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.

Strong security has protected my online accounts and keeps my access safe across platforms
In my opinion, the best feature Google Authenticator offers is the way it generates the code every one minute or thereabout, and the code keeps changing, which enhances security. I am very sure nobody can have access to my accounts without Google Authenticator. Google Authenticator has impacted my organization positively as I have first-hand assurance that nobody is breaking into any of our accounts or websites, and it saves a lot. It gives you that assurance; it makes you feel very safe. The security is top notch, and it is even amazing that it works without the internet. What is really measurable is that we do not get our things compromised now. It is more secure; it provides comfortability knowing that my account is safe, and I feel more secure.

Quotes from Members

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

Pros

"For someone concerned with multifactor authentication, I'm satisfied with the product."
"The response from Fortinet is very fast."
"The integration into tools, including CI/CD pipelines, is easy and handy."
"Enables easy integration, allowing for 2FA with our VPN."
"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."
"The feature I value the most is the one-time passwords because it helps to authenticate users so you know the timing of their usage."
"Fortinet FortiAuthenticator has improved our organization because we are able to can create identity-based policies, for example, who are you and where are you, and we are shifting from the IP-based to the identity-based."
"I like the self-registration capabilities."
"Google Authenticator has positively impacted my organization by improving security and productivity."
"Google Authenticator has helped save money, save time, and maintain reputation because of the security it provides."
"The security is top notch, and it is even amazing that it works without the internet."
 

Cons

"The technical support team is bad."
"The interface is a bit misleading in areas."
"I would like to see more support from Fortinet with tech support people who have as much expertise on the authenticator as they do on their firewalls."
"Up to now, I would not recommend FortiAuthenticator to others yet as I have ongoing transitions and evaluations."
"The support team is pathetic and does not properly understand the solution."
"The product must provide 2FA for applications."
"Initially, we deployed Fortinet FortiAuthenticator on VMware and faced challenges when migrating to an OpenStack environment, which required reconfiguration. I recommend Fortinet make its images migratable between environments."
"It does not consider customer requirements."
"I deduct one mark due to the lack of a backup and restore option."
 

Pricing and Cost Advice

"The licensing structure is cost-effective for us compared to some of the other solutions that have recurring monthly costs."
"The solution is not very expensive."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"I rate its pricing a three to five out of ten."
"On a scale of one to ten, where one is a high price and ten is a low price, I rate the pricing a seven."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"The cost of the license could be less expensive. The license is paid on a yearly basis."
"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."
