Internet vs Extranet

The comparison between internet and extranet will be incomplete without giving a view on what Internet and Extranet terms mean and their positioning in organisational IT setup –


The Internet is enormous global networked system that connects computer networks around the world together. Millions of private, public, business, and government networks worldwide connect with each other over the internet to share massive amounts of information and resources. Internet is what we use to access web pages, send e-mails, listen to music or watch videos online. It hosts an extensive range of information, one that we generally take for granted today.Internet is a low security entity and can be access by any individual in the world with access to Internet via dial up connection or leased line Internet.


An Extranet is basically a private network designed specifically to allow these individuals (clients, vendors, suppliers, partners, etc.) to communicate with you and your employees in a closed virtual space. Extranets serve an extremely important role, as they allow for private communication, collaboration, knowledge sharing, document sharing, and data transfer between organizations.  An extranet is accessible to some people from outside the company, or possibly shared by more than one organisation.This network system is basically used for business to business (B2B) purposes.

An Extranet can be used to meet a variety of different needs. Large volumes of data can be exchanged between parties via extranets, for example, and they can also be used to create collaboration. The latter is especially useful for companies that need to brainstorm or work back and forth with clients and customers, and it can save hours of time in comparison to using email and/or telephone. Extranets are also used to help monitor and fix any potential bugs or issues that can occur with a company’s products or services — almost like built-in quality control.
