As the key U.S. Department of Energy (DOE) resource for Cybersecurity, Energy Security, and Emergency Response, CESER consults and coordinates with subject matter experts in many areas across the Energy Sector. CESER coordinates with DOE’s Office of International Affairs (IA) to review and provide input, analysis, and recommendations into . Engagement requests, briefing papers, and internationally focused agreements that include CESER equities. CESER also works closely with the DOE- IA to develop action plans for specific, and sometimes joint, projects. When engaged in internationally focused projects that contain CESER equities and areas of expertise, CESER also may provide subject matter expertise, funding, and program management.

Through these projects and while engaging with international partners, CESER leverages appropriate opportunities to share lessons learned and tools developed, such as the Cybersecurity Capability Maturity Model (C2M2). 

CESER also engages with Canada and Mexico through their representatives at meetings of the Energy Government Coordinating Council, Electricity Subsector Coordinating Council, and Oil and Natural Gas Subsector Coordinating Council.
