Why your employees' home Wi-Fi is your biggest business risk
Let's talk about home Wi-Fi and why it matters to business security. With so many employees working from home, it's become a real risk, but manageable with the right controls. Here's how to fix it ... Home Wi-Fi working hard, Connecting us to the office, Needs securing Every business relies on distributed teams, which means the office perimeter has stretched into living rooms, spare bedrooms, and kitchen tables, where home Wi-Fi quietly decides the fate of company data. This isn't scaremongering; it's a practical reality!When staff connect from a mix of routers, ISPs, and consumer devices, the organisation inherits network vulnerabilities it didn't create. That is why a clear plan for remote work security is no longer optional, especially when client commitments, compliance expectations and reputation depend on it. The first step is accepting that unmanaged employee networks can undo the best corporate controls. Weak passwords, out-of-date routers, and default admin settings are exactly what cybercriminals look for. If a handset or smart TV on the same network is compromised, lateral movement to a work laptop becomes plausible, and that is where data protection can fail. A strong, consistent standard for secure connectivity, enforced through policy and tooling, stops guesswork and reduces risk at scale.The next move is to separate traffic. Staff should use a dedicated SSID for work devices so employee networks don't mix personal gadgets with corporate endpoints. This simple change reduces attack paths, makes troubleshooting clearer and allows for cleaner monitoring. Pair that with enforced WPA3 where supported, or WPA2 as a fallback, and ensure routers have unique, strong admin credentials that are rotated and never shared informally. It's essential to control the device itself!Always-on VPN with split tunnelling disabled for sensitive roles ensures traffic termination is under business oversight, while DNS filtering blocks known malicious destinations before damage is done. Endpoint protection with EDR, disk encryption and strict patching timetables should be non-negotiable, because the best home router policy won't rescue an unpatched machine. These controls create a layered defence that treats the home like a branch office, not an exception. Visibility is the difference between hope and certainty. Lightweight agents can report OS versions, Wi-Fi security standards and compliance posture without invading privacy. When exceptions are flagged - old firmware, open guest networks, weak encryption - the business can act decisively. This proactive management aligns with remote work security objectives and demonstrates due diligence to clients and auditors who increasingly ask tough questions. Human behaviour matters!Clear, concise training that explains why changing default router passwords, updating firmware and avoiding cheap repeaters reduces cyber threats and gets better results than jargon-heavy manuals. Provide simple guides tailored to popular UK ISPs, offer support windows to help staff harden routers, and make it easy to request a pre-configured device if needed. Empowerment beats blame, and consistent reminders keep standards high. Procurement can help too. Offering a stipend for approved routers or shipping pre-hardened devices removes uncertainty. Standardising on models with reliable vendor updates and easy WPA3 configuration lowers long-term support costs. Where budgets allow, mesh systems with strong security and automatic updates are a sound investment, and they can be reclaimed or repurposed when staff leave.For those SMEs aiming to grow without compromise, the goal is straightforward: treat every home like an extension of the office, backed by policy, tooling and support. By closing gaps in employee networks, tightening configurations and maintaining oversight, organisations can reduce network vulnerabilities without blocking productivity. With a partner like Wolverton Solutions and a clear plan, home Wi-Fi becomes an asset, not a liability, and the business can scale remote operations with confidence. Until next time ...
