+# Cloud Providers
+
+If you are aware of more cloud or dedicated server providers that activey support Intel SGX or Intel TDX, or have updated information about the providers listed on this page, please [create an issue on Github](https://github.com/oasisprotocol/docs/issues/new) with the additional details.
+
+Before committing to a service be sure to verify the processor compatibility and enquire with the provider about the status of Intel SGX support. Intel maintains a comprehensive list of processors that support Intel SGX:

+
+
+## Possible Limitations
+
+While many bare-metal or dedicated server providers use Intel processors that support SGX, there are potential limitations:
+
+ 1. **BIOS Configuration:** Some providers may not allow customers to access or modify BIOS settings, which is necessary to enable SGX.
+ 2. **Outdated Firmware:** SGX requires up-to-date firmware. Some providers may not maintain their systems with the latest firmware updates, preventing SGX from functioning correctly.
+ 3. **Lack of SGX-specific Offerings:** Many providers may not advertise or specifically offer SGX-enabled servers, making it difficult for customers to know if the feature is available.
+ 4. **Limited Support:** Even if SGX is available, the provider's support team may not be familiar with SGX-specific issues or configurations.
+ 5. **Hardware Provisioning:** If you use keys (such as SGX sealing keys) that are bound to hardware to encrypt the data of an instance within an Intel SGX enclave, the encrypted data cannot be decrypted after the host of the instance is changed.
