What we do

VoteShield helps election officials in the United States keep voter data safe from interference, errors, and misinterpretation.

How we do it

Every state makes voter data publicly available. These voter files contain non-sensitive information on all registered voters in a particular state, and are commonly used by political parties and campaigns to facilitate voter outreach. VoteShield uses the data from these public files to track changes to voter records across the country.

We analyze demographics.

We examine statewide trends.

We communicate issues early.

VoteShield Coverage

Available currently to election officials in 27 states.

VoteShield works in collaboration with election officials in states across the country and political spectrum.

An account is required to access the data for each state in order to share our analysis securely, not as a product or service. Accounts are provided free of charge and are only available to election officials in their own state.

How election professionals at the county and state level are using VoteShield.

‘‘VoteShield is an important component to help us ensure the integrity of Iowa’s voter data and elections. The system is available for all 99 county auditors to use. Auditors know their counties best, so if an anomaly is detected, they are able to investigate it themselves.’’

‘‘VoteShield offers an unparalleled external analysis of changes to voter rolls, which ensures that large scale voter registration irregularities are not occurring, and if they were, that we would detect them.’’
