Christopher Cox Krebs (born January 30, 1977) is an American attorney and cybersecurity expert who served as the first Director of the Cybersecurity and Infrastructure Security Agency (CISA) within the U.S. Department of Homeland Security, appointed in November 2018. He earned a Bachelor of Arts in Foreign Affairs from the University of Virginia and a Juris Doctor from George Mason University School of Law, bringing a legal and policy background to government roles prior to CISA, including positions at the Department of Homeland Security and as a cybersecurity policy director. As CISA director, Krebs led efforts to protect critical infrastructure from cyber threats and played a key role in securing the 2020 U.S. presidential election against foreign interference. He gained national prominence for CISA's statements affirming the security and integrity of the 2020 election, which directly contradicted unsubstantiated claims of widespread election fraud promoted by then-President Donald Trump, leading to Krebs' firing on November 17, 2020, via Twitter. Following his ouster, Krebs has continued to advocate for election security and cybersecurity, co-founding the Krebs Stamos Group, a consulting firm focused on risk management and advisory services. He has testified before Congress, written op-eds, and spoken publicly on threats to democracy and infrastructure, positioning himself as a leading voice in national security discussions. Krebs is recognized for his nonpartisan approach to cybersecurity challenges, and no major legal controversies or personal scandals are associated with him.
