AppFolio Data Breach Impacts 72,444 Individuals

AppFolio, Inc., a leading provider of cloud-based business software for the real estate industry, experienced a data breach stemming from a security incident involving one of its vendors, Salesloft, a sales enablement software provider. The cybersecurity incident reportedly involved hundreds of companies working with Salesloft.

AppFolio was first alerted of the data breach on Aug. 22, 2025. The incident was traced back to unauthorized access to AppFolio’s customer relationship management (CRM) system through a vulnerability in Salesloft. An unauthorized actor was able to retrieve data from AppFolio’s hosted CRM system, specifically targeting a location that contained personal information between Aug. 8 and Aug. 18, 2025

An investigation took place and on Sept. 18, 2025, determined that the data breach compromised names and Social Security numbers. The AppFolio incident affected a total of 72,444 individuals in the United States.

The cyberattack was disclosed to multiple state authorities beginning on Oct. 6, 2025, including the California, Maine, Massachusetts, Oregon, Texas, Montana, Washington and New Hampshire Attorney Generals' offices. Affected individuals includes 5,056 Texas residents, 2,882 Washington residents, 148 in Maine, 932 Massachusetts residents, 337 in Montana and 231 in New Hampshire.
