Know what is inside every ECU and what it means for vehicle cyber risk.
CRISKLE Supply Chain Tracking is built for automotive product security teams. It links ECU hardware, software components, SBOM evidence, and program-phase risk into one model so OEMs and Tier-1s can respond faster to new vulnerabilities, supplier issues, and field signals while maintaining traceability aligned to ISO/SAE 21434 and UNECE R155/R156.
Built to support automotive workflows: platform releases, ECU variants, PSIRT/CSMS governance, and lifecycle evidence packages.
Automotive-First Supply Chain Security
Built specifically for automotive product security teams linking ECU hardware, software components, SBOM evidence, and program-phase risk into one unified model.
Automotive Supply Chain Tracking (multi-tier, ECU-aware)
CRISKLE models the automotive supply chain as an ECU-centric graph—linking suppliers, sub-suppliers, software stacks, and build artifacts directly to ECU variants, vehicle programs, and release trains. This is not "generic IT inventory"; it is vehicle product security traceability.
- ECU bill of materials: SoC, comms components, secure elements, firmware images, configuration/policy artifacts.
- Program & variant mapping: platform, vehicle line, ECU variant, calibration/release references.
- Delivery evidence: supplier declarations, test and scan reports, release notes, security gates.
- Operational context: where the ECU is deployed (program, build window, service population where available).
SBOM ingestion (supplier-delivered or OEM-generated)
SBOMs can be provided by suppliers at ECU delivery or generated by the OEM/Tier-1 during development. CRISKLE treats SBOMs as evidence that powers vulnerability exposure and risk decisions across the lifecycle.
- SBOM packages mapped to ECU software images and variants
- Dependencies traced to specific releases
- Evidence chain preserved for PSIRT and governance
- Supports progressive maturity (coverage tracking + gap visibility)
Practical note: OEMs often receive SBOMs with varying quality; CRISKLE normalises and validates SBOM data to keep it usable for engineering.
Automotive workflow: SBOM → Vulnerability → Exposure → Risk → Engineering action
CRISKLE closes the loop by turning SBOM evidence into product security outcomes. Vulnerabilities discovered in SBOM packages are correlated to impacted ECUs and releases, then used to update risk posture and drive actionable remediation decisions.
Outputs for product security
- ECU risk posture: by program, variant, release, and deployment context.
- Prioritisation: focus on what is actually exposed, not what is hypothetically vulnerable.
- Evidence trail: what was known, when, and how remediation was validated.
- Supplier accountability: trace impacted components to upstream tiers.
Controls and mitigations
- Patch planning (hotfix vs next release train) and service strategy.
- Compensating controls (configuration hardening, policy updates, monitoring rules).
- Release gates (do not ship if evidence thresholds fail).
- Operational monitoring alignment (MSOC rules updated based on exposure).
From SBOM Evidence to Engineering Action
SBOMs can be provided by suppliers at ECU delivery or generated by the OEM/Tier-1 during development. CRISKLE treats SBOMs as evidence that powers vulnerability exposure and risk decisions across the lifecycle.
Vulnerability Analysis (SBOM-aware)
CRISKLE links SBOM components to vulnerability intelligence and keeps findings tied to ECU context.
- Find vulnerabilities per package and dependency chain
- Identify impacted ECU variants and releases
- Track status: detected → triaged → mitigated → verified
Risk Analysis + Asset Inventory Update
Vulnerability findings update asset risk ratings so engineering teams can act with up-to-date exposure information.
- Risk scoring aligned to lifecycle phase and operational exposure
- Asset inventory reflects current risk posture automatically
- Supports executive, engineering, and PSIRT reporting views
Automotive evidence & traceability
CRISKLE preserves the evidence chain connecting SBOM, vulnerabilities, risk decisions, and closure verification.
- Supplier SBOM stored as delivery evidence
- OEM SBOM linked to build pipeline artifacts
- Auditable decision trail for R155/21434 governance
Dynamic TARA
CRISKLE Dynamic TARA continuously updates threat scenarios, attack paths, and risk ratings as new information arrives—across program phases from concept and development to SOP and operations.
Dynamic TARA (continuous automotive threat & risk assessment)
CRISKLE Dynamic TARA continuously updates threat scenarios, attack paths, and risk ratings as new information arrives—across program phases from concept and development to SOP and operations. This ensures your risk model reflects the current landscape, not last quarter's assumptions.
- External disclosures and supplier notifications
- Internal engineering reports and validation findings
- SBOM-derived vulnerabilities and exposure changes
- MSOC detections and incident indicators from the field
- Threat scenarios mapped to affected assets and phases
- Risk ratings and exposures per ECU/program/release
- Mitigation requirements and verification evidence
- Decision dashboards for engineering and governance
CRISKLE MSOC connected to Dynamic TARA
Automotive cyber risk does not stop at SOP. CRISKLE MSOC provides operational monitoring signals that feed Dynamic TARA so risk posture reflects real-world exploitation attempts, anomalies, and incident indicators.
- Telemetry-driven reprioritisation (what is actually being targeted)
- Incident-to-engineering traceability for closure and verification
- Supports continuous compliance narratives for R155/R156 governance
From MSOC detections to PSIRT action
Once detections and telemetry arrive, CRISKLE can correlate them with asset and SBOM context to enable product-security action.
- Rules and alerts: correlation that understands ECU/program/release context
- PSIRT tickets: evidence + impacted assets attached by default
- Playbooks: guided steps (triage → mitigation → verification)
- Policy updates: governance-driven updates to monitoring and security policies (including ECU policy files)
Integration model: connect to existing ticketing/SIEM/SOAR tooling or operate natively within CRISKLE, depending on enterprise architecture.
Regulation-Aligned Visibility
Automotive programs need demonstrable control over components and ongoing risk handling—especially as requirements tighten around software supply chain transparency, vulnerability management, and operational monitoring.
UNECE R155 / ISO/SAE 21434

How OEMs and Tier-1s Benefit
CRISKLE Supply Chain Tracking delivers measurable outcomes for automotive product security teams across the supply chain.
How OEMs benefit
- Faster PSIRT answers: "which ECUs/releases are exposed?" with evidence.
- Program-level risk posture: exposure across platforms and vehicle lines.
- Supplier accountability: trace impacted components to upstream tiers.
- Better release decisions: risk gates aligned to SOP and aftersales realities.
- Audit confidence: consistent evidence for R155/R156 and internal governance.
How Tier-1s benefit
- Product security differentiation: deliver SBOM + posture with ECU deliveries.
- Reduced escalation churn: sub-supplier traceability limits unknown exposure.
- Aligned engineering response: one asset model across teams and programs.
- Customer trust: OEM-ready evidence packs for procurement and audits.
- Lower incident cost: focus on what is exposed in vehicles, not generic "CVE lists".
