Next-generation firewall that can detect threats other solutions do not
Pros and Cons
- "FortiOS's most valuable feature is a next-generation firewall that can be used as the APT solution in advanced threat protection."
- "The threat time interval lags a little, especially if there's a heavy load on the firewall."
What is most valuable?
FortiOS's most valuable feature is a next-generation firewall that can be used as the APT solution in advanced threat protection. The IPS feature is also very good and can sometimes detect threats that are not detectable by the Palo Alto firewall.
What needs improvement?
The threat time interval lags a little, especially if there's a heavy load on the firewall.
For how long have I used the solution?
I've been working with FortiOS for over four years.
What do I think about the stability of the solution?
FortiOS is one of the most stable solutions.
What do I think about the scalability of the solution?
FortiOS is very easy to scale.
How are customer service and support?
Fortinet's technical support is good.
How was the initial setup?
The initial setup was easy and could be done without an integrator or other external assistance.
What other advice do I have?
Compared to other firewalls like Palo Alto, FortiOS is easy to deploy and upgrade - for example, an upgrade of Palo Alto takes at least thirty minutes, but Fortigate can be done in around ten. I would rate FortiOS eight out of ten.

IT Consultant at a tech services company with 51-200 employees
Cost-effective solution for medium-sized businesses and mid-range corporations but it has some product limitations
Pros and Cons
- "A good network security system for medium-sized businesses with an excellent GUI interface that gives a graphic view of network status."
- "While it is a solid solution, there are some product limitations which exclude it from deployment in some situations."
What is our primary use case?
Our primary use case for this solution is for deploying network security systems for SMBs or mid-range corporations.
How has it helped my organization?
We use the SSL VPN web portal and we actually find it very useful because we don't need to bother with installing additional client-side software.
What is most valuable?
The most valuable part of the application is the graphic user interface of the application where you can see specifically what's going on in the system at a glance and quickly assess the system. The GUI is very good.
What needs improvement?
One thing that should be improved in future versions is an issue we have observed and had problems with a few times. When we try to reinstall a backup for FortiOS, you need to do a factory reset manually or you lose access to a device. I have experienced this situation a few times and it seems like something that should not be required and they should resolve.
For how long have I used the solution?
We have been using the product for about five years.
What do I think about the stability of the solution?
I think the product is a pretty stable solution. I did have some cases with the webserver where the appliance actually crashed. Later I research about the issue and I found out that it was actually a bug in the latest version. I imagine that because they know they will issue a fix if they have not already.
What do I think about the scalability of the solution?
I recommend this product to my clients partly because of the scalability. Scaling is never really a problem though it may cost more if the client requires additional licensing or hardware.
How are customer service and technical support?
I don't often have to contact support. When I do I usually just get help from the online community. I really don't contact their support directly.
How was the initial setup?
I go about initial setup by just implementing the configuration using CLI (Command Line Interface) to propagate the components. I think the initial setup is straightforward.
What about the implementation team?
We are the consultants and we do the installations.
What's my experience with pricing, setup cost, and licensing?
I think the cost of the product categorizes FortiOS because it is a bit more expensive than small businesses will usually want to spend. It is not really practical for SMB or for small businesses. It is mostly for mid-range or higher SMBs because of the pricing. It is not expensive compared to some products, but a small business may not justify the cost. The cost ends up being dependent on the solution you choose and if you want individual or package licensing.
Which other solutions did I evaluate?
As consultants, we provide different customers with different solutions based on what they need. So, there is no specific product that we evaluate as there are always several options. Mainly I use Fortinet or Sophos solutions to recommend to my customers. We will use on-premises or cloud depending on the needs and how it fits for the client. For Fortinet FortiOS we usually use it in on-premises installations.
What other advice do I have?
I do recommend this product to clients for use but it depends on their case needs. For example, in the AAA (Authentication Authorization and Accounting) some of the accounting and some of the VPN tunneling features are removed from Fortinet FortiOS due to some security configurations. In some projects, we need those features for the client and when that is the case, I cannot recommend that the client use the FortiOS solution.
It would be a better product if there were a logging feature. You need to have FortiAnalyzer in your installation to have logging management capabilities. It will be a better solution if some logging and history capabilities were integrated without requiring an additional product installation.
On a scale from one to ten, where one is the worst and 10 is the best, I would rate Fortinet FortiOS a seven. It is a good product but there are a few problems.

