Cloud Service Provider Security

To meet the Cloud Service Provider Security requirement in VDA ISA 4.3.1, you must assess and manage information security risks before and during any use of a cloud service provider that processes or stores confidential automotive data, then enforce protections through contracts and technical controls. Operationally, this means documented due diligence, clear security requirements (including encryption and residency where relevant), and ongoing oversight. (VDA ISA Catalog v6.0)

Key takeaways:

• You need a repeatable cloud third-party risk process tied to data classification and workload criticality. (VDA ISA Catalog v6.0)
• Contracts must carry enforceable security, audit, incident notification, and data handling terms, not just a generic MSA. (VDA ISA Catalog v6.0)
• Evidence matters: assess, approve, configure, monitor, and re-review, and retain artifacts that prove each step. (VDA ISA Catalog v6.0)

“Cloud Service Provider Security” under VDA ISA 4.3.1 is a requirement-level expectation: if confidential automotive data touches a cloud service provider, you must treat that provider like a high-impact third party and actively manage the risk. The standard is not asking whether cloud is “allowed.” It asks whether you can prove you evaluated the cloud provider’s security posture, set binding requirements, and implemented controls that match the sensitivity of the automotive data involved. (VDA ISA Catalog v6.0)

For a CCO, GRC lead, or security/compliance owner preparing for TISAX-related assessments, the fastest path is to operationalize a single workflow that connects: (1) data classification, (2) cloud provider due diligence, (3) contracting, (4) secure configuration, and (5) continuous oversight. Auditors will look for consistency: the same type of cloud use case should trigger the same minimum set of checks and evidence every time. (VDA ISA Catalog v6.0)

This page translates the requirement into a practical checklist you can run for common scenarios (SaaS file sharing, cloud storage buckets, hosted CI/CD, managed databases, CRM with customer engineering data), plus the artifacts to retain so you can answer assessor questions without rebuilding the story from memory.

Regulatory text

Requirement (excerpt): “Assess and manage information security risks when using cloud service providers for processing or storing confidential automotive data.” (VDA ISA Catalog v6.0)

What the operator must do

You must:

1. Identify cloud service provider use where confidential automotive data is processed or stored. (VDA ISA Catalog v6.0)
2. Assess information security risk of that cloud service provider and the specific cloud service/workload. (VDA ISA Catalog v6.0)
3. Manage the risk through contractual protections, data residency compliance where relevant, and encryption requirements that are implemented and enforced. (VDA ISA Catalog v6.0)
4. Maintain ongoing control so the assessment stays true as services, configurations, and sub-processors change. (VDA ISA Catalog v6.0)

Plain-English interpretation (what this means in practice)

If confidential automotive data is in the cloud, you need proof that:

• You knew it was there (inventory + data classification).
• You checked the provider and service risks (not just trust marketing claims).
• You wrote the security rules into the deal (contract + DPA + security addendum).
• You configured the service to meet those rules (encryption, access controls, logging).
• You monitor and re-check over time (drift, new features, sub-processors, incidents). (VDA ISA Catalog v6.0)

Who it applies to

Entity types

• Automotive suppliers
• OEMs (VDA ISA Catalog v6.0)

Operational context (triggers)

Apply this requirement when a cloud service provider (SaaS/PaaS/IaaS or managed services) will:

• Store confidential automotive information (design data, test results, pricing, sourcing, production planning, customer engineering data, etc.).
• Process that data (analytics, collaboration, CI/CD pipelines, ticketing systems containing sensitive attachments). (VDA ISA Catalog v6.0)

A common miss: teams treat “internal productivity SaaS” as out-of-scope. If confidential automotive data can be uploaded or synced, it is in scope. (VDA ISA Catalog v6.0)

What you actually need to do (step-by-step)

Step 1: Build a scoped cloud register tied to confidential data

Create and maintain a list of cloud service providers that can touch confidential automotive data:

• Provider name, service name, business owner, and intended use case.
• Data types involved and classification (flag “confidential automotive data” explicitly).
• Where data is stored/processed (as contractually agreed and as configured).
• Sub-processors (if the provider uses them for delivery of the service). (VDA ISA Catalog v6.0)

Operator tip: start with your SSO app catalog, finance SaaS spend, and DNS/proxy logs to find shadow cloud use.

