IT complexity slows digital transformation as half of UK technology leaders warn network outages threaten revenue

Our latest research reveals that almost four in five (78%) technology leaders say technology complexity is slowing change, with multiple vendors, platforms and contracts significantly or extremely slowing down change in their IT environment, making transformation harder to deliver.

More than half (51%) of UK technology leaders say network resilience is business critical, and outages would have a significant impact on revenue, operations or customers. And 94% say network resilience is important to their organisation’s success.

The findings highlight why technologies such as SD-WAN are becoming increasingly important for organisations looking to modernise their networks. They also suggest network resilience is increasingly a leadership issue rather than simply an IT concern, with respondents linking outages to revenue, customer experience and operational performance.

Complexity is delaying technology decisions

Despite recognising the importance of resilient networks, many organisations are struggling to make progress. Almost half (49%) of technology leaders say the biggest barrier preventing longer-term technology decisions is a lack of buy-in from leadership outside IT.

Organisations still intend to invest. More than a third (36%) say network modernisation and connectivity will be among their biggest technology investments over the next three years. However, the findings show why many are struggling to make that progress:

• 47% say multiple suppliers delay projects and complicate change
• 31% say they consistently slow or block change

Simplifying the path to resilient growth

Jon Nowell, Managing Director of our Business division, explains why organisations need a simpler approach to networking and security:

Businesses no longer question whether resilient networks matter. Outages and cyber threats directly threaten revenue, yet most organisations are still battling complex technology environments that slow progress. SD-WAN, combined with a SASE approach to networking and security, offers a way to simplify connectivity, strengthen protection, improve resilience and support future digital transformation.

Too many organisations are spending valuable time managing multiple suppliers, disconnected systems and separate security solutions when they should be focused on innovation and delivering value to customers. The challenge isn’t simply keeping businesses connected. It’s giving them the confidence that their network can support growth, cloud adoption, AI initiatives and new ways of working, while ensuring users, applications and data remain secure without adding more complexity.

Organisations don’t need more technology to manage, they need technology that reduces complexity. A fully managed Zen SD-WAN service with integrated security and a clear path to SASE helps create a resilient network that’s easier to operate today and ready for tomorrow.
