Great security and authentication but the setup can be complex
Pros and Cons
- "The classification of the websites is helpful."
- "There is no flexibility."
What is our primary use case?
What is most valuable?
Security and authentication are the most valuable aspects of the product. The classification of the websites is helpful.
The solution is stable and reliable.
What needs improvement?
We have several access points on FortiGate, which were procured long ago. Those are not supporting the present firmware update we make on the UTM. Therefore, we cannot get the latest firmware updated on the UTMs. I was thinking that if we need to get rid of these physical devices, we should move to some cloud-based system.
The only problem that we are facing at the moment is that all the devices of FortiGate, whether it is for FortiGate's access points or authenticator or controllers or UTM, is in the FortiOS. They are interrelated and interdependent. It means if I buy a FortiGate car, I have to run FortiGate OS, I have to fill in FortiGate fuel, and I have to run it on a Fortinet road. I can’t mix and match it with different solutions. There is no flexibility.
The initial setup is a bit complex.
We would like to have NMS built into the solution.
For how long have I used the solution?
We’ve been using the solution for the last ten years.

What do I think about the stability of the solution?
The solution is stable. We’ve never had any issues with the product. It’s reliable. There are no bugs or glitches.
What do I think about the scalability of the solution?
If I need to scale it up, then again, I have to change the entire family of it.
The amount of users connected at any given point is something around 6,000, including the students and the people on move.
How are customer service and support?
We never use tech support from Fortinet. We get support from a local supplier.
Which solution did I use previously and why did I switch?
We are tied to Fortinet and therefore did not use any other product.
How was the initial setup?
Initially, the solution can be a bit complex to set up. It’s not simple. There’s a learning curve. You need to train on it a bit first.
We have ten to 12 people on hand who are specialized in FortiOS and can handle deployment and maintenance tasks. We have a total of 20 people working on maintenance.
What's my experience with pricing, setup cost, and licensing?
The pricing is pretty high. I’d rate it at a two or three out of five in terms of affordability.
Since the pandemic, a lot of things have gotten exponentially higher. Also, for us, the final price is dependent on the dollar conversion rate. You can get a license for one or up to five years.
Which other solutions did I evaluate?
Since we are tied to Fortinet and could not use anything else, we did not compare it to other solutions.
What other advice do I have?
We are customers and end-users.
I’d rate the solution seven out of ten.
I’d recommend the solution for an enterprise user. However, it may be a bit much for a small or medium-sized organization.
Which deployment model are you using for this solution?
On-premises

Reliable, low maintenance, and installation simple
Pros and Cons
- "I have found the most valuable feature of Fortinet FortiOS is the low maintenance."
- "The central management can improve in Fortinet FortiOS. It is sometimes difficult to manage all the devices."
What is our primary use case?
Fortinet FortiOS provides a full UTM experience, including UTM profiles, firewall rules, remote access, VPN connection, IPSec, and SSL connection.
What is most valuable?
I have found the most valuable feature of Fortinet FortiOS is the low maintenance.
What needs improvement?
The central management can improve in Fortinet FortiOS. It is sometimes difficult to manage all the devices.
I wrote my opinion about changes to the SSL-VPN authentication directly on the Fortinet forum, and they said that right now they will not change it. Hopefully, in the future, they will change the SSL-VPN authentication for groups and users.
For how long have I used the solution?
I have been using Fortinet FortiOS for approximately five years.
What do I think about the stability of the solution?
The stability of Fortinet FortiOS depends on the operation being done. If we are using the basic functions I would rate the stability of Fortinet FortiOS a five out of five. If we are using the advanced functionality I would rate the stability a three out of five. Overall the solution is stable.
How are customer service and support?
The support from Fortinet FortiOS is good. However, there are times they give a five out of five level of support and whereas other times they give a one out of five.
How was the initial setup?
Fortinet FortiOS's installation is easy.
What's my experience with pricing, setup cost, and licensing?
The scalability of Fortinet FortiOS is good. However, central management is intuitive for the end-users. We had a lot of questions about central management, and sometimes they didn't use it and did their firewall management directly on FortiGate instead of using Fortinet FortiOS.
What other advice do I have?
My advice to others is for them to read the instructions on how to use the solution.
I rate Fortinet FortiOS a nine out of ten.

