In short
Smart-home devices should get updates, have their own passwords and ideally run on a separate network. When buying, the manufacturer's update commitment is a key criterion.
What is it?
Connected household devices talk to the manufacturer's apps and cloud services. Weak passwords or missing updates make them vulnerable.
Who is it useful for?
Anyone with connected cameras, voice assistants, door locks or appliances.
What does it protect against?
- Outside access to cameras and devices (through own passwords and MFA)
- Spread to your computers (through separate networks)
What does it not protect against?
- Data processing by the manufacturer itself
- Devices that no longer receive updates
What you can do for free
- 01Move devices to the guest network or a separate network
- 02Change default passwords, use MFA for the vendor account
- 03Turn on automatic updates
- 04Turn off unused remote access
When is an extra product worth it?
When buying new, a device with a clear, long update commitment is worth it – even if it costs a little more.
