Manager - IT Business Solutions at Kuwait Automotive Imports Company
Easy to set up, reliable, and good for traffic management
Pros and Cons
- "It's simple to use in terms of inbound and outbound traffic management."
- "I would like to see more statistics in the monitoring part."
What is our primary use case?
We use the solution as a perimeter firewall.
What is most valuable?
It's simple to use in terms of inbound and outbound traffic management, traffic shaping, and connectivities, as well as the VPN. Everything is built into it, so it gives us quite a good well-rounded solution.
With assistance, the initial setup is easy.
The solution is stable and reliable.
What needs improvement?
I would like to see more statistics in the monitoring part. There is monitoring, there are DSCPs, and everything; however, I would like to have more active monitoring of the traffic.
Sometimes we would like to monitor some threats. For example, where are some bots, and how do we detect these kinds of things. That would be good for us.
For how long have I used the solution?
I've been using the solution for more than five years.
What do I think about the stability of the solution?
We've been happy with the stability. It's been good so far. There are no bugs or glitches. It doesn't crash.
What do I think about the scalability of the solution?
We are not scaling it right now. We bought it sometime back and we didn't need to scale it. We bought a higher end for our use case, which is still sufficient for another few years.
We have 200 or so users of different levels and positions on it.
We do not have plans to increase usage.
This firewall is quite a capable firewall - even up to 1000 users. Due to that, we didn't find any requirement to expand it or replace it somehow. It has helped us build our software-defined WAN, LAN, et cetera. It is sufficient for us. It gives us Gbps throughput, which is good enough. The firewall itself is 32Gbps capable, which is more than what we need.
How are customer service and support?
We have used support sometimes. That said, mostly we use it via the third party directly. They are helping us with support of any type that we need.
Which solution did I use previously and why did I switch?
There was something else that was used. However, I don't remember what was that previously.
How was the initial setup?
The initial setup was easy for us as we had assistance.
For the deployment, one person was involved from the outside, and two people we assisting from our side. In total, three people were involved.
The deployment itself took a few days as we were rebuilding policies as well.
What about the implementation team?
The initial setup was done by the contractor. For that reason, we had no problem implementing this.
What was our ROI?
The ROI we have witnessed is good. I would rate it five out of five.
What's my experience with pricing, setup cost, and licensing?
We started with a three-year license and have since renewed it.
For three years, we paid about 2,800 KD, which is about $9,000.
The product is pretty affordable overall.
What other advice do I have?
We are just customers of the solution.
We're not using the most recent version. We updated it a few years ago and we are still using that version.
I'd rate the solution ten out of ten. We are really happy with it in general.
Potential users should plan what they want to do with it before buying something this big and this good. They should know what they want to do first and then act accordingly.
Which deployment model are you using for this solution?

Senior Network Administrator at Tawasul telecom
Easy to set up with good segmentation but need better support
Pros and Cons
- "Compared to other firewalls, the segmentation is much easier in FortiGate."
- "Their first-level support is often poorly trained."
What is our primary use case?
We're using the solution for firewall segmentation, including segmentation of the network, authentication purposes, logins, et cetera.
What is most valuable?
Compared to other firewalls, segmentation is much easier in FortiGate.
The initial setup is straightforward.
What needs improvement?
The support could be better. Their first-level support is often poorly trained.
We don't have any other requirements in terms of needing new features.
For how long have I used the solution?
I've used the solution for ten years.
What do I think about the stability of the solution?
The solution is stable. There are no bugs or glitches. It doesn't crash or freeze.
What do I think about the scalability of the solution?
It's scalable. The model we bought is highly scalable. However, if you buy a device on the low end, it may not be scalable. You need to consider what you need in advance and buy more than you need if you believe you will need to scale.
How are customer service and support?
Technical support is okay. Compared to Palo Alto, they need to improve a bit. Palo Alto is better. The first-level team isn't very knowledgeable.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I work with Palo Alto, Cisco, Fortinet, et cetera.
