The Philips Hue ecosystem uses industry-standard encryption and authentication techniques to protect against unauthorized users gaining access to your Philips Hue products. Hue only connects to the internet securely via a dedicated cloud so your devices cannot be seen from the open internet. Hue products update regularly with the latest security fixes and patches — a feature you can activate by linking your Hue Bridge with a Hue account on www.philips-hue.com.
In addition to Hue’s security precautions, it is important for you to ensure your home network is secured as well. For more assistance on protecting your home network, contact your internet service provider.
