Cisco Duo is a simple and effective tool that gives detailed information about users who connect to your domain. You can review the logs, including the public IP that the user uses, which country the user is in, and the city where the user is located. Everything is perfect in the logs. One tab shows that a user, for example Hasnain, is connected through remote access VPN and is using a specific public IP from a particular city in a specific country.
Cisco Duo offers a great logging solution in a Cisco environment. Additionally, Cisco Duo integrates easily with single sign-on apps, and I have used it on the Cisco ISE side because you can add the Cisco Duo address to your ISE and create the same user in both Cisco Duo and Cisco ISE. This makes it easy to manage, as Cisco ISE directly sends requests to Cisco Duo to verify, and the user logs in with a push notification or SMS code.
I am using many features in Cisco Duo, including logging in to Cisco ISE, sending requests when I log in to Cisco FTD through Cisco Duo, and checking 2FA on Cisco AnyConnect. Additionally, I have installed Cisco Duo app on my Windows-based machine, which checks for 2FA notifications every time I reboot the system or press Windows + L. This sends notifications to the cloud to check the username, and it also provides features that ensure the Windows Firewall is always enabled and verify that sensitive data partitions are encrypted. Moreover, it checks that antivirus is properly installed on the system. I also integrate my app within my company and have implemented single sign-on services through Cisco Duo, which is outstanding.
