Work From Home Security: Is Your Home Office Setup Secure?

The home office has become permanent for millions of South Africans. What started as an emergency arrangement has settled into the new normal — and nearly 47% of South African employees now have the ability to work remotely at least part of the time. 

The problem is that most home setups were never designed with work security in mind. The same connection you use to stream movies and let the kids game is now carrying client data, company emails, financial documents, and proprietary files. And almost nobody set it up with that in mind. 

The Gaps Most Work-From-Home Setups Have 

Shared devices. In a household where everyone uses the same laptop, your work files and personal browsing share the same environment. If someone in the family downloads something malicious, it reaches your work data too. Research shows remote workers are three times more likely to accidentally expose data than office-based employees — and shared devices are a significant contributor. 

Unsecured Wi-Fi. The home router most people use is whatever the ISP installed. It likely hasn’t had its firmware updated in years. The admin password is probably still the factory default. And every device in the house — from smart TVs to the kids’ tablets to whatever IoT devices you’ve added over the years — shares that same network. When you connect your work laptop to it, you’re joining a network that nobody has hardened. 

No VPN. In an office, traffic between your device and company systems travels over a managed, encrypted internal network. At home, it travels over your general internet connection. A VPN creates an encrypted tunnel that prevents your internet service provider and anyone else from seeing what you’re sending and receiving — something companies routinely provide to remote staff, but that many home workers have never set up. 

Saved passwords and unencrypted storage. The browser-saved passwords on a shared family laptop are a single point of failure. If one family member’s browsing leads to credential theft, everything saved in that browser — including your work accounts — is potentially exposed. 

What a Properly Secured Home Office Actually Looks Like 

This doesn’t require enterprise infrastructure. It requires a few deliberate choices: 

A dedicated work device. If you work from home regularly, your work device should be yours alone — not shared with family. This is the single most impactful change you can make. It keeps your work environment clean, separate, and manageable. 

Endpoint protection. ESET endpoint security running on your work device provides real-time protection against malware, phishing links, and suspicious downloads. It runs quietly in the background and doesn’t interfere with productivity. For remote workers, it’s the equivalent of the security software your IT department would have installed on an office machine. 

A separate work network or VPN. Even a simple guest network dedicated to work devices — separate from the family network — dramatically reduces the exposure of your work laptop to whatever else is happening on your home network. Combined with a VPN for accessing company systems, this is a meaningful security improvement that costs very little. 

Properly configured Microsoft 365. If your employer uses Microsoft 365, Multi-Factor Authentication should be enabled on your account. This means a stolen password alone is not enough to access your work email, files, and systems. It takes about ten minutes to set up and is one of the highest-return security measures available to any remote worker. 

The Employee’s Perspective vs the Employer’s 

Many remote workers assume their employer’s IT team is responsible for securing their home setup. Many employers assume their staff have done the basics. In reality, 48% of organisations suffered data breaches from personal devices in 2024 despite most companies allowing remote access from those same devices. 

The gap falls between the two assumptions. Nobody explicitly owns it. And when something goes wrong, it’s the employee’s data, the company’s breach, and everyone’s problem. 

Taking responsibility for your own home office security isn’t just professional — it’s practical. You’re the one who knows exactly what’s on your laptop, what your home network looks like, and what the weak points are. A small amount of attention now prevents a significant problem later. 

The 30-Minute Security Audit 

You don’t need a full IT review to meaningfully improve your home office security. You need to check four things: 

Is your work device dedicated to work, or shared? Is endpoint protection installed and running? Is your router’s admin password still the factory default? Is MFA enabled on your work email and key applications? 

If the answer to any of those is “no” or “I’m not sure,” that’s where to start.
