Featured Reviews

MS
Associate Director IT Operations at Procento
Single-pane management has simplified firewall control and has improved risk mitigation
I would not say that Fortinet FortiOS is not very scalable. Generally, what happens is that for enterprises, we hire consultants who do the capacity planning and sizing to determine what kind of firewalls to put in place. At the same time, it is not only the number of users; it also depends on the number of WAN links coming in and everything, because we have been using Fortinet for bandwidth shaping and many other bandwidth-related functions. They should improve their machine learning AI capabilities of Fortinet FortiOS because there is too much competition. Other players are also improving and making a lot of changes in their UI and overall operating system.
IhorShtanko - PeerSpot reviewer
Technical Consultant Of Juniper Networks Division at MUK
Secure branch connectivity and automation have improved, but clustering and support still need work
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.
