Yes.
I randomly tested some of the newly published ISE 2.4 OVA files using either the vSphere Web Client (flash/flex client) or the vSphere Client (HTML5) to access the vCSAs in vSphere 6.5 Update 2 and vSphere 6.7 Update 1. In fact, the OVA files also deployable using the ESXi Embedded Host Client from these vSphere updates, if the ESXi not connected to the vCSA.
Thus, I made a suggestion to update the description as,
ISE 2.4 OVA file, compatible with the vSphere Web Client (flash/flex client) in vSphere 6.x and the vSphere Client (HTML5) in vSphere 6.5 Update 2 and above or vSphere 6.7 Update 1 and above.
I believe the files would work in vSphere 5.5 but not tested by our teams, so we are keeping the older files around.
