A free proxy service is good, but a VPN is even better…

The basics of using a proxy server for privacy and security

Highlights of Touch VPN: No credit card information needed. No session, speed or bandwidth limitations. Our strong SSL encryption will make you fully anonymous and secured. If you have any feedback or suggestions, please send an email to: When connecting to a VPN server through Touch VPN for example - it sets up a secured and encrypted connection to the server in another country.

Because of the encryption process the data cannot be filtered or blocked. A Proxy server is however, completely browser based, whether you are using Chrome, Safari, or Firefox; and might not be compatible with certain web pages that use non-browser technology. Unlike a Proxy, a VPN service encrypts all your traffic, and will work with all internet based services.

In summary, VPN will provide you with more online freedom, privacy and security. In what is more of an inconvenience than a risk, proxy users may find themselves being blocked from certain Web sites, as numerous forums and Web sites block IP addresses from proxies known to have spammed or trolled the site. Proxy bouncing can be used to maintain privacy. A caching proxy server accelerates service requests by retrieving content saved from a previous request made by the same client or even other clients.

Caching proxies keep local copies of frequently requested resources, allowing large organizations to significantly reduce their upstream bandwidth usage and costs, while significantly increasing performance. Most ISPs and large businesses have a caching proxy.

Caching proxies were the first kind of proxy server. Web proxies are commonly used to cache web pages from a web server. A proxy that is designed to mitigate specific link related issues or degradations is a Performance Enhancing Proxy PEPs. These typically are used to improve TCP performance in the presence of high round-trip times or high packet loss such as wireless or mobile phone networks ; or highly asymmetric links featuring very different upload and download rates.

Another important use of the proxy server is to reduce the hardware cost. An organization may have many systems on the same network or under control of a single server, prohibiting the possibility of an individual connection to the Internet for each system.

In such a case, the individual systems can be connected to one proxy server, and the proxy server connected to the main server.

A translation proxy is a proxy server that is used to localize a website experience for different markets. Traffic from global audiences is routed through the translation proxy to the source website. As visitors browse the proxied site, requests go back to the source site where pages are rendered. Original language content in the response is replaced by translated content as it passes back through the proxy. The translations used in a translation proxy can be either machine translation, human translation, or a combination of machine and human translation.

Different translation proxy implementations have different capabilities. Some allow further customization of the source site for local audiences such as excluding source content or substituting source content with original local content. An anonymous proxy server sometimes called a web proxy generally attempts to anonymize web surfing.

There are different varieties of anonymizers. The destination server the server that ultimately satisfies the web request receives requests from the anonymizing proxy server, and thus does not receive information about the end user's address. The requests are not anonymous to the anonymizing proxy server, however, and so a degree of trust is present between the proxy server and the user. Many proxy servers are funded through a continued advertising link to the user. Some proxy servers implement a logon requirement.

In large organizations, authorized users must log on to gain access to the web. The organization can thereby track usage to individuals. Other anonymizing proxy servers, known as elite or high-anonymity proxies, make it appear that the proxy server is the client. A website could still suspect a proxy is being used if the client sends packets which include a cookie from a previous visit that did not use the high-anonymity proxy server.

Clearing cookies, and possibly the cache, would solve this problem. Advertisers use proxy servers for validating, checking and quality assurance of geotargeted ads. A geotargeting ad server checks the request source IP address and uses a geo-IP database to determine the geographic source of requests. A proxy can keep the internal network structure of a company secret by using network address translation , which can help the security of the internal network.

Proxies can also be combined with firewalls. An incorrectly configured proxy can provide access to a network otherwise isolated from the Internet. Proxies allow web sites to make web requests to externally hosted resources e. Proxies also allow the browser to make web requests to externally hosted content on behalf of a website when cross-domain restrictions in place to protect websites from the likes of data theft prohibit the browser from directly accessing the outside domains.

Not to be confused with secondary market , secondary market brokers use web proxy servers to buy large stocks of limited products such as limited sneakers [12] or tickets.

Web proxies forward HTTP requests. This request is sent to the proxy server, the proxy makes the request specified and returns the response. Also known as an intercepting proxy , inline proxy , or forced proxy , a transparent proxy intercepts normal communication at the network layer without requiring any special client configuration. Clients need not be aware of the existence of the proxy.

A transparent proxy is normally located between the client and the Internet, with the proxy performing some of the functions of a gateway or router. In a security flaw in the way that transparent proxies operate was published by Robert Auger, [15] and the Computer Emergency Response Team issued an advisory listing dozens of affected transparent and intercepting proxy servers.

Intercepting proxies are commonly used in businesses to enforce acceptable use policy, and to ease administrative overheads, since no client browser configuration is required. This second reason however is mitigated by features such as Active Directory group policy, or DHCP and automatic proxy detection.

Intercepting proxies are also commonly used by ISPs in some countries to save upstream bandwidth and improve customer response times by caching. This is more common in countries where bandwidth is more limited e. Firstly the original destination IP and port must somehow be communicated to the proxy. This is not always possible e. There is a class of cross site attacks that depend on certain behaviour of intercepting proxies that do not check or have access to information about the original intercepted destination.

This problem may be resolved by using an integrated packet-level and application level appliance or software which is then able to communicate this information between the packet handler and the proxy.

Intercepting also creates problems for HTTP authentication, especially connection-oriented authentication such as NTLM , as the client browser believes it is talking to a server rather than a proxy.

Criminals also make heavy use of proxies to obscure their actual locations. They can even chain proxy servers together to increase the difficulty of being tracked.

But proxies are used for a lot more than just to watch the latest Family Guy , or commit crimes. A lot of people use them simply for safety. If you have a slow Internet connection, you could use a proxy server with a lot of bandwidth, and malware threats roaming the net trying to find unpatched systems, or launch potential denial of service attacks, would find only the proxy.

Security researchers also love proxies. When you're trying to infiltrate the criminal underground, the last thing you want is to give them your home address. As you can see, proxies provide security and anonymity that can be very handy. If you don't have a corporate VPN you can use, there are a lot of services that offer some alternatives.

One of the most popular right now, and the one I've used, is called Hide My Ass. While the name may sound strange, I've had some good success with it.

One of the things I like about it is that, first, it provides a very easy-to-use client software. Instead of having to configure the proxy settings manually, you simply install the client, and it keeps track of your connection status, allowing you to set preferences.

This means you can connect to any of those servers and appear to be from that location. Finally, there are some things you need to keep in mind when using proxies. First, remember that while a proxy server will provide you with security and anonymity, the proxy itself has to decode your traffic to send it through. This means it can see everything you're doing, unless you use SSL connections.

So you need to trust it. A lot of people use TOR , which is a free anonymity network run by volunteers, or some go to underground channels to get so-called "private" proxies, but the problem is you never know if you can trust those servers. It may end up being worse than not using a proxy at all. Popular commercial services like Hide My Ass base their business on providing this service, so personally I have more faith in them.
