The Hidden Cost of Delaying Your Campus Network Refresh

There's a conversation I have regularly with IT leaders, it goes something like this: "Our campus switches and access points are old, but they're still running. We'll get to the refresh next budget cycle." Then next cycle arrives, and the same logic applies.

It's a reasonable position on the surface. Capital budgets are finite, and networking hardware doesn't generate the same sense of urgency as a new AI initiative, a cloud migration or an EHR upgrade. But after years of having this conversation, deferring a campus network refresh is rarely the cost-saving move it appears to be. The costs don't disappear; they just become harder to see.

This piece focuses on network infrastructure, the switches, access points and branch connectivity gear that everything else in your organization depends on. WWT's Luke Bernstein has written compellingly about the hidden costs of legacy application systems in healthcare, and the network layer deserves the same scrutiny. After all, no amount of application modernization delivers its full value on a network that can't keep up.

Here's what's actually happening on the balance sheet while the network refresh gets pushed.

Why delaying feels like the right call

Before we address the hidden costs, it's worth acknowledging why so many organizations end up here. IT teams are being asked to do more with less while managing an expanding list of strategic priorities. Cloud adoption, security tooling, AI infrastructure and workforce experience initiatives all compete for the same budget. Against that backdrop, hardware that's "still running" doesn't feel like an emergency.

And there's an element of truth to it. A five-year-old switch doesn't stop forwarding packets the day its manufacturer ends support. The problem is what you're no longer getting from your network and what you're quietly accumulating once that support window closes.

The four hidden costs

1. Security exposure that doesn't show up until it does

End-of-life network hardware stops receiving firmware updates and security patches. For healthcare and retail, that's a direct compliance liability.

Healthcare organizations running end-of-life campus infrastructure carry real HIPAA exposure. Patient data traverses that network constantly, from wireless clinical carts and bedside monitors to staff laptops and visitor Wi-Fi. When a vulnerability surfaces in an unpatched switch or access point, there's no fix coming. The only remediation is isolation, workaround or replacement, often under pressure and at a premium. HIPAA violations can trigger fines ranging from thousands to millions of dollars not to mention the reputational damage that follows a public breach disclosure adds to the cost.

Retail faces the same problem at the point of sale. PCI-DSS requirements are explicit about maintaining secure, supported infrastructure across cardholder data environments. An end-of-life access point isn't just a performance concern. It's an audit finding and a breach vector.

According to IBM, the average cost of a healthcare data breach now exceeds $10.93 million, the highest of any industry. The average campus network refresh is a fraction of that.

There's also a longer-horizon threat that's quietly becoming urgent: post-quantum cryptography. The encryption standards protecting data on your campus network today were designed for a pre-quantum world. Adversaries are already harvesting data now with the intent to decrypt it once quantum capability catches up. Legacy gear cannot support the modern cryptographic standards required to address this risk. Every year a refresh is deferred is another year of data in transit that may eventually be exposed.

2. The IT labor tax nobody budgets for

Modern campus platforms are built to reduce operational burden, automated provisioning, cloud-managed configuration, AI-assisted troubleshooting and proactive alerts. Aging infrastructure has none of that. Managing it is a manual, time-intensive process.

Think about what your team is doing every week to keep legacy gear running: manually applying configurations site by site, sourcing replacement parts for discontinued hardware, troubleshooting connectivity issues that a newer platform would flag and diagnose automatically. Those hours are real costs and they don't appear on a capital budget line. They appear in staff overtime, lower customer experiences, in slow ticket resolution and by experienced engineers spending their time on reactive maintenance instead of strategic work.

WWT's own analysis estimates that 60–80% of IT operational capacity, in many organizations, is consumed by maintaining legacy and end-of-life infrastructure. That's not a technology problem, it's a business problem. Every hour your team spends keeping old gear alive is an hour not spent on modernization, security hardening or the AI and automation initiatives on your roadmap.

For distributed organizations, a retail chain with hundreds of stores, or a health system with hundreds of clinics, this labor tax multiplies with every location.

3. User experience degradation is a business problem

Network performance isn't just an IT metric. It has a direct relationship to business outcomes, and aging campus infrastructure degrades it in ways that are easy to dismiss until you start attaching dollar values.

In retail, a slow or unreliable checkout experience caused by overloaded access points, aging switches or degraded application performance drives real consequences. Longer transaction times frustrate customers. Wireless checkout and mobile POS systems that depend on solid connectivity become liabilities instead of differentiators. Associate productivity suffers when the tools they rely on don't perform reliably.

In healthcare, the stakes are higher. Clinical workflows increasingly depend on wireless, from electronic health records accessed at the bedside to real-time communication between care teams. When the network is slow or connections drop, staff works around it. That workaround might be a clipboard. It might be a delay in medication administration. It might be a nurse walking across a unit to find a wired connection. None of that shows up in a network performance report, but all of it has a cost.

4. Operational rigidity that compounds over time

Perhaps the most underappreciated hidden cost is the ceiling that legacy infrastructure puts on what your organization can do next.

Wi-Fi 7 delivers the throughput and low latency that dense retail environments and high-acuity clinical settings increasingly require but it requires new hardware. AI-driven network operations that proactively detect issues before users notice them require platforms built to support those capabilities. IoT expansion, smart shelving in retail, connected medical devices in healthcare puts pressure on networks that were designed for a fraction of the device density now expected.

Every year you defer the refresh is another year you're operating below the capability floor your competitors are building on. The gap doesn't close on its own.

The tipping point: when waiting costs more than acting

Here's a simple framework for making this concrete. When evaluating whether to defer a campus refresh, add up the following for each additional year of delay:

• Security risk exposure: What is the potential cost of a breach or compliance finding given your current infrastructure posture?
• IT labor overhead: How many hours per month does your team spend maintaining legacy gear that modern platforms would automate?
• Productivity impact: What is the business cost of degraded network performance on your workforce and your customers?
• Capability gap: What initiatives are you unable to execute or executing at reduced effectiveness because your infrastructure can't support them?

In most cases, when organizations work through this exercise honestly, the cost of waiting equals or exceeds the cost of the refresh within one to two years, often sooner for large distributed environments.

The challenge is that these costs are challenging to quantify. They don't appear on a single invoice. That's what makes them easy to ignore and what makes them so effective as a business case when you pull them together.

Building the case internally

The next step is turning a network refresh ask into a conversation your finance and executive leadership can engage with. That means moving from "we need new hardware" to "here is the cost of not acting."

WWT helps organizations build that case. Our campus network assessment workshops are designed to give you an objective view of where your infrastructure stands today, what's at end-of-life, where your performance gaps are and what the realistic cost of delay looks like for your specific environment. 

Once you've made the internal case for action, the next question is how to approach lifecycle management systematically so you're never in this position again. 

In Elevate Your Branch & Campus Networking Lifecycle Management, co-authored with Samuel Clements, we cover the strategic framework executives need: from CISA's Binding Operational Directive on end-of-support edge devices, to post-quantum cryptography readiness, to building a phased modernization roadmap. Consider that article the architectural companion to the financial case made here.

The real question

The question isn't whether your campus network needs to be refreshed. In most organizations running hardware that's approaching or past end-of-support, the answer to that is already clear. The question is whether you're making a deliberate, informed decision about the timing or whether you're deferring because the cost of waiting is invisible.

It doesn't have to stay invisible.
