Hello Experts, I would like to extract reports based on the TLS version being used by the endpoints, as seen here: But, was not able to locate such a filter on ISE Reporting, any pointers to the same? Or is this something that cannot be extracted from ISE?
AKAIK there is not a direct report you can run to target that. However, you could run a report on Top N Authentication by Failure Reason, and create a rule like this: Failure reason contains TLS. This would report how many endpoints are failing auth due to TLS issues. Do you use the ise posture module? If so, you could setup a registry check to determine what your hosts are configured to use from a Windows perspective: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\RasMan\PPP\EAP\13. That key is specifically applicable to EAP TLS and PEAP. There may be some other keys you could leverage as well. Good luck & HTH!
