Manager, Information Technology Operation/Presales at TechMonarch

A stable solution with an intuitive interface and quick customer service

I have been working with Fortinet FortiGate, WatchGuard, Sophos, and SonicWall. I'm not as comfortable with SonicWall because of their UI and limitations. I prefer Fortinet above all other options. When it comes to configuration, I am confident in my ability to handle various tasks, including creating policies such as firewall rules, web policies, and application policies. Additionally, I can configure VPNs and implement load balancing, among other tasks. Overall, I feel much more comfortable working with Fortinet. Fortinet has made significant improvements by integrating AI with firewalls for threat analysis and prevention. In the past 2-3 years, they have launched FortiSASE and SIEM, and they also provide SOC services. Both Palo Alto and Fortinet FortiGate are excellent. While Fortinet FortiGate comes at higher prices, the functionality and support justify the cost. They promptly resolve firmware issues and inform all support providers about configuration changes.

Offers good features like URL filtering, IPS, and IDS to users

We received an update for the tool in July. The update was provided for the tool as there was a problem with the firewall, where too much memory was consumed, and the firewall was hanging a lot. When we updated the tool's features, everything became okay. The tool only had some memory-related problems. It took the tool a month to fix the issues.

Quotes from Members

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

Pros

"The email protection and VPN features are the most valuable."

"The most valuable features are that it is very simple to configure and to manage."

"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."

"We use a southern institution that's audited for IT security and the reporting that automatically comes off the unit makes it much easier to meet compliance standards and makes it easier as far as the amount of time that has to be spent to compile that information. If you get your reporting set up correctly when you initially set it up, you just select the one you want and hit print. The auditing trail on it is the best feature."

"We were looking for the VPN feature and controlling the inflow and outflow of all the traffic within the site and across the sites. We are also using it for the VPN and VLANs."

"The most useful feature of FortiGate IPS for me is Application Control."

"The firewalls are valuable for threat prevention."

"The IPS and the application control feature are the most valuable."

More Fortinet FortiGate pros

"The most valuable feature of the Hillstone E-Series is its user-friendliness."

"The most valuable features of the Hillstone E-Series are its hardware capacity, innovation, and the throughput that the hardware can take."

"This solution has two main features that we find very valuable; a threat-intelligence option, and a web/application filtering option. The technical support team are very good and very quick."

"The most valuable feature of the solution is the ransomware protection that the tool offers."

"The initial setup was straightforward. It only took a few hours to deploy."

"The installation is easy, we have not had any complaints from our customers."

"Very reliable solution with good scalability and straightforward implementation."

"Working with the Hillstone E-Series has, from a remote perspective, allowed me to give my clients a secure connectivity."

More Hillstone E-Series pros

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

"The routing of the multiple internet physical routers I have is the most valuable feature of this solution. Instead of me physically unplugging a cable from one router to the server, if one connection goes down, it automatically switches for me. So I can have all three of them plugged in. If one goes down, it just picks up the other one automatically. There's no physical cable swapping."

"The most valuable features of Kerio Control are the IPS and traffic rules. The traffic rules are very user-friendly and the IPS is working well. Additionally, the anti-virus is effective with quick options, such as filtering."

"What I like the most about Kerio is that I can use the software appliance as a solution, so if the hardware fails for any reason then I can quickly replace it with hardware that I have in stock."

"The interface control manager where we can allocate LAN connections to certain VLANs is the most valuable feature. The other feature that's important for us is because obviously everything is remote with MyKerio, as long as the boat has an internet connection, we can log onto the Kerio and get statistics, as well as provide support."

"The traffic insight page or the administrative portal is really helpful because you can see all the internet usage down to the point where you can see if it's big files or streams. It gives us a good view of what the internet usage is of users who are coupled to an IP address. That way, if there are problems with, for example, a lot of data usage or problems with the connection, we can narrow it down to a single user or server and address the problem. It's really helpful for diagnostic data."

"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."

