AtData operates in the information services sector and is based in Dedham, Massachusetts. It specializes in email identity intelligence to help organizations detect fraud at its earliest signal—the email address. The company draws on more than 25 years of observed behavior and processes over 150 billion deterministic activity signals each month to verify and assess email-anchored identities in real time, exposing risk before fraud escalates. By constructing a complete identity view that includes email, name, phone, address, IP, and historical behavior, AtData enables clients to block synthetic identities, fake accounts, transactional fraud, and account takeovers with minimal friction.

The customer base comprises enterprises seeking stronger digital trust and cleaner data, placing AtData among information services providers that focus on email address intelligence and fraud prevention. In February 2026, Experian plc announced its acquisition of AtData, signaling a shift in ownership and potential integration within Experian's broader data and intelligence ecosystem.
