What to do next

The VPN dashboard is a complex, highly customizable monitoring feature that provides exhaustive data.

VPN Session and User Information

The Firepower System generates events that communicate the details of user activity on your network, including VPN-related activity. The Firepower System monitoring capabilities enable you to determine quickly whether remote access VPN problems exist and where they exist. You can then apply this knowledge and use your network management tools to reduce or eliminate problems for your network and users. Optionally, you can logout remote access VPN users as needed.

Viewing Remote Access VPN Active Sessions

Analysis > Users > Active Sessions

Lets you view the currently logged-in VPN users at any given point in time with supporting information such as the user name, login duration, authentication type, assigned/public IP address, device details, client version, end point information, throughput, bandwidth consumed group policy, tunnel group etc. The system also provides the ability to filter current user information, log users out, and delete users from the summary list.


Note

If you have configured your VPN in a high-availability deployment, the device name displayed against active VPN sessions can be the primary or secondary device that identified the user session.