How was the initial setup?
The initial setup is very simple and straightforward. It's not overly complex or difficult. You only need one person to implement the solution.
The deployment will take only one hour, however, the policy web creation based on the user requirements may take time. That is the nature of every firewall. Usually, the deployment takes only one to two hours.
What about the implementation team?
We handled the setup in-house. We didn't need any outside assistance.
What's my experience with pricing, setup cost, and licensing?
I don't directly deal with licensing. I can't speak to the exact costs.
What other advice do I have?
I'm an end-user. I used to be a partner.
We're using the latest version of the solution and update regularly.
I'd rate the solution seven out of ten.
Which deployment model are you using for this solution?
On-premises
Disclosure: I am a real user, and this review is based on my own experience and opinions.
President at Key Solutions, Inc.
Also offers email filtering and data loss prevention
Pros and Cons
- "All networks are security-driven, we get throughputs and security. We feel that the people at Fortinet are easy to deal with from a support standpoint. If they need to jump in and help us, they're very willing to do that. Their email filtering, their data loss prevention, their intrusion prevention, type of products in the newest OSs has been outstanding."
- "It could more scalable for the lower end users."
What is our primary use case?
It's a security device. We use it to keep the bad guys away.
What is most valuable?
A firewall is a security appliance. FortiGate also does email filtering and does data loss prevention.
All networks are security-driven, we get throughputs and security. We feel that the people at Fortinet are easy to deal with from a support standpoint. If they need to jump in and help us, they're very willing to do that. Their email filtering, their data loss prevention, their intrusion prevention, type of products in the newest OSs has been outstanding.
For how long have I used the solution?
I have been using Fortinet FortiOS for ten years.
What do I think about the stability of the solution?
The stability is excellent.
What do I think about the scalability of the solution?
Scalability is wonderful. Affordability is really good.
Everybody's being protected by the firewall. The firewall device is using the operating system. And so, in that sense, you could say everybody is using it. The people that are actually technically working with the Fortinet devices are a handful, six to eight technicians.
How are customer service and technical support?
We feel that the people at Fortinet are easy to deal with from a support standpoint. If they need to jump in and help us, they're very willing to do that. Their email filtering, their data loss prevention, their intrusion prevention, type of products in the newest OSs has been outstanding.
Which solution did I use previously and why did I switch?
We've used other solutions in the past. But we've settled into FortiGate for around 10 years.
How was the initial setup?
The initial setup was straightforward. It's pretty much just plug and play. It takes hours.
What's my experience with pricing, setup cost, and licensing?
They're very competitive and easy to work with in terms of pricing. I can't say, that's why we chose them, that's why we've stuck with them. It's a very well-respected name in the industry.
Everybody wants to go to Cisco for different things and everybody loves to hate Cisco. Cisco is a great product for large companies. They're low income, they're low-end products and their support for their low-end products leaves a lot to be desired. That's hence why SonicWall, Extreme Networks, and Fortinet are in business. There are these other smaller companies that are getting involved with the smaller companies, taking market shares away from Cisco because Cisco's support for their product is bad.
The support contracts are usually about $100 - $200 a device. The support contract usually includes software upgrades, hardware maintenance, and hardware break-fix. And they very seldom break.
Which other solutions did I evaluate?
I am looking at replacing some SonicWalls for a customer. I think SonicWall is its competition. SonicWall is got a good product, but I still believe that FortiGate is the best product for the people that we deal with.
What other advice do I have?
My advice to someone implementing this solution is not to take shortcuts. Shortcuts aren't good. Don't hesitate to use FortiGate's technical support.
Always buy support. Always buy FortiCare. You can buy it for one year, two years, or three years with the initial purchase. We always buy it and sell it to our customers for three years. And the product will last more than three years.
Fortinet competes in the big companies as well. We just don't. Our marketplace is the smaller users two or three, maybe four locations, 150 to 300 endpoints. So we're not dealing in the 10,000s of users trying to get into 100 of servers. We're dealing with tens and fifties and a hundred, trying to get into a few servers.
