Introduction: Explaining SD-WAN and VPNs
When it comes to connecting to the internet, there are two options to consider- SD-WAN and VPNs. At their core, they both have the same purpose – linking you to a remote network that isn’t directly in front of you.
What is SD-WAN?
SD-WAN stands for Software Defined – Wide Area Network. SD-WAN allows secure connections to branch offices, cloud services and data centers anywhere in the world. Also, SD-WAN simplifies the management and operation of WAN by removing the dependencies on old technologies.
What is a VPN?
VPN stands for Virtual Private Network, which is an encrypted internet connection that helps to secure sensitive data transmissions. VPN employs a tunnel-like encrypted environment provided by internet service providers to users.
While technically different, both technologies aim to transmit data securely from one place to another that is not on the current network.
Hopefully now you have a better understanding of these two technologies. Before deciding between the two we must deeply explore them individually and look at the advantages they each provide when it comes to security and performance.
Definitions: Define SD-WAN and VPNs in detail
If you’re not familiar with the terms, SD-WAN and VPN might sound like complex technical jargon. But once you understand them, you’ll see they are actually quite simple.
What is SD-WAN?
SD-WAN stands for Software-Defined Wide Area Network. In essence, it’s a way to connect multiple locations and devices over a network. With SD-WAN, network traffic management and security functions are separated from the physical connections between devices and moved into the cloud. This shift provides more flexibility and control when managing network traffic for an organization.
It allows for direct internet access, bypassing any potential networking limitations.
SD-WAN helps minimize IT complexity by reducing hardware requirements that comes with secure networking.
The lightweight client is easy to deploy and costs far less than traditional branch office router without compromising on features and performance.
What is VPN?
The term VPN stands for Virtual Private Network. A VPN creates a secure, encrypted connection between two or more devices over the public internet. Through this tunnel, data can be transmitted securely and in a manner consistent across all platforms. When using a VPN, it’s as if the computers involved are physically located in the same place despite being even continents apart. Commercial VPNs are heavily utilized for protection of critical informations.

Generally speaking, the implementation and ongoing maintenance costs of SD-WAN can be higher than VPNs. This is because SD-WAN often uses more complex hardware solutions, and may require more specialized expertise to set up and manage effectively.
On the other hand, VPNs tend to be a more established technology, meaning that the costs of setting up and maintaining a VPN connection can often be lower. However, there are a few important caveats to consider.
Firstly, establishing a VPN connection can involve significant upfront costs, particularly if you need to purchase custom hardware or other essential components. Additionally, as VPN usage grows, users might run into various costs for additional setup, admin tools, and scale their VPN use. In some cases, routing through multiple VPN connections, logging multiple log files / hosts may create traffic monitoring problems than only an SD-WAN can mitigate.
Secondly, although VPNs have low costs per transaction, it can cause performance degradation due to overcrowding or other limitations only an SD-WAN can minimize._
In terms of ongoing costs, another significant factor to consider is the cost of bandwidth. VPNs are likely to add overhead costs since data runs to encryption via VPNs. While SD-WAN offers more extensive links, optimizing network management paths without encryption duplications, saving operations costs and significantly reducing overall WAN costs in some cases. Whereas, VPNs do not create similar networking opportunities.
Another point to consider is scalability. As businesses grow and their bandwidth needs increase progressively, SD-WAN becomes more affordable when providing economically sorted VNFs at high speed. Although VPN of today can cover relatively larger WAN needs, as monitoring complexities arise they can cause further overhead costs.
Of course, such issues will vary depending on the specific needs of your business network, connection structure and systems.
