Internet Versus Intranet

Internet Versus Intranet: What Do I Need To Know About The 2

As someone who has spent a fair amount of time working with both the internet and intranets, I know firsthand that there can be some confusion around the differences between the two. In this article, I’ll provide an overview of what you need to know about the internet and intranets, including their differences, advantages, and best practices.

Understanding the Differences between Internet and Intranet

Let’s start with the basics: what is the difference between the internet and an intranet? At a high level, the internet is a global network of connected devices and servers that allows for communication and information exchange across the world. In contrast, an intranet is a private network that is limited to a specific organization or group of individuals.

Accessibility is a key differentiator between the two. The internet is open and accessible to anyone with an internet connection, while intranets are typically password-protected and only accessible to authorized users. This is because intranets often contain sensitive information that should not be accessible to the general public.

Accessibility: Internet versus Intranet

The accessibility differences between the internet and intranets have significant implications for how they are used. For example, the internet is a great resource for research and public-facing communication, while intranets are typically used for internal communication and collaboration.

One advantage of intranets is that they allow for secure collaboration within an organization. For example, a company might use an intranet to share documents and communicate within teams, without having to worry about external parties gaining access to that information. In contrast, information shared over the internet is inherently less secure, as it is accessible to anyone with an internet connection.

Intranet Limitations: Access and Permissions

While intranets provide a more secure environment for collaboration and communication, their limited access can also be a drawback. For example, remote workers who are not on the company’s internal network may not be able to access the intranet, which can make collaboration more difficult.

Additionally, access and permissions must be managed carefully to ensure that only authorized users can access the intranet. This can be a challenge, particularly for large organizations with many users and departments.

Advantages of Using an Intranet over the Internet

Despite the limitations of intranets, there are several advantages to using them over the internet in certain contexts. One of the biggest advantages is that intranets can be customized to the specific needs of an organization. For example, a company might create a custom intranet portal that includes links to internal documents, calendars, and other resources that are relevant to employees.

Intranets can also provide a more streamlined experience for internal communication and collaboration. For example, a team might use an intranet to share files and communicate, without having to use separate tools like email and chat.

Security Measures: Internet vs. Intranet

Security is a crucial consideration when it comes to both the internet and intranets. However, the security measures required for each can differ significantly.

On the internet, security measures typically focus on protecting sensitive information such as credit card numbers and personal data. This often involves using encryption and other technologies to ensure that data is transmitted securely.

In contrast, intranets are typically designed with more comprehensive security measures in mind. This can include measures such as two-factor authentication, intrusion detection systems, and firewalls to prevent unauthorized access.

Connecting Intranet to the Internet: Implications

While intranets are typically private and not accessible to the internet, it is possible to connect an intranet to the internet. This can have both advantages and drawbacks.

One advantage is that it allows for greater flexibility in terms of collaboration and communication. For example, employees who are working remotely can access the intranet from anywhere with an internet connection, which can improve collaboration and productivity.

However, connecting an intranet to the internet also comes with risks. If not properly secured, an intranet that is accessible from the internet can be vulnerable to hacking and other security threats. As such, it’s important to carefully consider the risks and benefits before making the decision to connect an intranet to the internet.

Common Uses of Intranet in Business and Organizational Settings

Intranets are widely used in business and organizational settings for a variety of purposes. Some common uses include:

  • Document sharing and collaboration: Teams can use the intranet to share documents and collaborate on projects in a secure environment.
  • Internal communication: Intranets can be used for internal communication, such as sharing news and announcements, company policies, and employee directories.
  • Knowledge management: Intranets can be used to store and share knowledge resources such as training materials, best practices, and procedures.
  • Workflow management: Intranets can be used to manage workflows and processes such as approvals and request forms.

Bandwidth Availability: Intranet versus Internet

Bandwidth availability can be a concern when it comes to using either the internet or intranets. In general, intranets can have faster and more reliable speeds than the internet, as they are not subject to the same network congestion that can occur on the public internet.

However, the bandwidth available for an intranet can still be limited by factors such as network infrastructure and the number of users accessing the network at once. As such, it’s important to carefully manage bandwidth usage to ensure that it is being used effectively.

Legal and Regulatory Considerations for Intranet Setup

When setting up an intranet, there are several legal and regulatory considerations that must be taken into account. For example, data privacy laws such as the General Data Protection Regulation (GDPR) in the European Union may require certain measures to be taken to ensure that sensitive data is being protected.

Additionally, there may be industry-specific regulations that need to be followed. For example, in the healthcare industry, intranets may need to comply with the Health Insurance Portability and Accountability Act (HIPAA) to protect patient data.

Best Practices for Managing and Maintaining an Intranet

Finally, it’s important to consider best practices for managing and maintaining an intranet. Some key tips include:

  • Regularly update software and security measures to ensure that the intranet is secure.
  • Assign clear roles and responsibilities for managing the intranet.
  • Monitor bandwidth usage to ensure that it is being used effectively.
  • Regularly review user access and permissions to ensure that only authorized users can access the intranet.

By following these best practices, organizations can ensure that their intranets remain secure and effective tools for collaboration and communication.


What is the main difference between the internet and an intranet?

The main difference is that the internet is a public network that anyone can access, while an intranet is a private network that is only accessible to authorized users within an organization.

Can an intranet be accessed from outside the organization?

An intranet can be accessed from outside the organization, but only if it is set up to allow remote access through a virtual private network (VPN) or other secure connection.

How can an organization decide whether to use an intranet or the internet for a particular task?

Organizations should consider factors such as the sensitivity of the information being shared, the number of users who need access, and the level of security required when deciding whether to use an intranet or the internet for a particular task.

What are some common security risks associated with intranets?

Some common security risks associated with intranets include unauthorized access, data breaches, and malware infections.

How can an organization ensure the security of its intranet?

Organizations can ensure the security of their intranet by implementing strong security measures such as firewalls, antivirus software, and user authentication protocols. Regular security audits and updates should also be conducted to identify and address any vulnerabilities.


In conclusion, the internet and intranets are both valuable tools for communication and collaboration, but they serve different purposes and come with their own unique advantages and limitations. By understanding the differences between the two and implementing best practices for managing and maintaining an intranet, organizations can effectively leverage these tools to improve productivity and collaboration.
