We use this solution for two-factor authentication of most of our services. It includes VPN but also many other services that we have on our internet servers. We use the on-premise version because we also want it integrated into our in-house applications. We are customers of Fortinet and I'm a systems administrator.
Systems Administrator at Interswitch
Easy to deploy with intuitive interface; integration with certain enterprise applications lacking
Pros and Cons
- "Intuitive interface and easy to deploy."
- "Integration with some other enterprise applications could be improved."
What is our primary use case?
How has it helped my organization?
Security is such a big issue these days, a password alone is no longer enough for securing identity. In that sense, providing a second layer of authentication for users gives the company some level of comfort.
What is most valuable?
I think the ease of deployment is a valuable feature. I like that the interface is intuitive and that natively and easily, it integrates with radios, ILDAP, fan mail, and with any applications supporting those protocols
What needs improvement?
I'd say that the integration with some other enterprise applications could be improved. For instance, ADFS. FortiAuthenticator does not work natively with ADFS and the company is not looking in that direction. It's one of our in-house applications and it was a challenge integrating with FortiAuthenticator. We had to write a separate, customized adapter for ADFS before we could make it work. We tried to get Fortinet to work on it but I don't think their development team is interested. It's not in their plan. The other challenge was when I integrated with I think VMware - there was an issue between the radio adapter and FortiAuthenticator. Both parties were not ready to work together and the implementation was buggy.
I believe this solution can be adapted to so many things, depending on the technical side and the implementation engineers. I'd like to see some additional use cases that can be infused into the solution, such as ADFS.

868,787 professionals have used our research since 2012.
For how long have I used the solution?
I've been using this solution for two years.
What do I think about the stability of the solution?
I haven't had any issues with stability.
What do I think about the scalability of the solution?
It's a very scalable solution. They now have the option of deployment as a VM, and then they have the hardware. I believe we use the 1000D for the hardware - it's able to support up to 10,000 users. You license the appliance based on the number of users and if you need to add more, you buy additional licenses. Almost everybody in the company uses it and I'd say we've had a total of around 4,000 users.
How are customer service and support?
The technical support is mid-range It's not your wow kind of support but they do have levels of support. The support is in connectivity with their clients and it has to be renewed every year. You might do better if you go through their partners or something similar. They're not really there when it comes to support.
Which solution did I use previously and why did I switch?
We used RSA SecurID before Fortinet. We switched because of the high costs associated with RSA. I believe that with RSA you need to pay a token license every three years but with Fortinet, once you buy it, you own it. Even if a token is lost, you can always reposition the token and that will not come at any extra cost. It's cost-effective for us. We also have several channels we can use for authentication with FortiAuthenticator. With RSA, users are stuck with either carrying the dongle, the hardware token, or maybe having the mobile application token on their phone. With Fortinet you can decide whether to use a hardware token, soft token, email token, push notification, or SMS. It gives us flexibility and comfort.
How was the initial setup?
Initial setup was pretty straightforward. We were up and running within three days. I carried out the deployment.
What's my experience with pricing, setup cost, and licensing?
The license is a one-off payment.
What other advice do I have?
Every environment is obviously different so each user needs to know what they are looking for, and make a decision based on that. This is a cost effective and flexible solution. If a company is looking to use it on their server, it's important to look at the integration channels and your environment, the support. It's important to know that the channels are supported.
I would rate this solution a seven out of 10.
Which deployment model are you using for this solution?

