A vulnerability in a safety-critical ECU is not a data breach. It is a recall.
Black Duck finds vulnerabilities in ECU firmware before they become CVE headlines. Siemens Polarion proves they were governed. X-DLM™ keeps the TARA evidence alive for the lifetime of the vehicle.

In automotive, a security failure is a safety failure — and UN R155 requires continuous evidence of prevention.

Known vulnerabilities in Black Duck's KnowledgeBase — including BDSA advisories for automotive RTOS, AUTOSAR, and embedded cryptographic libraries up to 3 weeks ahead of NVD.
UN R155 and ISO 21434 require post-development cybersecurity monitoring for the operational life of the vehicle — including vehicles already on the road with components that carry newly discovered CVEs.
Acceptable undisclosed cybersecurity incidents under UN R155. Every significant cybersecurity incident must be reported to the Type Approval Authority and logged in the CSMS record.

Monitor ECU component risk across the vehicle lifetime
Black Duck continuously monitors the vehicle SBOM against new CVE disclosures — including BDSA advisories up to 3 weeks ahead of NVD. When a new vulnerability affects a component in a production vehicle's firmware, X-DLM™ triggers a TARA risk recalculation in Polarion and routes a governed response workflow to the responsible engineer — automatically.
- 02
Govern the full ISO 21434 post-development response chain
X-DLM™ routes every vehicle vulnerability finding through the ISO 21434-aligned response process: triage → TARA impact assessment → risk acceptance or remediation decision → OTA update or recall evaluation → sign-off and evidence retention. Every step is timestamped, traceable, and available for CSMS audit review.
- 03
Supplier vulnerability evidence — not just supplier declarations
49.5% of automotive attacks exploit software system vulnerabilities. Most originate in supplier-provided ECU firmware with undisclosed open-source components. Black Duck binary scanning of supplier deliveries reveals what the supplier's SBOM didn't declare — giving OEMs the actual risk picture their CSMS certification requires.

UN R155 incident reporting — governed and auditable
UN R155 Annex 5 requires OEMs to report significant cybersecurity incidents to the Type Approval Authority. X-DLM™ maintains the incident classification, evidence of response action, and remediation outcome record in Polarion — producing the CSMS documentation that satisfies both the reporting obligation and the ongoing CSMS audit trail.

What X-DLM™ changes for your business
Security runs itself.Your teams focus on product innovation.
Before
Security as a release bottleneck
Manual triage, fragmented tools, late-cycle surprises. Security gates slow delivery and drain engineering bandwidth.
After X-DLM™
Automated vulnerability handling from detection to remediation. Engineers stay focused on building — security runs in parallel, not as a checkpoint.
Before
Security bolted on at the end
Reactive posture. Vulnerabilities discovered late. Costly rework. Customers and auditors see through it.
After X-DLM™
Secure by design from day one. Black Duck SCA monitors every component continuously — source, binaries, firmware, and AI-generated code — before it ships.
Before
Compliance as recurring overhead
Engineers pulled into audit prep. Legal scrambling for evidence. Weeks of work per assessment. Repeatable cost with no revenue return.
After X-DLM™
Evidence generated and timestamped continuously via Polarion LiveDocs. Audit prep drops 60–80%. What took weeks takes hours — without touching engineering.
Before
Security as a cost story in sales
Enterprise buyers in regulated markets want proof of security maturity. Without it, deals stall, diligence cycles extend, and contracts go to competitors who have it.
After X-DLM™
100% traceable, audit-ready cybersecurity proof — with Siemens and Black Duck behind it. Your sales team closes faster. Your brand commands a premium.
Automotive cybersecurity obligations cascade from OEM to every Tier in the supply chain.
UN R155 holds the OEM responsible for CSMS evidence across the entire vehicle — but Tier 1 suppliers must provide cybersecurity interface agreements, TARA evidence, and SBOM data to support that obligation. ISO/SAE 21434 governs the engineering process at every tier. A Tier 2 supplier without ISO 21434-aligned processes is a risk that lands in the OEM's type approval file.

X-DLM™ connects Black Duck's ECU vulnerability and SBOM intelligence to Siemens Polarion's ISO 21434 lifecycle management — so your automotive security team can produce continuous CSMS evidence, TARA-linked vulnerability records, supplier security documentation, and UN R155 incident evidence on demand.
