NIS2 DirectiveMandatory in EU · Oct 2024

NIS2 supply chain security
requires vendor assessments.

Under NIS2 Article 21(2)(d), entities in scope must address security in their supply chain — including the security practices of direct suppliers and service providers.

This means: your enterprise customers are legally required to assess your security posture. Sycrion gives you the external evidence to pass that assessment.

NIS2 Art. 21 — what Sycrion covers

NIS2 defines security requirements across 10 categories. External posture evidence is directly relevant to 3 of them. The other 7 require internal documentation.

·Art. 21(2)(a)Risk analysis and security policies

Requires internal policy documents — not covered by external scan

·Art. 21(2)(b)Incident handling

Internal process — not externally verifiable

✓Art. 21(2)(d)Supply chain security
Covered

External posture evidence covers what procurement checks in vendor supply chain reviews

✓Art. 21(2)(e)Security in network and information systems
Covered

HTTP security headers, CSP, HSTS, and system exposure directly checked

·Art. 21(2)(f)Authentication and access control

Internal access control — not externally verifiable

✓Art. 21(2)(h)Encryption and cryptographic standards
Covered

Full TLS/SSL grade via SSL Labs, cipher suite analysis, certificate chain

·Art. 21(2)(i)Human resources security and staff training

Internal HR process — not externally verifiable

✓ = covered by Sycrion external scan · · = requires internal documentation
