In a context where digital threats continue to grow, organizations must adopt solid approaches to identify, assess, and mitigate cybersecurity risks. The EBIOS Risk Manager (EBIOS RM) method, revised in 2024, stands out as an essential solution. Adopted at the european level, this structured method provides a rigorous framework for integrating digital risk management into an organization's overall strategy. This article explores this standard in detail, including its objectives, principles, and practical application.
EBIOS RM (Expression of Needs and Identification of Security Objectives – Risk Management) is a registered trademark of the General Secretariat for Defense and National Security (SGDSN). It is a methodology published by the National Cybersecurity Agency of France (ANSSI) to assess and manage cybersecurity risks. With the 2024 version, EBIOS RM takes a new step by integrating international standards requirements, particularly ISO/IEC 27001:2022, and aligning with European risk management practices. Often compared to ISO 27005, this methodology stands out for its pragmatic and scenario-based approach.
EBIOS RM provides a structured framework to identify threats, assess their impacts, and define appropriate security measures. It relies on a detailed analysis of risk scenarios, emphasizing:
The main objective of EBIOS RM 2024 is to help organizations strengthen their cybersecurity risk management while optimizing resources and ensuring compliance with current regulations. More specifically, the methodology enables organizations to:
One of the core principles of EBIOS RM is to proactively identify threats, vulnerabilities, and risk scenarios before they materialize. Through a proactive approach, this methodology provides a clear vision of each organization’s risk ecosystem, facilitating optimal preparation against cyber threats.
Adopting EBIOS RM helps companies efficiently allocate resources based on the most critical business challenges. This ensures targeted protection of essential assets while minimizing costs and efforts related to less relevant security actions.
Successful risk management requires ensuring that cybersecurity is fully aligned with the organization’s strategic and operational priorities. EBIOS RM ensures that security measures contribute to achieving the company’s overall objectives while protecting its long-term interests.
EBIOS RM facilitates the integration of cybersecurity with existing standards and regulations such as GDPR, the NIS2 Directive, and ISO/IEC 27001 standards. This approach enables organizations to meet regulatory requirements smoothly while strengthening their security posture.
Since the latest updates to the EBIOS RM Framework, it is now fully compatible with ISO27005:2022 - Guidelines for Information Security Risk Management. The EBIOS club provides the following infographic illustrating the correspondence between the five EBIOS RM workshops and ISO27005.
The EBIOS Risk Manager (EBIOS RM) methodology is based on five complementary workshops that allow organizations to identify, assess, and address cybersecurity risks. These workshops provide a progressive and consistent approach to understanding exposure to threats and implementing appropriate protective measures.

This workshop defines the scope of the analysis by identifying the critical assets to be protected, such as sensitive data, critical infrastructures, and vital services. It also sets security objectives and aligns stakeholders on a common vision of the challenges. The outcome of this workshop is a validated security perimeter that is consistent with the organization's strategy.
The goal here is to identify actors that could pose a threat to the defined perimeter. Risk sources are categorized as internal (human errors, insider threats) and external (cybercriminals, nation-states, hacktivists, etc.). This workshop relies on modeling the interactions between assets and their environment to anticipate potential threats.
Based on the identified risk sources, this workshop aims to develop plausible attack scenarios by combining vulnerabilities with realistic attack methods. The objective is to assess threats from a strategic perspective, considering attacker motivations and potential impacts on the organization. These scenarios help determine the main directions for risk management.
This workshop translates strategic scenarios into concrete situations that could affect critical assets and business processes. It involves assessing the probability and impact of each risk to prioritize them. This prioritization allows organizations to focus efforts on the most significant threats and define appropriate risk tolerance levels.
The final step of the methodology, this workshop consists of defining and implementing security measures proportionate to the identified risks. These measures can be technical (encryption, network segmentation), organizational (incident response protocols), or contractual (cybersecurity clauses in supplier agreements). The objective is to ensure an optimal level of protection while maintaining the organization’s resilience.
Through these five workshops, EBIOS RM enables robust risk management aligned with the strategic and operational challenges of organizations. This methodical approach helps anticipate threats, structure defense mechanisms, and strengthen cybersecurity posture.
EBIOS Risk Manager (EBIOS RM) is much more than just a risk analysis method. It is a robust methodological framework, designed to help organizations understand, anticipate, and address threats to their information systems. By adopting this approach, companies can structure their risk management in a coherent manner, while optimizing resources and facilitating decision-making at the highest levels.

One of the main strengths of EBIOS RM is its ability to align cybersecurity with the organization's strategic objectives. By focusing on the most critical risk scenarios, it allows decision-makers to concentrate their efforts on risks that significantly impact business continuity, protection of sensitive data, and resilience to cyberattacks.
EBIOS RM promotes a collaborative approach involving the various stakeholders within the organization. Its structured framework allows both technical experts and decision-makers to be effectively involved, ensuring a better understanding of risks and more efficient management. Risk modeling is carried out in a clear and accessible way, making it easier to adopt relevant and appropriate protective measures.
As the cybersecurity landscape is constantly evolving, EBIOS RM incorporates a continuous improvement process. Risk analyses are not fixed over time, but regularly updated based on the evolution of threats, vulnerabilities, and new cybersecurity challenges. This flexibility ensures optimal and dynamic protection against emerging risks.