"The top features are ones that we're not using yet but we soon will be because we've just had broadband upgraded in Australia. We've got something called the National Broadband Network, which is forced onto you, so you have to take it when it arrives. We'll be trying the high availability out soon. We tried that with some load balancing, it didn't quite work as we expected, but I think that was more of a configuration thing rather than a product thing."

More KerioControl pros

Cons

"There could be improvements in the mathematical algorithms used for behavior analytics of traffic."

"One of the most important areas for improvement for Fortinet FortiGate is the limited resources for tests. I was limited to a few interfaces for one month, and it would be great if Fortinet could improve these features in their test versions."

"FortiLink is the interface on the firewall that allows you to extend switch management across all of your switches in the network. The problem with it is that you can't use multiple interfaces unless you set them up in a lag. Only then you can run them. So, it forces you to use a core type of switch to propagate that management out to the rest of the switches, and then it is running the case at 200. It leaves you with 18 ports on the firewall because it is also a layer-three router that could also be used as a switch, but as soon as you do that, you can't really use them. They could do a little bit more clean up in the way the stacking interface works. Some use cases and the documentation on the FortiLink checking interface are a little outdated. I can find stuff on version 5 or more, but it is hard to find information on some of the newer firmware. The biggest thing I would like to see is some improvement in the switch management feature. I would like to be able to relegate some of the ports, which are on the firewall itself, to act as a switch to take advantage of those ports. Some of these firewalls have clarity ports on them. If I can use those, it would mean that I need to buy two less switches, which saves time. I get why they don't, but I would still like to see it because it would save a little bit of space in the server rack."

"I need user-behavior analytics, to find threat scenarios from inside the organization, insider attacks. That would be very helpful for us. In addition, I would like next-generation features for small and medium businesses. These businesses require UTM, all in one product. Fortinet must include it."

"Maybe they can offer a smaller scope for a cheaper price for smaller organizations."

"Fortinet technical support is lacking, as OEM support is slightly better."

"It could use better throughput on some of the smaller boxes for the branch offices."

"Fortinet FortiGate SWG should be localised to specific regions to comply with local data privacy regulations because of the data privacy rules in the countries. In the Middle East, data organisation and KFA requirements are stringent."

More Fortinet FortiGate cons

"The tool provides just a general report. It does not provide a granular report. Hence, the tool should work on its reporting feature."

"The tool only had some memory-related problems."

"Having frequent live webinars on a monthly basis would really help."

"The solution doesn't have a web proxy built into the system like Sophos. This is something they should work to change."

"The tool needs to improve its price."

"I am not sure if this solution offers active directory integration. Adding that feature will definitely be an advantage."

"SSL VPN license cost is not cheap."

"The current usage reporting is very basic."

More Hillstone E-Series cons

"I would like to see geo-IP filtering added to the filtering rules. Incorporating these rules would be very beneficial if you have different ideas or reasons to filter, such as communication to the email server or specific websites."

"After the takeover by GFI, one of the things that Kerio built was MyKerio environment. This has not been very reliable because I get many messages that MyKerio is not functioning. For some reason, there are things that they changed and it is not very reliable at this moment, instead I have to connect to the firewall to see what is happening."

"There isn't a lot to be improved. It works well as it is, but they can maybe improve the reporting side."

"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."

"The antivirus seemed to be a bit laggy on the connection so I disconnected that. It's definitely good. The only issue we've had with any sort of cyber attack seemed to be coming from a couple of distinct locations, people trying to get into known ports on remote desktops and stuff like that. The fact that we can block all that traffic is just great. It simplifies it."

"One area that confused me a bit when I was building my current network. I use VLANs to have separate functionality on the network, and the appliance I got was the WiFi model, but I discovered that you can't assign WiFi channels to the VLAN. So, you can have WiFi, but its own subnet. You can't run that over the VLAN. Effectively, I can't use the WiFi facility in the appliance and had to purchase a separate web that supports VLANs. In the end, I had to go to GFI support. They confirmed this is just a limited functionality of that device, as it is a low-end device. I don't know if any of their high-end models have a better facility or not."

