Amazon is setting up a new shared network called Sidewalk that should improve the performance of internet-connected devices, but it also raises privacy concerns.

Sidewalk is being rolled out as privacy concerns mount over internet-enabled devices. Amazon says it’s taking precautions to protect users’ data, and that Sidewalk will do everything from simplifying device setup to extending the range of devices. But some experts say the fact that Sidewalk shares your network with strangers raises red flags.

“Amazon has taken steps to ensure the privacy of its customers’ data, but there are always unintended consequences and applications of new and untested technology,” Pieter VanIperen, managing partner at IT consulting firm PWV Consultants, said in an email interview. “The bigger issue here is that even though consumer data is protected from Amazon and its partners, bad actors will find a way to get it.”

Sidewalk works by linking together a variety of Amazon devices, including Ring Spotlight and Floodlight cameras and many Echo products. These gadgets will act as network bridges across the country.
