Cons
"I'm not sure if it's something that they already have or are developing something, however, we need some dedicated features for container security.""The cloud features and integration could be improved.""Maybe they could make some features more accessible, such as a way to translate directions between two networks that share the same subnets.""The support we receive when we need to upgrade is not satisfactory and has room for improvement.""We would like to see an upgrade to the VPN feature, we are using the VPN from outside of our office and there is a limitation to 10 connections, more connections would be suitable.""It's my understanding that more of the current generation features could be brought in.

More Fortinet FortiGate Cons →

"There is some room for improvement in the support.""Right now, all the features meet my requirements.""The support could be improved, Fortinet's response time is very slow. Setting up the VPN could be made much easier, especially when deployed with Azure.""Fortinet's central management needs to be improved.

Right now, FortiManager only manages the configuration of FortiGate.""For monitoring purposes, we don't have any option to monitor the ISP link.""FortiOS could provide a more detailed analysis of the network and connected devices.""The implementation could be simplified.""The product needs a feature that allows users to create another site on a VPN."

More Fortinet FortiOS Cons →

"OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server.""There is room for improvement in SSL inspection.""The solution would not be suitable for anything large-scale.""OPNsense could improve by making the configuration more web-based rather than shell or command-line-based.""On the customer-side, because I'm a small business, I need a cheaper or free solution option.""I think the most important thing is that it should be easily accessible, but currently, that doesn't seem to be the case. We need a hardware platform that's based on common standards and open computing principles, which would be like a commodity and benefit us greatly.""The ability to set the VPN IP address would be a welcome addition.""You will need additional training before you can actually start to use it."
