NIS2 supply chain evidence should build itself. Not scramble before every audit.
One governed system. NIS2, EU CRA, and GSMA NESAS evidence produced continuously — not assembled under time pressure before each compliance deadline.
Telecom compliance teams carry the most multi-framework documentation burden in regulated software. NIS2 Article 21 supply chain security measures are manually documented pre-audit. EU CRA SBOM is a new product obligation most compliance teams have not yet operationalized. GSMA NESAS lifecycle documentation is assembled for each audit cycle. Operator qualification evidence is rebuilt for every RFP.
X-DLM™ makes all of it a byproduct of how your engineering team already works — not an emergency before every audit and qualification cycle.
and
Requires documented supply chain security measures for Essential Entities and their software suppliers — including vulnerability management, software composition documentation, and supply chain risk assessment. Evidence must exist before audit, not be assembled during it.
NIS2 Article 23 incident reporting cascade: 24-hour early warning, 72-hour incident notification, 30-day final report to national CSIRT. The evidence that governs this timeline is the same supply chain documentation X-DLM™ produces continuously.
EU CRA vulnerability reporting obligations apply from September 11, 2026. Actively exploited vulnerabilities must be reported to ENISA within 24 hours. X-DLM™ tracks BDSA-flagged exploited vulnerabilities with ENISA deadline management in Polarion.
GSMA NESAS Product Development & Lifecycle Management Process Audit evaluates 20 security requirements. Siemens Polarion provides the system of record that NESAS auditors are trained to evaluate. X-DLM™ connects Black Duck findings into the same trail.
What X-DLM™ automates for telecom compliance teams
NIS2 Article 21 supply chain documentation — continuous, audit-ready
X-DLM™ connects Black Duck supply chain findings to Siemens Polarion governance records — so NIS2 Article 21 supply chain security measures documentation builds continuously during development. Supply chain risk assessments, vulnerability handling records, and software composition documentation exist before any national cybersecurity authority audit. Compliance teams review and approve — they do not reconstruct.
EU CRA SBOM — machine-readable, version-controlled, before the reporting obligation fires
Black Duck generates machine-readable SBOM in SPDX and CycloneDX for EU CRA Annex I minimum elements. X-DLM™ version-controls every SBOM in Polarion — linked to the release it represents and updated with every build. EU CRA requires this SBOM to exist before a vulnerability reporting event. X-DLM™ ensures it does.
GSMA NESAS lifecycle documentation — built during development, not for the audit
GSMA NESAS requires documentation of the product development lifecycle including software composition management, vulnerability handling process, and secure development practices. Siemens Polarion provides the lifecycle system of record NESAS auditors evaluate. X-DLM™ routes Black Duck findings into Polarion so NESAS lifecycle documentation is a byproduct of normal engineering activity — not an audit preparation project.
Operator qualification packages — on demand, not on deadline
Telecom operators requiring SBOM and supply chain security evidence for vendor qualification receive a current, Polarion-linked documentation package from X-DLM™ — not a pre-RFP reconstruction. The difference between telecom software vendors that win operator qualifications and those that miss them is not the security posture. It is the evidence that was continuously maintained versus the evidence that was assembled under deadline.
Telecom companies answer to more than one framework — simultaneously
NIS2 is the floor, not the ceiling. EU CRA, GSMA NESAS, ETSI EN 303 645, 3GPP SA3, and IEC 62443 run in parallel — each with its own evidence requirements, its own reporting deadline, and its own consequence for missing supply chain documentation.

X-DLM™ connects Black Duck's vulnerability, malware, and SBOM intelligence to Siemens Polarion's governed workflows — so your compliance team can produce NIS2 Article 21 evidence, EU CRA SBOM, GSMA NESAS documentation, and operator qualification packages on demand.