I would rate it a nine out of ten. It could more scalable for the lower end users.
Which deployment model are you using for this solution?
On-premises

Data Analyst at a wholesaler/distributor with 51-200 employees
Protects our web servers from XSS and SQL Injection attacks at competitive pricing
Pros and Cons
- "The firewall options in FortiOS allow us to open up access to our vendors for EDI and all its features."
- "Fortinet could integrate something like a YubiKey for 2FA with their SSL VPN clients."
What is our primary use case?
I used FortiOS, the Fortinet firewall operating system, to connect two additional sites. I set up IPSec VPNs to connect all three sites. I also configured firewall rules to block certain countries and websites, such as gambling and social media sites like Facebook. Additionally, I implemented firewall rules to protect our web servers from XSS and SQL Injection attacks. Initially, I configured the VPN using IPsec, but when I couldn't find a suitable client for our workstations and desktops, I switched to SSL VPN. Fortinet provides dedicated FortiClient VPN software, which I used for this setup.
How has it helped my organization?
At the beginning of this month, we experienced DDoS and SQL injection attacks. The attack originated from a botnet and seemed to be associated with BroadNet. It was coming from a Fortinet device. I had to contact Spectrum to inform them about the botnet attack and provide them with the specific IP addresses to block. This action likely prevented us from being hacked and protected our web servers that were exposed to the public. This incident highlighted the usefulness of FortiOS's threat intelligence features.
What is most valuable?
The firewall options in FortiOS allow us to open up access to our vendors for EDI and all its features.
What needs improvement?
Fortinet could integrate something like a YubiKey for 2FA with their SSL VPN clients. Additionally, Fortinet could support WireGuard for our small office locations.
These small offices have two clients that log into our VPN from their workstations. Since all our sites use FortiGate, it would be great if I could set up WireGuard on the Fortinet device. Instead of using IPSec, having WireGuard support for site-to-site VPNs would be wonderful.
For how long have I used the solution?
I have been using Fortinet FortiOS since February this year.
How are customer service and support?
They handle the support because it's their device. We don't own it; we lease it from Spectrum. So, I can't speak to that for now. However, when we used to own the FortiGate, every time I called Fortinet for support, I would rate their response time at eight out of ten and their problem-solving ability at nine out of ten.
Once they respond, because it takes me a while to navigate the bureaucracy, I call the 800 number. They ask for various information, tokens, and other details. After I explain the problem, they call me back again. Usually, they assign the issue to an engineer, which also takes time. The engineer then calls me and solves the problem. So, I have to deal with a lot of bureaucracy.
How would you rate customer service and support?
Positive
What was our ROI?
We had a really old FortiGate there, and when we switched to the newer FortiGate, it was cheaper than the old one.
What's my experience with pricing, setup cost, and licensing?
When we purchase a FortiGate, it comes with FortiOS. Overall, the pricing for the device and related components is better than average. In comparison, FortiGate offers more competitive pricing than Palo Alto and Cisco.
What other advice do I have?
If they could log in, it would be possible only if FortiOS is included. With FortiOS, you can manage all your devices. Let's say you have ten devices and need to manage all of them, including patching FortiOS. FortiCloud helps you with that, and it's nice to have FortiCloud as a bundle with FortiOS. Even if you only have one device, I would still recommend it.
I suggest incorporating AI or machine learning to anticipate threats in the future. For instance, if you configure a new site with your FortiGate, AI could detect any misconfigurations. It would be beneficial for FortiOS, FortiGate, or Fortinet to have an AI feature that alerts you to potential misconfigurations in devices, like an edge router, communicating with others. This AI could also analyze your logs to identify patterns, such as frequent false positives, and recommend reconfiguring the device to minimize unnecessary alerts.
