Founded in 2000, the Center for Internet Security is a nonprofit group specializing in cyber-security research which provides cyber-security consulting services to local, state, and federal governments. The organization has been awarded $115 million in federal grants by the Department of Homeland Security and Department of Defense since 2010, and has received $3.6 million in cybersecurity contracts from numerous federal agencies since 2005. 
The Center for Internet Security is led by president and CEO John Gilligan, who previously served in senior advisory positions in intelligence and security for the United States Airforce, Department of Energy, and White House Cyber Security Commission under the Obama administration. 
Since 2016, the organization has been active in researching and providing cyber security for election administration. In April 2019, the organization published “A Guide for Ensuring Security in Election Technology Procurements,” which was funded by a $290,000 grant from Pierre Omidyar’s Democracy Fund.
