”Key Features and Benefits
Ibrahim M., Senior Network & Security Engineer at a tech services company, relates, "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."
Fortinet FortiAuthenticator was previously known as FortiAuthenticator.

| Author info | Rating | Review Summary |
|---|---|---|
| Senior Network and Security Engineer at Symbol Technologies PLC | 3.5 | We deployed Fortinet FortiAuthenticator for a client's authentication on Cisco devices. Its integration capabilities and compatibility with FortiToken and zero trust access enhance security. Migration challenges to OpenStack exist, but overall, it positively impacts security costs. |
| Assistant Manager-Networks at a university with 1,001-5,000 employees | 5.0 | I've used Fortinet FortiAuthenticator for five years to securely authenticate admin users, especially for remote and VPN access, and I appreciate its global access, strong logging features, and reliable support, despite minor glitches and lacking AI features. |
| Network Engineer at Coop Money | 4.0 | I use Fortinet FortiAuthenticator for multi-factor authentication due to its easy deployment and solid GUI, though support could improve. It's stable, scalable, affordable, and ideal for small to medium enterprises, but not preferred for larger organizations. |
| CTO at Exceed NetSec LLC | 4.0 | I use FortiAuthenticator for two-factor authentication, finding it effective once configured correctly, but transferring it after losing a device is challenging and slow. The return on investment is hard to gauge, but it is essential for security compliance. |
| Head of computer systems at Indian Institute of Space Science & Technology(IIST) | 2.5 | We use Fortinet FortiAuthenticator for token-based authentication for wireless access and SSO. The product is cumbersome, requires daily re-authentication, and lacks maturity, prompting us to consider replacing it with Duo. It does not meet our needs effectively. |
| Senior Manager at Allsec Technologies Ltd | 3.0 | We use Fortinet FortiAuthenticator for two-factor authentication, especially for remote VPN needs, benefiting from a perpetual license. While it aids compliance and reduces costs by 50%, we seek better application solutions and consider alternatives like ManageEngine for enhanced features. |
| DevOps Engineer at YASH Technologies | 3.0 | We use Fortinet FortiAuthenticator for Single Sign-On with Active Directory credentials to access cloud and on-premises environments, appreciating its multi-factor authentication and password enhancements, though technical support needs improvement. We deploy it on Microsoft Azure. |
| System&Network Administrator at Spearhead Networks | 4.0 | I use Fortinet FortiAuthenticator as an IAM tool; I value its token usage capabilities. However, its customization is limited, making personalization challenging for clients. Despite this, it offers value for money, although some opt for cheaper alternatives like Sophos. |
