Amazon GameLift now supports publishing events to encrypted Amazon SNS topics

Amazon GameLift can now publish events to Amazon Simple Notification Service (Amazon SNS) topics that have server-side encryption (SSE) enabled, for additional protection of events that carry sensitive data. Amazon GameLift is a fully managed solution that allows you to manage and scale dedicated game servers for session-based multiplayer games. With this release, customers can now enable server-side encryption to receive player matchmaking and game session queue notifications from the GameLift service.
