NIST 800-171
U.S. standard protecting CUI in nonfederal systems
EN 1090
EU standard for steel and aluminium structural execution
Quick Verdict
NIST 800-171 protects CUI via cybersecurity controls for US contractors, while EN 1090 mandates CE marking through FPC for EU structural fabricators. Organizations adopt NIST for DoD contracts; EN 1090 for legal market access.

NIST 800-171 Details
What It Is
NIST SP 800-171 Revision 3 is a U.S. federal security framework for safeguarding Controlled Unclassified Information (CUI) confidentiality in nonfederal systems. It provides tailored, risk-commensurate requirements derived from NIST SP 800-53 Moderate baseline, applicable via contracts to contractors and supply chains.
Key Components
- 97 requirements organized into 17 families (e.g., Access Control, Audit, Supply Chain Risk Management).
- Built on FIPS 200 and SP 800-53 principles emphasizing confidentiality.
- Requires System Security Plan (SSP) and Plan of Action and Milestones (POA&M).
- Companion SP 800-171A r3 for examine/interview/test assessments.
Why Organizations Use It
- Mandatory for DoD via DFARS 252.204-7012; enables contract eligibility.
- Reduces CUI breach risks; supports CMMC Level 2.
- Builds stakeholder trust, competitive edge in federal markets.
Implementation Overview
- Phased: scope CUI enclave, gap analysis, implement controls, evidence collection.
- Targets contractors handling CUI; 6-36 months typical.
- Self or third-party assessments; ongoing monitoring essential.
EN 1090 Details
What It Is
EN 1090 is a harmonized European standard family (EN 1090-1/2/3) under the Construction Products Regulation (CPR). It governs conformity assessment and technical execution of structural steel and aluminium components/kits for construction works. Primary purpose: ensure safe fabrication, assembly, and market placement via CE marking. Adopts a risk-based approach through Execution Classes (EXC1–EXC4).
Key Components
- **EN 1090-1Conformity assessment, Factory Production Control (FPC), Declaration of Performance (DoP).
- **EN 1090-2/3Technical rules for steel/aluminium (materials, welding, tolerances, corrosion protection, NDT).
- Core: FPC certification by Notified Body, welding per ISO 3834, traceability, inspection scaled by EXC.
Why Organizations Use It
Mandated for EU/EEA market access via CE marking; reduces liability, ensures compliance. Drives risk management, quality consistency, rework reduction. Builds stakeholder trust, enables high-risk projects (bridges, stadia), competitive edge in tenders.
Implementation Overview
Phased: gap analysis, FPC build, personnel training (welding coordinators), NB certification, surveillance. Targets fabricators in construction; 6-12 months typical for medium firms. Requires audits, ITT/ITC.
