# AWS Cloud WAN example: Two segments and multiple AWS Regions
Example: Two segments, multiple Regions

This policy sets up two networks, `Secured` and `Non-Secured`, across three AWS Regions. Attachments with the tag `"Network" : "Secured"` map to `"Secured"`, while attachments with the tag `"Network" : "Non-Secured"` map to `"Non-Secured"`. All attachments require acceptance. Attachments can only talk within their segment but not across segments.
