The benefits of SD-WAN over traditional WAN architectures
The traditional hub and spoke model was predominant before the widespread use of SD-WAN. In a traditional model, to move data from the cloud, the data has to move to the data centre and then to the final destination. On the contrary, in the case of SD-WAN, Points of Presence or PoPs are distributed in the data centres across the globe, facilitating the transfer of data without routing through the data centre.
Before discussing whether SD-WAN is beneficial over traditional WAN architecture, let us understand both concepts.
Traditional WAN
Several LANs located at different geographical locations are connected with one another in traditional networking. Traditional WAN connects branch offices and remote offices to the centralised network to access applications, share data and perform business functions. Conventional WAN was seen as a reliable means to deliver data, but as the business expands across geographical boundaries, the data has to travel through multiple carriers. This could lead to network congestion, packet loss, call drops, etc. Moreover, each and every server and router must be updated every time a change in policy occurs due to its distributed nature. User experience is compromised when streaming HD videos, virtual reality or during video conferencing.
SD-WAN
SD-WAN connects hardware from various locations. Different connections are used for transporting data, including private lines, Virtual Private Networks or VPNs, Multiprotocol Label Switching (MPLS), broadband and LTE. SD-WAN finds the most efficient route to transport the data, whereas traditional WAN architecture uses corporate data centre connections to route the data.
Types of SD-WAN Architecture
Enterprises can opt for three types of architecture, on-premises SD-WAN, cloud-enabled SD-WAN, and cloud-enabled with backbone SD-WAN.
On-Premises SD-WAN: It is a plug-and-play SD-WAN box that can be installed on your premises or onsite. It does not connect to the cloud gateways but uses company connections.
Cloud-enabled SD-WAN: This configuration uses both software and hardware. It uses an onsite SD-WAN device and connects to the virtual gateway. In turn, the gateways are connected to the cloud providers like Microsoft Office 365, AWS, Azure, DropBox and Salesforce.
Cloud enable plus backbone: Sometimes issues arise while using the internet with SD-WAN, to avoid this snag, backbone is used. It connects the enterprise premises to the cloud PoP and from here the traffic is diverted to the private fibre optic network backbone. The low latency private backbone results in minimum packet loss and jitters.
Why is SD-WAN better than traditional WAN?
Thanks to the internet, businesses are transforming faster as the world is shrinking. The Pandemic has forced us to work from remote locations, and SD-WAN perfectly fits in this space. Let’s see why SD-WAN is better than traditional WAN.
- Traditional WAN allows prioritisation and traffic predictability but at a high cost. On the contrary, SD-WAN cuts down on internet costs, and users must spend big money on bandwidth upgrades. SD-WAN offers flexible network connectivity as it can run both on LTE and broadband. SD-WAN is affordable and allows app prioritisation without any packet loss.
- Traditional WAN is private and allows secure communication. In comparison, SD-WAN offers end-to-end encryption across a VPN connection with an option to add and merge additional security layers, such as firewalls, for unified threat management.
- In traditional WAN, changes must be configured manually due to their distributed nature. In SD-WAN, you can scale as your business grows. Just leave it to your managed service provider, and they will do the rest.
SD-WAN is a reliable way to receive and deliver network services to your organisation. Though, some organisations adopt hybrid WAN. An organisation should select the appropriate network based on the long-term and short-term objectives in mind. Since each organisation has unique requirements, there is no one size fits all concept. You all require a skilled workforce for maintaining and managing network services. If you are ready for a change, then train your network professionals in SD-WAN for a seamless transformation.

How SD-WAN is transforming network security: Zero-trust architecture and more
Businesses are expanding into new geographical boundaries, increasing the need for a hybrid IT environment. The traditional network infrastructure is choking under pressure, unable to match the growing demands. The need for multiple sources has resulted in the growth of Software Defined Wide Area Network (SD-WAN) technology.
Can SD-WAN transform network security?
SD-WAN promotes secure vendor and agnostic data transport across WAN or internet connectivity increasing hybrid cloud adoption. SD-WAN can aggregate multiple network technologies like MPLS, broadband, LTE, and 5G to connect to branches and remote offices. Compared with MPLS, SD-WAN is 2½ times cost effective due to secure edges, limited staff and router service costs.
Security is the top priority in SD-WAN. Organisations are keen on understanding the security impacts of installing SD-WAN as it should not expose the network to vulnerabilities while connecting to the cloud or embracing new endpoints. In an Enterprise Management Associates (EMA) report, respondents placed security on the top in SD-WAN.
Zero Trust Model in SD-WAN
The security of SD-WAN increases with Zero Trust Model. So, what is Zero Trust Model? It is the security feature that stops trusting applications, networks, users or devices by default and introduces a host of verifications. In this model, authentication is given priority, followed by network security.
A secure SD-WAN architecture promotes agility and performance of your WAN network by establishing security-rich features that can be embraced with your present infrastructure. For on-premises to cloud end-to-end circuit encryption, the model uses IPSec 256-bit protection. The model assists IT managers to monitor and control the access points on the application and network. Firewalls and edge devices must be deployed for foolproof security.
How can the zero trust model replace traditional WAN?
SMOAD SD-WAN enabled security and performance, helping save money. It encompasses all security SD-WAN solutions an organisation seeks. Zero trust principles are brought to every connectivity and not just users. All IoT/OT devices and servers are brought under the ambit of the model. It eliminates any threats and surface attacks using a router WAN network. Now you can convert your branch offices into modern branches using SaaS and cloud app deployments. Automated and integrated connectivity can reduce internet outbreaks and provides smarter and faster service.
