Cisco ISE - The Segmentation Journey Part 2

As organizations continue to deploy wireless solutions, they can’t forget about the wired side. Security is still needed on those switch ports and you should know what devices are connected. Cisco ISE can help with the visibility and control for wired devices as well.

Segmentation is not just a check box that you check and you are done. It involves different solutions, layers that you have to take into consideration.

In an effort to make things dynamic and scalable, Cisco Identity Services Engine can help orgs implement TrustSec.
