Eternis
Security attribution in trusted execution environments
Prior employer role — not a Saberistic client engagement.
Context
Eternis works on security attribution problems where workloads may run inside trusted execution environments (TEEs) with strict isolation requirements.
Problem
Attribution infrastructure had to reconcile security guarantees, attestation boundaries, and operational observability without weakening the TEE trust model.
Role
Principal Infrastructure Architect, Security Attribution & TEE
Intervention
Mapped trust boundaries between TEE workloads and surrounding services, defined attestation-aware deployment patterns, and scoped infrastructure changes that preserved attribution integrity.
Result
Delivered an infrastructure approach aligned to TEE constraints — giving teams explicit patterns for secure attribution rather than ad hoc integration.
