Short answer: smart TVs are generally safe, but like any connected device they can collect viewing data, show targeted adverts and become vulnerable if they stop getting updates. Keep software updated, review privacy settings, secure your Wi-Fi and only install apps from the official store.
The main smart TV security risks
- Viewing data (ACR): many TVs can recognise what is on screen to personalise adverts.
- Outdated software: TVs that no longer receive updates may have unpatched security flaws.
- Unofficial apps: sideloaded apps and pirate IPTV services can contain malware.
- Weak Wi-Fi security: an unsecured network exposes every device on it.
- Microphones and cameras: voice assistants listen for wake words; some TVs have cameras.
How to protect your smart TV
- Turn on automatic software updates.
- Switch off ACR / viewing information in privacy settings (named differently by brand).
- Limit ad personalisation and disable voice assistants you do not use.
- Use WPA2 or WPA3 Wi-Fi with a strong password.
- Only install apps from the official app store.
- Avoid “free” services offering paid channels — they are unlicensed and risky.
- Reset the TV to factory settings before selling it.
Where to find privacy settings
| Brand | Where to look |
|---|---|
| Samsung | Settings → General & Privacy → Terms & Privacy |
| LG | Settings → General → System → Additional Settings / User Agreements |
| Sony / Google TV | Settings → Privacy |
| Hisense / TCL | Settings → Privacy or System |
Menu names change between model years, so search your TV’s manual if you cannot find them.

Voice assistants listen for a wake word or button press. You can disable the microphone or assistant in settings.
Do I need a VPN on a smart TV?
Not for normal use. Securing your router and keeping the TV updated matters more.
