What you don’t get with commercial-off-the-shelf (COTS) tabulators:

  • Purpose-built equipment. Election experts designed ES&S tabulators specifically for elections.

  • No scanning interruptions. ES&S tabulators scan and tabulate previously folded and damaged ballots.

  • Customizable sorting. ES&S tabulators allow for user-definable, real-time sorting, including both physical and digital ballot management.

  • Longer product life. ES&S products are engineered with industrial-grade components, ensuring a 5-7 year production and service parts supply. Our parts manufacturers are dedicated to maintaining form, fit and functional equivalents when an inevitable change comes. This allows ES&S to support our products typically 10+ years.

Security you can count on.®

Physical and system access controls
  • The central count tabulators (DS450, DS850 and DS950) use keylocks and security seals to protect against tampering or intervention in system operations.
  • All data ports and the power switch are secured behind clear plastic lockable and sealable doors to protect access and allow election officials to easily detect unauthorized access.
System application controls
  • These tabulators cannot write or otherwise change the election program once installed. The central count election media content is digitally signed and verifiable using the application.
  • No options to change any ballot information exist on the central count tabulators.
  • All administrative functions are limited to the controls allowed through the touch-screen interface for machine operation only.
Encryption, hash validation and digital signatures
  • The units use digital encryption and signing of key configuration and data files for complete integrity of the election and results. All central count data is signed with FIPS-compliant digital signature algorithms. All generated data is also signed so that the program receiving the data can validate it.
Audit logs
  • The tabulators provide options for printed and electronic real-time logs of all activity performed, allowing users to reprint logs on-demand or export electronic logs for review.
  • The tabulators log all passcode attempts, whether successful or failed, to the digitally signed audit log. In addition, all user actions (such as administrative selections and open and close poll events), whether successful or failed, are written to the audit log.
  • Only the system can create, read, modify and delete the audit log content because the user interface is locked out of these functionalities.