Step 2: Perform due diligence that matches the use case

Document a risk assessment that covers:

• Security posture of the provider and the specific service you will use. (VDA ISA Catalog v6.0)
• Data handling and residency expectations for the confidential automotive data involved. (VDA ISA Catalog v6.0)
• Encryption requirements (in transit, at rest, key management expectations) and whether the service supports them in the way you intend to configure it. (VDA ISA Catalog v6.0)
• Access control model: identity integration, MFA, least privilege, admin roles, break-glass access.
• Logging and monitoring: what telemetry exists, retention, export to SIEM, admin/audit logs.
• Incident response: how you receive notifications, what evidence the provider will share.
• Exit/portability: ability to retrieve data, confirm deletion, and manage end-of-service risk.

Keep the assessment short but specific. “Reviewed SOC report” is not a risk assessment. Tie findings to your workload and data. (VDA ISA Catalog v6.0)

Step 3: Translate assessment results into enforceable contract terms

Minimum contract components to operationalize VDA ISA 4.3.1:

• Security obligations: baseline controls the provider must maintain for the service in scope. (VDA ISA Catalog v6.0)
• Confidential data processing terms: permitted purposes, handling, retention, deletion, and restrictions on use. (VDA ISA Catalog v6.0)
• Audit and assurance: right to receive assurance materials and defined cooperation for assessments.
• Incident notification and cooperation: notification triggers, timing expectations, investigation support, evidence availability.
• Sub-processor controls: disclosure, change notification, and flow-down obligations.
• Data residency/processing location: commitments aligned to your requirements for confidential automotive data. (VDA ISA Catalog v6.0)
• Encryption commitments: required encryption states and any customer-managed key expectations where applicable. (VDA ISA Catalog v6.0)

Practical approach: use a “cloud security addendum” template with selectable clauses based on data classification and service type (SaaS vs IaaS). That prevents one-off negotiating and reduces gaps. (VDA ISA Catalog v6.0)

Step 4: Implement technical controls and guardrails in the cloud service

Contract promises do not satisfy the requirement if your configuration contradicts them. Implement:

• Encryption configuration aligned to your policy and the service’s options (for storage, backups, exports). (VDA ISA Catalog v6.0)
• Identity and access controls: SSO, MFA, role-based access, least privilege admin roles, periodic access reviews.
• Segmentation and tenant controls (where applicable): separate environments for confidential workloads; restrict sharing and external collaboration.
• Logging: enable admin logs, access logs, and alerts for risky events (mass downloads, new OAuth apps, new admins).
• Data loss guardrails: restrict public links, external sharing, unmanaged devices, and exports where appropriate.
• Configuration monitoring: detect drift from required settings.

Document the “minimum secure configuration” per provider/service and require teams to attest to it before go-live. (VDA ISA Catalog v6.0)

Step 5: Ongoing oversight (don’t treat approval as permanent)

Operationalize oversight:

• Re-review the provider when there is a material change: new service, new region, new sub-processor, incident, or major contract renewal. (VDA ISA Catalog v6.0)
• Monitor for unauthorized use of cloud services that can store confidential data.
• Track exceptions (who approved, compensating controls, expiration, and follow-up action).
• Test exit: can you export data and confirm deletion as required?

If you use Daydream to run third-party due diligence workflows, set up a dedicated “Cloud service provider security” intake that forces consistent scoping (data type, service model, residency needs), then produces a standard evidence pack for assessors. Keep the workflow lightweight so teams do not route around it.

Required evidence and artifacts to retain

Keep artifacts mapped to the lifecycle so you can prove “assess and manage” with minimal back-and-forth:

Governance and scoping

• Cloud service provider inventory/register (in-scope for confidential automotive data).
• Data classification standard and criteria for “confidential automotive data.” (VDA ISA Catalog v6.0)

Due diligence and risk management

• Completed cloud provider risk assessment ¹.
• Risk treatment record: accept/mitigate/avoid/transfer decisions and approvals.
• Exceptions register with compensating controls and expiration. (VDA ISA Catalog v6.0)

Contracting

• Executed MSA/DPA/security addendum with required clauses (residency, encryption, incident notification, sub-processors). (VDA ISA Catalog v6.0)

Technical implementation

• Secure configuration baseline per cloud service (documented settings).
• Evidence of configuration: screenshots, exported settings, policy objects, IaC snippets.
• Logging/alerting enablement evidence and integration records (if applicable). (VDA ISA Catalog v6.0)

Ongoing oversight

• Review cadence record tied to material changes (change tickets, renewal reviews).
• Provider communications about sub-processor or service changes, and your response. (VDA ISA Catalog v6.0)

Common exam/audit questions and hangups

Assessors commonly probe:

• “Show me all cloud services that store confidential automotive data.”
• “How do you decide whether a cloud provider is acceptable for this data type?” (VDA ISA Catalog v6.0)
• “Where is data stored and processed, and how do you know?” (VDA ISA Catalog v6.0)
• “Prove encryption is required and enabled for this service.” (VDA ISA Catalog v6.0)
• “What contract clauses guarantee incident notification and sub-processor control?”
• “How do you detect and stop teams from onboarding unsanctioned cloud tools?”

