Difference Between Intranet and Internet

by Aaron Finch

In this article Mover Edge we’ll discuss the difference between Intranet and Internet.

Intranet is a private or closed network of computers within an organization that’s connected to the internet.

The intranet may be just a LAN, or as much sought out and used as the public internet.

For example, one company might need an intranet for compliance purposes that would use data sanitization technologies such as encryption and content filtering in order to ensure the company’s intellectual property stays secret from competitors by not having it uploaded onto public websites like Github or Mixcloud. 

The term Intranet is also applied to private internal networks in a company that connects to the internet but is not available to outside users. This normal closed network is specialized for internal communications among employees or for use by centralized business processes (e.g., in an airline). Intranets typically have no public interfaces, and are used by internal users only.

Advantages of Intranet :

1. It uses secure data encryption technology.

2. It allows business partners to access and share information electronically,

3. It enables employees to collaborate with each other by sharing information, and

4. It makes employees more efficient by creating a central repository for all of an organization’s documents and data which can then be shared easily with anyone in the organization as long as they have a username and password.


1. There is no way of telling whether someone has accessed or copied information from the intranet or internet, and the whole idea that it is private is open to interpretation by hackers.

2. Hackers could find the intranet, break into it and steal information.

3. The access to the intranet could be revoked by a hacker, denying legitimate users access.

4. Users could put confidential information on the intranet.

5. Users might not be able to control how secure the data is when it is being transferred from one computer system to another in their organization (for example information on an employee’s medical conditions, salary or bank details).  

6. If a user does not secure their login details and password, someone else may gain unauthorized access to it (e.g., if an employee flashes their login details in front of others or posts them online).

The term Internet is defined as the network of interconnected devices that provide connectivity using the Internet protocol suite (TCP/IP). The Internet can be accessed on a wide variety of devices, such as personal computers, smartphones and tablets, mobile phones and routers.

Advantages of Internet:

1. It provides instant information access to any device as long as it has a computer or smartphone with an internet connection.

2. The wide range of online applications available to users is made possible by the functionality of the Internet.

3. An individual’s identity is always up-to-date and visible because user accounts and web pages can be updated remotely or in real time.

4. The Internet can be used to share information, either locally or globally. A wide range of applications at the local and global level are possible.

5. The Internet makes all sorts of information, data or knowledge (e.g., medical records, banking details or personal notes) available to anyone with a computer and access to the internet.

6. It is a very efficient way of communicating with people around the world and anywhere in the world if they have access to it (mobile phones, iPads, laptops and desktops)

7. The Internet provides privacy because web pages can only be viewed by a specific user’s right password if they have access to that page via their computer or smartphone.

8. The Internet is used to share information quickly and easily and also to access information from any point in the world where a computer or smartphone with an internet connection is available.

Drawbacks :

1. The Internet is not private. It is fairly easy to find out where people are going on the Internet and what they are looking at and doing.

2. The Internet could be very expensive to use if necessary hardware is needed such as for high speed or secure access.

3. The value of some information may have to be protected from prying eyes through encryption technology or through security software (e.g., firewalls) that can be used to control access from strangers, hackers or others who may try to break the security system.

4. Web pages can be accessed by anyone with a computer who has Internet access from anywhere in the world even though it is normally only available in one country or territory.
