Vault and vaultless design
Assess where sensitive values, token mappings and lookup authority reside—and how vault or vaultless choices affect custody, recovery and operational risk.
PAYMENT TRUST BOUNDARIES
Design payment boundaries that can be explained and defended.
Independent architecture advisory for teams making consequential tokenization, key-management and payment-data protection decisions.
SPECIALIST ADVISORY
Cryptographic Tokenization Implementation Consulting
Tokenization is an architecture and operating-model decision, not a label applied to a data flow. We help define the boundary, the trust assumptions and the evidence needed to implement it with intent.
ARCHITECTURE QUESTIONS
Choose a token model with the whole control boundary in view.
Key protection where suitable
Define key-management responsibilities, protection requirements and separation points appropriate to the selected cryptographic design.
Controlled detokenization
Establish the narrow business purposes, authorization paths, logging expectations and operational controls for recovering sensitive value.
IMPLEMENTATION PATH
Turn a sound model into an operable deployment.
Architecture review connects the desired target state to integrations, migration constraints and proof that the controls work as designed. It is especially useful when payment platforms, legacy data stores and service providers meet at the same boundary.
- Map flows and trust pointsIdentify interfaces, custody transitions, data transformations and accountable owners.
- Plan integrations and migrationSequence cutover, coexistence, recovery and rollback considerations around the selected model.
- Define meaningful testsSpecify architecture, access, error-path and integration tests that show whether the intended boundary holds.
READINESS, NOT ATTESTATION
Prepare better evidence for PCI DSS conversations.
We can help teams examine the architecture, controls and documentation that may matter to PCI DSS readiness. A clear tokenization model can improve a security discussion, but it does not automatically reduce scope.
GC Solutions does not provide a PCI DSS attestation, certification, formal scope determination or QSA service. Your acquiring, assessor and compliance stakeholders retain their own responsibilities and decisions.
DECISION DISCIPLINE
Make trade-offs visible before production makes them permanent.
The output is an independent view of relevant design choices, evidence gaps, risks and next actions—not a claim that a payment environment is compliant or invulnerable.

YOUR NEXT STEP
Frame the payment-security decision before implementation hardens it.
Start with a high-level business conversation. Evidence handling, scope and operating boundaries come next.
