The solution is really important to ensure double authentication for the user. For example, if you have an internal messenger and you want to ensure the access externally for users, you can implement the two-factor authentication. Also, for the VPN, you can implement two-factor authentication to avoid any kind of hacks.
Scaling Engineer at Lutessa 2S
Ensures double authentication for the user
Pros and Cons
- "The initial setup is so easy and there is no problem in the implementation."
- "If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things. So transfer of data and other information should be simpler."

What needs improvement?
If you want some other FortiAuthenticator from one site to another site, you should have requirements, but really if you have authentication and directory or another solution, you should change the password of the authenticator between the solution and the directory and other things. So the transfer of data and other information should be simpler.
In the future, I think h02.exe is very important to authenticate users internally. To economically move the person from vnom to vnom. Also, the ESO to ensure the authentication of users should be a bit more automated.
For how long have I used the solution?
I've been using the solution for one year.
What do I think about the stability of the solution?
In my opinion and my experience, I didn't have any problem with the solution, just the requirements for other solutions that we should integrate with it. I think the solution is easily implemented, and, in my opinion, there is no problem with this solution. Just a bit of correction is needed, and that's it.

What do I think about the scalability of the solution?
My impression is that the solution is good and I like it and I would work with it for another project and increase my skill on the solution.
How are customer service and support?
I have worked with them, so I like the technical support of Fortinet. I would give them a good mark.
How was the initial setup?
The initial setup is so easy and there is no problem in the implementation. We can implement it easily in a different kind of infrastructure.
What other advice do I have?
I started working on FortiAuthenticator from last year. I have had a chance to deploy many, many projects on FortiAuthenticator. I deploy 10 next-gen projects on FortiAuthenticator. I deploy many defensive scenarios. Also, I have good experience with large products.
You should make sure to implement the requirements via experts like me, so you can implement the product carefully. In that way, you can use it clearly in a simplified manner.
For FortiAuthentication, it's a good price in comparison to any other competitor. Other products are so expensive, and the features are the same. There might be a bit of difference between the two products, but if you want just double authentication and some other features, I think I recommend the FortiAuthenticator, and it is low cost and has other defenses.
In my opinion, I recommend the solution. You can also use it for other things like h02.exe for authentication of users. Also for ESO. There are five things you can use it for, so I recommend the product. The low cost is very important for any customer.
I would rate this solution eight out of 10.

Affordable solution with a friendly UI
Pros and Cons
- "The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read English you can find your way around the solution and make it work. This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward. The UI is quite simple."
- "We would like to see Linux-based operating systems be able to integrate with FortiAuthenticator to get two-factor authentication running on them. as well. This is a shortcoming that I have faced a few times already."
What is our primary use case?
Fortinet FortiAuthenticator is being used in our clients' companies. These companies are medium to enterprise level.
What is most valuable?
The feature that I have found most valuable is the fact that you can utilize your tokens across the whole Fortinet fabric once you have the FortiAuthenticator. You can use FortiAuthenticator to provide two-factor authentication among all your network devices as long as they support the RADIUS protocol. Even for servers, especially Windows OS-based servers.
If you have any products that support RADIUS, you will be able to use the two-factor authentication. You can integrate them with the FortiAuthenticator and you can make use of the 2FA token among all our network devices, not just the Fortinet ones.
What needs improvement?
So far there hasn't been any major feature that we wished for and didn't find, but I would say in regards to bugs, sometimes we face unexpected issues that delay the implementation a little. However, I believe Fortinet will sort this out soon. Hopefully the solution will be more stable overall.
In terms of what additional features we would like to see in the next release, we would to see support for more of the common operating systems. They already support Windows OS, with the use of an agent installed on the windows machine.
However, we would like to see support for Linux-based operating systems for example. This is a shortcoming that I have faced a few times already.
Also a nice addition would be agents for End-user Machines especially Windows OS & MAC OS.
For how long have I used the solution?
We've done quite few deployments of Fortinet FortiAuthenticator over the last one and a half years.
How are customer service and technical support?
Some bugs that we find we can work around, but usually we open the ticket with Fortinet anyway. This is because sometimes we suspect that we do not have the proper understanding or maybe there is something that we need to get an insight on from the technical support because they have their big databases and can provide us with additional valuable information about our cases. Sometimes we may find a workaround, but if we don't know what happened and why, we open a case anyway to get the full details.
Fortinet support is quite good. Their engineers are experienced and well-trained. Generally speaking, we feel that the technical support is capable and know what they're doing. You don't feel that you're speaking to someone who doesn't understand what the product is, which we face sometimes with other vendors. I would say, generally speaking, we are happy with it.
How was the initial setup?
The initial setup is a valuable point on Fortinet products. Most of the time, putting the theory into practice on the devices is quite friendly and straightforward. As long as you can read through the menus, you can find your way around the solution and make it work. A 10 minute surf through the tabs will give you an idea of what you can do and how to do it. Documentations and guides are also available when needed.
This is a high value point on Fortinet - the way everything is laid out in the web UI is user-friendly and quite straightforward.
What's my experience with pricing, setup cost, and licensing?
Generally speaking, Fortinet prices are competitive enough. It depends on the markets, but in our market, the price sensitiveness is high, especially now with the current economic situation after the COVID-19. This became something to take into consideration even more. Price is always important, but after such a situation, it's even more so. Customers became even more sensitive to the prices. So, price is another value point for Fortinet.
What other advice do I have?
If two-factor authentication is needed also for the end-devices, for example a endpoints or servers, I think FortiAuthenticator is not yet the most mature solution. However, if it is great for network devices, then this product is competitive enough price-wise and easy to use. It just works.
On a scale from 1 to 10, I would say Fortinet FortiAuthenticator is an 8.

