Many states are closing all but “essential” businesses to help stop the spread of COVID-19, but they don’t all agree on the definition of “essential.” Companies are asking what qualifies? The Department of Homeland Security’s Cybersecurity & Infrastructure Security Agency (CISA) identified 16 industries, including critical manufacturing, that are deemed crucial to the United States’ coronavirus response. Review the CISA guidance on critical manufacturing here: https://www.cisa.gov/identifying-critical-infrastructure-during-covid-19. Manufacturers can help strengthen this guidance that many states are already adopting by emailing CISA.CAT@cisa.dhs.gov with detailed examples of why manufacturing and the supply chain is critical, life-sustaining infrastructure.
