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.
Mahesh Malve - PeerSpot reviewer

Advanced analytics have strengthened privileged access security and reduced incident response time
While One Identity Defender is a strong solution overall, there are a few areas where I feel it could be improved. One area is the user interface and dashboard customization. Although it is functional, making it more modern and allowing deeper customization would improve the user experience, especially for quick monitoring. Another improvement could be in reporting flexibility. While it provides good reports, having more custom report building options and easier export features would be helpful for different compliance and manageability needs. From an integration perspective, while One Identity Defender works well with core systems, having more out-of-the-box integrations with modern cloud services and SaaS platforms would reduce the need for custom configuration. In terms of support, the overall support is good, but faster response times for critical issues and more detailed troubleshooting documentation would help teams resolve problems more efficiently.

Quotes from Members

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

Pros

"The solution is an integral part of our security for our email network, and like I said, we'll begin using it for other cloud applications."
"The solution's most valuable aspect is that it is easy to install and the user experience is very good."
"I am really impressed by the technical support because they were very helpful; once we logged our complaint, we received an answer from them in no time, and they quickly fixed our issue."
"FortiAuthenticator is really good software that integrates very well with Fortinet products."
"It integrated with the existing Cisco wireless infrastructure to solidify the way people authenticate onto the network."
"The product is good, cost-effective, and functionally efficient."
"FortiAuthenticator has made our operations secure."
"The most valuable feature is the flexibility in using the SMS messages."
"It's very fast, and it's easy to use because it's integrated with Active Directory."
"One Identity Defender has good network protection."
"One Identity Defender has positively impacted our organization by improving overall security through the addition of MFA, which reduces the risk of unauthorized access and makes user authentication more controlled and reliable."
"If you decide to activate this solution, your infrastructure will be centered around flexibility."
"One Identity Defender has good network protection."
"With One Identity Defender, we have achieved around 40 to 50% time saving in maintaining privilege access tasks."
"We find that the product scales very well."
"We have definitely seen a positive ROI from using One Identity Defender, as our security team now spends about twenty to thirty percent less time on manual log analytics and investigations because the system automatically highlights high-risk activities, and we did not need to increase team size despite growing infrastructure as the tool helps us handle more security events with the same team."
 

Cons

"A better integration with other vendors."
"I would like to see support for more credential authentication protocols."
"The GUI is on the older side but I'm sure that it will be upgraded soon. It works, but it looks a little dated."
"The only issue I encounter is that when not using FortiAuthenticator for an extended period, it's typical to encounter some obstacles in the configuration process that you need to address."
"I would like to see more ways to authenticate, such as adding facial recognition to the two-factor, where you log into your phone or another device."
"I would like to see integration and customization capabilities with the end-user portal to solve authentication issues with diverse implementation scenarios."
"One thing I dislike is that if you have the software authenticator on a mobile device and that device is lost, it's difficult to remove."
"The solution could be more automated. It should be able to let me automate a lot of things so that what normally is done as a matter of manual processes can be handled quicker. Slow integrations can be taken up/out if there was more automation."
"The only reason it is not a ten is because response time can sometimes be slower for complex or escalated cases."
"One Identity Defender can be improved by simplifying the user interface and making navigation more intuitive, especially for new administrators who may find the initial setup and policy configuration somewhat complex."
"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."
"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."
"One Identity Defender is a strong product, but there are a few areas where it can be improved."
"Maybe it could provide support for more web applications. It seems more focused on IIS web applications."
 

Pricing and Cost Advice

"It's not 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."
"When we buy the Fortinet FortiAuthenticator device there is a comparison between price and security."
"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 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."
"I rate the product price as two or three on a one-to-ten scale, where one is expensive, and ten is cheap."
"The platform provides a user-based pricing model rather than a subscription pricing model."
"The product has affordable pricing compared to other vendors."
