Support for ISE and 3rd Party Firewall VPN Posture

Hello Everyone,

I would like to know, does the ISE support VPN Posture with 3rd Party Firewalls like Sophos.

VPN clients are terminated on Sophos Firewall and I need to do posture verification like Antivirus is installed and updated.

Is it possible with ISE 2.6 and Sophos Firewalls. If not, then would could be other possible solution.
