KMS integrates with the AWS services and manages the creation, revocation, and automatic rotation of keys used to encrypt Customer Content.

6.3. Transit Encryption: Customer Content is transmitted securely via encrypted transport layer security (TLS) version 1.2 or higher leveraging modern ciphers over untrusted networks. Contentful uses AWS Certificate Manager (ACM) to centrally manage the lifecycle of TLS certificates, including their issuance, revocation, and automatic rotation.

6.4. Credential Management: Credential information, such as credentials used to facilitate communication between systems, used by Subscription Services are stored in AWS Secrets Manager. Access to these credentials is restricted to automated services and select individuals following the principle of least privilege.

7. Secure Disposal, Deletion & Storage of Customer Content

7.1. Storage: Customer Content is stored on AWS servers.

7.2. Deletion: Subscription Services include functionality that Customer may use at any time during the term of the Agreement to retrieve or delete Customer Content. Within 35 days of a written request by Customer upon termination or expiration of the Agreement, Contentful will delete (such that it cannot be recovered or reconstructed) all Customer Content within its possession or control.

7.3. Disposal: Customer Content is stored in AWS which ensures that media storage devices that reach the end of their useful life are decommissioned using techniques detailed in the National Institute of Standards and Technology (NIST) publication 800-88. Contentful personnel develop, access, and administer Subscription Services through Contentful Devices which are wiped prior to being reissued or decommissioned.
