Overall Satisfaction with Cisco Identity Services Engine (ISE)

In our organization, We are using Cisco Identity Services Engine (ISE) as TACACS+ server for >5000 devices and as RADIUS authenticator for 802.1x (wired & wireless)

Pros

  • 1x
  • endpoint context
  • authentication

Cons

  • Cluster upgrade
  • Web portal management
  • Managing more than 5000 radius sessions without any issue
  • Managing more 7000 devices with TACACS+ without issue
It works, it's less expensive (incredible!), lower TCO.
