Is it possible to recognize and block iphone userss (using IPSEC VPN Client) from accessing corporate VPN ? We have a typical setup of multple ASAs, cluster, for different types of groups. Corporate support is for desktops with installed cisco vpn client 5.x. We know the iphones have inherent cisco vpn client (or downloadable) that can be configured to act as a vpn client. Corporate is not ready to support it. But, wondering if there's any technical way to recognize and block it (i doubt .. but checking just in case).
ps.. i know for ssl we'll need the license for macOS. But, the above question is for ipsec vpn.
