What is a modern network anyway?

Edge-to-cloud, built to transform your business. Learn more about it here.

As businesses grow, so do their networking needs – and legacy networks no longer cut it. 

These networks were typically built for the pre-cloud, pre-digital era, which means they’re often slowed down by outdated hardware, limited bandwidth, and legacy systems that have been patched together. This leaves organizations struggling to support today’s fast-paced, connected environments. And it ultimately means they fall behind their competitors. 

Not only are these legacy networks often slow, unreliable, expensive to maintain and vulnerable to cyber threats, but they also lack the intelligence and automation needed for today’s modern demands, like remote work and real-time data processing.

Compared to a modern network like HPE Aruba Networking, which utilizes tools such as AI, centralized management, and zero-trust security, legacy networks are slow to adapt, costly to maintain, and vulnerable to cyber threats. In short, a legacy network holds businesses back, while a modern network drives them forward with agility, efficiency, and built-in readiness for the future.

But what does a modern network actually look like? Let us explain.

So, what is a modern network?

A modern enterprise network is more than just a network. It’s a smart system that connects all the devices, systems and applications in a business so they can talk to each other quickly and securely, safely and quickly. 

Think of it like the digital nervous system of a modern business, built with smart technology that can fix problems, protect against hackers, and keep everything running smoothly without needing lots of hands-on work. Unlike traditional networks, which are typically slow and hard to manage, a modern network is fast, flexible, and designed for how we work today – with cloud apps, remote teams, and lots of connected IoT devices.

Modern network providers like HPE Aruba Networking provide organizations with a wide range of technologies to support the demands of today’s digital businesses.  

With HPE Aruba Networking’s cloud-native architecture and AI-powered automation, businesses can simplify network operations, reduce manual tasks, and gain real-time visibility and control over their entire infrastructure.

HPE’s Aruba Networking Central, for example, equips organizations with a unified platform that allows time-poor IT teams to manage everything from a single dashboard, whether users are in the office, working remotely, or on the move. This simplifies troubleshooting, speeds up deployment, and improves overall performance. 

This wide-ranging visibility is a feature often missing from ageing networks that continue to rely on siloed hardware, manual configurations, and outdated management tools that leave IT teams struggling to see what’s happening across the entire network.

CASE STUDY 1: Steel manufacturer

One of the UK’s largest independent steel stockholders decided it was time to ditch its legacy router technology in favour of all-broadband SD-WAN; it was tired of the outages and unreliability of its legacy network, which ultimately resulted in a negative customer experience. 

The company chose HPE Aruba Networking’s EdgeConnect SD-WAN edge platform, which stood out for its technical edge over competitors, and the decision is already paying off: not only has the company seen a 25% reduction in costs, HPE Aruba Networking EdgeConnect has also provided the firm with much-needed reliability for its critical VoIP systems, an increase in productivity, and has accelerates the time it takes to bring up newly acquired sites from months to hours.

Scalability, security, flexibility

Scalability is another major benefit of ditching legacy tech for a modern network. That’s because legacy technology struggles to handle modern demands like cloud computing, IoT, and hybrid working – and it’s obvious when you realize these require flexible, dynamic resource allocation. In stark contrast, modern networks are built with scalability at the forefront. 

By making use of features such as using cloud-based management and AI-driven automation, modern networks allow organizations to quickly add new devices, users, and locations without complex manual configurations, while support for evolving technologies ensures the network can grow alongside business needs. 

This flexibility means organizations can scale efficiently, maintain performance, and adapt rapidly to changing demands without costly infrastructure overhauls.

Modern networks also help organizations to defend themselves against modern security threats. Businesses still relying on outdated infrastructure are an easy target for hackers; they rely on static, perimeter-based defenses that can’t protect against sophisticated threats, poor segmentation allows attackers to move freely once inside, and manual configurations increase the chance of human error. 

HPE Aruba Networking, on the other hand, offers modern security features that have been designed with modern, distributed networks in mind. At its core is zero-trust security, which verifies every user and device before they’re granted access to the network and ensures users only reach what they’re authorized to. 

By integrating advanced technologies such as artificial intelligence and machine learning, modern networks are also equipped to detect and respond to threats in real time. HPE Aruba Networking ClearPass, for example, provides advanced network access control, a wide range of encryption methods, and seamless integration with third-party security tools to further strengthen protection. 

Zero trust networks: essential in the age of AI

AI is being used to improve efficiency, including cybercriminals. Attackers are now using AI to launch more sophisticated threats that can bypass traditional defences. Protecting the organisation in the age of AI requires zero trust security at the network level while securing critical digital entry points.

This eBook explores AI-enabled attacks, zero trust defence and how HPE AI-powered networking strengthens security across the network.

Case study 2: Global steel leader

A global steel leader recognized the importance of modernization and recently set out on a mission to rid itself of legacy technology in favour of a network that would allow it to support sustainability goals, speed up onboarding, reduce operational costs and streamline the secure adoption of IoT and AI-enabled technologies

The company deployed HPE Aruba Networking’s EdgeConnect SD-Branch across 70 sites, and the benefits were immediate: the group reduced connectivity costs by approximately 40% and accelerated the rollout of new locations. The unified infrastructure–which incorporates modern technologies such as Wi-Fi 6 and zero-trust security–also enhanced application performance and user experience, while HPE Aruba Networking Central’s AI-driven insights enabled the company to streamline operations and improve visibility across its global network. 

Time to modernize

To stay competitive and secure in today’s increasingly digital world, businesses need to move on from legacy networks.

Businesses that fail to modernize their networks risk falling behind in several key areas. Without a fast, reliable, and secure network, they may experience reduced productivity, poor customer experiences, and prove to be a key target for cybercriminals. 

Modern networks like HPE Aruba Networking offer advanced features such as AI-powered automation, enhanced security, and seamless connectivity across devices and locations. These capabilities support cloud integration, remote work, and IoT expansion – critical for modern operations.

Failing to adopt these modern capabilities can lead to operational inefficiencies and lost opportunities in a fast-paced digital economy.
