cisco won't even be support IPSEC clients much longer, they are all SSL AnyConnect connections. All VPN is going over SSL TLS any more. Now if they go anyconnect support, that would be fine. Domain access is moving away from firewall based VPN to domain cert based SSL VPN back into Microsoft networks in the near future as well. Yes there is a lot of IPSEC VPN out there, (I do a ton of it and have 2 tests left for my CCNP +Security), but with no cisco support for IPsec vpn on windows 8, everything is going ssl client or clientless SSL portal for VPN.
