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.
Rohit Ghorpade - PeerSpot reviewer
Cloud Network Engineer at a insurance company with 5,001-10,000 employees
Identity-based perimeter control has improved security and supports reliable remote access
Currently, we are working with vendors such as Palo Alto Networks PA-Series, Cisco, Check Point, and Citrix. Palo Alto Networks PA-Series is a better firewall. Deep packet inspection and threat prevention basically comply with whatever traffic is incoming and outgoing through the firewall. I do not think anything improvement is required. The thing is that Palo Alto Networks PA-Series works mostly on a license-based model. If you want to utilize any feature, you have to purchase the license. For example, URL filtering requires a license purchase. It simplifies the implementation because LDAP server profile can be integrated. Basically, that simplifies the implementation of access rule or security policy.
