Top confidential computing platforms include Microsoft Azure Confidential Computing, Google Cloud Confidential Computing, AWS Nitro Enclaves, Intel SGX/TDX-based solutions, AMD SEV-SNP-based solutions, IBM Cloud Confidential Computing, Fortanix, Anjuna, Edgeless Systems, and Scone, where Azure and Google lead in enterprise integration, compliance, scalability, and ease of use with strong VM-level TEEs, AWS excels in secure isolation within its ecosystem via Nitro Enclaves but is less multi-cloud friendly, Intel SGX offers the strongest fine-grained application isolation but is complex to develop, while AMD SEV-SNP and TDX provide better performance and simpler VM-level protection; meanwhile, Fortanix, Anjuna, and Edgeless Systems focus on multi-cloud portability and unified security management, making them ideal for privacy-focused and hybrid deployments in finance, healthcare, and regulated enterprise environments.
