# Hardware with SGX Support ### CPU SGX was first introduced in 2015 with the sixth generation Intel Core microprocessors based on the Skylake microarchitecture. Lists with SGX feature enabled CPUs are maintained by Intel at:\ [SGX with Intel® ME](https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=873&2_SoftwareGuardExtensions=Yes%20with%20Intel%C2%AE%20ME)\ [SGX with Intel® SPS and Intel® ME](https://ark.intel.com/content/www/us/en/ark/search/featurefilter.html?productType=873&2_SoftwareGuardExtensions=Yes%20with%20both%20Intel%C2%AE%20SPS%20and%20Intel%C2%AE%20ME) Some of the initial 2015 released CPUs do not support SGX. Only specific S-Spec support it.

Please consult the hardware manufacturer.\ SGX must be set to ENABLED in the system BIOS. ### Cloud Service Providers | Vendor | Servicename | CPU SGX capable | SGX activated in BIOS | Date | Source | | ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------- | --------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------ | | Azure | [Azure Confidential Computing Public Preview](https://azuremarketplace.microsoft.com/en-us/marketplace/apps/microsoft-azure-compute.confidentialcompute?tab=Overview) | YES, SGX1 | YES, SGX1 | Oct 2018 | [Blog](https://azure.microsoft.com/en-us/blog/protect-data-in-use-with-the-public-preview-of-azure-confidential-computing/) | | IBM | [IBM Cloud Bare Metal Instances](https://www.ibm.com/blogs/bluemix/2018/05/data-use-protection-ibm-cloud-using-intel-sgx/) | YES, unknown version | YES | May 2018 | [Issue 46](https://github.com/ayeks/SGX-hardware/issues/46) | | packet.net | [Reserved Hardware](https://www.packet.com/cloud/all-features/) | YES, SGX1 | YES | Apr 2018 | [Issue 44](https://github.com/ayeks/SGX-hardware/issues/44) | | Alibaba Cloud | [ECS Bare Metal Instance](https://www.alibabacloud.com/product/ebm) | YES, unknown version | YES | Sep 2018 | [Docs](https://www.alibabacloud.com/help/doc-detail/60576.html), [Issue 50](https://github.com/ayeks/SGX-hardware/issues/50) | | OVHcloud | [Infrastructure Dedicated Servers](https://www.ovh.com/ca/en/dedicated-servers/infra/) | YES, unknown version | YES | Sep 2019 | [Docs](https://www.ovh.ie/dedicated_servers/software-guard-extensions/), [Issue 66](https://github.com/ayeks/SGX-hardware/issues/66) | --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
