Is a VPN Better Than a Proxy?

VPN and proxy servers actually deliver the same function to users and that is to hide their identity every time they use the internet. Both proxy servers and VPN can also be used to hide geographical location particularly to allow access to videos and streaming websites that can’t be accessed by some point of origin and specific countries. There are even VPN servers that provide VPN protection as well as proxy services. The question people now ask is that, ‘Which anonymity tool is better? Is the VPN better than proxy servers?’

To answer this question, the best first step would be to know the difference between the two. As a start, there are actually different kinds of proxy servers. Proxy servers are actually preferred over VPNs because they are inexpensive and most of the time free. However, there could be risks involved. Proxy servers can indeed hide your identity while accessing information in the internet but they could also have access to sensitive data. There are also times that there will be too many users in one server and lag and hang-ups could be experienced. Government surveillance systems and tricks in Flash and Java may reveal information.

VPN servers can also hide your identity when accessing the internet. A VPN service can be compared to a tunnel of encryption. They are more secure compared to the proxy servers because of the levels of the encryption applied to hide browsing information. Internet service providers (ISPs) and government surveillance can actually see you access the VPN server but other than that, they won’t know what you are doing in the server. However, VPN servers can become expensive while proxy servers are free. This is the reason why there are still many who prefer proxy servers over VPNs.

Overall, it is really hard to choose between the two because each has its own pros and cons. However if we look at it, VPN is better in terms implementing internet anonymity. VPN can help you hide your activities while the same can’t be said to proxy servers because the data there can still be retrieved. However you need to pay a minimum fee before you can truly enjoy the full features of VPN servers. As a final tip, always remember that no tool can give you absolute security. When using both proxy server and VPN server, you must be vigilant so you can protect yourself especially when accessing the internet.