User-friendly with a good interface and dashboard
Pros and Cons
- "We've been happy with the pricing."
- "For monitoring purposes, we don't have any option to monitor the ISP link."
What is our primary use case?
We are using the solution as a firewall. It provides portal access.
What is most valuable?
Feature-wise, the solution is strong. It has SD-WAN, site-to-site VPN, load balancing, and application-based load balancing.
It's very user-friendly.
Compared to other OEMs, due to the SD-WAN and the IPsec VPN, there is no need for the licensing for SD-WAN and the IPsec site-to-site on the remote access VPN.
Chipset wise they're using an ACS chipset dedicated to FortiOS.
The interface and dashboard are good.
We've been happy with the pricing.
The initial setup is easy.
What needs improvement?
There aren't any features missing at this time.
For monitoring purposes, we don't have any option to monitor the ISP link. If the ISP link goes down, then there is no monitoring tool or in-built monitoring tool. We can use a third-party application, like Zoho or PRTG. However, we would like something in-built.
They need to improve the solution at the application level.
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?
Sometimes it is unstable. However, they'll easily fix the issue. We get upgrades and updates. If there is even any vulnerability or malware, we'll get it fixed immediately. They give good responses to the customers.
While there are bugs, sometimes the development team is on top of it and fixes everything fast. They'll send a patch in the next update.
What do I think about the scalability of the solution?
We work with more than 100 customers.
How are customer service and support?
Technical support is helpful and responsive.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
I worked on FortiGate and Palo Alto.
How was the initial setup?
The solution is very simple, very straightforward. It's not complex a all.
How long it takes to deploy depends on the client's requirements.
For a mid-level customer, we can deploy within an hour. We can complete everything and have it up and running, and the users get internet access. If they need more rules, they need more things, then it could take time, depending on the configuration.
What's my experience with pricing, setup cost, and licensing?
The cost of the solution has been fine.
You do have to pay for a license. I'm not sure of the exact cost. I'm more of a technical person.
What other advice do I have?
We're a customer and end-user.
We have the solution deployed on the cloud and on-premises.
I've deployed the 600F model a couple of times.
New users need to do some homework, and then we proceed with the configuration. Security-wise, they need to make the customized port.
I'd rate the solution eight out of ten.
Which deployment model are you using for this solution?
Public Cloud
If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?
Amazon Web Services (AWS)

The initial setup was not very easy but the solution does integrate without much complexity.
What about the implementation team?
Our internal team of two engineers deploys the solution in about three days.
What's my experience with pricing, setup cost, and licensing?
The licensing costs are paid by our customers on a monthly basis and include maintenance and technical support provided by three of our engineers.
The solution is quite affordable and I rate the cost a four out of ten.
What other advice do I have?
The solution is a leader in security according to the Gartner Report and I recommend its use.
I rate the solution an eight out of ten.
Which deployment model are you using for this solution?

Easy to configure with an easy initial setup and good scalability
Pros and Cons
- "FortiGate as a product is very easy to configure."
- "Technical support could be better. Some competitors have much more responsive support teams."
What is most valuable?
FortiGate as a product is very easy to configure. There is a lot of data now with switching IDS and IPS. It's a truly complete solution for our customers.
It's a good idea to have the firewall connected to the switches. That way, the firewall is the controller of the switches. We like how the solution is designed with that in mind.
What needs improvement?
The solution's switches are lacking. They need more features added to them to build them out a bit. The switches are very simple if you compare them with other companies like Cisco or Aruba. Those organizations offer their clients much more.
Technical support could be better. Some competitors have much more responsive support teams.
I know the last version had NAC, network access control, added inside the firewall. It's a process, however. There's still work to do. The next version will be better. Right now, you can't authenticate other devices. You only can authenticate Forti devices and not devices from other companies. This could be the next addition to the solution that will make its performance even better.
For how long have I used the solution?
I've been dealing with the solution for ten years now. It's been a decade.
What do I think about the stability of the solution?
The solution is stable. We have no issues in that regard. There aren't bugs and glitches. It doesn't crash. It's reliable.
What do I think about the scalability of the solution?
The solution is very scalable. We have a solution from the most basic office setup to a very complex data center. It works well in either scenario. If a company requires scale, this solution can provide it.
How are customer service and technical support?
I have used technical support in the past. It's good for the most part. However, other companies, from my experience, have better technical support. They might be able to improve this aspect of the solution a little bit.
While it's easy to access them, finding a solution to whatever problems you are dealing with takes a long time. They need to get better at turning around queries faster so clients aren't kept waiting for so long.
How was the initial setup?
The initial setup is very straightforward. I wouldn't describe the process as complex.
Deployment takes one to two hours. Everything happens pretty fast.
What's my experience with pricing, setup cost, and licensing?
The pricing is good. They are especially fair when compared with other companies, like Palo Alto, for example, which can get quite expensive.
What other advice do I have?
We work with a lot of manufacturers of firewalls. It's normally Fortinet, however, we also work with Cisco, Palo Alto, and Sophos. My company works with Barracuda as well. To be honest, I am not a specialist with Barracuda. I normally don't work with that.
That said, typically, when we work with clients, one of the first solutions we will suggest will be Fortinet. We do normally also recommend Cisco first, as well, due to the fact we are Cisco partners. We're also partners with Fortinet.
We have a deal with Palo Alto and our security center recommends Barracuda because of their other security solutions like WAF or solutions in the cloud (not their firewall).
Normally, we use the on-premise deployment model. At this moment, we are working with a public cloud deployment model as well.
I'd rate the solution eight out of ten overall.

