MSPs, Network Providers Face Rising Peak-Demand Resilience Tests

In 2025 two security incidents — a cyberattack that affected Marks & Spencer’s first-half results and a breach at Jaguar Land Rover that disrupted its supply chain — highlighted the risk of outages during busy trading periods. Customers are placing more responsibility on managed service providers (MSPs) and network firms to keep systems running and to coordinate recovery when problems occur.

Modern IT environments combine cloud platforms, internet-of-things devices, remote endpoints and real-time applications. A recent industry measure found 94% of private-sector IT leaders familiar with so-called smart spaces that link those elements. As systems become more distributed, network performance and security affect productivity, service delivery and customer experience across multiple sites and supply chains.

During seasonal peaks or unexpected surges, traffic can rise quickly and cloud services must scale in real time. Distributed workforces and a growing number of connected devices increase the demand for reliable access and enlarge the potential attack surface. When connectivity fails during high-demand periods, effects are immediate across retail operations, logistics and customer-facing systems.

Channel partners are taking on operational responsibilities beyond supplying services. Providers are offering scalable connectivity such as software-defined wide-area networking (SD-WAN) and high-capacity 5G to handle surges and provide failover when primary circuits degrade. High-capacity 5G is being used to support mobile point-of-sale terminals, digital signage and large numbers of IoT devices. SD-WAN can reroute traffic automatically to maintain performance. Some customers have consolidated network suppliers to simplify management and reallocate budget.

Security architectures are being updated to match network changes. Secure Access Service Edge (SASE) frameworks combine networking and security controls into a central model that governs access, identity verification and data protection. When SASE is combined with scalable connectivity, IT teams can enforce consistent security policies, detect threats faster and restore services with less manual coordination during busy periods.

Organisations are auditing networks to find capacity issues, latency bottlenecks and fragmented security policies. Centralized platforms for managing IoT and smart devices are being deployed to reduce operational complexity and limit unpatched vulnerabilities. The aim in these audits is to shorten the time between failure and recovery by improving visibility and assigning clear operational responsibilities to MSPs.

Customer expectations around service commitments have shifted. During peak trading periods, incident response and recovery plans are expected to be immediate and to minimize revenue loss and reputational damage. Delivering that level of readiness has required investments in automation, observability tools and joint security operations between providers and customers.

Network performance is being treated as a business asset tied to revenue and reputation. Organisations are investing in resilient, centrally managed connectivity and integrated security architectures to protect busy trading periods and to support future technology deployments such as expanded IoT implementations and artificial intelligence applications.
