.
