Explaining SD-WAN For Beginners

SD-WAN stands for Software-defined Wide Area Network. Referring to a type of network connection.

Organizations will opt to use SD-WAN to facilitate data sharing between various geographical locations. Rather than being connected by connectors like routers and switches, WAN connections are virtual connections that can include cloud applications and VPNs.

Software-defined networking (SDN) specifically approaches networking by optimizing software-based controllers or application programming interfaces (APIs).

Key Features Of SD-WAN

SD-WAN is a popular choice for digitally connected organizations that are widespread and rely on connectivity to communicate and share resources and information.

In a digitally transforming world, SD-WAN sets the standard for connectivity, bringing together devices located in different locations, playing a key role in the globalization of the world of work and the growth of individual businesses.

The key features of SD-WAN include:

Geographical coverage: SD-WANS are capable of connecting various locations spread across different geographical areas. This includes sharing information from one main office to another mile apart.

Simplifies WAN: Enhancing the traditional WAN connectivity, SD-WAN utilizes cloud-based applications such as Office 365 hosted in data centers. Delivering security, reliability, and enhanced productivity within businesses, across multiple teams and users,

Makes managing IT infrastructure easier: Implementing an SD-WAN helps organizations take full control of their firewalls, VPNs, and remote clients. All are monitored and managed on one interface.

Advanced security features: With the ever-growing number of cyber attacks posing a huge threat to large organizations and businesses in the ownership of sensitive data, an SD-WAN offers several advanced security features.

Offer protection against cyber threats and allow for the easiest and safest way to share data and communications.

The Benefits Of SD-WAN For Large Organisations

Improved security

One of the key reasons that an organization will implement SD-WAN connectivity is due to the enhanced security features it can provide. Offering a high level of cyber security that is imperative for the safe transfer of data and information between locations and users spread around the world.

By improving security with features like firewalls and VPNs, organizations can prevent the risks associated with cyber-attacks and security breaches such as loss of earnings, costs to rectify cyber attacks, downtime, and legal issues.

Savings in operating costs 

Another key reason for the use of SD-WAN across large businesses is the savings it promises in operational costs.

Where multiple IT teams are currently required to manually complete maintenance tasks and testing, SD-WAN can automate these processes, removing the need for such tasks to be passed onto IT teams or external IT teams that may be charging your business high fees.

Increased visibility and centralized management

SD-WAN provides comprehensive visibility into network traffic and performance. This allows IT administrators to identify and resolve problems quickly and proactively. Helping to improve the efficiency of your IT management.

While a single management portal centralizes the management of applications and network performances. Helping to reduce issues and simplify the process for IT management teams.


Since it is so visible and easy to manage, SD-WAN is also capable of scaling up or down depending on the business requirements. This means being able to adjust according to the demands of network traffic. This is the best solution for companies experiencing steady or fast-paced growth.
