TISAX Consulting Services – Automotive Information Security Assessment Support

What TISAX Actually Does

TISAX evaluates the maturity of your information security practices against automotive-specific expectations.

It assesses:

• Information security controls

• Prototype protection

• Data protection and privacy

• Supplier security governance

• Organizational risk management

Assessment results are shared through the ENX portal with authorized partners.

This replaces repetitive customer audits with a standardized evaluation model.

Who Needs TISAX

TISAX applies to organizations operating within the automotive supply chain.

You likely need TISAX if you:

• Supply components or software to OEMs

• Handle confidential drawings or technical data

• Process prototype information

• Access development or production systems

• Store or manage sensitive supplier data

• Have contractual TISAX requirements

For many suppliers, this is a condition of doing business.

TISAX Assessment Levels

TISAX defines three Assessment Levels (AL).

AL1 — Self-Assessment

Used for lower-risk scenarios with limited sensitivity.

AL2 — Plausibility Check

Common for suppliers handling confidential information.

AL3 — High Availability and Critical Systems

Required for:

• Highly sensitive data environments

• Prototype protection requirements

• High availability or critical systems

Most OEM requirements fall under AL2 or AL3.

Correct scoping is critical before ENX registration.

TISAX vs ISO 27001

ISO 27001 provides the foundation.

TISAX applies automotive-specific expectations.

Key differences include:

• Use of the VDA ISA control catalog

• Automotive-specific maturity requirements

• Prototype protection modules

• ENX-recognized assessment providers

• Strong emphasis on supplier security governance

Organizations working with an ISO 27001 Consultant are typically well-positioned — but targeted alignment is still required.

For organizations integrating security into enterprise risk structures, see ISO Risk Management Consulting.

If it cannot be demonstrated, it will not pass.

ENX Portal and Scope Definition

We support:

• Scope definition and boundary setting

• Assessment Level determination

• ENX portal registration

• Coordination with assessment providers

Scope discipline prevents unnecessary cost and complexity.

Internal Audit and Pre-Assessment

We conduct structured pre-assessments to validate readiness.

This includes:

• Mock assessments

• Evidence validation

• Gap identification

• Leadership and team preparation

For organizations building audit capability, see ISO Internal Audit Services.

Common TISAX Gaps

Across automotive suppliers, recurring issues include:

• Incomplete or inconsistent risk documentation

• Weak supplier security oversight

• Insufficient objective evidence

• Informal prototype handling procedures

• Poor network segmentation design

• Lack of structured vulnerability management

We address these with practical, auditable controls.