Hangup to expect: you have contracts and policies, but no proof that tenant settings match them. Bring configuration evidence.

Frequent implementation mistakes (and how to avoid them)

1. Assessing only the provider, not the workload. Fix: scope the assessment to the specific service and data flows. (VDA ISA Catalog v6.0)
2. Relying on a generic MSA. Fix: require a security addendum/DPA with explicit data handling, residency, and encryption terms. (VDA ISA Catalog v6.0)
3. “Encryption required” written, but not configured. Fix: define minimum secure configuration and validate before go-live. (VDA ISA Catalog v6.0)
4. No sub-processor visibility. Fix: contract for disclosure and change notification; track sub-processors for in-scope services.
5. Shadow SaaS. Fix: monitor SSO and spend, block unknown apps where feasible, and create a fast intake path so teams comply. (VDA ISA Catalog v6.0)

Risk implications (why assessors care)

Cloud services expand your attack surface and create concentration risk: one compromised tenant, misconfiguration, or provider incident can expose confidential automotive data across programs and customers. VDA ISA 4.3.1 pushes you to show disciplined control over that risk through repeatable assessment, enforceable terms, and validated technical settings. (VDA ISA Catalog v6.0)

Practical execution plan (30/60/90)

First 30 days (stabilize and scope)

• Stand up the cloud provider register for confidential automotive data and name business owners.
• Publish a minimum required intake: data type, service model, residency needs, encryption needs.
• Freeze new cloud onboarding for confidential automotive data unless it goes through the intake and approval workflow. (VDA ISA Catalog v6.0)

Next 60 days (standardize and remediate)

• Create the cloud security addendum/DPA language your legal team can reuse.
• Define minimum secure configuration baselines for your top cloud services (start with the ones already used for confidential data).
• Remediate the highest-risk gaps: public sharing, weak admin controls, missing logs, unclear residency commitments. (VDA ISA Catalog v6.0)

By 90 days (operationalize continuous oversight)

• Implement monitoring for new cloud app onboarding (SSO catalog, finance approvals, or CASB/proxy signals).
• Add renewal and change-trigger reviews (sub-processor change, new region, new service).
• Package evidence: for each in-scope provider, maintain a single folder with assessment, contract, and configuration proof ready for a TISAX assessor. (VDA ISA Catalog v6.0)

Frequently Asked Questions

Does this apply to SaaS tools like file sharing and ticketing, or only IaaS cloud hosting?

It applies to any cloud service provider used to process or store confidential automotive data, including SaaS. Scope follows the data, not the hosting model. (VDA ISA Catalog v6.0)

What counts as “assess and manage” in a way an assessor will accept?

You need documented due diligence, a recorded risk decision, and evidence that required protections are contractually binding and technically enforced. Keep artifacts tied to the specific service and use case. (VDA ISA Catalog v6.0)

How do we handle data residency if the cloud provider has global infrastructure?

Define residency needs for the confidential automotive data in scope, require those commitments in the contract, and configure the service to restrict regions where possible. Retain both the contractual commitment and configuration evidence. (VDA ISA Catalog v6.0)

Is encryption always required?

VDA ISA 4.3.1 expects encryption requirements to be enforced for confidential automotive data in cloud services. Your job is to specify what “encryption required” means for the service and prove it is enabled. (VDA ISA Catalog v6.0)

What if the business insists on a cloud provider that cannot meet one requirement?

Run an exception process with a clear risk acceptance decision, compensating controls, and an expiration date tied to a remediation plan or exit. Treat the exception record as an audit artifact. (VDA ISA Catalog v6.0)

How do we keep teams from bypassing the process with shadow IT?

Make the approved path fast (standard intake and pre-approved providers) and add detection through SSO app catalogs and procurement controls. If the process is slow, teams will route around it. (VDA ISA Catalog v6.0)
