Supports secure remote authentication and provides comprehensive user activity tracking
The most important feature is the security capability because it provides a substantial amount of security for admin-related activities. Fortinet FortiAuthenticator can be used from anywhere in the world, and the authenticator services function globally. This global accessibility is one of the critical advantages, particularly since admin features are critical and security is a real concern. With Fortinet FortiAuthenticator, secure usage of firewall services and related functions is achieved. A complete log of all users who access the authenticator setup is maintained. Monthly logs are reviewed to check for any unnoticed activities. Each authenticated user's complete activity history is recorded. This logging capability allows for providing access to more admin users while ensuring security is not compromised and all users can be monitored.

"The solution's most valuable aspect is that it easy to install. The user experience is very good."
"The initial setup of Fortinet FortiAuthenticator was straightforward, working effectively out of the box."
"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."
"The most important feature is the security capability because it provides a substantial amount of security for admin-related activities."
"The ease of use is really nice. Using Authenticator, I've been able to actually work better on my authentication due to the fact that I have a single fabric to authenticate control from my firewall and on my access points. Authentication takes place from this area."
"I work a lot with Fortinet products and I call the support often; they are very quick to respond and the support is very good."
"This is a scalable product."
"We find that the product scales very well."
"One Identity Defender has good network protection."

Cons

"FortiAuthenticator's interface could be better."
"The speed of deployment on the cloud could be improved. It took a few days when it should have been just two days"
"The customization capability of Fortinet FortiAuthenticator is not very flexible."
"I think FortiAuthenticator is more expensive than other products like Cisco Duo."
"Integration with some other enterprise applications could be improved."
"I would like to see support for more credential authentication protocols."
"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 like to see some email options for Fortinet FortiAuthenticator."
"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
"The login capabilities could be better."
"We have some clients that are wanting to protect their Apache web servers with One Identity Defender but all the research I have done says cannot be done. It can only be oriented to an IIS server. One Identity Defender should have more integration with more types of web servers."
"The login capabilities could be better."
 

Pricing and Cost Advice

"It costs more to license the high-availability option."
"I would start off with a VM including the base license and scale according to the number of users you need to authenticate."
"I rate its pricing a three to five out of ten."
"The product could be more competitively priced."
"You can pay as you go with them. You purchase a base license and add to it as needed."
"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."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
