Featured Reviews

Yonas Abebe - PeerSpot reviewer
Integration capabilities simplify authentication and migration challenges need addressing
The integration capabilities of Fortinet FortiAuthenticator are very interesting, as it can be integrated with third-party devices easily and is straightforward to configure. The integration with FortiToken is outstanding, adding a layer of security for authentication. In addition, it can be used by integrating with zero trust single access, enhancing overall security measures.
OmerKhan1 - PeerSpot reviewer
A stable solution that is efficient, user-friendly, and easy to use
It would be better if the product can come up with a serial number for the keys. It would be nice if they had a numbering system as a configuration identity that would help the IT and technical teams to identify the keys because they look all the same. It would be more like putting a tag on them.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The web feature is quite versatile. It serves as the sole server authenticator and is valuable not only with FortiGate products but also within the entire Forti system, making it highly useful for me."
"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."
"We use multi-factor authentication for enhancing security."
"The most valuable feature I find in FortiAuthenticator is web filtering."
"The two-step authentication provides a higher level of security."
"The most valuable feature of the solution is RADIUS service and the social network integration feature."
"Once you configure it properly, it runs fine."
"Customer service and support are excellent."
"YubiKey is a hardware security device with advanced security features."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
"The most valuable feature of Yubico YubiKey is security."
"It's small and lightweight. Like a phone, it doesn't run out of battery. It also doesn't have to be unlocked. It doesn't break. Moreover, they're very durable and it's very convenient."
"The solution is simple to use and we have installed it in our clients' endpoints. The tool is just plug-and-play for the end user. The end user can just put in the key to the security computer and log in without any hassle. The solution is efficient, user-friendly, and easy to use."
 

Cons

"There have been numerous support tickets sent to Fortinet since this does not appear to be a mature product."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days"
"We have issues with HA (high availability). These should be addressed in future releases."
"No SMS gateway from the ISP"
"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"Other features that would improve the product are a single sign-on where people can use their Gmail ID to log-in, etc."
"For improvement, Fortinet needs to ensure that they provide quick support to users...Fortinet sometimes needs to respond to users facing issues within an hour."
"Currently, an area where the product lacks is in addressing service needs."
"Yubico YubiKey could be improved by allowing for centralized administration, which is not currently available in India."
"It would be better if the product can come up with a serial number for the keys. It would be nice if they had a numbering system as a configuration identity that would help the IT and technical teams to identify the keys because they look all the same. It would be more like putting a tag on them."
"Yubico YubiKey is inconvient. No one likes the idea of having to put a USB device into the system, having to remember to take it out, and having passwords. It may be very good for security but it is not great for people to use."
"It's a hardware device, so it isn't cost-effective to use for all your accounts. You might have a hard time getting budget approval. It's better to take a strategic approach and use it only for critical accounts. You can use other forms of authentication for the rest."
 

Pricing and Cost Advice

"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"I rate its pricing a three to five out of ten."
"Between paying them to help with the configuration, the box itself, and the support, it came to like $12,500, including a three-year service agreement."
"The solution is not very expensive."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The customers need to pay for licenses, and some pay on a yearly basis while others pay on a three-yearly or five-yearly basis. Also, it is not an expensive solution."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"We paid 100 bucks for one Yubikey."