Solutions Architect at Exclusive GRP
Enables us to have multifactor authentication using two-factor authentication
Pros and Cons
- "For someone concerned with multifactor authentication, I'm satisfied with the product."
- "No SMS gateway from the ISP"
What is our primary use case?
I am a solution architect and my company works purely for Fortinet, implementing all versions on a daily basis, so we're not end-users. The company is an exclusive distributor implementing the product.
The primary use case of the product is usually for multifactor authentication using two-factor authentication with tokens. Sometimes people require two factors with a token. Sometimes they need the latest POC. I do a proof of concept for windows login. They need the agent who authenticates with SMS, token or email.
What is most valuable?
Usually, I do an integration with the firewall. I would prefer to do it with FortiGate, but sometimes I need to integrate as a radius client and it depends on which firewall. I prefer FortiGate. Sometimes they'll need to add an SMS as the second factor of the two-factor authentication. But usually, we do it as an unarmed radius FortiGate, or firewall would be for a radius client and radius server. Sometimes clients will ask whether we have integration with a social portal like Facebook, but we don't.
What needs improvement?
There aren't any major features that I think should be improved. I like this product. As a multifactor authentication, we have the SAML function. If you compare it with RSA or Gemalto, it does a good job. I'm able to perform multifactor authentication in different ways via emails, SMS, it's a great product. For someone concerned with multifactor authentication, I'm satisfied with the product.
There aren't any major additional features they could include in the next release but the one thing they used to include was the SMS gateway from the ISP. Fortinet used to sell that but they don't anymore and I think it would be helpful for end-users if they brought it back. I would recommend that. People are asking for it because they don't like having to rent it from their mobile provider.
For how long have I used the solution?
I've been using FortiAuthenticator for about a year.
What do I think about the stability of the solution?
The product is very stable. I love it.
What do I think about the scalability of the solution?
I think it's a scalable product. I haven't compared it to the competitors but it's scalable.
How are customer service and technical support?
Part of the reason it's such a good product is that I don't recall ever needing to call for technical support.
How was the initial setup?
Initial setup and configuration are very straightforward. From a technical perspective, you need to know where to do the PDS but if you have a technical background it should be very straightforward. I just bring the VM or the trial license and I start to do the POC, usually with the VM.
Initial setup and deployment sometimes need integration with FortiGate, and sometimes via the captive portal. It takes a maximum of an hour, but it also depends on the end-user and what they need to be integrated into the system, like features such as SMS gateway parameters.
What's my experience with pricing, setup cost, and licensing?
I think the setup cost is reasonable, and we don't need to renew the license. Sometimes there are extra costs for the VM. Our main competitors are RSA and Gemalto, and the Fortinet prices are very competitive relative to their prices.
What other advice do I have?
As a distributor of Fortinet, I would suggest people give this product a little bit of focus. I mean we can do well on this product if we concentrate on it. People don't know about the two-factor authentication and that it's easy and straightforward. We also include some features for free but I suggest that people using Fortinet just focus on this product. FortiAuthenticator has created a straightforward easy-to-use product.
I would rate it a nine out of ten. Not a ten because nothing is perfect.
Which deployment model are you using for this solution?

Sr Network Security Engineer at a tech services company with 501-1,000 employees
Offers good stability, easy to use and simple implementation
Pros and Cons
- "It is very stable. We have never had any issues with this solution."
- "There is a room for improvement. The log is a bit difficult to access, and searching the log codes is also a bit difficult. So it would be much better if, when we open a log, it could provide detailed information about errors, reasons for failure, and such."

How are customer service and support?
The customer service and support are awesome for FortiAuthenticator.
I've been using Fortinet for the last eight or nine years. So, for other professional solutions from Fortinet, the support is not so good. You have to open a case as usual, and some technical contact will get in touch with you if they're available. If not, we have to call a toll-free number manually, and they will connect us to an available agent who will check our case and then escalate it. For normal issues with no business impact, it's okay to wait for two or three hours, no problem. But in critical situations, it's challenging to reach them.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
How was the initial setup?
The initial setup is simple. It's not that difficult. You have to know the functionality of FortiProtect, the requirements, and it depends on your network. It's not that difficult to implement.
We have VMs and devices. But mostly, we are moving to VMs.
What about the implementation team?
We design and then, Fortinet team will implement.
What's my experience with pricing, setup cost, and licensing?
I would rate the pricing a four out of ten, where one is cheap, and ten is expensive. It is not that costly. It is cheap, easy to manage, easy to install, and easy to configure.
Which other solutions did I evaluate?
We evaluated Palo Alto. It's easy to use, offers a lot of features in one box, and it's cost-effective. And the support is very good.
What other advice do I have?
