There are a lot of features that we like within the solution. The resources or performance of the firewall is very good. However, the real selling point is the fact that the solution offers so many features, it gives our clients a lot of extras that they can work with. There's a lot on offer.

All networks are security-driven, we get throughputs and security. We feel that the people at Fortinet are easy to deal with from a support standpoint. If they need to jump in and help us, they're very willing to do that. Their email filtering, their data loss prevention, their intrusion prevention, type of products in the newest OSs has been outstanding.

You can enable and disable certain modules in it. However, with disabling, nobody can really tell us if that module is disabled.

Right now, it's very trendy to integrate everything into the cloud. This solution would be more effective if they did more integration in that regard.

The support is not very good, but the product is stable so it is not so much of a problem.

While it is a solid solution, there are some product limitations which exclude it from deployment in some situations.

It could more scalable for the lower end users.

The main challenge with Fortinet FortiOS is integration with third-party solutions. I don't see any other areas for improvement. Nowadays, all products work well for 50-60 percent of needs. We must only fulfill 60-70 percent of client requirements because they don't use 100 percent of product features. Banks and financial sectors might need more security features. I don't work much in banking, but they often use multiple products for different security layers, not just firewalls. They might use various products or APIs for different purposes. In the end, clients use the products that suit their needs.
