How the VPN Network Works and Why You Need it

VPN is an acronym for Virtual Private Network. It is the VPN network that allows you to access and share any information remotely in a secure, private and encrypted tunnel as it routes through the public networks like the internet. It protects your data on the internet against all types of online frauds and threats. 

The VPN network can enable complete anonymity and security in any transaction on the internet.  It is a way to ensure nobody can learn about the origin and destination of transactions. Because of its encryption, it is safe from ISPs, internet hackers, and other regulatory bodies. They technically work like Wide Area network(WAN) where the primary node or the main office retains the security, functions, and features while connecting to remote data centers or branch offices. 

Most organizations and individuals are seen applying these networks on a peer to peer basis for secure transactions. Even if intercepted by the fraudsters, it will not render any damage because of its encrypted form. 

The VPN network works as a useful tool for businesses that have employees accessing the office servers from remote areas. People using their mobile devices to get information from their office applications can connect from any location in a safe and secure way without risks of internet frauds. It can completely secure your internet activities as you can enable masking your IP address. The virtual private networks can also connect an organization having several branch offices using LAN (Local Area Network). The most common use has been to hide crucial the internet data from third-party agencies. 

People who some level of technical expertise and understand that by using the public network like the internet, they are at a risk of getting their personal and financial information stolen (credit card details, emails being exposed etc.). They are aware that with a VPN their information is safe even while they are moving to different locations using different IPs. People can get access to many of the restricted networks with a VPN like unblocking TV shows, or social media sites even at locations where they are banned. The primary purpose is to hide the identity of the user. 

1. Remote Access VPN:  This enables the users to connect to a private network and avail the services and other resources from any remote location. The connection is done via the internet in a totally secure and private manner.  This system is ideal for both individuals and organizations. 

2. Site to Site VPN: This is an ideal solution for corporate houses that has its branch offices spread across different locations. The site to site VPN connects one branch with the other and is referred as intranet VPN while when an organization connects to another company office, it is called extranet VPN.

The service providers offer monthly or yearly plans for the home users which allows them to have anonymous and private browsing do other online activities without any external control.

 

Virtual private networks can be totally software-based i.e. the client and server software or it can be a blend of hardware and software where the client software connects to a router. 

SSL VPN is another method where a user can connect using their web browser without the necessity of any special client software. SSL enables better control. They provide tunnels to specific applications as required, rather than to the entire LAN system. A business can thus provide different access privileges to different employees or users as per their requirements.
