TISAX Certification – Automotive Information Security Consultancy

Meet industry security standards and win the trust of automotive OEMs with TISAX

TISAX (Trusted Information Security Assessment Exchange) is the recognised security assessment framework for the automotive sector, developed by the German Association of the Automotive Industry (VDA) and managed by the ENX Association. It is increasingly required by original equipment manufacturers (OEMs), Tier 1 suppliers, and mobility technology companies across Europe.

TISAX is based on ISO 27001 but introduces additional requirements tailored to the automotive supply chain. These include strict controls around prototype protection, data privacy, and secure information exchange. Organisations that handle sensitive customer data, vehicle design files, or engineering documentation must often achieve a TISAX label to access new business opportunities.

AvISO provides structured, practical support for organisations seeking to achieve and maintain a TISAX assessment. Whether you are a Tier 1 supplier, an engineering consultancy, or a technology partner working with OEMs, we help you understand the assessment requirements, define your scope, and prepare your system and team for successful evaluation.

What our clients say

“AvISO translated the complexity of VDA ISA into a manageable roadmap. With ISOvA, we had all policies, tasks, and evidence in one place. Our auditor commented on how mature and practical our system was — we couldn’t have done it without this support.”

Common TISAX challenges — and how we solve them

Many suppliers struggle with the practical and technical demands of TISAX. Common pain points include:

Uncertainty about the right label or scope – We help define your assessment objective, security level, locations, and expected outcomes
Lack of formal policies or procedures – We provide editable templates and support tailoring them to your operations
No dedicated security or compliance staff – We guide lean teams through implementation using structured plans and remote support
Overlap with ISO 27001 or other frameworks – We map and integrate existing systems to avoid duplication and reduce effort
Complex or unclear audit expectations – We prepare you step by step for the external assessment, including evidence, testing, and follow-up

Our consultants make the VDA ISA framework accessible and actionable, without compromising on technical rigour.

Integrated TISAX systems for better compliance

TISAX overlaps with many other frameworks, and integration can reduce duplication and cost. We typically integrate TISAX with:

ISO 27001 – Information security management
TISAX is fundamentally based on ISO 27001. If your organisation already has an ISMS, we help extend or tailor it to meet TISAX-specific controls such as prototype protection and data exchange requirements.
ISO 27701 – Privacy information management
TISAX assessments often include a privacy label. ISO 27701 provides the structure for privacy governance, data subject rights, and processing activities. Combined implementation strengthens GDPR alignment and supports international data transfers.
SOC 2 – Trust services reporting
For suppliers working across both automotive and cloud ecosystems, SOC 2 covers trust principles like confidentiality, availability, and privacy. We align overlapping controls and simplify audit preparation for both frameworks.
ISO 22301 – Business continuity management
TISAX requires controls around resilience, incident response, and disaster recovery. ISO 22301 formalises these requirements and ensures continuity for critical data systems and communications.
ISO 9001 – Quality management systems
Integrated management systems support consistent process delivery, documentation control, and risk-based thinking. This creates a more auditable and reliable control environment for both security and operational outcomes.
ISO 31000 – Risk management
Broader enterprise risk frameworks like ISO 31000 help contextualise information security within strategic and operational decision-making. We align TISAX risk assessments with existing registers to ensure board-level oversight.

Integrated systems reduce administrative overhead and demonstrate mature governance to OEM partners. With ISOvA, integration is seamless — data, evidence, and responsibilities are centrally managed and version-controlled.

ISO TISAX FAQs

Most frequently asked questions

What is TISAX, and who requires it?

TISAX (Trusted Information Security Assessment Exchange) is a security assessment scheme for the automotive sector, based on ISO 27001 and tailored by the VDA. It is required by major European OEMs and increasingly by their suppliers and partners.

Is TISAX the same as ISO 27001?

No. TISAX uses ISO 27001 as its foundation but introduces additional requirements around prototype protection, data privacy, and secure partner collaboration. It is assessed using VDA ISA criteria and published on the ENX portal.

Is TISAX a certification?

Not technically. You undergo an accredited assessment and receive a result (label) which is registered and published on the ENX portal. There is no physical certificate, but the label is considered equivalent for assurance purposes.

What are the TISAX labels?

TISAX labels cover areas like information security, data protection, and prototype protection. Labels also define the assessment level — from self-assessment (Level 1) to third-party audits with on-site verification (Level 3).

How long does TISAX take?

Most TISAX projects take 3 to 6 months, depending on the label scope, number of sites, and readiness level. Planning and preparation time can vary based on existing systems and documentation maturity.

Can we use ISO 27001 documentation for TISAX?

Yes, with adaptation. AvISO helps map your ISO 27001 controls to the VDA ISA requirements and close any gaps. Where additional controls are required, we provide templates and guidance to support implementation.

Do we need a privacy policy for TISAX?

Yes, if your label includes data protection. This typically requires documented data handling practices, subject access procedures, and compliance with regulations such as GDPR or CCPA.

What kind of evidence is required?

You will need documented policies, risk assessments, training records, audit logs, access control procedures, incident logs, and more. ISOvA makes this evidence traceable, version-controlled, and accessible.

Can TISAX be renewed or updated?

Yes. Labels are valid for three years. You can also update the label scope if your business changes or if OEM requirements expand. AvISO supports revalidation and scope changes.

Will AvISO support us during TISAX audit?

Absolutely. We help prepare documentation, coordinate with the auditor, and provide clarification throughout the process. Our aim is to make the audit smooth, professional, and successful.
