Understanding the Risks of Remote Work: Securing Your Home Office

Hello, Mauven here.

Remote work did not sneak up on us. The shift had been building for years before 2020 forced the issue. But for millions of small businesses across the UK, the transition from a managed office environment to a collection of kitchen tables and spare bedrooms happened almost overnight, with very little time to think about what that actually meant for security.

Four years on, many of those arrangements have become permanent. And yet the security thinking has not always caught up with the reality.

The Problem Is Not the Technology

When I talk to small business owners about remote work risks, the conversation usually starts with kit: routers, VPNs (virtual private networks, which create a secure, encrypted tunnel between a device and your business systems), endpoint protection. All of that matters. But it is not where most incidents begin.

Most incidents begin with a behaviour. An employee clicking a link on a personal device. A password shared over a WhatsApp message. A video call taken in a coffee shop with a sensitive document visible on screen. The technology was fine. The human context was not.

This is the gap that policy and behavioural thinking exists to close.

What Makes the Home Office Different

The office environment, even a modest one, carries a kind of passive security infrastructure. Colleagues can see each other. There is a shared sense of what is and is not appropriate. Someone printing a sensitive document and leaving it on the printer gets noticed. Social norms enforce certain behaviours without anyone having to say a word.

The home office strips all of that away. Your employee is alone, comfortable, and surrounded by personal habits and personal devices. The boundaries between work and home life blur. That blurring is not a moral failing; it is a predictable human response to environment.

Under the UK GDPR (General Data Protection Regulation), your organisation is still responsible for how personal data is handled, regardless of where your staff are working. The law does not care that someone was using their own laptop at home. If data is lost or mishandled, the accountability sits with the business.

The Risks Worth Taking Seriously

Unsecured Home Wi-Fi Networks

Most home routers come with default passwords that many people never change. A neighbour, a visitor, or someone parked outside with a laptop could potentially access an unsecured network. Once on the same network as your employee’s work device, the risks increase significantly.

This is not a hypothetical. The National Cyber Security Centre (NCSC) consistently flags home network security as a priority concern for remote workers. The good news is that fixing it is straightforward and costs nothing except a few minutes of someone’s time.

Personal Devices Used for Work

This is sometimes called BYOD, which stands for Bring Your Own Device. It is enormously common in small businesses because it feels practical and cost-effective. Why buy a laptop when the employee already has one?

The problem is that personal devices do not follow your business rules. They may not have up-to-date software. They almost certainly have personal apps, personal accounts, and personal browsing history running alongside work activity. When someone’s personal email account is phished, the attacker may find themselves one click away from your business data too.

Cyber Essentials, the UK government-backed certification scheme, specifically addresses device controls. If you have staff using personal devices for work, you need a clear policy, and that policy needs to be understood and followed, not just filed somewhere.

The Visibility Problem

In an office, a manager can see if something seems off. At home, that visibility is gone. Insider risk, which means the risk posed by employees whether through malice or simply through carelessness, is harder to detect in a distributed environment.

More commonly, it is not malice at all. It is someone who does not realise they are doing something risky. Forwarding a work email to a personal account to finish something over the weekend. Saving a file to a personal cloud storage service because it is easier. These are convenience-driven behaviours, not malicious ones, but they carry real consequences.

Phishing in a Home Context

Phishing, which means fraudulent emails or messages designed to trick people into revealing information or clicking harmful links, is the most common route into a business. Remote workers are particularly vulnerable because they lack the informal checks that office life provides.

In an office, someone might say: “Did you get a weird email from IT? I’m not sure if it’s real.” At home, that conversation does not happen. The employee has to make the judgement call alone, often quickly, often while distracted.

Human decision-making under pressure and isolation is simply less reliable than human decision-making in a supported, social environment. This is not a criticism of your staff. It is cognitive science.

What Good Policy Actually Looks Like

Policy in the context of remote work is not a document on a shared drive that nobody reads. Effective policy is a set of shared expectations that are communicated clearly, reinforced regularly, and actually reflected in how the business operates.

Here is what that looks like in practice for a small business.

Clear rules about which devices can access which systems. If you use a cloud-based accounting package or a CRM (customer relationship management) system, who is allowed to access it, and from what kind of device? Write it down. Tell people. Check that they understand it.

