Pros

Cons
"Fortinet FortiGate could improve by having more storage in the hardware for log data.""​It needs to improve its ISP load balancing.​""The platform's interface could improve.""The updates Fortinet provides are sometimes unstable.""Technical support needs to be improved.""I think there could be more QoS features""Lacks training for new features.""If they had better integration with security products, such as Cisco ISE or Rapid Threat Containment, then it would be an improvement."

More Fortinet FortiGate Cons →

"The report and policy optimization tools can be improved in the next release.""Fortinet FortiOS can improve the monitoring function, it could be more accurate, easy to use, and understandable.""It should also manage the local DSCP network.""The pricing of the product is too high.""The central management can improve in Fortinet FortiOS. It is sometimes difficult to manage all the devices.""Fortinet FortiOS could improve by having better authentication methods with Microsoft or Google Services.""The signature discs, compared to Palo Alto, aren't as good. It takes more time to get the signature updates.""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."

More Fortinet FortiOS Cons →

"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 solution could be more secure.""I would like to see better SD-WAN performance.""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.""There are some add-ons that need enhancements to make management easier for users, especially the reporting features. Some reports don't show the level of detail I'm looking for, and I've had trouble installing certain add-ons, especially for Internet bandwidth shaping within my company.""An area for improvement in OPNsense is the hardware, which needs to be updated more frequently. DNS blocking is another good feature I want to be added to the solution. pfSense has a peer-blocking feature that I also want to see in OPNsense.""I would like better documentation concerning the provided packages and their integration.""The IPS solution could be more reliable."

Pricing and Cost Advice
