VyprVPN for Android, Mac OS X, Apple iOS, and Windows revs up your digital privacy.
A virtual private network (VPN) creates a secure network connection over a network you don’t fully trust, such as the Internet. By creating secure tunnels between endpoints, VPNs are a way of disguising (encrypting) your data traffic so that third parties (such as hackers, ISPs, and state-sponsored authorities) cannot see your true source IP address or the content of your online activities.
Many businesses, government agencies, and educational institutions use VPN technology to enable remote access for their users. With VPNs these users can securely connect to their work networks from their homes, airports, hotels, etc. What if you could connect not just to one destination, but to the whole Internet in such a way? After all, in light of the recent flood of revelations in regard to online spying committed by various facets of the American government (and by foreign states as well), all Internet users have a valid reason to increase their level of online privacy. VyprVPN by Golden Frog, a global online service provider, is an easy and highly effective way to do so.
The Onion Router (TOR) network is intended to help protect the privacy of Internet users and promote greater freedom of expression online. Tor is a system of volunteer servers that acts as a buffer between Internet users and the resources they connect to. If you connect as a Tor client, your online access is channeled through this buffer before it reaches the general Internet. To understand clearly how Tor functions, you must first have a good idea of what proxy servers are, and of the role they play during network transmissions.
A proxy server acts as a middleman between a client computer and the target server or resource it is accessing. As such, proxies can be configured to log user activity and restrict Internet access; for example, by blocking certain websites or protocols. However, proxies can also help protect the client user’s privacy because the target server is only aware that it is communicating with the proxy, not with the client. For example, if you connect to a web proxy and then load a website, the site is only aware that it is being accessed by the proxy and it has no knowledge of your computer and IP address. The illustration below depicts network data flow when a proxy is deployed. Resources within the Internet icon (such as web servers) are only aware of the proxy server, not of the three clients behind it.
Now what if instead of using a single proxy server, you could connect to a network of them for increased bandwidth and availability? And what if you could encrypt your communication sessions for increased confidentiality? Using Tor, you can.
