8 Trends Affecting Network Services

The eight network trends shaping business networks in 2026 are SD-WAN and SASE, multi-cloud networking, network digital twins, edge computing, network security, AI-driven automation, 5G and Wi-Fi 7, and IoT. Connected IoT devices alone reached 21.1 billion in 2025 (IoT Analytics, 2025), and each adds work for onsite IT network services at the edge.

New technologies and new approaches to existing ones arrive constantly. They make it easier to communicate and do business, but they also create real work for companies that are unprepared to adopt them, especially companies with many offices, branches or stores. This guide explains each trend in plain terms, what it changes at a branch office or network closet, and what it takes to run it well.

What are the biggest network trends in 2026?

Several network trends affect businesses this year, but eight stand out for medium to large organizations, and all of them are likely to continue for the foreseeable future. The table gives a quick view before we go deeper on each one.

1. Software-Defined Wide Area Network (SD-WAN) and SASE

A Software-Defined Wide Area Network (SD-WAN) is a virtual architecture that lets devices connect to applications regardless of the type of connection or location. It steers traffic across broadband, fiber, LTE or 5G links based on policy, which improves performance and reliability across the whole network.

SD-WAN appeared in the early 2000s, but it wasn’t until the mid-2010s that it became central to the networking problems larger organizations faced. Today most new deployments pair it with SASE (Secure Access Service Edge), which moves firewalling, secure web gateways and zero trust access into a cloud service so branch traffic is inspected without backhauling to headquarters.

For a multi-location company, SD-WAN is as much a field project as a software one. Every site needs a new appliance racked, circuits connected and labeled, a cutover window and someone onsite to confirm phones, printers and payment devices work afterward. Without skilled people at each site, rollouts slow down and misconfigurations can compromise the network’s performance and security. Our guide to firewall and SD-WAN rollouts with field IT support covers the site-by-site plan.

2. Multi-Cloud Networking

Multi-cloud networking (MCN) is the natural evolution of cloud networking. It is a service or software layer that lets companies use multiple public and private cloud resources while keeping visibility and control over the network connections between them. It is secure, easier to manage than a patchwork of separate connections, and scales well.

With MCN, companies can use the best cloud service for each job. For example, one provider may suit internal communications and data storage, while another is a better fit for customer-facing apps.

As companies move from a single cloud to MCN, they need multi-cloud policies plus consistent network and security policies across the entire organization, reviewed regularly. At the branch level, the shift means fewer local servers and more dependence on circuits, firewalls and Wi-Fi. When the cloud is where the work happens, a dead switch at a branch is a full outage for that office.

3. Digital Twin Networking Technology

A network digital twin is a computer-simulated model of a network, its operating environment and the traffic on it. IT teams use it to study network behavior, run simulations before changes and make recommendations that lead to a stronger network. The same concept is used well beyond networking:

• Manufacturing. Manufacturers use digital twin applications to model and optimize factories and production lines.
• Education. Schools and universities have used digital twins to plan campuses and support remote learning.
• Healthcare. Healthcare uses these applications to anticipate complications and for training.

Digital twins are excellent for being proactive, but they come with challenges. Real-time data and latency can make the model drift from reality, and data storage and security need the right expertise. There’s also a simpler problem: a twin is only as accurate as the inventory behind it. If nobody knows which switch is in which closet, or which port feeds which room, the model is wrong from day one. Physical audits, labeling and rack photos are often the first step.

4. Edge Computing

Many people use edge devices without realizing it. Smart watches, speakers and phones use edge computing to process data close to the user and send only what’s needed to the cloud.

Edge computing doesn’t require an additional network. It can live on devices, gateways or a small server in a network closet and connect existing architecture to the physical world. Examples in use today:

• Patient monitoring. Sensors on patients during an inpatient stay report on trends and behaviors in real time.
• Smart buildings. Thermostats, lighting and occupancy sensors respond instantly without a round trip to a remote server.
• Traffic management. Real-time monitoring lets traffic control centers react to patterns and fluctuations in demand.
• Retail and branches. Cameras, in-store analytics and point-of-sale systems process data locally so a slow circuit doesn’t stop the store.

The tradeoff is that edge computing puts more hardware in more places. Each small server or gateway needs to be installed, powered, cooled, patched and eventually replaced, usually in a closet with no IT staff nearby.

5. Network and Data Security

As technology becomes more sophisticated, so do breaches, and attackers are increasingly going after the network edge itself. In espionage-motivated breaches, exploitation of VPNs and edge devices accounted for 22% of cases, nearly eight times the prior year’s share, while organizations remediated only 53% of known exploited vulnerabilities in edge security devices (Verizon DBIR, 2025).

Data security should be a top priority for any organization, because one serious breach can damage a company’s future. Information governance helps companies comply with local, regional and global legislation and reduce cyber risk. To reduce risk, companies should:

• Develop a network crisis plan, including who goes onsite when a device must be isolated or replaced
• Monitor suspicious traffic and unusual activity
• Patch or replace firewalls, VPN concentrators and other edge devices on a schedule
• Develop BYOD policies and encourage best practices
• Educate employees on good cyber practices, especially phishing
• Move toward zero trust: segment networks and grant access by identity and device, not location

The stakes are high, both for breaches and for violating privacy laws. IT teams should routinely confirm that data is secure, and that includes the physical side: unused live ports, unlocked closets and forgotten devices are all ways in.

