About the CISA Logo “The blue outer ring and the inner red ring indicate CISA’s unity with DHS and a nod to our efforts to cut through government red tape, while the three blue lines in the outer ring represent the Agency’s three congressionally mandated missions: cybersecurity, infrastructure security, and emergency communications. The eagle faces to the right, signifying CISA’s keen eye on the future and forward posture. The center shield represents CISA’s commitment to “Defend Today, Secure Tomorrow,” while the eagle’s folded wings reinforce CISA’s protection and defense of our nation. The image includes wavelengths representing the emergency communications mission, which emanate from buildings that signify the infrastructure security mission, while the nodes in the eagle’s arm indicate the cybersecurity mission. The bridge represents the vital, two-way connection, communication, and collaboration between the public and private sectors, which is so key to CISA’s mission success.” We connect our stakeholders in industry and government to each other and to resources, analyses, and tools to help them build their own security and resilience.
