# Intel SGX (Software Guard Extensions)
> Intel Software Guard Extensions (SGX) is a set of security-related instruction codes built into some Intel central processing units (CPUs). It allows user-level code to allocate private regions of memory, called enclaves, which are protected from processes running at higher privilege levels.

## Buyer Intent Signals
Problems: Manual CPU Management: Writing foundational code directly for CPU rings without specific enclave abstractions. | Standard Cloud Virtualization: Trusting the hypervisor and OS integrity without hardware-level isolation.
Solutions: What is an Intel Enclave? | How to protect data in use in the cloud? | Trusted Execution Environment hardware list | Confidential computing solutions for Xeon | How to enable SGX on 13th Gen Intel Core? | Hardware Security Modules (HSM): Using specialized chips or hardware security modules to store keys and perform operations outside the main CPU. | AMD SEV (Secure Encrypted Virtualization): Running sensitive workloads in AMD's competing hardware-based encryption environment.
