Smart TVs, doorbells, thermostats, fridges—even our toasters are getting “smarter.” As connected devices continue to flood homes, workplaces, and even public spaces, we’re gaining convenience—but at the cost of serious privacy risks. What many users don’t realize is that every smart device is essentially a data collector. And unless you take steps to protect your data, you’re putting your personal information at risk.
In this blog, we’re breaking down what these devices collect, why it matters now more than ever, and—most importantly—seven practical ways to protect your data before it’s compromised.

1. Understand What Smart Devices Collect
Smart devices are always on. They gather far more than you might expect—from your location and voice patterns to your habits, preferences, and even health data.
Take smart speakers, for example. They’re not just waiting for the wake word. Many record snippets of audio, which are stored in cloud servers and sometimes reviewed by humans to improve voice recognition. Fitness wearables track not only steps but sleep patterns, heart rates, and location.
What’s more concerning? Much of this data is stored, shared, or sold. Understanding what your devices collect is the first step in safeguarding your privacy.
2. Protect Your Home Network First
If your home Wi-Fi isn’t secure, then every connected device on that network becomes vulnerable. And unfortunately, most people still rely on default router settings or simple passwords like “admin123” (please, change that now).
Here’s how to secure your home network:
- Use a strong, unique Wi-Fi password.
- Rename the default SSID (network name) to something generic.
- Turn on WPA3 encryption if your router supports it.
- Create a guest network for your smart devices so they’re isolated from your personal data and main devices.
Remember: your network is the digital front door to your life. Don’t leave it wide open.
3. Use Multi-Factor Authentication (MFA)
Your smart device accounts often serve as access points for attackers. That’s why MFA is no longer optional—it’s essential.
Multi-factor authentication requires more than just a password. It might be a fingerprint, facial scan, or a time-sensitive code sent to your phone. Major tech companies like Google, Apple, and Microsoft all offer MFA across their platforms—and enabling it takes just a few clicks.
It’s one of the simplest ways to protect your data, even if your password is leaked in a breach.
4. Update Firmware and Software Regularly
Cybercriminals love outdated firmware. Many device hacks happen because users don’t apply security updates provided by manufacturers.
Manufacturers release firmware and app updates to fix vulnerabilities and bugs—sometimes even weeks after discovering a new threat. That’s why your smart thermostat, camera, speaker, or router should always be running the latest version of its software.
Enable automatic updates where available, or set a monthly reminder to check for them manually.
5. Control App Permissions Wisely
Every time you install a companion app for a smart device, it likely requests permissions—some of which may have nothing to do with its functionality.
Ask yourself:
- Why does a flashlight app need access to my contacts?
- Does my smart fridge app need my location?
On both Android and iOS, you can manage app permissions in your phone settings. Revoke access to the microphone, camera, contacts, and other sensitive data if it’s not absolutely necessary. This step alone can significantly reduce how much personal information you’re leaking every day.
6. Protect Your Data with Encryption
If you’re not encrypting your data, you’re giving attackers an open invitation. Luckily, encryption tools are easier to use than ever.
Start with a VPN (Virtual Private Network). VPNs like NordVPN, ExpressVPN, or ProtonVPN encrypt your data in transit, making it unreadable to hackers—even on public Wi-Fi.
Many newer smart devices also offer end-to-end encryption by default, especially in categories like security cameras and messaging devices. Look for this feature when buying new devices—and activate it during setup.
Encryption scrambles your information, making it useless to anyone who intercepts it.
7. Stay Informed with Trusted Newsletters
