Technical Business Development Manager at a outsourcing company with 501-1,000 employees
Multi-factor security has improved device protection but still needs broader application coverage
Fortinet FortiAuthenticator could be improved in its cost structure. Although it is not expensive, other solutions offer more value for less money. Cisco Duo provides better value in this regard and connects to web applications much more easily, scaling effectively in that sense. While I have never used Cisco Duo to secure other devices in IoT environments, I know Cisco Duo is capable of doing so, whereas Fortinet FortiAuthenticator cannot. Additionally, Cisco Duo is also cheaper. These are the main reasons why we switched away from Fortinet FortiAuthenticator, as it was very limited compared to other solutions available. Fortinet FortiAuthenticator was primarily missing the ability to scale to web applications.

Sr Security Engineer at a tech vendor with 5,001-10,000 employees
Hardware authentication has reduced password resets and now secures access against phishing
The best features Yubico YubiKey offers are the major reasons we use it as a hardware MFA to create a token because it is phishing resistant. It guarantees the authentication works on a valid cryptographically verified domain, and it supports multiple protocols and authenticator capability. It is based on challenge-response mode, and it has extremely physical durability. It has a dual interface where you can plug it into a laptop or against an iOS and Android mobile phone. The private keys are generated directly on the internal secure chip and can never be exported by the host system or malware. Reducing password reset and MFA lockout support tickets by 75% has reclaimed the engineering capacity, which can be redirected towards more core infrastructure priorities, such as automating the security pipelines, improving asset management, and building internal CLI AI tooling. It has eliminated employee downtime and has simpler compliance and lower operational friction.

Quotes from Members

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

Pros

"I appreciate its ability to provide multi-factor authentication, but it's primarily focused on this function."
"The response from Fortinet is very fast."
"The solution is easy to learn and makes it easy for our users to add FortiToken, and it's very easy to integrate if you have other Fortinet devices."
"The logs have great detail that make it easier to evaluate and control the security environment."
"This is a scalable product."
"It reduces the need for network administrator intervention by allowing the user to perform their own registration and resolve their own password problems and issues."
"Fortinet FortiAuthenticator stood out for its robustness and reliability."
"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."
"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."
"The most valuable feature of Yubico YubiKey is security."
"Reducing password reset and MFA lockout support tickets by 75% has reclaimed the engineering capacity, which can be redirected towards more core infrastructure priorities, such as automating the security pipelines, improving asset management, and building internal CLI AI tooling."
"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."
"Yubico YubiKey is highly valued for its anti-phishing feature, which prevents phishing of OTPs that are normally obtained through phones."
"YubiKey is a hardware security device with advanced security features."
 

Cons

"The integration with third-party tools must be better."
"Fortinet FortiAuthenticator could benefit from some artificial intelligence functionality and resolution of some glitches that may exist."
"The integration with other products, for example, some SAML authentications, would make it more flexible."
"It does the job I paid for, but the graphical interface could be improved."
"We had some stability issues. Our first LBS unit wouldn't work properly the first time and that wasted a lot of time."
"It would be helpful to receive a code by yourself for authentication instead of it registered to a phone."
"It does not consider customer requirements."
"Fortinet FortiAuthenticator provides only authentication. It should also enable authorization services"
"Yubico YubiKey is one per user and I do not believe it is very scalable."
"Currently, an area where the product lacks is in addressing service needs."
"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 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 could be improved by allowing for centralized administration, which is not currently available in India."
"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

"The cost of the license could be less expensive. The license is paid on a yearly basis."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"The platform is cost-effective as it does not require a separate license for SD-WAN functionality."
"It's not expensive."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"The solution is not very expensive."
"It is usually cheap. Without a license, you can use some basic features. You can buy a 20-year license and implement the solution once."
"FAC is an affordable solution for Middle Range (200E/400E) and also needs a package of mobility agents (2,000) perpetual."
"We paid 100 bucks for one Yubikey."
