About Tierex
Collect evidence once. Keep it trusted. Reuse it wherever it is needed.
TIEREX Ltd. helps defense contractors and compliance teams turn scattered documentation into organized, audit-ready evidence. The platform creates a structured evidence layer that connects documents, controls, and requirements in one place.
Teams can identify gaps earlier, maintain traceability, and stay continuously ready instead of rebuilding proof before every assessment. Tierex is built initially for CMMC Level 1 and Level 2 and NIST SP 800-171.
The problem
Your security may be strong. Proving it should not be the hardest part.
Policies, configurations, logs, and supporting records often live across many systems. Finding the right version, proving that it is current, mapping it to requirements, and presenting it consistently consumes engineering time and introduces avoidable risk.
Tierex brings evidence, integrity, mappings, and review history into one traceable workflow so teams can prepare with clarity rather than scramble before an assessment.
How it works
One evidence layer from collection to review.
Reduce repeated preparation work, improve consistency, and give your compliance team a clear source of truth for every piece of evidence.
Structured collection
Bring approved system records and uploaded evidence into a consistent workflow.
Integrity and lineage
Preserve source, version, ownership, time, and a verifiable history of change.
Evidence mapping
Connect exact evidence versions to controls and assessment objectives.
Readiness tracking
Review coverage, surface gaps, and maintain deterministic SPRS inputs.
