Xsec support has been deprecated as far as I know (it was years ago), so there would not be any Juniper/Funk (now Pulse?) that supports xSec for Win10. The last AOS version supporting xSec is AOS 6.4 only on Gen 2 controllers (M2/3x00/6x0). Xsec is not supported on any of the current ~7 year old controllers in the 7200 and 7000 series, or any new controllers moving forward.
So might be a good time to start moving to EAP-TLS? Windows natively support FIPS in their supplicant now.
