Tamperproof, unstructured data store hosted in trusted execution environments (TEEs) and backed by cryptographically verifiable evidence. Azure confidential ledger provides a managed and decentralized ledger for data entries backed by blockchain. Protect your data at rest, in transit, and in use with hardware-backed secure enclaves used in Azure confidential computing. Ensure that your sensitive data records remain intact over time. The decentralized blockchain structure uses consensus-based replicas and cryptographically signed blocks to make information committed to Confidential Ledger tamperproof in perpetuity. You’ll soon have the option to add multiple parties to collaborate on decentralized ledger activities with the consortium concept, a key feature in blockchain solutions. Trust that your stored data is immutable by verifying it yourself. Tamper evidence can be demonstrated for server nodes, the blocks stored on the ledger, and all user transactions.

AWS Nitro Enclaves enables customers to create isolated compute environments to further protect and securely process highly sensitive data such as personally identifiable information (PII), healthcare, financial, and intellectual property data within their Amazon EC2 instances. Nitro Enclaves uses the same Nitro Hypervisor technology that provides CPU and memory isolation for EC2 instances. Nitro Enclaves helps customers reduce the attack surface area for their most sensitive data processing applications. Enclaves offer an isolated, hardened, and highly constrained environment to host security-critical applications. Nitro Enclaves includes cryptographic attestation for your software, so that you can be sure that only authorized code is running, as well as integration with the AWS Key Management Service so that only your enclaves can access sensitive material.
