The Philips Hue ecosystem uses industry-standard encryption and authentication techniques to help protect against unauthorized users gaining access to your Philips Hue products. Philips Hue only connects to the internet securely via a dedicated cloud, so your devices cannot be seen from the open internet. Philips Hue products update regularly with the latest security fixes and patches — a feature you can enable once you have a Bridge and a Philips Hue account.
You can also take steps to ensure your home network is secure. For more assistance on protecting your home network, contact your internet service provider.
