Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Amazon IoT Greengrass Version 1 no longer receives feature updates, and will receive only security patches and bug fixes until June 30, 2023. For more information, see the Amazon IoT Greengrass V1 maintenance policy. We strongly recommend that you migrate to Amazon IoT Greengrass Version 2, which adds significant new features and support for additional platforms.

Data encryption

Amazon IoT Greengrass uses encryption to protect data while in-transit (over the internet or local network) and at rest (stored in the Amazon Web Services Cloud).

Devices in a Amazon IoT Greengrass environment often collect data that's sent to Amazon services for further processing. For more information about data encryption on other Amazon services, see the security documentation for that service.
