Cybersecurity risk assessment for international business
A practical framework for identifying, evaluating, and prioritizing cyber risks across global operations, regulations, and supply chains.
For multinational organizations, cybersecurity risk assessment is more than a compliance checklist. It is the foundation for deciding where to invest, what to protect first, and how to align security with business strategy. This guide outlines the approach we use with clients to turn risk assessment into a repeatable management discipline.
The process
Six steps to a defensible risk assessment
Define the scope
Start by mapping the business units, geographies, systems, and third parties that will be included. A clear scope prevents the assessment from becoming unwieldy and ensures the results are actionable for decision-makers.
Identify international exposures
Document cross-border data flows, cloud regions, local regulatory obligations (GDPR, DORA, NIS2, SEC cyber rules), and geopolitical considerations. Each jurisdiction adds its own threat landscape and compliance requirements.
Catalog threats and vulnerabilities
Use recognized frameworks such as MITRE ATT&CK, NIST CSF, and ISO 27005 to identify threats. Pair each threat with relevant vulnerabilities drawn from vulnerability scans, penetration tests, and control assessments.
Assess impact and likelihood
Evaluate each risk in terms of financial, operational, reputational, and regulatory impact. Likelihood should reflect both external threat intelligence and the maturity of your existing controls.
Prioritize and treat
Plot risks on a heat map and prioritize by exposure. Decide whether to accept, mitigate, transfer, or avoid each risk. Define owners, timelines, and investment levels for remediation.
Report and monitor
Translate technical findings into board-ready language. Establish key risk indicators, review cycles, and trigger events so the risk register stays current as the business and threat landscape evolve.
Frameworks
Standards we apply
NIST Cybersecurity Framework (CSF 2.0)
A flexible, outcome-focused structure for organizing risk assessment around Identify, Protect, Detect, Respond, and Recover.
ISO/IEC 27005
A formal risk-management methodology well suited for organizations that need to align with ISO 27001 certification.
NIST SP 800-30
A detailed risk-assessment process for technical systems, including quantitative and qualitative likelihood and impact scales.
OCTAVE
A workshop-based approach that emphasizes organizational risk and stakeholder-driven prioritization.
Risk register
What a risk register entry should include
- Risk statement — a clear, business-oriented description of the risk
- Asset(s) affected — systems, data, facilities, or third parties
- Threat and vulnerability — the pairing that creates exposure
- Impact — financial, operational, reputational, regulatory
- Likelihood — based on threat intelligence and control maturity
- Risk score / heat-map position — a consistent prioritization method
- Treatment — accept, mitigate, transfer, or avoid
- Owner and target date — accountability and timeline
- Residual risk — the expected risk after treatment is applied
