Process-Level CPU Visibility: Introduce detailed CPU-usage metrics per subsystem (e.g., IPS engine, logging) so administrators can quickly identify and address performance spikes.

Analytics with FortiAnalyzer. Being able to pull in logs not just from our FortiGates but from all our other firewalls and then get them in one view has been a game changer. Whether I’m building an executive dashboard or doing a deep dive forensics session, I get everything I need without navigating consoles.Straightforward Application Control. FortiGate spots and blocks unwanted apps (eq. like BitTorrent or streaming services) with accuracy. Segmentation with VDOMs. We’ve carved our data center into four logical ‘mini-firewalls’ enterprise, core, billing, and WAF—all on one box. Each has its own rules and logs, and any traffic between them still gets inspected. It’s like having multiple appliances without the extra hardware. Always-Up-to-Date Threat Feeds. Daily signature updates and AI-driven threat sensing mean we’re blocking the latest vulnerabilities almost as soon as they’re announced.

Quotes from Members

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

Pros

"There are great templates, so you don't have to customize them if you don't want to. You do have the option to custom create some folders and some reports, however, with what is there, you don't really need to go through extra effort, as they already give you a lot of predefined views of reports and so forth."

"The interest of the Fortinet FortiGate appliance is the ability to manage quickly and easily the different functionalities."

"There has been no attack on our servers after we configured the FortiGate IPS."

"It's features are highly customizable."

"We always support customers and recommend buying Fortinet; it is a better, more stable, and relatively cheaper product than Cisco."

"The most valuable features of Fortinet FortiGate are the ease of use and there are several operating systems that can include the hardware capacities. In the newer releases, the resources were more useful because they were included in the operating system."

"FortiGate is easy to configure. We configured one of the units and sent it to Indiana to be installed. We asked them to give us a call when they got it, so we could help them through the process, but they called us back to tell us it works great."

"Virtual Domains (VDOMs) are a feature that we found valuable."

More Fortinet FortiGate pros

"The fact that the setup is so easy is one of the solution's great selling points."

"We use Kerio Control for controlling access to the web, and to protect the inside of the network."

"All of the features of Kerio Control are equally good. Most valuable to us are the firewall rules, the intrusion detection system, and IP address features."

"Compared to other solutions, accounting and live monitoring of firewall status are very good features in KerioControl."

"Only trust in the product."

"Kerio Control is easy to use and provides the ability to deliver customized solutions."

"I like intrusion detection and prevention and bandwidth management. The routing part is also awesome. It is a good firewall. We never had a major breach from outside. We've never been impacted by ransomware, and our systems have never been infiltrated."

"Kerio is user-friendly, it's flexible, and can be used on different kinds of infrastructure."

More KerioControl pros

"The stability of Palo Alto Networks CN-Series is excellent."

"The app inspection is very helpful for network security."

Cons

"Tunnel flapping was one of the major things I had seen wherein your internet link remains but your VPN tunnel is down. However, since I got a fix from the TAC team, I have not noticed it, but the customer complained a few times that they couldn't access the internet because of this problem."

"I would prefer to have more detailed logs within the FortiGate products themselves rather than relying on a separate tool."

"I have an issue with NAT only, in that I can't allow traffic from outside to inside using a NAT pool."

"They should make the rule sets more understandable for the end user."

"The customization could be improved. Cisco, for example, is much better at this. They need to work to be at least as good as they are."

"The speed of synchronization between FortiManager and FortiGate could be improved, but that could be because we host them in Azure."

"If I had any criticism that I would give FortiGate, it would be that they need to stop changing their logging format. Every time we do a firmware upgrade, it is a massive issue on the SIM. Parsers have to be rebuilt. Even the FortiGate guys came in and said that they don't play well in the sandbox."

"It is very expensive, and their support is not very good. I hope that their technical support will be better in the future."

More Fortinet FortiGate cons

"Because of Kerio Control, we failed to protect kids from such content, and we expected them to respond to it with the urgency it required, but their support was pathetic."

"The GUI should be changed because it remains the same consistency across versions. However, those who have been using KerioControl for a long time may be accustomed to the current interface. Installing a new version in the same location makes it easy to find, but overall, there are no notable changes between versions."

"If I would suggest anything, it would be to expand on its multifactor authentication to be a little bit more user-friendly. They should do multifactor authentications for the client itself perhaps, rather than served on a webpage, in a page hijack, that might be more user-friendly, but I don't have a lot of complaints about it. It's doing its job. You have to have a certain amount of skills to configure these things anyway, the ones that we use on-site doing point-to-point, and we've been tricked up a few times with their interfaces."

"I have had a few issues with HTTPS decryption. The solution also does not show the actual user's Internet usage."

"I can no longer renew my subscription directly with GFI but we have to go through third-party resellers like CDW. The first time I did it with CDW. I went to CDW and it was almost like they didn't even know anything. They didn't know what package I was supposed to get. Then after I got it, it took almost five days to get everything working."

"It has a VPN back to our data center but I don't think it has increased the number of VPN clients extended to those outside our environment"

"The upgrades make the network slower."

"The overall speed needs improvement. Internet connectivity speed needs to be improved somehow."

More KerioControl cons

"I'd like to see more IOPs features."

"Palo Alto Networks CN-Series could improve on its pricing as it is quite expensive."

Pricing and Cost Advice

"The price of Fortinet FortiGate is better than Cisco, Check Point, and Palo Alto. In terms of pricing, it's probably a better-priced firewall solution overall."

"The license is too expensive to renew. The license renewal process is also complex."

"The price is fair compared to the other competitors."

"There is a licensing fee; it is on a yearly basis."

"It's very competitive."

"The price of Fortinet FortiGate is affordable. Most of our customers are on a three-year license to use the solution. All the features and support are included in the price."

"I would say that all things considered, the pricing is pretty good."

"Fortinet is reasonable in pricing and licensing. Overall, FortiGate is affordable. The licensing fee can be a little high, depending on the budget for your project."

More Fortinet FortiGate pricing and cost advice

"Its initial cost is less as compared to other products. It becomes a bit costly when you pay for the products that you don't use. We paid for almost all the products through subscription, but we are using only a few products. We use EndPointSecurity, Kerio Connect, WebMonitor, and LanGuard. We don't use the rest of the products."

"GFI has made a stupid decision regarding small office licensing. For offices where there are only three to five employees and had five years towards a five user product, they now force these customers to a 10-year user license. I really don't understand it. It's a stupid decision for the small offices who want a good solution for security because they'll probably decide to go to another product. Why should they buy something that they don't use?"

"It's very affordable."

"It's too expensive. The license, in the last year or so, has gone up by over a £100. We're almost being out-priced by the annual license at the minute."

"I pay approximately $50 for the solution on an annual basis."

"I am living in Iran and we cannot buy the product from Kerio because of sanctions."

"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."

"Pricing is good, but the licensing took a lot of time."
