ADP

ADP Dealer Services operates as a software‑as‑a‑service provider focused on the automotive dealership sector. Its core offerings include customer relationship management, inventory tracking, sales processing, and financing tools delivered through a cloud platform. The company is headquartered in the United States of America. It serves dealerships across North America, providing technology that supports day‑to‑day operations in showrooms and back offices. In addition to its dealership‑focused suite, ADP also offers payroll and tax‑related services, as evidenced by its customer portal used for W‑2 and salary data access. The organization is commonly referred to by the aliases ADP and ADP Dealer Services.

More than 15,000 North American dealerships rely on ADP Dealer Services’ platform for their operational needs. A 2024 cyberattack against the provider caused widespread system shutdowns, prompting the temporary suspension of services and forcing affected dealerships to adopt manual workarounds such as paper‑based processes. While partial restoration of phone and core systems occurred, other applications remained offline during testing, and the company’s official statements emphasized ongoing recovery without confirming the specific nature of the attack. A separate incident in 2016 involved fraudsters exploiting static authentication mechanisms on ADP’s customer portal to access tax and salary data, leading to unauthorized W‑2 form retrieval for fraudulent tax refund filings. In response, ADP implemented web monitoring to detect exposed customer registration codes, disabled self‑service registration, and explored supplemental authentication measures such as knowledge‑based questions. The breach was described as impacting only a small subset of clients, with the company noting that the compromised personal data originated outside its own systems.
