TISAX Compliance and Readiness Services for Automotive OEMs & Suppliers
Protect high‑value automotive IP, reduce third‑party risk, and unlock access to new programs. Praetorian Secure guides OEMs and suppliers through VDA ISA gap assessment, TISAX Consulting, remediation, and ENX label sharing.
Why TISAX Compliance Matters in the Automotive Supply Chain
TISAX (Trusted Information Security Assessment Exchange) has become the de-facto information security benchmark for the automotive industry. It provides a common understanding of “what good looks like” for protecting sensitive OEM and supplier information, and a formal mechanism to prove that this level is achieved and maintained.
Standardized VDA ISA assessment recognized across OEMs and suppliers
TISAX is based on the VDA Information Security Assessment (VDA ISA), a standardized catalog of controls tailored to automotive needs. This means:
OEMs and suppliers work from the same set of information security requirements, rather than every customer inventing their own checklist.
Assessments are performed against a harmonized framework that aligns with ISO 27001 but adds automotive-specific topics (e.g., prototype handling, shopfloor / plant environments, development data).
Results are comparable: a TISAX label at a given assessment level (e.g., AL2 or AL3) means essentially the same thing for VW, BMW, Stellantis, or any other participating OEM.
This standardization reduces interpretation disputes (“what does ‘secure enough’ mean?”) and allows you to mature your controls once and leverage them across many customers.
Trusted exchange of results via the ENX portal to avoid redundant audits
TISAX is not just an assessment, it’s an exchange mechanism:
Assessment results are uploaded by the accredited audit provider into the ENX portal.
You decide which partners can see which scope and labels, instead of sending PDFs and reports by email.
OEMs and major Tier-1s rely on the portal instead of ordering their own proprietary security audits.
For suppliers, this means one properly scoped assessment can satisfy multiple customers, significantly reducing audit fatigue, travel, and preparation overhead. For OEMs, it provides a reliable, centrally governed source of truth about supplier security posture.
OEM procurement often requires a valid TISAX label
For many OEMs and large Tier-1s, TISAX has moved from “nice to have” to a hard requirement in procurement:
A valid TISAX label at the required assessment level is frequently a prerequisite to receive RFQs or to be onboarded as a supplier, especially where development data, connected vehicle services, or prototype work are involved.
Expired labels or missing scopes can delay awards, trigger corrective action requests, or even block business.
Having an appropriate TISAX label already in place positions your company as “low friction” to do business with and can provide a competitive advantage in tight supplier selections.
Stronger protection of prototypes and intellectual property (IP)
The automotive industry has a very high sensitivity to leaks involving:
Prototypes and test vehicles
New design concepts and CAD data
Powertrain, software, and feature IP
Launch-critical manufacturing and quality data
Moreover, TISAX explicitly includes assessment objectives and labels for prototype protection and, where applicable, data protection. These drive concrete controls such as secure areas, access control, handling rules for test vehicles and parts, restrictions on photography, protection of digital design data, and secure collaboration with external partners. Implementing these controls not only satisfies OEM expectations but materially reduces the risk of IP loss, brand damage, or regulatory issues arising from leaks or incidents.
Business impact of TISAX Compliance for our organization
For us, TISAX is not just a compliance badge—it is the framework we are using to structure our readiness and assessment program, define clear milestones (gap assessment, POA&M, technical controls, internal audit, mock audit), and demonstrate to OEMs and key customers that we manage information and prototypes to an industry-accepted standard.
Suppliers & Partners (Examples)
- Tier 1 & Tier 2 suppliers
- Engineering & testing partners
- IT / Cloud service providers
- Logistics & prototype handlers
Access & Environments
- Tooling & manufacturing partners
- Systems integrators
- Prototyping environments
- Organizations accessing OEM networks

TISAX Assessment Levels
| Level | Use Case | Assessment Type |
|---|---|---|
| AL1 | Lower sensitivity, internal-only contexts | Self‑assessment |
| AL2 | Confidential information handling | Accredited audit |
| AL3 | High‑value IP & prototype protection | On‑site assessment |
TISAX uses three TISAX assessment levels to define how deeply your information security is checked and how much trust other participants can place in the result.
