SpatialKey uses state-of-the-art security. SpatialKey On-Demand is a Software as a Service (SaaS) application built on top of the Amazon Web Services (AWS) platform. We use both the Amazon Elastic Computing Cloud (EC2) and Simple Storage Service (S3) as part of our infrastructure. An overview of the security processes taken for AWS can be found here. Additionally, all communication between the client and server is encrypted with HTTPS using SSL to prevent eavesdropping on data as it passes from the Amazon cloud to your client.
