The growing threat of cybercrime has been on the minds of many voters. Recently, there have been many questions about the security of the voter data under the care of the election authorities. Here, at the Sangamon County Clerk’s office, we are committed to cybersecurity, as well as the physical security, of the data in our care.

Our electronic voting equipment consists of the M100 (Optical Scan) tabulator and AutoMARK (Touch Screen). These machines are never connected to the internet. The M100 and AutoMARK machines are tested before and after each election to ensure they are functioning correctly. The electronic voting equipment and memory cards are kept in secure locations when not being used for an election.

During an election, we employ numbered security seals on the M100 machines, to ensure the critical components are not tampered with. The memory card used with the M100 machine has only the ballot style and party (if it is a Primary election). None of the voter’s information is on the memory card. When the election ends, our personnel operates the equipment that tallies the results. They are the only people who handle the data from the memory cards. Additionally, our Voter Registration System and Election Night Software Reporting vendors regularly undergo various cyber reviews, assessments and scans to ensure the systems are safe from vulnerabilities and unknown actors.


The County Clerk’s office and the Sangamon County IS department are working together along with State and Federal entities, such as the Department of Homeland Security, to maintain the integrity of elections and voter information. We have also designated a competent staff member to oversee our cybersecurity. Through continuing education about cybersecurity, we are striving to make certain future elections and voter data remain safe from cyberthreats.
