Connections between AWS IoT SiteWise and on-premises applications, such as SiteWise Edge gateways, are secured over Transport Layer Security (TLS) connections. For more information, see Encryption in transit.

AWS IoT SiteWise doesn't support connections between Availability Zones within an AWS Region or connections between AWS accounts.

You can configure IAM Identity Center in only one Region at a time. SiteWise Monitor connects to the Region that you configured for IAM Identity Center. This means that you use one Region for IAM Identity Center access, but you can create portals in any Region.
