ZoneAlarm Compatibility with Check Point products Updated July 30, 2019 00:19 ZoneAlarm's core firewall driver vsdatant is also present in a few select Check Point applications. Although the driver is not identical to the one found in Check Point products it does conflict when you try to install any ZoneAlarm product on the same PC with either the Check Point Endpoint VPN or Network Extender. The only solution available at this time is to uninstall ZoneAlarm or the Endpoint VPN / Network Extender.
