As organisations of all sizes continue to adapt to a digital-first world, the way networks are designed and managed has come under increased scrutiny. With more employees working remotely, more services moving to the cloud, and more applications requiring real-time responsiveness, the demands placed on traditional networks have grown beyond their original capacity.
In this evolving landscape, software-defined wide area networking, or SD-WAN, has emerged as a modern alternative to conventional WAN architecture. More recently, the option to outsource the design, deployment and ongoing support of SD WAN to external experts – known as managed SD WAN providers – has become an increasingly attractive proposition for businesses looking to simplify network complexity and focus on core priorities.
This article explores what managed SD WAN providers offer, why the demand for their services is growing, and how businesses can benefit from this model.
What Is SD WAN?
To understand the role of managed SD WAN providers, it is helpful to first clarify what SD WAN is. In simple terms, SD WAN is a virtualised network architecture that allows organisations to use multiple forms of connectivity, such as broadband, fibre, and 4G or 5G, in a more flexible and intelligent way.
Unlike traditional WANs, which typically rely on rigid configurations and dedicated circuits such as MPLS, SD-WAN routes traffic based on real-time performance. It can automatically direct critical applications over the most reliable connection, adjust traffic flows based on demand, and provide greater visibility into network activity.
The result is a network that is more responsive, more cost-effective, and easier to manage, especially for organisations with multiple sites, remote teams, or significant cloud dependency.
The Challenge Of Managing SD WAN In-House
Although SD WAN offers a long list of benefits, it also introduces new layers of complexity. Deploying SD WAN at scale requires an understanding of network configuration, security policies, quality of service requirements, and performance monitoring.
For businesses without a dedicated IT team – or even those with a small in-house team – managing all of this internally can be both time-consuming and challenging. The technology is relatively new compared to legacy networks, and the skillset required to manage SD WAN effectively may not be available in-house.
That is where managed SD WAN providers come in.
What Do Managed SD WAN Providers Do?
Managed SD WAN providers deliver SD WAN as a fully supported service. Instead of simply selling the technology and leaving the client to manage it, these providers take full responsibility for designing, deploying, and maintaining the network.
Their services typically include:
- Initial consultation and network assessment: Understanding the organisation’s current setup, challenges, and objectives.
- Solution design and vendor selection: Choosing the right SD WAN technology and configuration for the business needs.
- Implementation and migration: Seamlessly transitioning from the existing infrastructure to the new SD WAN environment with minimal disruption.
- Ongoing monitoring and optimisation: Proactively managing the network to ensure consistent performance and reliability.
- Security integration: Ensuring that the SD WAN environment aligns with cybersecurity policies and protects against modern threats.
- Support and maintenance: Providing technical support and updates as part of an ongoing service agreement.
In short, they take the operational burden off the client’s shoulders and allow internal teams to focus on strategic goals instead of network maintenance.
The Benefits Of A Managed Approach
There are several reasons why businesses choose to work with managed SD WAN providers, particularly in industries where reliable connectivity is crucial.
1. Expertise Without Hiring
One of the biggest advantages is access to specialised knowledge without needing to build that capability in-house. Managed providers have experience across multiple industries, network types, and deployment scenarios, meaning they can identify best practices and avoid common pitfalls.
2. Faster Time to Value
Because these providers handle the entire process from planning to implementation, businesses can benefit from a much quicker deployment. What might take months of research and training internally can often be delivered in weeks by a managed provider.
3. Improved Performance and Resilience
By intelligently routing traffic and using multiple connections, SD WAN can reduce latency, prevent outages, and improve the overall user experience. With proactive monitoring from a managed provider, potential issues can be identified and resolved before they become major problems.
4. Better Use of Internal Resources
For many organisations, the internal IT team is already stretched thin. Offloading SD WAN to an external partner means they can focus on more strategic projects rather than reacting to network issues or learning a new technology from scratch.
5. Cost Predictability
A managed service model typically involves a monthly or annual fee, which can make budgeting more straightforward. It also avoids the surprise costs that can come with unexpected outages or emergency upgrades.
What to Consider When Choosing a Provider
Not all managed SD WAN providers offer the same level of service, and the right choice will depend on your organisation’s needs and goals. Some important questions to ask include:
- Do they offer 24/7 support?
- Are they technology agnostic or tied to a single vendor?
- Can they scale as your business grows or changes?
- How do they handle security and compliance?
- What level of visibility and reporting do they provide?
It is also worth considering whether the provider understands your industry and can tailor the solution accordingly.
A Strategic Move For A Cloud-First World
As businesses continue to embrace cloud applications, hybrid working, and digital transformation, network infrastructure must evolve to keep up. SD WAN offers a flexible and modern solution to these demands, but managing it internally may not be practical for many organisations.
That is why the role of managed SD WAN providers is becoming more prominent. By offering a full-service model, they enable businesses to access the benefits of SD WAN without the complexity or resource strain of doing it alone.
For those looking to modernise their network, improve resilience, and support digital growth, managed SD WAN is a smart step forward.
