In the world of internet where extensively large amount of user traffic exists and data flows between servers and users, privacy of the user and data security is a great concern. Virtual private networks have been there for years to provide safe access to sites by acting as a proxy server link between public and private network. However in spite of these VPN providers claiming secure and private connection through various technologies like encryption, tunneling, firewall etc. the data may still be highly at risk. The beginning of internet era came up to change the face of humanity forever, changing lifestyles and human interactions. At the beginning the experts and technologists in the field may not have realized all the challenges and problems that one can face while browsing the internet. However as the amount of data and traffic increased on the internet, the security, safety and privacy came into picture more clearly.
A major problem that arose was accessibility to internet servers for surfing sites that were restricted and did not fall into its domain. Also connectivity amongst geographically separated servers through a secure connection was a problem.
The coming of the virtual private networks provided a solution and got highly popular amongst the internet users. The virtual private networks provide secure connections circumventing around restrictions and censorship on an internet network. They also help conceal the identity and location of the individual who desired to remain anonymous on the system by connecting to proxy servers. As secure access to private networks is considered to be extremely important now, VPN provides cost effective and an efficient way of connecting to internal networks from far locations or outside. VPNs do so by encrypting the data and increasing resistance from hackers and breaches and maintain the integrity of the connected networks. In a VPN only the authorized users are supposed to have access to the data that flows over the network. Any unauthorized access to the network is a cause of loss of privacy and data breaching. An important job of the VPN providers is the security provide by the VPNs. VPNs use tunneling protocols and encryption techniques to prevent disclosure of private information and gives access to only authenticated users. VPNs are not foolproof security providers as there are many loopholes in the entire authentication technique used by most of the VPNs available on the internet. VPNs can however increase security and privacy but the connections are not completely anonymous.
