AWS is aware of a recent Cyber Safety Review Board (CSRB) report regarding a 2023 Microsoft Online Exchange issue. We are not affected by the issues described in this report and no customer action is required.
At AWS, security is our top priority. Every AWS customer benefits from the fact that we have the most operational experience of any cloud provider. We designed AWS from its very foundation to be the most secure way for our customers to run their workloads, and built our internal culture around security as a business imperative. The security of the AWS cloud is unique and differentiated by our technology, culture, and practices.
