Smart Devices at Home Are a Risk to Your Work Data

You finished a client call at 9am, closed your laptop, and walked past the smart TV in the lounge on the way to make a coffee. Everything felt normal. But if your home has smart devices sharing the same Wi-Fi as your work laptop, there is a real gap in your security that most people never think about.

Smart home devices - streaming sticks, voice assistants, smart speakers, even modern appliances - connect to the internet but were never built with security in mind. They rarely receive updates, they often still run with the default username and password that came in the box, and they have no built-in protection against attack. A hacker who wants access to your work laptop does not need to attack it directly. They can breach a poorly secured smart device on the same network and use it as a stepping stone. Once they are in, they can see every other device connected to that Wi-Fi.

This matters more now that working from home is routine. Your work laptop, client files, and business email are sitting on the same network as devices that were designed for convenience, not security. The NZ Privacy Act 2020 puts obligations on businesses to protect personal information, and a breach that starts from a compromised home device is still a breach. For anyone in a profession that handles sensitive client data - health, legal, financial - that is a serious exposure. It is also worth understanding the less obvious ways hackers get into business accounts to see how quickly these risks compound.

The fix is straightforward. Most modern home routers let you create a second Wi-Fi network, often called a guest network. The idea is simple: put all your smart home devices on that separate network, and keep your work and personal computers on the main one. When the two networks are separate, a hacker who compromises your smart TV cannot see your laptop at all. The bridge between the two disappears. If you want to go a step further, use a name for your networks that gives nothing away - not your address, your name, or anything that tells someone what kind of network they are looking at.

If you work from home even part of the time, it is worth getting this sorted properly rather than guessing at router settings. A quick check of your home setup - separating networks, reviewing connected devices, and making sure passwords are not still set to factory defaults - takes an hour and removes a genuine risk.
