  • Enforce data quality at scale — identify duplicates in real time and govern how they're handled based on business rules and end-user experience.
  • Prevent duplicates across standard and custom objects, including Lead-to-Contact and Lead-to-Account matching, wherever your org is most exposed.
  • Detect duplicates the instant records are created or updated, before bad data ever reaches downstream systems.
  • Apply the right action at the right moment — block, auto-merge, auto-convert, redirect to an existing record, or report — with full control over enforcement.
  • Extend and customize detection logic with Apex code to fit complex business rules.
  • Govern exactly which records and users each DupeBlocker scenario affects and define precisely which existing and incoming records a scenario compares.

What DupeBlocker: enterprise duplicate prevention does
