The solution is stable apart from the IPS engine issue, so I rate stability a seven out of ten. Stability depends on the operational team. If you have a good operational team that knows what you are doing, you always gain stability with most of your solutions. But if you have an operational team that is not so strong, you will always have issues with that solution because they will keep making human errors that will keep disrupting the services you offer. For example, in 2021, I was working as the cyber delivery manager for MTN, and I was managing the FortiGate infrastructure. In that one year, I never had any incident on FortiGate. But after I left, they started having frequent issues because of human errors. From a management perspective, if I were the CTO during that period, I would assume that FortiGate Firewall is not a good firewall. But that is not the case. It is the person who handles it that determines the stability. If you know how to do your health check properly and how to output the firewall properly, I'm sure FortiGate will be stable. I'm rating the stability as seven just to be in the middle. If it's being handled by a less experienced operational team, I'm sure you will have issues because they always perform changes, they don't know when to perform the kind of change they are performing, and that might disrupt the services. But if I rate FortiGate based on myself, I give it a nine out of ten.
