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.

Automated breach prevention has protected critical workloads and keeps external attacks blocked
I am familiar with SonicWall TZ. I have done a POC of TZ but I have not worked extensively with it. I have worked with the 2600 firewall and then the 3600. These are the models which we have worked with.SonicWall NSa was an on-premises solution. The two firewalls which were in production, in the data center and on the LAN side, were both on-premises solutions. We had a pre-decided budget under which we would purchase the firewall. All parameters including security, high availability, and budget concerns were covered with SonicWall NSa being implemented at that time. SonicWall NSa is a user-friendly product that is easy to configure, and it is easy for network personnel and firewall administrators to work with. Even the L1 team captured and learned this firewall effectively, helping us resolve all parameters related to high availability firewalls within budget-friendly costs. I rate this review a nine out of ten.
