HIP 8.0 does not have a build package without IPS; there is only 1 installer. You can purchase HIPS as Firewall only, which basically doesn't activate the IPS functionality, but it is still only one installer. The full HIPS software is installed with IPS/FW, but if you don't activate the IPS functionality, it just shows Firewall functionality in the ClientUI.
Are they referring to the ENS software? Endpoint Protection 10.1 includes Firewall functionality, but not (full-blown) IPS functionality (yet). It does have limited IPS functionality included though.
That answers the question perfectly. No, they're not referring to ENS,I think they just mis-read the download from McAfee where the actual .zip file says something like: HIPS without IPS or something like that.
