Frequently asked questions

What matters most for smart home iot security: router, updates & network segmentation?

Treat every connected device as part of the network’s security surface. Maintain an inventory, install supported updates, replace default credentials and use router or network segmentation features where appropriate.

How should I test this?

List devices and support status. Change default passwords. Enable authenticated updates. Review router and guest/IoT network controls.

Does a faster internet plan fix Wi-Fi?

Not when the bottleneck is signal, interference, device compatibility or the local network.
