Top 5 networking trends to watch in 2025

Predicting the future of networking technology is inherently challenging. Innovations that appear groundbreaking today can quickly lose relevance, while other slow-burn trends may suddenly explode into prominence. No-one can claim to have a crystal ball. 

Networking, as a cornerstone of digital transformation, is no exception. Many predictions I have encountered for 2025 highlight technologies still maturing or years away from widespread adoption. Instead, I will focus on enterprise networking trends that have built a solid foundation and are ready to take centre stage. For this, I have leaned on insights from Gartner’s Hype Cycle for Enterprise Networking, 2024. 

In this year’s Hype Cycle, five technologies stand out. These are expected to reach the plateau of productivity in less than five years. Here’s why I believe they will be pivotal in 2025. 

1. SD-WAN adoption to increase 

SD-WAN (Software-Defined Wide Area Networking) has steadily gained momentum, but 2025 could mark a tipping point for its adoption. Why?  

Organisations are under increasing pressure to enhance their network flexibility while controlling operational costs. 

SD-WAN provides flexible, secure, and scalable connections by leveraging long-term evolution (LTE) and broadband internet, significantly reducing reliance on costly MPLS (Multiprotocol Label Switching) circuits. 

According to TeleGeography, the WAN market is projected to hit $85 billion among the world’s 5,000 largest companies by 2026, representing a 44% growth over 2021. This surge underscores SD-WAN’s growing role as a cornerstone of enterprise networking strategies. 

2. Microsegmentation 

The need for robust cybersecurity solutions continues to escalate, especially with the rise of hybrid work and increasingly sophisticated threats. Microsegmentation offers an elegant and effective response to this challenge. 

Microsegmentation divides a network into smaller, isolated segments, making it far more difficult for attackers to move laterally within an organisation’s IT infrastructure. It enhances security by focusing on protecting individual workloads and devices, enforcing granular access controls, and ensuring that traffic between segments is tightly controlled. 

3. Secure Access Service Edge (SASE) 

SASE is rapidly emerging as a critical framework for modern networking, driven by the growing importance of cloud and edge computing. It combines networking and security into a unified, cloud-native architecture, addressing the challenges of managing diverse environments in a mobile-first, cloud-centric world. 

SASE is particularly significant for organisations with dispersed workforces and hybrid infrastructure. It simplifies network management while delivering consistent security policies across applications, users, and devices, regardless of location. 

4. Multicloud networking software  

Companies no longer rely on a single cloud provider; instead, they are embracing a multicloud approach to optimise costs, improve redundancy, and avoid vendor lock-in. 

Multicloud networking software is vital for enabling seamless connectivity, consistent performance and simplified management across diverse cloud environments. It ensures that applications and workloads perform optimally regardless of their cloud location. 

As organisations strive for agility, scalability and operational efficiency, multi-cloud networking will play a central role in helping them achieve these goals. 

5. 5G will continue to evolve as a game changer 

While 5G is still in the “trough of disillusionment,” it remains a transformative technology with a current global market size estimated at $28 billion in 2024, projected to reach $60 billion by 2029 and growing at a compound annual growth rate (CAGR) of 16.8%. The delay in realising its full commercial potential can be attributed to the enormous capital expenditure required for infrastructure and the slow monetisation of these investments. However, its long-term impact is undeniable. 

5G enables IoT (Internet of Things), autonomous vehicles and smart cities. Its ultra-low latency and high bandwidth capabilities will revolutionise connectivity, driving massive innovation across industries.