"They don't provide content filtering when it comes to search engine results. We had an incident on the network where a blocked site was showing up in search results. We are in a school environment, so we have blocked a site with some of the explicit content so that kids wouldn't see it. When one of them did a search, the results came on the search engine part. When you try to drill down to the website, it blocks, but when you search by image, it brings up all the images. That's one of the reasons why we are looking at Juniper."

"The VPN features are the ones that we really like, but we are using a VPN client to be able to use them. We would like to have an SSL implementation for this same feature so we don't need to install anything on the client side. That's a feature I really miss and that should really be embedded in the product. We really would love to use it via a web browser."

Pricing and Cost Advice

"It is affordable. Palo Alto is much more expensive than Fortinet."

"It was pretty affordable. We did go a little bit above MSRP, but the service pack that was included was quite worth the additional costs. It is competitively priced compared to other major players in the market. It is significantly cheaper than Check Point, which is a primary competitor. Additionally, its pricing is comparable to that of Cisco's ASA and a few other vendors."

"It scales well if you know what to buy from a physical box standpoint. They seem to offer something for every level."

"The value is the capability of having multiple services with one unique license, not having the limitation per user licensing schema, like other vendors."

"It is cheaper and more competitive compared to other options. For example, when comparing Palo Alto products to others, Palo Alto tends to be more expensive. If you compare Cisco's platform, including Cisco Meraki, with Fortinet products, you'll notice that Cisco's offerings are generally higher priced than Fortinet's firewall solutions."

"You need to pay a license for this solution. Our licensing is now done in our subsidiary."

"Pricing is good. They offer a lot of things, the most important is the support. Every time you upgrade your license, you also get insurance for the equipment. If you have any problem with equipment, they send in new equipment."

"The pricing is fair."

More Fortinet FortiGate pricing and cost advice

"The tool's pricing is reasonable. It depends on the model. The product's pricing is around 600 USD. You need to buy a software license to activate the features. You need to pay around 150 USD for that."

"The licensing model is very complex with many subcategories of licenses you can purchase. They could make it more simplified for customers to understand."

"Hillstone's pricing is economical and neither very high nor very low."

"The cost per year for licensing, and hardware, is approximately $850 for the basic plan."

"The yearly maintenance fee is a bit high for the Kerio Control Boxes. The end of life for the devices is kind of short. It seems like they're making you upgrade within a short period of time. They should at least allow five years, but it seems like they are changing their end of life to be shorter to generate revenue."

"We have to pay approximately EUR 175 for the product."

"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."

"The price is inexpensive."

"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?"

"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."

"It is a good fit for SMBs because of its maintainability. When you want to keep your costs low, then Kerio Control is a very good solution. It's not an expensive product that is well integrated. It has a complete set of features within it that make it a very strong product."

"It's pretty expensive in licensing costs, especially if you use the product longer than one or two years. The licensing costs are still high, which I don't think is reasonable for a product like this."

Reviews from Real Users

Here is some feedback from some of our users who are currently using the solution:

PeerSpot user Brian C., Senior Technology Specialist, VP at Unified Technology Solutions, writes "It is very comprehensive and simple. It has all the active protections. It's updated. We love that you can set how often it is updated so you can work on what is right for you. A large company with a lot of bandwidth can update the virus definitions and security definitions hourly, if they want. A smaller site that's remote, where maybe updating the definitions will eat into the bandwidth, we can schedule those more to go later at night. It's very flexible and works for us in all types of situations. This is great because then we don't have to learn seven different products to be able to work with seven different scenarios."

Andy D., IT Manager at Flare Technologies, praises how easy it is to use and says, "One thing we use quite a lot, as well, is the DHCP Server, because we do a lot of work where all our devices need to have static IP addresses. Rather than going around and configuring every box, we do it all through DHCP reservations. It's easier. We've got a record of it. We can manipulate it if we need to change something or change some hardware. It's all easy. Even guys who are not used to using it can pick it up quite quickly."
