VPN

Many businesses deal with a global market rather than with just local clients. Most companies today have their business interests spread out across the country or around the world. These companies need a means to conduct fast, secure and reliable communication. VPN provides a convenient way to do so. It is a private network that uses a public network such as the internet to connect remote sites or users together. The VPN technology doesn't use a leased line. Instead, it uses virtual connections routed through the Internet from the private network of the company to the remote site or employee. The advantage of VPN is that it provides an organization with the same capabilities as a leased line, but at a much lower cost.

VPN uses a shared public infrastructure. It maintains privacy through security procedures and tunneling protocols like the Layer Two Tunneling Protocol (L2TP). This protocol sends the data through a ""virtual tunnel"", It encrypts the data before sending it and decrypts it on receiving it at the other end. Security can be further be tightened by encrypting the originating and receiving network addresses.

A secure VPN uses cryptographic tunneling protocols. This provides the necessary confidentiality, prevents unauthorized access and protects private data. Proper selection, implementation and usage of a VPN system can ensure secure communication over an unsecured network.
Using a proxy anonymizer is the most common method of anonymous surfing.

A number of free proxy anonymizers use proxy servers from free, open, proxy lists. Many of these lists do indicate whether a proxy is anonymous or not, but sometimes they are not accurate or up-to-date. You will need to be aware that everything you do via these free proxies can be logged and used by the proxy administrators for their own interests and uses. Another problem is that malicious hackers (crackers) and spammers set up proxies in the free proxy lists and can use this source to integrate your computer or collect your personnel information to later send unsolicited emails to you.

To anonymize ALL your connections, you will need to use an https proxy anonymizer -- commercial or free proxy anonymizers that use SSH or SSL encryption between the proxy server, website and your computer. Inevitably, by using commercial or free proxy anonymizers, you will have to expect a certain slowdown in your connection speeds. When using an http proxy anonymizer-- http is a standard, unsecured connection -- your IP will not be visible.

VPN connections:

A VPN anonymizer is a technology that establishes a private or secure network connection within a public network, such as the Internet.

VPN or what are commonly known as VPN (Virtual Private Network) tunnels, are frequently used by corporations and government bodies, to allow remote workers to make secure internet connections to the office network. VPN is currently the most advanced form of anonymity and data security for use on the Internet. VPN users often have dynamic IP addresses and can have a different IP address with every connection that they make. The main difference between an SSL or SSH encrypted tunnel proxy and VPN (Virtual Private Network) tunnelling, is that VPN doesn't use a proxy and anonymizes and encrypts all activities. Both SSL and SSH encryption can be used with VPN as well as proxy servers.
