How does OptiTech help with TISAX?

Quick answer

OptiTech loads the ISA catalog with its maturity model: each control tracks current versus target maturity (not just pass-fail), scoped to the labels you're pursuing (high or very high protection needs, prototype protection, data protection). Cross-mapping from an existing ISO 27001 program covers most of the catalog immediately, the automotive-specific deltas arrive as a focused gap list, and the readiness view tells you honestly when to book the assessment provider.

Maturity scoring made visible

TISAX's distinctive mechanic is maturity: controls score from incomplete through established to optimizing, and your result must meet target maturity across the scope. The platform tracks the two numbers per control, and the gap analysis prioritizes by maturity distance, so effort lands where the assessment outcome moves. Evidence for maturity claims (process documentation, review cycles operating, continuous verification) accumulates in the same log the assessor will sample at AL2's plausibility review or AL3's on-site audit.

The automotive-specific deltas

Prototype and project protection: confidentiality controls around unreleased-product information: access scoping per project, physical and logical separation, and handling rules, tracked as controls with the project-scoped isolation they imply.
Customer-data segregation: OEMs care that their data is separated from their competitors'; the asset inventory documents per-customer data locations and the controls enforcing separation.
Supplier cascade: your own subcontractors touching automotive data need equivalent assurance, managed through the supplier register and questionnaires, the same flow-down the OEM applied to you.

From label to renewals

Labels last three years, with the assessment provider's findings tracked to closure as findings with owners. Because evidence collection never stops, the renewal assessment samples three years of operation instead of three weeks of preparation, and parallel demands (NIS 2 if you're in scope, customer questionnaires between assessments) draw from the same control set through the shared posture mechanics.
