Proxy Servers and VPNs
There are a lot of reasons someone might use a proxy server, like keeping a client machine anonymous, logging usage, scan for malware, or to bypass security controls that block certain sites (for when you really need Reddit at work). Proxy servers are an intermediary between your computer and another server that anyone can set up and use. A proxy server is like a stripped down version of a virtual private network (VPN).
Proxy servers are much simpler to configure, but they offer less protection for data.VPNs can be slower than proxies because they encrypt all data coming through the connection, whereas proxies only affect web traffic (that is, the internet as accessed through a browser). Many companies that offer proxy servers also offer VPNs for enterprise customers or people who have a strong need for encryption.
Astrill
Astrill has services in 48 countries and works with just about every operating system. Astrill allows users to set proxy settings up in their browsers (Internet Explorer, Chrome, and Firefox). Their main service is actually a VPN, which is like a proxy, but much more secure and limited to the machines on which it has been installed. Astrill encrypts data and keeps it anonymous which is particularly useful for people working or
traveling.
Hamachi
Hamachi offers a free, do it yourself proxy for those interested in learning how to configure their own network security. It is primarily used for limiting access to data
sent over an open Wi-Fi network or to bypass firewalls or filters. In order to set up Hamachi, two computers (one to be the proxy server and one as the client) are required. Hamachi is free as long as you don’t intend to use it for commercial purposes. It is easy to configure and budding network geeks will have fun working with it.
Private Internet Access
Private Internet Access is another service offering Web-based privacy protection.
It uses multiple security layers and VPN tunneling to make a secure connection.
Private Internet Access offers gateways in lots of countries and features gigabit
VPN
port speeds. Its IP cloaking feature hides the computer’s real IP address, replacing it with an anonymous one to create a private, undetectable connection. Private Internet Access also offers 128bit encryption that is based on Microsoft MS-CHAP
V2. Like the other proxy servers, it provides advanced firewall features both in terms of maintaining firewalls and circumventing the ones you don’t want in your way.
WiTopia
WiTopia is primarily a VPN provider, but it has a proxy service that is currently in
beta. The proxy service is faster than using a traditional VPN and is free for current WiTopia VPN subscribers. Using the proxy server, a user’s location and IP address becomes protected and anonymous to the server to which it is connected. It works for all standard Web traffic (i.e. not VoIP or other non-browser internet-using applications; that’s what VPN is for). WiTopia has built an auto-configure installer for users who want to set up the proxy.
