Network Administrator at THK Co Ltd
Faced hardware limitations and setup challenges but have improved network protection over time
I spent much time finding exact firmware on Aruba which was working with these guns, but it is not optimal because it is not the latest version, so there could be potential security problems. We decided to replace those access points with another one. I personally have trouble because I don't know the exact life cycle of Fortinet FortiGate-VM boxes. I don't know if the life of boxes is five years or something else; we moved from our previous company, which sold us to other companies. Before 10 years, we had a special department that took care of core networks, including firewalls. After that, this responsibility fell to me and my colleague. It is not easy to set up these Fortinet FortiGate-VM boxes properly because we didn't have previous experience with this kind of solution. At first, we set up only a few rules that were not secure enough, and over a couple of years, we improved the settings and security of these Fortinet FortiGate-VM boxes. Currently, I have one Fortinet FortiGate-VM that needs to be replaced next year, and this box is not so powerful, so I need to redirect some traffic to another Fortinet FortiGate-VM. It is stable, but because the CPU processor of this box is not powerful, I need to redirect some traffic to another box. In the future, I need to choose a higher-level box to prevent potential troubles with the power of this box.

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.