A user friendly solution that covers a variety of use cases
What is our primary use case?
We connect FortiAuthenticator to different servers' active directories and use it for value authentication and VPN client authentication.
We use FortiAuthenticator for server login, terminal servers, Windows servers, and Linux servers. We have configured the solution for SSL VPN authentication with a Fortinet token.
What is most valuable?
The UI is user-friendly.
For how long have I used the solution?
I've used the solution for three or four years.
What do I think about the stability of the solution?
Fortinet FortiAuthenticator is highly stable.
What do I think about the scalability of the solution?
I rate Fortinet FortiAuthenticator's scalability a ten out of ten. Our clients are typically medium or enterprise-sized. Small customers typically don't use FortiAuthenticator.
How are customer service and support?
We haven't raised tickets for FortiAuthenticator, but Fortinet's support is very good. We found a block in FortiGate, and I had to open a ticket in FortiMail, but the public documentation is very helpful.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup is easy. Only the Fortinet Access Control is difficult. The network access control solution is a difficult topic as well. It's not that the product is difficult. It's the environment, connecting to the switches, the firewalls, the zones, and the difficult appliances. FortiAuthenticator is easy to use and install.
However, I know FortiAuthenticator, so the initial setup was easy when I saw this product. The initial setup for all of the Fortinet products is typically easy.
The deployment time depends on the difficulty of the destination environment. Our last installation took four days. After that, we created the system's documentation, which took one day.
What other advice do I have?
I rate Fortinet FortiAuthenticator a nine out of ten.
Which deployment model are you using for this solution?
On-premises

Simple to deploy and very user-friendly
Pros and Cons
- "Simple to deploy, simple to use, and user-friendly."
- "Lacks a simplified two-factor authentication process."
What is our primary use case?
Our company is based in Latin America and we work mainly in areas relating to telecommunications in the banking, retail and public sectors. We are partners with Fortinet.
What is most valuable?
The solution is simple to deploy, simple to use, and user-friendly.
What needs improvement?
I'd like to see a simplified two-factor authentication process and some additional security around the function of geolocation. If you can't authenticate to protect transactions, and the security is weak, it's a problem.
What do I think about the stability of the solution?
If you have the correct architecture, the solution is stable. If there are a large number of users, there are likely to be some stability problems.
What do I think about the scalability of the solution?
The solution is scalable.
How are customer service and support?
We're happy with the customer support.
How would you rate customer service and support?
Positive
How was the initial setup?
The initial setup was straightforward. The solution functions 24/7 so the admin, operation and maintenance need to be in good shape round the clock so we generally have four engineers involved in maintenance.
What other advice do I have?
I think this is a good solution although there are some things that need to be improved so I rate this product eight out of 10.

It keeps track of users and their IPs no matter where they are in the network
Pros and Cons
- "It keeps track of users and their IPs no matter where they are in the network. When users roam, we don't have to worry about not mapping them to an IP."
- "Valuable features include the robust SSO features, when you have more complicated authentication within an organization. We can mix AD, Radius, Portal, SSO Portals (Google, etc.), and build our own environment. It is very flexible."
- "The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
What is our primary use case?
We implement FortiAuthenticator in situations where there are multiple Active Directory domains. Other use cases include:
- When we need to use FortiClient to keep track of users as they move around different locations where normal FSSO would have issues
- When we need to use one FortiToken for multiple Fortigates
- When we want to use it as a domain controller.
The FortiAuthenticator can do many things.
How has it helped my organization?
It keeps track of users and their IPs no matter where they are in the network. When users roam, we don't have to worry about not mapping them to an IP.
What is most valuable?
Valuable features include the robust SSO features, when you have more complicated authentication within an organization. We can mix AD, Radius, Portal, SSO Portals (Google, etc.), and build our own environment. It is very flexible.
What needs improvement?
The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated.
For how long have I used the solution?
One to three years.

It integrates very tightly with the rest of the Fortinet ecosystem.
Pros and Cons
- "It integrates very tightly with the rest of the Fortinet ecosystem."
- "A better integration with other vendors."
What is most valuable?
Integrated RADIUS server with 802.1x functionality and access control. Single Sign On and AD integration. It integrates very tightly with the rest of the Fortinet ecosystem.
How has it helped my organization?
It integrated with the existing Cisco wireless infrastructure to solidify the way people authenticate onto the network. It permitted having a centralized area to authenticate all users and enabled SSOimplementation.
What needs improvement?
A better integration with other vendors. The device is rich in features but there are a lot of functionalities I have still not experienced with.
For how long have I used the solution?
Two and a half years.
What do I think about the stability of the solution?
Overall not really, a few hiccups with the syncing with AD but nothing major.
What do I think about the scalability of the solution?
Not in my experience. The device can scale on a VM with an additional license. And there are boxes that can support thousands of users (which I have still not met).
How are customer service and technical support?
Very good. In our area we get support both in French and English and the response times are usually pretty decent.
Which solution did I use previously and why did I switch?
We are a Fortinet reseller and integrator so there were no "switches" per say.
How was the initial setup?
The setup process can be tedious.
What's my experience with pricing, setup cost, and licensing?
I would start off with a VM including the base license and scale according to the number of users you need to authenticate.
Which other solutions did I evaluate?
ClearPass by Aruba and ISE by Cisco are the two main competitors in this space. To me ClearPass seams to be the most feature-rich solution for the price and vendor neutral as is FortiAuthenticator.
What other advice do I have?
I strongly recommend someone accompany you in the initial deployment of the product to view all the functionalities that the platform is capable of doing.