New architecture needs new security with transactions moving to the cloud and internet; there is a need for a highly secure environment to protect distributed users from the vulnerabilities of attack. Today, applications, data and devices are moving out of the perimeter of security as they breach the traditional line of control. As the trusting enterprise perimeter is violated, there is a need for modern defence strategies for distributed workforces. It is here that the Zero Trust Model comes into play. Some of the tenets of this model include:
- Securing resources and accesses irrespective of hosting model or location
- Adopting default deny strategy while establishing application access
- Traffic logging and inspection for applications you control and don’t in order to monitor any malicious activity.
Zero Trust Security components
The Zero Trust Security components include:
- Secure Internet Gateway (SIG): The ultimate idea of Zero Trust security is to protect the user while accessing applications beyond your control. A simple click can unleash cyber threats on your connectivity. With remote offices set in, the devices are unmanaged, and the internet is the choice of the corporate network. SIG is simple, quick and cheap while securing Direct Internet Access (DIA) traffic. SIG is safe, as it proactively protects users irrespective of location. Every DNS request is inspected, and malicious domains are blocked.
- Identity Aware Proxy (IAP): The architecture provides application access through a cloud-based proxy. In this architecture, identity and authorisation happen at the edge and are only on a need-to-know basis. It uses standard HTTPS protocol at Layer 7 or the application layer. IAP identifies the source and verifies the user and device trust. It checks the security criteria like certification, password protection, endpoint direction, response solutions and installation of the latest OS. The user traffic is inspected, and any application request can be examined, authorised and terminated. After terminating the transaction on the proxy, additional features are integrated for better user experience and protection of the application.
Transform your business into a modern network model by protecting the line of defence. SMOAD believes SD-WAN with Zero Trust Security is the initial step to moving to a safe and threat-free internet.

SMOAD SD-WAN AND THE INTERNET OF THINGS (IOT): ENHANCING CONNECTIVITY AND CONTROL
There’s no denying that SD-WAN has indeed enhanced the quality of connectivity and the business application experience. The continued evolution of SD-WAN has also enabled enterprises to take advantage of new customised IoT devices. The health industry greatly benefits from remote monitoring systems that report a patient’s vital signs to medical care providers within seconds. Retail stores can now automatically alert their warehouses with the list of products that need replenishment. The magnitude of IoT has constantly been on the rise since its creation, and it is estimated that the size of IoT gadgets may reach 500 billion by the end of 2030. Thanks to SD-WAN-enabled IoT! Flexibility, centralised management, and high security offered by SD-WAN solutions have enabled IoT devices to perform better and be more productive.
Networking Challenges Faced by IoT
Low-latency connectivity, high cost, and poor management of IoT applications spread across multiple locations are the major challenges faced by IoT applications. Let’s take the surveillance camera, for example – the considerable quantity of data that public surveillance cameras transfer can overwhelm the traditional WAN network connections.
You need a solution that prioritises traffic and chooses the right WAN path according to the quantity of traffic transferred. Software-defined WAN (SD-WAN) does the same and streamlines connectivity effortlessly and cost-effectively.
Security is another great challenge faced by IoT applications. Developers usually leave backdoor access open for further development purposes. This makes IoT devices vulnerable to hacks and cyber-attacks. SD-WAN offers advanced security functionalities, and since it can be easily integrated with new devices, security-related challenges can be overcome with ease.
Why is SD-WAN considered the Key Enabler of IoT
By now, you might be aware that SD-WAN offers flexibility which is much needed for the smooth running of numerous IoT devices connected over a wide range of networks. Besides that, it also makes the management of distant IoT applications easy. This is possible because SD-WAN can adapt to devise necessity and application requirements.
Here’s how SD-WAN plays an essential role in simplifying IoT management:
1) Reduces Complexity
IoT devices rely on a range of connections, including wireless, mobile, wired, static, and even cellular. Each connection has its speed, protocol, and agility. While some IoT devices may run on a specific type of connection, most others rely on a combination of one or more connectivity options. This can complicate the connectivity process and pose challenges when it comes to troubleshooting or ensuring a consistent performance from the IoT device.
SD-WAN does away with this complexity by enabling the combination of a range of connections into one hybrid network. SD-WAN allows management of the network from one interface and also makes routing decisions while trying to prioritise traffic.
2) Enhances Security
As mentioned earlier, IoT devices are subject to hacks and attacks. The developer may leave endpoints open for further developmental processes, and these endpoints ultimately serve as vulnerable loopholes for hackers. Improper penetration testing of IoT applications can be another reason IoT devices suffer security issues.
SD-WAN offers high-quality security features through fine-grain segmentation of WAN. Through fine-grain segmentation of WAN, IoT devices are isolated or detached from the rest of the network, thus preventing hackers from accessing extremely secure and sensitive information. Moreover, SD-WAN also enables the virtualisation of security services so that they are deployed across a range of networks in a software format.
3) Enhances Network Visibility
Real-time visibility is another challenge faced by IoT devices dependent on a spectrum of connections. Poor visibility results in the inability to identify the performance attributes of the IoT devices. This could prevent an information officer from gaining access to important metrics and ultimately result in poor device performance.
Most service providers offer SD-WAN solutions embedded with real-time visibility functionality that allows capturing the application and network performance in real-time. Even data such as the total bandwidth consumed by the IoT device can be captured using this functionality. This data can further be used to troubleshoot existing application issues or eventually enhance the device’s performance.
Adopting SD-WAN for your business can provide uninterrupted connectivity keeping your IoT devices on the toe round the clock. For more information on SD-WAN for your IoT devices, contact SMOAD.
