Colorado SOS Michael Coffman completed court mandated testing and recertification of voting systems used in the state and issued some dramatic rulings which were immediately subject to a firestorm of controversy.
Premier (formally known as Diebold) All voting equipment submitted for recertification passed.
Sequoia The optical scan devices, Insight and 400-C, used to count paper ballots both passed, but the electronic voting machines, the Edge II and the Edge II Plus, both failed due to a variety of security risk factors, including that the system is not password protected, has exposed controls potentially giving voters unauthorized access, and lacks an audit trail to detect security violations.
Hart The optical scan devices, eScan and BallotNow, both failed because test results showed that they could not accurately count ballots. The electronic voting machine, eSlate, passed.
ES&S The optical scan devices (M 100 and the M650) both failed because of an inability to determine if the devices work correctly and an inability to complete the testing threshold of 10,000 ballots due to vendor programming errors. The electronic voting machine (iVotronic) failed because it is easily disabled by voters activating the device interface, and the system lacks an audit trail to detect security violations.
