Reports requiring an NDA are accessible by signing the terms and conditions in AWS Artifact. You must accept the AWS Artifact NDA to access and download confidential documents in AWS Artifact. You must sign the NDA each time that you access confidential reports.
If you have an existing NDA with Amazon covering the same confidential information as provided in AWS Artifact, then your existing NDA applies. You can use your existing NDA instead of the AWS Artifact NDA.
