ISO/IEC 27005 – information security risk management

Establish systematic information security risk management that underpins ISO 27001 and regulation.

ISO/IEC 27005 is the international standard providing guidance for information security risk management. It offers a methodical framework for systematically identifying, evaluating and treating risks – and it supports an ISO/IEC 27001 ISMS as well as regulatory requirements (nZKB/NIS2, CRA).

We help you implement this process in practice: we set the context and criteria, build the asset and threat catalogue, rate the risks and prepare a treatment plan you can use directly for the Statement of Applicability (SoA) and for demonstrating compliance.

What you get

Context and risk criteria

Defining the scope, risk acceptance criteria and assessment methodology per ISO/IEC 27005.

Risk identification and analysis

An inventory of assets, threats and vulnerabilities, impact and likelihood assessment and risk rating.

Risk treatment plan

Selecting controls, accepting residual risk and linking to Annex A controls (ISO/IEC 27002) and the SoA.

Monitoring and review

Setting up ongoing monitoring, review and updating of risks over time.

How it works

  1. 01

    Context and methodology

    We define the scope, criteria and risk management methodology tailored to your organisation.

  2. 02

    Risk assessment

    We identify and rate the risks and propose a treatment plan.

  3. 03

    Rollout and monitoring

    We help implement the controls and set up regular risk review.

Outcomes for you

  • A systematic, repeatable risk management process
  • A basis for ISO 27001 (risk assessment and SoA)
  • Demonstrable risk management for nZKB/NIS2 and the CRA
  • Controls prioritised by actual risk

Frequently asked questions

How does ISO 27005 relate to ISO 27001?
ISO/IEC 27001 requires information security risk management but does not prescribe a specific method. ISO/IEC 27005 provides the guidance on how to do it. Its outputs feed directly into the risk assessment and the Statement of Applicability (SoA) in the ISMS.
Is ISO 27005 certifiable?
No. ISO/IEC 27005 is guidance, not a certification standard – it is the ISMS that is certified to ISO/IEC 27001. ISO 27005 helps you meet its risk management requirements.
Can we use the risk management for the CRA and nZKB too?
Yes. Both the CRA (product risk assessment) and nZKB/NIS2 (organisational risk management) rest on risk assessment. A shared methodological basis per ISO 27005 saves you doing the work twice.