AL1 – Assessment Level 1: Self-Assessment
What it is:
- Pure self-assessment based on the VDA ISA questionnaire.
- No accredited audit provider, no on-site audit.
How it’s done:
- You answer the ISA questions internally and document your implementation and maturity.
- No external validation of your answers.
When it’s used:
- For information with low protection needs.
- Often used internally as a first maturity check or starting point before aiming for AL2/AL3.
- Usually not accepted by OEMs as formal proof of security for sensitive projects.
What it proves (and what it doesn’t):
- Shows that you’ve thought about information security and performed basic self-checking.
- But: because there is no independent review, it offers limited assurance to customers.
AL2 – Assessment Level 2: Standard On-Site Assessment
What it is:
- Assessment performed by an accredited TISAX audit provider.
- Includes documentation review plus either:
- remote / interview-based verification, or
- on-site audit, depending on the scope and protection needs.
How it’s done:
- You complete the ISA self-assessment first.
- The audit provider reviews:
- Policies and procedures
- Technical and organizational controls
- Selected evidence (logs, screenshots, records, etc.)
- They conduct interviews with key roles (IT, security, HR, operations, management).
- They verify implementation at a sample of locations / systems.
When it’s used:
- For information with “high” (normal) protection needs – e.g. standard development data, non-public technical details, typical OEM–supplier collaboration data.
- This is the most common level requested in OEM purchasing requirements.
What it proves:
- Your ISMS and controls are implemented and effective at a normal level of rigor.
- Provides credible, recognized assurance across the TISAX network.
- Typically accepted by OEMs for many business scenarios, as long as the scope fits.
AL3 – Assessment Level 3: Enhanced, Very High Protection Needs
What it is:
- The most intensive type of TISAX assessment.
- Focused on information with “very high” protection needs, especially:
- Prototypes / test vehicles / design prototypes
- Highly sensitive IP and strategic development data
- Safety-/security-critical systems or data
How it’s done:
Compared to AL2, AL3 has more depth and rigor:
- Stronger evidence requirements
- More detailed documentation and records
- More sampling of real cases (change tickets, access approvals, incident records, vendor evaluations, etc.)
- More intensive on-site work
- Physical inspection of offices, labs, workshops, prototype areas, and test tracks where applicable
- Verification of physical security, access control, surveillance, secure storage, clean desk/clear screen, handling of test vehicles and parts.
- Broader and deeper interviews
- Not just ISMS and IT – also engineering, plant operations, prototype build & logistics, test departments, etc.
- Focus on how rules work in practice, not just on paper.
- Higher expectation for maturity
- Controls must not only exist, but be consistently applied, monitored, and improved.
- Clear risk management, regular internal audits, management reviews, KPIs, and continuous improvement.
When it’s used:
- Required when:
- OEMs or Tier-1s classify the shared information/prototypes as “very high” protection need, or
- Prototype protection labels are requested (e.g., handling real vehicles, parts, or confidential design mock-ups).
Often a precondition for direct prototype work with major OEMs (camouflage vehicles, secret test campaigns, etc.).
What it proves:
- You operate a highly mature security environment, especially for:
- Prototype and IP protection
- Physical security and access control
- Strict handling of sensitive information across the full lifecycle
- Gives OEMs the confidence to entrust you with their most sensitive assets.
Simple Comparison Summary
You can summarize AL1–AL3 like this:
AL1 – “We checked ourselves.”
- Self-assessment only
- Low assurance, mostly internal use
AL2 – “An accredited auditor confirmed we’re secure.”
- External assessment, document + interview/onsite
- Standard level for most OEM requirements
AL3 – “An accredited auditor tested us very thoroughly for high-risk topics.”
- Enhanced, deep on-site review and strong evidence
- Needed for very high protection needs, especially prototypes/IP
