Unified security and sd-wan have improved uptime and cut wan costs for multi-site branches
Users report stability issues in certain versions, which requires regular updates. Real-world attacks have also highlighted the need for urgent patching of vulnerabilities.Fortinet FortiGate, while a powerful and feature-rich web firewall, could improve in areas like firmware stability, documentation, and ease of use. The learning curve can be steep for some users. For beginners, support quality can vary, and frequent updates with occasional vulnerabilities call for careful patch management. However, once Fortinet FortiGate is configured, it remains highly reliable and efficient. Customer support needs improvement, as I find it very slow, with reports from other users reflecting that customer support is inadequate.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Fortinet has got great firewalls; they do everything, from FortiTokens for two-factor to IPsec VPNs and SSL VPNs, with a great GUI that makes it easy to use while the support is great."
"Fortigate represents a really scalable way of delivering perimeter network security, some level of layer 7 security, WAF, and also a way to create a meshed ADVPN solution."
"We find the most valuable aspect of this solution is the price."
"FortiGate's ability to perform as expected and fulfil our needs has been the most compelling feature for network security."
"The solution is stable and quite reliable; there are no bugs or glitches and it doesn't crash or freeze."
"The most useful functionality of Fortinet FortiGate is the user interface, multiple engines, and their cloud with the latest integrations, and additionally, the Security Fabric tool is very good."
"Fortigate's most valuable feature is that it doesn't need a push policy when writing rules."
"The most valuable features of Fortinet FortiGate are the different types of profiling. It has been the most effective for me. The WAF and the antivirus profile are the most effective in network protection."
"It just works, it does what it is meant to do."
"We also like the security. We can control what sites users can go to and we can make sure that where they're going is appropriate and that it's work-related."
"The solution is user-friendly."
"Kerio is a lot clearer to set up to do particular things, whereas when I do it on a Cisco or a FortiGate I have to go fight with it per week sometimes to do something I can do in 20 minutes on Kerio."
"Kerio Control can be scaled easily."
"The solution has also saved us a lot of time in managing security."
"The firewall appliance itself is the most valuable feature."
"I did not face any issues with stability while using the tool's trial version."
"The app inspection is very helpful for network security."
"The stability of Palo Alto Networks CN-Series is excellent."
 

Cons

"It should come integrated or have its own type of network monitor tool in a module. There should just be one package, and you are good to go."
"The solution is quite expensive and I'd like to see the cost reduced."
"I use the FortiGate 60D model and realized the 300Mbps bandwidth limitation. Because it is a product that offers many services, I think it could have greater bandwidth capacity."
"At first glance, the interface for the device is very confusing."
"I have to say that the initial setup was complex. The deployment took a few days to get set up. Initially, we were using an IPVanish. We switched to this tool since we thought it would be easier. But it turns out it wasn't easier to set up and run."
"My only complaint about FortiGate is a lack of QinQ VLAN tunneling. I haven't found this feature in any Fortinet product. You can do this on all Cisco routers, including the smaller models. However, QinQ isn't available on the biggest, most expensive Fortinet units. They still don't have that. I think now we're on software version 6.0, and they still haven't found a solution for QinQ. It isn't a dealbreaker, but that's my main complaint."
"Some features of Fortinet FortiGate are actually fee enabled that are inconvenient for deploying in production. Other issues relate to isolation with Cisco products and your server."
"Fortinet FortiGate IPS could improve the VPN. There are times it is slow."
"The logs could be improved for better clarity."
"If I would suggest anything, it would be to expand on its multifactor authentication to be a little bit more user-friendly."
"Kerio Control could improve content filtering."
"If you have to dive deeper into the firewall or any other features, then you really have to read up a bit about how to set it up properly."
"Filtering of pages and greater personalization in services need improvement."
"I would like it if the interface section had multiple failovers. Although I do have three connections, just in case our physical cables get disconnected, I can only set up one failover as a backup. So, if for some reason our fiber and our AFM went down together, I would have to have it search for our 4G modem. I'd love to have extra backups running."
"I would like to be able to inspect https packets for the purpose of virus scanning."
"The one thing that did put me off of the solution was that, after they were taken over by GFI, the licensing and a few other items have gotten very complicated."
"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."
"I'd like to see more IOPs features."
 

Pricing and Cost Advice

"The support subscription for the solution is annual. You are paying for support and there are two levels of support, professional and advanced."
"It has been two years. I don't remember the actual price, but it was affordable. We buy the boxes and then use the license for three years."
"They are more expensive than others."
"Fortinet FortiGate has different licensing models, depending on what you're going to do. Services included would depend on the license model. Licenses can be renewed annually."
"Fortinet FortiGate IPS is cheaper than other solutions like Cisco or Check Point."
"I'll rate FortiGate's pricing a five out of ten since it is moderately priced."
"A year or two years back, its price was competitive and reasonable. That was one of the reasons that people easily switched to Fortinet. Over the last two years, the prices have increased drastically. However, the prices of others have also increased. An advantage is there from the price point but not as much as it was previously."
"Fortinet FortiGate as a less expensive solution than Palo Alto."
"There's a one-time fee. For KerioConnect, it's just a server. With KerioControl, you have an option. You can virtualize it on a VMware system or have the hardware. I think mid-range or desktop KerioControl hardware could cost around 2000 dollars for a 25 user client. You need annual renewal for additional features like antivirus."
"Pricing is good, but the licensing took a lot of time."
"Search and compare."
"The biggest advice that I could probably give people is when you buy the solution be prepared to either buy the unlimited license or buy more licenses than you think. Each user license gives you one employee and each a user gives you five devices. In the world nowadays where everybody has a cellphone, tablet, desktop, and laptop, that's four devices. You still get one more device per person. That covers your servers and back-ends."
"KerioControl's pricing is good."
"I am living in Iran and we cannot buy the product from Kerio because of sanctions."
"It is priced low enough for entry-level, but it has the power to grow with a company without them having to replace it."
"The pricing is in-line with our expectations in terms of the quality that we get for it."
