We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"It is a safe product.""FortiGate firewalls are user-friendly, and I like the security profiling features.""The product offers very good security.""It is useful for protecting and segregating the internal networks from the internet. Most of our customers also use the FortiGate client to connect to their offices by using the VPN client, and of course, they usually activate the antivirus, deep inspection, and intrusion prevention services. They are also using it for web filtering and implementing various policies dealing with forwardings, NAT, etc.""​Easy to implement, and it is also reliable.​""The most valuable feature of Fortinet FortiGate is the simple configuration.""The application control features, such as Facebook blocking and Spotify blocking, are the most valuable.""The secure web gateway module and the application control module are valuable. HA operations are very easy."

"SonicWall TZ think it's a good, solid, and stable product.""We like their interface very much. It's pretty easy to use.""Access restriction and IP whitelisting are the most valuable features.""Ease of management and the VPN integration.""The performance has been very good. Overall, the solution is quite stable.""The most valuable feature of SonicWall TZ is the double authentication, where it asks for one password and again asks for a four-digit code, which changes every 30 seconds.""Most of the features are useful. It is easy to configure and easy to troubleshoot. I can see the utilization of different networks, and there are also App control features.""It protects against intrusion while allowing needed access."

Cons
"Scalability is one of the disadvantages. When it comes to scalability, you have to actually change the box. If you want to upgrade it, you need to actually change the existing box and probably you take the system off to other sites.""The cloud features can be improved.""Fortinet FortiGate could improve the user interface. There should be more functionality and options through the GUI.""The Web-filter in this solution is not very good.""Fortinet needs to overhaul its documentation.""Performance and technical support are the main issues with this solution.""As far as wanting more scalability or things in the network diagram, it's going to cost you.""Its filtering is sometimes too precise or strict. We sometimes have to bypass and authorize some of the sites, but they get blocked. We know that they are trusted sites, but they are blocked, and we don't know why."

More Fortinet FortiGate Cons →

"The solution would not be suitable for anything large-scale.""There are issues with stability and reliability.""While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet.""When using the solution at the beginning was difficult. There was a steep learning curve.""OPNsense showed me some problems when using it in different environments. The problem is integration with a virtual server.""The IPS solution could be more reliable.""OPNsense could improve by making the configuration more web-based rather than shell or command-line-based.""There are a few weaknesses. For example, there is a lack of some features that I have in certain commercial products."

More OPNsense Cons →

"From a support perspective, if we're talking tech support I think Silver Partners, Gold Partners, Platinum, whatever level, should have a different number to call. End users can call tech support over at SonicWall if they've paid for support as part of their AGSS or whatever services they bought. The end-user can call, or we can call, however, I don't want to be calling the same line that an end user's calling. I don't want the same response time. I need a different level of expertise.""The solution's pricing could be made cheaper.""In terms of what needs to be improved, I would say better load balancing and data filtering.""Pricing could be lowered slightly.""Its reporting can be improved. Currently, we cannot directly get the user names. It only shows the IP, which makes it a bit confusing because we need to use the IP to find the user. If we could directly get the name of the user, it would be better.""The solution must provide more ports.""The VPN that is available in the new version is a bit bulky and slower in speed.""I currently have two of the issues from SonicWall. One issue is that the IP is not the public IP. Sometimes it moves to an alternate source and I have to refresh the new IP then we can go on."

Pricing and Cost Advice