A minimum standard for home network security. This does not need to be technical. It can be as simple as: “Please change your router’s default password, and make sure your Wi-Fi uses WPA2 or WPA3 encryption.” Your IT support provider or a Cyber Essentials assessor can help you put this into plain language.

A process for reporting anything suspicious. People do not report near-misses or suspicious emails if they think they will be blamed for clicking the wrong thing. Create a culture where reporting is encouraged, not penalised. The behavioural research on this is consistent: blame cultures suppress reporting, and suppressed reporting allows small problems to become large ones.

Regular, short reminders rather than annual training. Annual security awareness training is better than nothing, but it is not enough on its own. A short message or brief discussion every few weeks keeps security visible without becoming burdensome. The NCSC’s Small Business Guide offers free, accessible resources that work well in this format.

The Incentive Problem

Here is something worth sitting with. Your employees are not primarily motivated by your security policy. They are motivated by doing their job well, finishing on time, and keeping things simple. Security often feels like friction: extra steps, extra rules, extra things to remember.

If your security measures make people’s lives significantly harder, they will find workarounds. Not because they are careless or disloyal, but because that is what people do when systems create unnecessary friction. The workarounds are usually less secure than the original system.

This means that the best remote work security is security that fits naturally into how people already work. A password manager (a tool that stores and fills in passwords securely) removes the friction of remembering complex passwords. Single sign-on (a system that lets staff access multiple tools with one set of credentials) reduces the number of logins people need to manage. Multi-factor authentication (an extra verification step beyond a password, such as a code sent to your phone) can be set up so that it is quick and habitual.

Design for the behaviour you want to see, not the behaviour you wish people would have.

A Note on Shared Spaces

Not everyone works from a private home office. Some employees work from kitchen tables with family members present. Some work from co-working spaces or cafes. Some switch between multiple locations in a single day.

Each of these contexts carries different risks. A family member glancing at a screen is a low-level information risk but still a real one, particularly if you handle sensitive client data. A co-working space is effectively a shared network with strangers.

Under the UK GDPR, accidental disclosure of personal data, even to a family member, can constitute a data breach depending on the circumstances. This is not about scaring anyone. It is about making sure your staff understand that “working from home” does not automatically mean “working privately.”

A simple screen privacy filter (a physical attachment that narrows the viewing angle of a laptop screen) is a low-cost, practical solution for anyone who regularly works in shared spaces.

Regulatory Context

The NCSC’s Cyber Essentials scheme covers five technical controls: firewalls, secure configuration, user access control, malware protection, and patch management (keeping software up to date). All five are directly relevant to remote work environments.

Cyber Essentials certification is not mandatory for most small businesses, but it is increasingly expected by clients in certain sectors, particularly if you work with the public sector or handle sensitive contracts. More importantly, the discipline of working through the controls gives you a structured way to identify gaps in your remote work setup.

The Information Commissioner’s Office (ICO) also publishes guidance specifically on home working and data protection. It is readable, practical, and free. If you are not sure whether your current arrangements meet your UK GDPR obligations, that guidance is a good place to start.

What You Should Do Now

These are concrete, prioritised actions you can take in the next two weeks without needing specialist technical knowledge.

1. Ask your staff one simple question. “Are you using any personal devices or personal accounts to do work tasks?” The answers will tell you more than any audit. Do this without blame; you are trying to understand reality, not catch people out.

2. Set a minimum standard for home Wi-Fi. Send a brief, friendly message to anyone working remotely. Ask them to check that their router password has been changed from the default and that their Wi-Fi uses WPA2 or WPA3 encryption. Most modern routers show this in their settings. If they are not sure how, offer to arrange ten minutes of support.

3. Turn on multi-factor authentication for your core tools. Start with email, then cloud storage, then any finance or HR systems. Most services offer this for free. The NCSC’s guidance on multi-factor authentication explains how to set it up in plain language.

4. Create a one-page remote work policy. It does not need to be long. Cover: which devices can be used for work, what staff should do if they receive a suspicious message, and how to report a potential security incident. Make it human and clear, not legalistic.

5. Read the ICO’s home working guidance. Spend thirty minutes with it. Identify one thing your business is currently not doing that you should be. Then fix that one thing before moving on to the next.

Remote work is not going away. The risks it introduces are manageable, but only if you treat them as the people problems they actually are, and build your response around how people genuinely behave, not how you wish they would.
