Full-Stack Verification

Silicon to runtime attestation

Attester delivers continuous cryptographic proof across bare-metal firmware, hypervisors, confidential enclaves, and autonomous model weights. Execution halts instantly whenever running state diverges from reference values.

Architectural Tiers

Four layers of verifiable proof

Tier 01

Silicon Root-of-Trust

Interrogates hardware TPM registers, cryptographic fuses, and UEFI configurations before the kernel boot sequence executes. System launch halts if measurements diverge from immutable golden reference manifests.

Tier 02

Operating Systems and Kernels

Validates immutable kernel structures, boot loaders, and virtualization hypervisors to prevent pre-boot rootkits and firmware memory manipulation. Every hypervisor transition records a verifiable cryptographic signature.

Tier 03

Confidential Compute Enclaves

Maintains hardware-isolated memory attestation within AMD SEV-SNP and Intel TDX enclaves across hybrid clouds. Validates runtime enclave integrity continuously without exposing sensitive in-memory plaintext.

Tier 04

Autonomous Agent Execution

Monitors inference runtime parameters, weights integrity, and memory execution state to detect agent context injection and unauthorized model alteration. Guarantees deterministic cognitive agent behavior across production pipelines.

Cognitive Layer

Model provenance and weight integrity

Attester generates continuous mathematical signatures over active model weights, retrieval context buffers, and system prompt parameters. Any unauthorized parameter drift or in-memory injection halts execution immediately.

Enterprise agent runtimes execute with cryptographic verification records logged to immutable audit streams. Platform engineering teams verify pipeline provenance across multi-cloud clusters and sovereign infrastructure.
