In the rapidly evolving world of manufacturing, the factory floor is no longer a collection of isolated machines and manual processes. Today’s factories are dynamic, highly connected environments where data flows as freely as raw materials. This transformation is being driven by the convergence of operational technology (OT) and information technology (IT), the rise of Industry 4.0, and the need to remain competitive in a global market. For IT managers, the challenge is clear: how do you build a digital backbone that is not only robust and secure but also agile enough to support innovation and growth?
This is where the combination of a strong IT infrastructure and co-managed SD-WAN (Software-Defined Wide Area Network) becomes essential. In this article, we’ll explore why investing in these technologies is no longer optional, how they address the unique challenges of manufacturing, and why a co-managed approach can unlock even greater value for your business.
The New Digital Backbone: Why Infrastructure Matters More Than Ever
Manufacturing is undergoing a profound digital transformation. Concepts such as smart factories, digital twins, predictive analytics, and collaborative robots are no longer futuristic visions—they are becoming standard practice. According to the World Economic Forum, smart factories are at the heart of this revolution, enabling manufacturers to achieve new levels of efficiency, flexibility, and quality.
However, these advances come with new demands on IT infrastructure:
-
Real-time Data: Modern manufacturing relies on a constant stream of data from sensors, machines, and enterprise systems. This data must be collected, analysed, and acted upon in real time to optimise production and prevent issues before they escalate.
-
Connectivity: With factories often spread across multiple locations and supply chains extending globally, reliable and high-speed connectivity is a must. Any interruption can halt production lines, delay shipments, and erode customer trust.
-
Security: As manufacturing systems become more interconnected, the risk of cyberattacks increases. The manufacturing sector is now one of the most targeted industries for cybercrime, making robust security measures essential for protecting intellectual property and operational continuity.
-
Scalability: The pace of innovation means that IT infrastructure must be able to scale quickly to support new technologies, additional sites, and increased data volumes.
A modern digital backbone addresses these challenges by providing a resilient, secure, and scalable foundation for all digital initiatives. This includes not just the physical network and servers, but also cloud integration, edge computing, and advanced analytics capabilities.

The Role of Co-Managed SD-WAN in Modern Manufacturing
While a robust infrastructure is the foundation, managing the complexity of modern manufacturing networks requires a smarter, more flexible approach. This is where SD-WAN comes in.
SD-WAN is a technology that simplifies the management and operation of a wide area network by separating the networking hardware from its control mechanism. It enables organisations to dynamically route traffic across multiple types of connections—such as fibre, broadband, 5G, and MPLS—based on real-time conditions and business priorities.
But what does “co-managed” mean? In a co-managed SD-WAN model, your internal IT team works in partnership with a specialist provider like Digital Carbon. This shared responsibility model gives you the best of both worlds: centralised control and visibility, combined with expert support for day-to-day management, security updates, and troubleshooting.
According to Gartner’s SD-WAN Market Guide, SD-WAN adoption is accelerating in manufacturing as companies seek to improve network agility, reduce costs, and enhance security.
Simplifying Security Across the Factory
Security is a top concern for every IT manager in manufacturing. With the blending of IT and OT, the attack surface has expanded, and traditional security models are no longer sufficient.
Co-managed SD-WAN addresses this by:
-
Centralising Security Management: Policies are enforced consistently across all sites, reducing the risk of misconfigurations and gaps.
-
Enabling Network Segmentation: You can create secure zones for different parts of your operation, isolating critical assets and limiting lateral movement in the event of a breach. This aligns with standards like IEC 62443, which are becoming increasingly important in industrial environments.
-
Supporting Zero Trust Principles: Every user and device must be authenticated and authorised, minimising the risk of unauthorised access.
-
Providing Secure Remote Access: As remote monitoring and third-party vendor access become more common, SD-WAN offers encrypted, application-aware tunnels that are far more secure than traditional VPNs.

Enhancing Resilience and Uptime
Downtime is the enemy of manufacturing. According to Forbes, unplanned downtime can cost manufacturers millions in lost productivity, wasted materials, and missed deadlines.
Co-managed SD-WAN enhances resilience by:
-
Providing Redundant Connectivity: If one connection fails, SD-WAN automatically switches to a backup, ensuring continuous operations.
-
Dynamic Path Selection: The system monitors network performance in real time and routes critical applications over the best available path, maintaining high-quality voice, video, and data communications.
-
Automatic Failover: In the event of a network issue or cyber incident, SD-WAN can instantly reroute traffic to backup connections, minimising disruption to production lines and supply chain systems.
-
Integrated Security During Failover: Security policies and encryption remain enforced even during failover events, ensuring that resilience does not come at the expense of security.
Streamlining Operations and Enabling Growth
Operational efficiency is another major benefit of co-managed SD-WAN. With a single dashboard, IT managers can oversee all sites, deploy updates, and respond to issues quickly—no matter where they occur. This centralised visibility not only saves time but also helps you spot trends, optimise bandwidth, and plan for future growth.
-
Operational Simplicity: Routine network management is handled by experts, freeing your team to focus on strategic projects.
-
Real-Time Visibility and Analytics: Comprehensive monitoring tools allow you to track application performance, bandwidth usage, and security events across all locations.
-
Seamless Integration with Cloud and Edge: SD-WAN is designed to support cloud-based applications, edge computing, and IoT devices, allowing manufacturers to scale digital transformation initiatives without network bottlenecks.
-
Continuous Improvement: Co-managed models often include regular workshops and training, ensuring that IT staff are upskilled in policy creation, threat hunting, and compliance reporting, while benefiting from the provider’s ongoing innovation and best practices.