Has intuitive policy creation and deployment and precise parameter settings to determine thresholds
Pros and Cons
- "Fortinet FortiOS's valuable features include intuitive policy creation and deployment, precise parameter settings to determine thresholds, and security profiles such as web filtering and remote application filtering, among others."
- "Fortinet FortiOS's integration could be improved."
What is our primary use case?
We use the solution for automated solutions.
What is most valuable?
Fortinet FortiOS's valuable features include intuitive policy creation and deployment, precise parameter settings to determine thresholds, and security profiles such as web filtering and remote application filtering, among others. These features greatly enhance the platform. It includes every available application in terms of features. For example, in RDP, we must control the application. It’s already there whenever we want to apply their role or policy to that application.
What needs improvement?
Fortinet FortiOS's integration could be improved. It has extensive integration features, such as collectors for other services and third-party intelligence feeds.
For how long have I used the solution?
I have been using Fortinet FortiOS for six months. We are using the latest version of the solution.
What do I think about the stability of the solution?
The product is stable.
What do I think about the scalability of the solution?
The solution is scalable. We have around 300 users using this solution.
How are customer service and support?
We initiated support from our servers because the other part of the company was not working. They helped us adjust the tuning, and it is working now.
How was the initial setup?
The initial setup is not complex. It will take around two or three days to deploy. Product cleaning, readjustment, and screening are continuous tasks, as the nature of the work requires tuning and adjustments. To connect the PC to the console, we assign the networking settings, including data capabilities, and then reconfigure them on the web interface (UI). Some settings are also presented in a web-based format in the CLI because they are easier to navigate.
What other advice do I have?
The reserve utilization is very low. Based on my learning, my expectation is for every product to have a good intelligence system and frequently updated threat intelligence. Overall, I rate the solution a nine out of ten.

We are using it for security purposes.
What is most valuable?
The security on offer is good.
It's quite stable.
The scalability has been great.
We found the initial setup to be straightforward.
Technical support has been good overall.
What needs improvement?
The UI could be a bit better. The coming generation will not be from the Sierra, and therefore they have a chance to make it much better and more user-friendly. Right now, we have to contend with CLI. We'd like it to be easier. We need the features to be in a UI.
For how long have I used the solution?
I've been using the solution for more than five years.

We have more than 5,000 people on the solution right now.
How are customer service and support?
Technical support has been good in general. They are helpful and responsive. I have no complaints in regard to their level of service.
How would you rate customer service and support?
Positive
How was the initial setup?
It offers a pretty simple and straightforward setup. I'd rate it four out of five in terms of ease of implementation. It's not something that's too complex or difficult.
What's my experience with pricing, setup cost, and licensing?
I don't have many details surrounding the licensing. It's not an aspect I directly deal with. My understanding is the solution is moderately priced.
What other advice do I have?
We are Fortinet partners.
If a company is looking for a local security enhancement, we tend to recommend or select this kind of solution.
I'd rate the product nine out of ten overall.

A seamless endpoint gateway solution with constant updates and a zero choice engine
Pros and Cons
- "The most valuable features of Fortinet FortiOS are its constant updates and definitions."
- "I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle."
What is our primary use case?
We use it for end-point gateway protection and also use the FortiOS for external user connection and server VPN. We love that clear synchronization as it's almost invisible with the fabric for the guests, externally to connect. The zero-choice engine that they use is pretty good. It is perfect for setting up one-to-one channels for different services that have to pass through the firewall. So it does that seamlessly.
What is most valuable?
The most valuable features of Fortinet FortiOS are its constant updates and definitions. The new definitions and the content information coming out to the threat labs keeps you updated on your signatures so that you know what's happening out there. And also doing well, for my system, we have, like, what is called, active scans.
It's constantly accessing Sophos into your gateway, even Sophos that you authorized.
What needs improvement?
I want to see a better integration or a better integration with the endpoint protection or with EDR with the security life cycle. I want to see if that enhances a bit more so I have granular datasets and the user level through to the gateway because that's where most of our threats come from. It's from user activities on the Internet and passes into your files over that gateway. That's where most of our threats would appear and where our exposure to vulnerabilities lies.
So if we can tighten that up, we can harden our infrastructure much better.
For how long have I used the solution?
I have been using the solution for quite some time.
How are customer service and support?
The customer support team is good and responsive.
How was the initial setup?
We did the initial setup ourselves, so it was easy. The learning curve was that great once you have any experience with any firewall or any experience with any security appliance, you can pull around it. We did get some help from our providers. But that was basic.
What about the implementation team?
The EMS setup was all in-house. Our service provider assisted with the firewall setup. The implementations were very smooth. And the transition of our current from our current security device to that when we did it a couple of years ago, it's seamless.
What's my experience with pricing, setup cost, and licensing?
The pricing is competitive for the medium and high markets but for the small markets it can be expensive.
What other advice do I have?
You have to see what works best for your environment. Each environment is different depending on the applications and different services you are running in that environment. Suppose it's a full Windows environment versus a mixture if you have a hybrid environment. It all depends on the type of environment you're running and finding the right tools that meet your domain.
But for the regular Windows environment, it's perfect.
I rate it eight out of ten.
