EBIOS Risk Manager: the risk analysis method
EBIOS Risk Manager is the method for risk analysis and managing digital risks promoted by ANSSI. It helps identify the threat scenarios that are genuinely concerning for an organization and prioritize security efforts where they matter.
Why EBIOS Risk Manager?
Many organizations secure their systems "by feel," without a clear view of what truly threatens them. EBIOS Risk Manager (EBIOS RM) provides a structured approach to connect threats, essential assets, and stakeholders, and build credible risk scenarios.
Its main value: combining a compliance-based approach (a security baseline) with a scenario-based approach (who would want to attack us, how, and with what impact?). It directly feeds into an SMSI ISO 27001 and regulatory initiatives such as NIS2. BCIT offers dedicated support: EBIOS Risk Manager.
The 5 EBIOS RM workshops
1. Scoping & security baseline
Define the scope, essential assets, and expected security baseline (frameworks, gaps).
2. Risk sources
Identify who could cause harm (risk sources) and their intended objectives.
3. Strategic scenarios
Map stakeholders and high-level attack paths to essential assets.
4. Operational scenarios
Technically detail attackers' operating methods through to supporting assets.
5. Risk treatment
Decide on measures, the accepted residual risk, and the continuous improvement plan.
An iterative approach
The analysis is reassessed over time, in line with changes in the threat landscape and the information system.
Who is it for?
EBIOS RM is suitable both for a global analysis of the information system and for assessing a specific project (new application, cloud migration, etc.). It is particularly relevant for organizations subject to regulatory requirements, or those that want to make their security priorities objective rather than follow a list of "standard" measures. It structures the thinking upstream of a penetration test or an audit.
Linking risk to decision-making
The strength of EBIOS RM is transforming a technical topic into decision support for management: which scenarios are unacceptable, what level of risk is accepted, and where to invest first. When conducted properly, the analysis avoids two pitfalls: over-investing in minor risks and leaving major threats as blind spots. It fits into a logic of governance, risk & compliance.
Conducting an EBIOS RM analysis, step by step
Scope the perimeter
Define what is being analyzed, the essential assets, and the reference security baseline.
Identify threats
Determine the relevant risk sources and their objectives.
Build the scenarios
Develop strategic and then operational scenarios, from high-level to technical.
Assess & prioritize
Rate likelihood and severity to rank the risks to be treated.
Decide on treatment
Choose the measures, formalize the accepted residual risk and the action plan.
Reassess regularly
Update the analysis as the SI and the threat landscape evolve.
Why work with BCIT?
A well-controlled method
We facilitate EBIOS RM workshops directly with your technical teams and management, not only through theoretical training: the method remains usable by your staff once our engagement is complete.
Decision-oriented
Credible scenarios and clear priorities, rather than a catalogue of generic measures.
Linked to your compliance
Discover our offer EBIOS Risk Manager, the foundation of an SMSI and NIS2.
Finally know what really threatens you 🚀
Let's take 15 minutes to scope an EBIOS RM risk analysis tailored to your context and challenges.
