VPN's with SSL, this is a relatively new thing. I could be wrong but I think it may have only being introduced (to Microsoft products anyway) with server 2008. The whole idea is that alot of public WAP's, such as hotels, cafes, pubs etc don't have the right ports open to allow pptp traffic. If this is the case you have to do without your vpn or start asking for the admin to configure the router. So now with VPN with SSL eliminates all these problems and hopefully guarantees you your VPN anywhere you go.
SSL (Secure Socket Layer,) is a protocol. Most Cisco VPNs will use SSL as their security protocol, so there is no difference between Cisco VPN and SSL VPN.
For a single application, SSL VPN can be very good because it allows very specific access control. SSL VPN hardware can be pretty expensive, so IPSec VPN is a good alternative, though generally more permissive.
Virtual Private Network Advantages :Users working at home can use the VPN connections to connect to their company's private network. Organizations can use VPN connection to establish connections with geographically separate offices using the public network like internet. Communication over VPN connection is more secure because VPN uses the following two protocols for data encryption: Point-to-Point Tunneling Protocol (PPTP) Layer Two Tunneling Protocol (L2TP) with Internet Protocol security (IPSec)

VPN Concentratorsare the ideal device when you require a single device to handle a large number of incoming VPN tunnels. VPN concentrators also allow for greater security from one of two architectures: SSL VPN or IPSec VPN. Some concentrators only offer support of one protocol or the other, whereas Cisco and other vendors advertise the ability to utilize either with their concentrators. The traditional tunnel for VPNs relies on IPSec, which resides at the network layer of the OSI model. At this level, a client is considered a virtual member of the connected network and can pretty much access the network as if locally connected. Therein lies a positive aspect of IPSec: Apps run without any awareness that the client is coming from outside the network. The drawback is that additional security controls have to be configured to reduce risks. For a client to access the IPSec VPN, it must have the client-side software configured. While this adds security, it provides additional cost to implement and leads to additional time and energy spent by tech support. This is what leads many toward an SSL solution. SSL is already built in to the capabilities of pretty much all computers through Web browsers. Thus, there is no additional work to install and configure the client side. In addition, rather than residing at the network layer, allowing access to all aspects of a network, SSL lets administrators allow access a bit more precisely toward applications that are Web-enabled. In addition, administrators can establish a finer level of control over uses with SSL VPN connections. On the negative angle, however, being that you can only utilize SSL VPNs through a Web browser, only Web-based applications will work. With a little bit of work, you can Web-enable additional applications, but this adds to the configuration time and may make SSL an unattractive solution for some.
Juniper is a vendor or manufacturer of Firewall appliances. Juniper also manufacters and sells routers, switches, IDP/IDS devices and SSL-VPN appliances.
The SonicWall VPN client is a hardware based networking device that connects the client with a desired VPN server to build a virtual private network for transferring data over a so called secure VPN-tunnel.
Simple answer: You don't. You get lucky and find a working free proxy. Free proxies are worthless, they will not keep your internet usage anonymous, they are always insecure which means you will leak information. Paid SSL Proxies and VPN's are the only way to ensure anonymous surfing and will always work.
Cisco Systems VPN Monitor is a Web-based management tool that allows network administrators to collect, store, and view information on IPSec VPN connections.

VPN's are only as secure as the remote computer is. If you use a family computer as the remote PC, then you have to make a decision to turn off the VPN when it is not being used by the appropriate person. VPN's are only as fast as the slowest internet connection between the two, so it is not exactly like working at your desk.
