Why Attestation Middleware Exists

What is Attestation Middleware? Attestation middleware is a software layer that sits between your applications and infrastructure, verifying trust claims about a system's identity, integrity, and security posture. Think of it as the bouncer at the door — but instead of checking IDs, it cryptographically proves that hardware, software, or an execution environment is exactly what it claims to be, running in a known and trusted state. What It Does Attestation is the process of proving that a system hasn't been tampered with. Middleware handles this verification so applications don't have to build it from scratch. Core functions: Identity verification — confirms a device or service is legitimat; Integrity measurement — checks that software and firmware haven't been modified (via cryptographic hashes and signatures); Evidence collection — gathers attestation reports from hardware roots of trust: TPM, Intel TDX, AMD SEV, ARM CCA; Policy enforcement — validates that a system meets the require
