The Office of Cybersecurity, Energy Security, and Emergency Response (CESER) addresses the emerging threats of tomorrow while protecting the reliable flow of energy to Americans today by improving energy infrastructure security and supporting the Department of Energy’s (DOE) national security mission. CESER’s focus is preparedness and response activities to natural and man-made threats, ensuring a stronger, more prosperous, and secure future for the Nation. 

CESER is tactically and strategically addressing the increased frequency and sophistication of cyber threats. CESER is furthering the Department’s long history of investing in research and development (R&D) by industry and the National Labs of the next generation of advanced technologies. CESER leverages the National Labs to test components and configurations based on feedback from industry. Continuous monitoring tools and capabilities for information systems and control networks and identifying best practices are also vital and supported by efforts such as CESER’s Cybersecurity Risk Information Sharing Program.  

Being prepared and ready to respond quickly and effectively to all hazards is crucial. In partnership with companies across the energy sector through organizations such as the Electricity Subsector Coordinating Council and the Oil and Natural Gas Subsector Coordinating Council, CESER plays a vital role in coordinating Federal and state government strategies with industry. Furthermore, CESER along with energy sector partners, prepare for various types of emergencies through exercises such as Clear Path and GridEx. These exercises help DOE, industry, and government partners test and improve plans, as well as provide insights for future R&D needs.  When an incident occurs, CESER facilitates coordination across the government and with the energy sector to enhance response and recovery efforts while coordinating Federal capabilities to mitigate the impact of energy disruptions.
