ISO 37001 Details
What It Is
ISO 37001:2025 Anti-Bribery Management Systems is an international certifiable standard for establishing, implementing, and improving an Anti-Bribery Management System (ABMS). It focuses on preventing, detecting, and responding to bribery risks across organizations, using a risk-based, proportionate approach aligned with PDCA (Plan-Do-Check-Act) and Harmonized Structure for integration.
Key Components
- Core clauses 4-10 cover context, leadership, planning, support, operations, evaluation, improvement.
- Key controls: anti-bribery policy, risk assessments, third-party due diligence, financial/non-financial controls, training, reporting/investigations.
- Built on leadership accountability, culture, and documented evidence.
- Optional third-party certification with audits.
Why Organizations Use It
- Mitigates legal risks (e.g., FCPA, UK Bribery Act) via evidentiary "reasonable steps".
- Enhances reputation, stakeholder trust, ESG alignment.
- Drives efficiencies (up to 15% compliance cost reduction), operational controls.
- Competitive edge in tenders, high-risk sectors.
Implementation Overview
- Phased: gap analysis, risk assessment, controls design, training, audits.
- Scalable for all sizes/sectors; 6-12 months typical.
- Involves leadership commitment, third-party focus; certification via accredited bodies.
NIST 800-171 Details
What It Is
NIST Special Publication (SP) 800-171 Revision 3 is a U.S. cybersecurity framework for safeguarding the confidentiality of Controlled Unclassified Information (CUI) in nonfederal systems and organizations. It provides recommended security requirements for federal contractors, tailored from NIST SP 800-53 Moderate baseline using a control-based, risk-commensurate approach.
Key Components
- 97 requirements across 17 families, including Access Control, Audit, new additions like Supply Chain Risk Management (SR) and Planning (PL)
- Core artifacts: System Security Plan (SSP), Plan of Action and Milestones (POA&M)
- Assessment procedures via SP 800-171A r3 (examine/interview/test); aligns with FIPS 200
- Compliance model: self-assessment, third-party audits (e.g., CMMC Level 2), SPRS scoring
Why Organizations Use It
- Mandatory via DFARS 252.204-7012 for DoD contractors handling CUI/CDI
- Ensures contract eligibility, reduces breach risks, enhances resilience
- Builds federal agency trust, competitive procurement advantage
Implementation Overview
- Phased: scoping CUI enclave, gap analysis, controls, evidence collection, monitoring
- Suits all sizes in federal supply chains; documentation-intensive
- No universal certification; contract-driven audits required (180 words)
