Wide Area Networks

9 Things You Must Know about Wide Area Networks (WANs)

Wide area networks (WANs) are large-scale networks that span multiple geographic regions. They connect different parts of an organization, such as two offices in other cities or various organizations, such as two schools in different states. WANs provide much-needed connectivity in today’s increasingly complex and mobile world. 

Here are nine key points you should know about WANs as part of network security services:

1. WANs Utilize Different Types of Connectivity

WANs can use various types of connectivity to link different locations. These include fiber optic cables, satellite links, and copper wires. Each type of connection provides different benefits, so choosing the right style for your organization’s needs is essential.

2. WANs Have Higher Bandwidth Than LANs

WANs have significantly higher bandwidth than local area networks (LANs). This allows them to transfer more data over longer distances. Also, this makes them well-suited for transmitting large amounts of data, such as video and audio.

3. WANs Are More Expensive Than LANs

WANs are typically more expensive than LANs because they require more specialized equipment and services. Setting up a WAN can be prohibitive for some organizations, but it is often necessary if they need to connect multiple locations.

4. An ISP Usually manages WANs

An internet service provider (ISP) usually manages and maintains WANs. This means the organization does not have to manage and maintain the network. This can benefit organizations that need more expertise or resources to manage their networks.

5. WANs Can Be Vulnerable to Security Issues

As WANs span multiple locations, they can be vulnerable to security issues. It is vital to ensure that all network elements are securely configured and monitored to prevent unauthorized access. Additionally, all traffic should be encrypted to avoid any data from being intercepted.

6. WANs Can Be Public or Private

A WAN can be either public or private. A public WAN uses the public internet to connect devices, while a private WAN uses dedicated leased lines. Private WANs are generally more secure and reliable than public WANs but are also more expensive.

7. WANs Can Be Complex

WANs can be very complex and require expertise to set up and maintain. It is vital to have a solid awareness of networking technologies and protocols to ensure that the WAN is configured correctly and is operating optimally.

8. WANs Are Scalable

WANs are very scalable, allowing businesses to add more locations and devices as their needs grow. This scalability makes them ideal for companies with many sites that need to connect them easily.

9. WANs Can Increase Efficiency

WANs can increase efficiency in a business by allowing multiple sites to access the same resources and communicate with each other quickly and securely. With the assistance of network security services, your WAN can reduce costs and improve the business’s overall productivity.


Understanding these five key points enables you to make an informed decision when selecting a WAN for your organization. WANs are an essential part of many organizations and can provide valuable connectivity and data transfer capabilities.
