C2M2 Model Update – Invitation to Participate

The C2M2 has become one of the most important tools for assessing the cybersecurity posture of organizations in the energy sector. During 2020, the C2M2 Program has been working with the energy sector to update and validate the C2M2 model, ensuring that it reflects an evolving threat landscape and the emerging security needs of energy companies. As part of this effort, the C2M2 Program has formed a C2M2 Working Group of industry partners comprising representatives of electricity, oil and gas companies, trade associations, and other cybersecurity experts—to inform technical reviews of the model and pilot the Version 2.0 draft before it is published.


The Electricity Subsector Cybersecurity Capability Maturity Model

The Electricity Subsector Cybersecurity Capability Maturity Model (ES-C2M2) was established as a result of the Administration’s efforts to improve electricity subsector cybersecurity capabilities, and to understand the cybersecurity posture of the energy sector. The ES-C2M2 includes the core C2M2 as well as additional reference material and implementation guidance specifically tailored for the electricity subsector. The ES-C2M2 comprises a maturity model, an evaluation tool, and DOE facilitated self-evaluations.

The ES-C2M2 provides a mechanism that helps organizations evaluate, prioritize, and improve cybersecurity capabilities. The model is a common set of industry-vetted cybersecurity practices, grouped into ten domains and arranged according to maturity level. The ES-C2M2 evaluation tool allows organizations to evaluate their cybersecurity practices against ES-C2M2 cybersecurity practices. Based on this comparison, a score is assigned for each domain. Scores can then be compared with a desired score, as determined by the organization’s risk tolerance for each domain.

Facilitated self-evaluations provide organizations with an opportunity to conduct ES-C2M2 evaluations with the aid of experienced facilitators in a one-day structured walk-through. Facilitators guide discussions, answer questions, and clarify model concepts to increase the accuracy of an evaluation.

The model is publicly available and can be used by any organization to enhance its cybersecurity capabilities. More information is available in the FAQs. For organizations performing self-assessments, a C2M2 Facilitators Guide and C2M2 toolkit are available.

The Energy Department continues to work with public and private partners to support adoption of the C2M2. If your organization has questions about the C2M2 model or toolkit, please contact the C2M2 team at
