Achieving ISO 27001 certification is more than just checking compliance boxes—it’s about building a resilient information security management system (ISMS). A cornerstone of this process is the risk assessment and treatment plan. This guide explains how an ISO 27001 consultant helps organisations identify, evaluate, and treat information security risks to meet ISO 27001:2022 requirements.
📌 What is an ISO 27001 Risk Assessment?
An ISO 27001 risk assessment is a systematic process used to identify and evaluate potential threats and vulnerabilities that could impact your organisation’s information assets. It determines the likelihood and impact of such risks and provides a basis for deciding how to manage them.
Key Objectives:
- Identify information security risks
- Evaluate likelihood and impact
- Prioritise actions based on risk appetite
- Document results to satisfy ISO 27001 auditors
🧠 The Role of an ISO 27001 Consultant in Risk Assessment
An experienced ISO 27001 consultant brings clarity, structure, and precision to the risk assessment process. They ensure that the assessment aligns with Annex A controls and ISO 27005 guidance while tailoring the approach to your business context.
A consultant will:
- Define the scope and methodology
- Identify your organisation’s information assets
- Analyse threats, vulnerabilities, and impacts
- Calculate risk levels using qualitative or quantitative methods
- Facilitate workshops and interviews with key stakeholders
- Document findings for audit readiness
Their role is not just advisory—they help embed risk-based thinking throughout your ISMS.
🧼 ISO 27001 Risk Assessment Process: Step-by-Step
Here’s how an ISO 27001 consultant typically conducts a risk assessment:
1. Define Risk Criteria
Establish how risks will be evaluated—this includes setting impact levels, likelihood scales, and risk acceptance thresholds.
2. Identify Risks
List your information assets (e.g. data, systems, services) and determine potential threats (e.g. cyberattacks, human error) and vulnerabilities (e.g. outdated software, weak access controls).
3. Assess Risks
Evaluate the likelihood and impact of each risk scenario. Most organisations use a risk matrix (e.g., Low/Medium/High).
4. Prioritise Risks
Based on their severity, risks are prioritised for treatment or acceptance.
5. Document Results
All risk scenarios and evaluations must be recorded in a risk assessment report, essential for audit evidence.
🛡️ What is a Risk Treatment Plan in ISO 27001?
After risks have been identified and assessed, the next step is to treat them. An ISO 27001 risk treatment plan outlines how each risk will be managed—whether by mitigating, transferring, avoiding, or accepting it.
Key Elements:
- Selected risk treatment options
- Justification for control selections
- Responsible personnel
- Deadlines and review dates
- Link to Annex A controls (from ISO/IEC 27001:2022)
🔧 How ISO 27001 Consultants Create an Effective Risk Treatment Plan
A consultant plays a vital role in ensuring your risk treatment plan is both compliant and practical. Here’s how they help:
- Map risks to ISO 27001 controls in Annex A
- Balance security and business needs—not all risks need full mitigation
- Customise controls—no one-size-fits-all approach
- Facilitate stakeholder approval and buy-in
- Support implementation tracking with risk registers and action plans
📋 Real-World Example
Scenario:
A software company identifies a high-risk vulnerability in remote access procedures. The potential impact is severe due to sensitive customer data.
Consultant’s Role:
- Recommend implementing multi-factor authentication (Annex A.5.17)
- Assign IT team for implementation within 30 days
- Monitor and review for effectiveness
- Update treatment plan and risk register
This structured approach ensures risk is reduced to an acceptable level—meeting ISO 27001 requirements and improving overall security posture.
✅ Why Work with an ISO 27001 Consultant?
