ISO 27005 provides guidelines for information security risk management, which is strongly complementary to EBIOS RM. It provides a broader framework that EBIOS RM can fit into.

ISO 27001 is a standard for information security management systems (ISMS). EBIOS RM can be used as a risk assessment methodology to support the implementation of an ISO 27001 compliant ISMS, hence they are complementary.

NIST provides frameworks and guidelines for cybersecurity risk management (e.g., NIST Cybersecurity Framework, NIST Risk Management Framework), which are often used in conjunction with or as an alternative to EBIOS RM. Can be seen as an alternative (competitor) or a framework that EBIOS RM fits in. However, NIST provides comprehensive guidance that is complementary, particularly NIST 800-30.