It's good. In my case, I was the only one dealing with the devices at that time. I would get all kinds of false positives and alerts. Sometimes, if there's a new device, the configuration from the old device to the new device doesn't translate. Maybe on the old device, everything defaults to open, and you must close everything. On the new device, everything might be defaulted to closed, and you have to open up the required ports. So, something like that would be nice, where it's easier to configure and find out if you did something wrong.
Overall, I rate the solution an eight-point five to nine out of ten.

A next-generation operating system and firewall with a lot of features
Pros and Cons
- "I am satisfied with Fortinet FortiOS. It's a cool product and has a lot of UTM features. It has application control, web filtering, antivirus, IPS/IDS, DNS filtering, and many things in that firewall. It also has a web application firewall WAF feature. On the feature side, it's a good firewall."
- "It would be better if AWS instances were available. If I want to upgrade from T2.small to T2.medium, it should be available rather than having a big instance and paying a lot of money for that. The issue is that we had deployed in AWS Cloud, and we were using a very small instance. Recently we wanted to move in-house and deploy it on the big instance because it was struggling with the RAM. If we use T2.small, we cannot upgrade it to the T2.medium. It has predefined instances in the marketplace with a lot of cost differences. If I can increase the RAM, I have to choose the T3.large instance. If I'm paying $270 for the small instance, I have to pay more than double the cost for T3.large. It is about $850, and this is not good. So, it would be better if it was cheaper. I think both AWS and Fortinet should think about that. They should provide it on lower instances as well. If I want to upgrade it from T2.small to T2.medium, it should be available, but it's a problem."
What is our primary use case?
We use Fortinet FortiOS to protect our office, and we have another deployment in production. We have the PCI DSS environment on which we have deployed the Fortinet Firewall.
What is most valuable?
I am satisfied with Fortinet FortiOS. It's a cool product and has a lot of UTM features. It has application control, web filtering, antivirus, IPS/IDS, DNS filtering, and many things in that firewall. It also has a web application firewall WAF feature. On the feature side, it's a good firewall.

I think both AWS and Fortinet should think about that. They should provide it on lower instances as well. If I want to upgrade it from T2.small to T2.medium, it should be available, but it's a problem.
For how long have I used the solution?
I have been using Fortinet FortiOS since 2019, so more than three years.
What do I think about the stability of the solution?
Fortinet FortiOS is a stable product.
What do I think about the scalability of the solution?
Fortinet FortiOS is scalable.
How are customer service and support?
Technical support is good. When I create the ticket, they respond to me, engage the engineer, and support is good. No issue at all.
How was the initial setup?
The initial setup is not too complex; it's simple.
What's my experience with pricing, setup cost, and licensing?
It would be better if it were cheaper. We have the firewall in our office, and the license is expiring in 20 to 25 days. We got a quote for almost 80,000 Pakistani Rupees, which is a little costly.
Which other solutions did I evaluate?
If I compare Fortinet FortiOS with Cisco Adaptive Security Appliance (ASA), it's a cool product. The deployment of ASA is a little bit complex because it's GUI-based, and ASA also has a graphical user interface. But I still think Fortinet is a good firewall compared to ASA because if you want to use the IPS/IDS feature in the ASA, you have to deploy the management center and integrate it with the firewall, which is a little complex.
What other advice do I have?
I recommend this solution to potential users because it has many features, and it's a stable product.
On a scale from one to ten, I would give Fortinet FortiOS an eight.
Which deployment model are you using for this solution?
Hybrid Cloud

Head of Infrastructure Network at innovectives
Excellent integration with an open API and a very easy to use interface
Pros and Cons
- "The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly."
- "The solution is good, but they have poor marketing in Nigeria. They need to market their product better."
What is our primary use case?
We primarily use the solution for banks, whereby they want to secure their edge network, to filter their web application and block forms, etc. We also are able to integrate AWS using secure channels. It's more robust and they have different modes including nap, flow, and proximity.
What is most valuable?
