Region 9

Region 9

CISA serves as the Nation’s risk advisor, focusing on protecting today and securing tomorrow. Through our efforts to understand and advise on cyber and physical risks to the Nation’s critical infrastructure, we help partners strengthen their own capabilities. We connect our stakeholders in industry and government to each other and to resources, analyses, and tools to help them build their own cyber, physical and communications security, and, in turn, strengthen national resilience.  

Led by a Regional Director based in Oakland, California, CISA’s Region 9 staff provides cybersecurity, physical infrastructure security and chemical security services to 150 tribal nations and the following states and territories: 

  • Arizona 
  • California  
  • Hawaii 
  • Nevada 
  • Guam 
  • American Samoa 
  • Commonwealth of the Northern Mariana Islands 

Regional Director David Rosado leads a cadre of security professionals located throughout the region who manage mission execution through steady state and incident response support operations. In addition to supporting the Nation’s coronavirus (COVID-19) response, Region 9 personnel work to carry out CISA’s five priorities:  

  • Improve supply chain security against cyber threats from malicious actors and the rollout of 5G technologies;  
  • Harden federal networks (the civilian .gov domain); 
  • Reduce risk at soft targets;  
  • Enhance election security; and 
  • Protect critical infrastructure that includes industrial control systems and the processes that provide vital services in critical infrastructure.
