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.

IT Manager at Zubair Feeds

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

Cons

"Technical support has issues with knowledge base at the first tier. It sometimes takes hours of explanation before support fully understands and can troubleshoot or escalate problems."

Pricing and Cost Advice

"We pay an annual license fee. It is rather expensive so I would like to perhaps see a drop in price in the future."
