Featured Reviews

Charles Slaustas - PeerSpot reviewer
Information Technology Contractor at Insight global
Supports seamless authentication for users across multiple organizations and personal portals
The features I use in Cisco Duo include Duo Pushes to confirm my identity to the device, and eventually as MFA security was increased, I actually had to use exchange passcodes. Sometimes, I have to go into the site and get into Cisco Duo to retrieve the passcode, and many of them have been two-factor, where the sites send a passcode that I have to enter into Cisco Duo. It has been more of the latter. I have not seen issues with lagging or crashing on Cisco Duo's end; it was usually on the client end, often because someone set up a bad upgrade or there were connection issues with the Cisco Duo cloud through the administrative site.
reviewer2848395 - PeerSpot reviewer
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.
Mohamed Fouad - PeerSpot reviewer
Cybersecurity Team Leader at EMAK For Computer Manufacturing (ECM)
Network access control has centralized device profiling and automated user isolation
The best features Fortinet FortiNAC offers include great integration with other Fortinet products. We have most of the cybersecurity products from Fortinet, including FortiMail, FortiGate, and FortiManager, among many Fortinet products. The best feature is the integration with these products. Fortinet FortiNAC can also integrate with any switching vendor using SSH to manage switches. This integration capability is very beneficial. The integration with other Fortinet products and managing switches from different vendors has helped my workflow by providing automation that makes it easy to run actions. We execute and trigger actions through Fortinet FortiNAC on FortiGate. We set up trigger actions on FortiGate to be run through Fortinet FortiNAC directly. Whenever an action happens, it is triggered on Fortinet FortiNAC, allowing us to disable and isolate a user if that machine is infected. The automation and response functionality is powerful, and the integration is very good. Fortinet FortiNAC has positively impacted my organization by allowing us to control our network and save time. We manage multiple switches that allow many users, including guest users and corporate users. We have saved time and secured our resources while accomplishing a lot with Fortinet FortiNAC.