Senior Presale Manager at a tech services company with self employed
A feature-rich and stable solution, but the GUI needs to be improved
Pros and Cons
- "All of the features in this solution are effective and efficient."
- "The GUI could be improved to make it more usable, easier to administer, and easier to configure."
What is our primary use case?
I am a consultant, and I have worked with solutions from many different vendors. Depending on what the customer wants, we help to select the solution. This is one of the solutions that I have serviced in a client environment.
What is most valuable?
All of the features in this solution are effective and efficient. They are dependent on the environment in the organization.
What needs improvement?
The policies and the way that they are applied can be improved. It could be more direct, as it is an issue for some people. Generally, policy management could be made better and simpler to deploy.
The GUI could be improved to make it more usable, easier to administer, and easier to configure.
For how long have I used the solution?
I have been working with this product for several months.
What do I think about the stability of the solution?
I think it's a stable solution.
What do I think about the scalability of the solution?
We have been deploying this solution in small and medium-sized environments, with no more than fifty users, and it has always been effective.
How are customer service and technical support?
I don't think that we have had any issues with technical support for this solution.
How was the initial setup?
The difficulty of the initial setup depends on who is handling it. Definitely, there are challenges, but if you have a proper understanding of what you're supposed to do, then it is straightforward to work with.
For me, I think that the physical box is more straightforward to work with, but it depends on who is doing it. If you get your architecture right then it is a pretty straightforward deployment. If you don't, then you run into issues that you will need to troubleshoot.
What other advice do I have?
For my requirements and expectations, I would rate this solution a seven out of ten.

User-friendly interface, high performance, and low maintenance
Pros and Cons
- "The most valuable features of Fortinet FortiOS are the ease of use and user-friendly interface."
- "Some features I have found to be hidden and cannot be accessed through the graphical user interface, you can only access them through the command-line interface(CLI). All the features should be accessible through the graphical user interface."
What is most valuable?
The most valuable features of Fortinet FortiOS are the ease of use and user-friendly interface.
What needs improvement?
Some features I have found to be hidden and cannot be accessed through the graphical user interface, you can only access them through the command-line interface(CLI). All the features should be accessible through the graphical user interface.

I have been using Fortinet FortiOS for approximately four years.
What do I think about the stability of the solution?
Fortinet FortiOS is a stable solution and it has high performance.
What do I think about the scalability of the solution?
The scalability depends on the cloud provider of Fortinet FortiOS, such as Amazon AWS or Microsoft Azure. They need to work according to their SLA.
How was the initial setup?
The deployment of Fortinet FortiOS is simple. The speed of the deployment depends on a lot of factors, such as a number of policies, features we need to enable, and security specifications.
What about the implementation team?
I do the deployment of Fortinet FortiOS and since it is on the cloud there is no maintenance.
What's my experience with pricing, setup cost, and licensing?
The price of Fortinet FortiOS is reasonable and it is paid annually. You are able to select the features that you want.
What other advice do I have?

It has high availability features so we can have one box on hot standby to take over when another one crashes
Pros and Cons
- "FortiOS allows us to set up alarms for blocked websites and SSL verifications. When someone tries to access a blocked site, the solution sends a notification to the IT manager's mailbox."
- "FortiOS could provide a more detailed analysis of the network and connected devices."
What is our primary use case?
I was working at a bank where internal information security was strict, so I needed to block a lot of websites in Fortinet. For example, we needed to block Gmail, WhatsApp Web, porn, and violent content.
What is most valuable?
FortiOS allows us to set up alarms for blocked websites and SSL verifications. When someone tries to access a blocked site, the solution sends a notification to the IT manager's mailbox.
The user interface is easy to use. Fortinet has high availability features, so you can have an active and hot standby box. We can have two boxes in Rio and two in São Paulo. When a box crashes, we can transfer all the operations to the second box.
FortiOS tells you exactly what is happening in the first box, so you can quickly understand what went wrong and troubleshoot. Users rarely notice an impact on the daily operations.
What needs improvement?
FortiOS could provide a more detailed analysis of the network and connected devices.
For how long have I used the solution?
I used Fortinet for about nine months.
How are customer service and support?
We have a support contract with a third-party company, but Fortinet provides the licenses, so we update the solution ourselves using the license code.
What other advice do I have?
I rate Fortinet FortiOS nine out of 10.
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.
