VPN technology enables internet users within an organization connect to their network and work virtually from any location. These people can be employees in different geographic locations. Others can be in remote areas such as offshore oil rigs or mining areas far from civilization. The connection is very secure and efficient meaning work flow is not interrupted. An outsider cannot read any intercepted data since it is already encrypted.
On the other hand, a proxy refers an application or system whose function is acting as a go between for users searching for resources from other applications. In IT jargon, such an application is known as a server. So, whenever you need a service, you are connected to such a server from another one. The proxy server appraises your request and simplifies it for you. In the end, you get what you are looking for. These activities are electronically controlled and happen very fast such that you will not be able to notice.
The proxies in use today are known as web proxies. Their work is to facilitate access to internet content. Here are the potential uses of proxy servers.
– They help keep machines in a network secure.
– They hasten the process of accessing resources.
– Prevent a multiple download of similar content thus saving bandwidth.
– They provide a log on how employees use the internet.
– They scan all incoming and outgoing content for risks such as malware or data loss
For comparison purposes, here is what a VPN does:
– Connects users to the business network.
– Allows you to work from home or another location.
– Users exchange data and other useful information in real time.
1. Proxy servers and VPNs
They act as connectors allowing you to get through to other resources within a network. The server need not located in your locality, it could be anywhere. Proxies are responsible for the requests you make to connect to a webpage or files. From where you sit, you are oblivious of the operations taking place behind the scenes. Since the connections may not be always secure, you need a VPN to encrypt the information going back and forth
A proxy server is merely a conduit and can allow any kind of data to pass through. Going by the fact that the internet is a public place, you need to ensure that there are no unwanted elements within your intranet. Third parties can gain access to your data with dire consequences on your part. To clean and keep them out, VPN connections secure the transmission of data. In addition, VPNs facilitate this transmission either within a small or large geographical area.
3. Privacy and confidentiality
An anonymous proxy server is well able to secure any computers behind it as well as maintain privacy. Free proxies on the other hand are slow in connectivity. This hinders timely transfer of data and can lead to spamming. To cut the slack and increase efficiency, a VPN network is required. This helps make you networks reliable and maintain data confidentiality.
