Who We Are

Region 8's Headquarters are in Denver, Colorado

Serving just over 11 million people and covering 573,259 square miles of mountains, rivers, high deserts, plains, farmland, urban areas, unique geologic features and one of the largest coal reserves in the world, Region 8 is a complicated and ever-changing part of the country. Natural risks impacting the area are diverse. Drought and wildfire in summer and fall, flash floods following extreme rain and hail events in spring, plus snow and ice storms in winter all pose significant threats to critical infrastructure and the surrounding communities. Adverse human-caused events, such as cyber and physical security attacks, chemical hazards, and shooting and bombing incidents, also have lasting and dramatic effects. Regardless of the nature or cause of an incident, CISA Region 8 staff is ready to help partners build resilience and readiness for mitigating risk and provide training and program exercises to support preventative and proactive planning.

Current Activities

Russia’s invasion of Ukraine could spill over from Eastern Europe by way of malicious cyber activity against the U.S. homeland. Evolving intelligence indicates that the Russian Government is exploring options for potential cyberattacks. Every organization—large and small—must be prepared to respond to disruptive cyber incidents. As the nation’s cyber defense agency, CISA stands ready to help organizations prepare for, respond to, and mitigate the impact of cyberattacks. When cyber incidents are reported quickly, we can use this information to render assistance and as warning to prevent other organizations and entities from falling victim to a similar attack.

Our Shields Up! webpages have the latest information. Regional advisors are available to assist you. Please contact us with any reporting questions at:  

Report a cyber incident here.

CISA is committed to working collaboratively with state and local governments, election officials, federal partners, and vendors to manage risks to national election infrastructure. In March, Regional Director Graff along with CSA Edman and PSA Davis joined election officials from South Dakota to talk election security.   In March, CISA Region 8 and Region 9 Protective Security Advisors toured Glen Canyon Dam with the Bureau of Reclamation and discussed critical infrastructure. CISA is proud to partner with Reclamation in protecting our nation's critical infrastructure like dams and power plants. Happy Women in Cyber Month!