You can apply patterns to look for. That can be done for applications also. You can ask for a specific feature to become a pattern. If you were using Office 360 and had 2 ISPs, automatically using SD-WAN will allow you to switch over to the other link based on the criteria you can set yourself. You don't need to go to the device to manually sort and link it, it does it automatically.
Users can go directly to the cloud from the branch instead of routing to the head office and then the cloud. That will reduce the cost of routing, so you just pay for internet service and you have access to the cloud.
The interface is easy to understand, so when there are threats you get alerts. It's quite intuitive, but if you are ever confused they have instructional videos. For example, if you don't understand a graph there's a link to a video that explains what the graph means. It makes it very user-friendly.
What needs improvement?
The solution is good, but they have poor marketing in Nigeria. They need to market their product better.
They need to work on their support. Cisco has the best technical support. In comparison, Fortinet's support takes too long. If you are paying for SLAs, you should also get value from your SLAs.
Right now, everybody is moving to the cloud. The solution has already worked on that aspect, and they are embedding security to the cloud. However, security can be more enhanced and as long as they continue to offer more protection I'll be happy.
For how long have I used the solution?
I've been using the solution for five years.
What do I think about the stability of the solution?
The solution is very stable.
What do I think about the scalability of the solution?
The solution is very scalable. It allows for API integrations so you can actually integrate into other security solutions.
How are customer service and technical support?
Technical support could be more qualified and offer a quicker turnaround.
How was the initial setup?
The initial setup is very straightforward, especially if that person understands security.
Which other solutions did I evaluate?
We integrate solutions on the client's request. Most times I push on Fortinet, as it's a robust system.
You can integrate your endpoint with Fortinet. You can integrate the cloud on-premises. Because the solution is so robust and offers excellent the features we tend to enjoy using FortiOS. Cisco is similar, however, and we do work with them too.
What other advice do I have?
We are using the on-premises deployment model.
We are an integrator, so we do integrations using Fortinet, Cisco, Sophos, and Palo Alto.
If you're an SMB or a small enterprise, I would recommend Fortinet.
I would advise users to make sure they are getting value for what they are paying for. I can say that Fortinet is not as expensive as the others, but it also gives good value. The main thing is not about the cost, but the value and Fortinet delivers on that front.
I would rate the solution nine out of ten.

General Manager & Head Electronic Network Executive at Blue Dart
Beneficial IPS, excellent support, and scales well
Pros and Cons
- "The most important feature of Fortinet FortiOS is the IPS."
- "Fortinet FortiOS need to manage its memory and CPU utilization better. It peaks at times, which sometimes can be challenging."
What is most valuable?
The most important feature of Fortinet FortiOS is the IPS.
What needs improvement?
Fortinet FortiOS need to manage its memory and CPU utilization better. It peaks at times, which sometimes can be challenging.
In a feature release, if Fortinet FortiOS could have better cloud functionality would be a benefit.
For how long have I used the solution?
I have been using Fortinet FortiOS for approximately seven years.
What do I think about the stability of the solution?
The stability of Fortinet FortiOS is good.
What do I think about the scalability of the solution?
Fortinet FortiOS is scalable.
How are customer service and support?
I rate the support from Fortinet FortiOS a five out of five.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup of Fortinet FortiOS is simple.
Which other solutions did I evaluate?
We evaluated Checkpoint and Cisco before choosing Fortinet FortiOS.
The manageability suit is better in Fortinet in terms of device manageability and OS upgrades. It has the capability of terminating a leased line, RF, and a USB dongle. When we evaluated Fortinet FortiOS, back in 2015, Cisco and Checkpoint did not have a 4G termination feature. Today if my MPLS goes down, the lease line goes down, I can connect a 4G dongle. In Cisco, you need to have a SIM embedded in a device and you need to open the device, put it on, and then you need to connect it and extend the cable. It is very complex. In Fortinet it is easy.
What other advice do I have?
I rate Fortinet FortiOS a nine out of ten.
Which deployment model are you using for this solution?
On-premises