6. AI-Driven Network Automation

As networks grow, AI and machine learning have become part of how they’re run. AI-driven tools (often called AIOps) improve monitoring and reporting, helping IT teams spot issues, usage trends, anomalies and root causes faster. Over time these tools increasingly self-optimize and suggest fixes before a problem is felt by users.

What AI can’t do is walk into a closet. When the tool flags a failing power supply, a flapping port or an overheating switch, someone still has to reseat, replace or recable it. The best results come from pairing better remote insight with a fast way to get smart hands IT services to the site.

7. 5G and Wi-Fi 7

Wireless connectivity is essential to almost every business, and the standards keep moving.

• Public 5G. 5G has spread rapidly since its 2018 launch. For businesses, it is most useful as a fast backup or primary link for branches, pop-up sites and locations where wired circuits are slow to install.
• Private 5G. Organizations that depend on fast, secure data may choose a private 5G network, which restricts access to licensed or shared spectrum for better performance, security and lower latency. It’s used in places like warehouses, airports and manufacturing.
• Wi-Fi 6, 6E and 7. Wi-Fi 6 (802.11ax) improved speed and efficiency over Wi-Fi 5, Wi-Fi 6E added the 6 GHz band, and Wi-Fi 7 (802.11be) goes further with wider channels and multi-link operation. ABI Research forecasts 117.9 million Wi-Fi 7 access point shipments in 2026 (FutureFive, 2026).

The benefits only arrive if the infrastructure supports them. New access points may need more PoE power from the switch, better cabling and a fresh site survey. Our guide to Wi-Fi deployment with IT field support services walks through what that looks like across many sites.

8. Internet of Things (IoT)

With satellite offices, hybrid workspaces and remote teams, IoT has become a normal part of work. IoT Analytics counts 21.1 billion connected devices in 2025 and forecasts about 39 billion by 2030 (IoT Analytics, 2025).

In the workplace, that means cameras, badge readers, smart displays, sensors, printers and conference room systems on the network next to laptops and phones. Every device should meet requirements for firmware, configuration and segmentation, because more devices mean more opportunities for a breach. Our post on security cameras and access control field services covers the physical side.

Why do these network trends increase the need for onsite support?

IT professionals, whether on an internal team or at a managed service provider, are busy maintaining networks, building digital infrastructure and handling many other essential tasks. Many of the trends above make satellite offices, hybrid work and fieldwork easier. But they also put more equipment in more places, and that increases the need for onsite support.

A remote help desk can’t replace a skilled technician in the room for complex network work. Common onsite tasks created by these trends include:

Use on-site support to find and replace legacy hardware, remove security risks from out-of-date equipment, and fix the many issues that at best waste time and at worst cause a serious breach. A fractional, on-demand approach is a growing solution, because few companies can justify a full-time network technician at every location. For closet-level work specifically, see our guide to remote hands for network closets and IDFs.

How should multi-location companies prepare for these network trends?

1. Inventory every site. Know which switches, firewalls, access points and circuits are in each location, with photos and labels.
2. Find end-of-life gear. Prioritize edge devices and access points that no longer get security updates.
3. Standardize a site template. Pick a standard design for small, medium and large sites so rollouts are repeatable.
4. Plan cutovers by wave. Pilot at two or three sites, fix the runbook, then roll out in waves.
5. Line up field IT support. Decide who will be onsite at each location for installs, cutovers and break/fix, before the project starts.
6. Document as you go. Update diagrams and inventory after every visit so the next change (and any digital twin) starts from accurate data.

What mistakes do companies make when adopting new network technology?

• Treating SD-WAN or Wi-Fi upgrades as software-only projects and forgetting the site visits.
• Buying new access points without checking PoE budgets and cabling.
• Leaving old firewalls and VPN appliances in service after a SASE rollout.
• Adding IoT devices to the same flat network as laptops and servers.
• Relying on one person who “knows the closets” with no written documentation.

Frequently Asked Questions

What are the three most important network trends?

It depends on the industry, but for most companies the three most important network trends are SD-WAN (now usually paired with SASE), multi-cloud networking and edge computing. Together they change where traffic goes, where security is enforced and where data is processed, and all three put new equipment in branch offices that has to be installed and maintained.

How does the increase in remote work influence trends in network services?

Remote and hybrid work increase demand for reliable, fast connectivity from anywhere. They also require stronger security, which is driving the move from traditional VPNs to zero trust and SASE, and a heavier reliance on cloud services. Offices still matter, but they become collaboration hubs that need excellent Wi-Fi, AV and resilient circuits.

How are advancements in cybersecurity affecting the future of network services?

Cybersecurity advances bring better threat detection and data protection, and they push networks toward zero trust models where access depends on identity and device health rather than location. Attackers are targeting edge devices like firewalls and VPNs more often, so patching, replacing and physically securing that equipment is now a core part of network services.

How can emerging technologies like AI and machine learning influence network services?

AI and machine learning improve network efficiency, optimize traffic and predict faults or outages. They help automate configurations, spot anomalies and speed up root cause analysis. They don’t remove the need for physical work: when a tool flags failing hardware at a remote site, a technician still has to replace it.

What impact could network service trends have on my business operations?

Network trends can improve efficiency, strengthen security and enable better collaboration across locations. They also require investment in new hardware, training and onsite labor for installs and cutovers. Companies that plan site work early, standardize designs and document each location get the benefits faster and with fewer outages.
