Payroll services company Automatic Data Processing Inc. on Wednesday disclosed a data breach that apparently affects one of its employer clients.

ADP's security team discovered the intrusion during routine monitoring of its systems. The breach involved a client of Workscape, a benefits administration provider that ADP recently acquired. ADP did not identify the client, which was notified of the breach.

ADP said the breach did not involve payroll data, and the information that was at risk was part of a product ADP's benefits administration business no longer sells.

ADP said it isn't releasing details of the breach because it's subject to an ongoing law enforcement investigation. The Roseland, N.J., company is working with authorities to determine what caused the breach. Based on initial findings, ADP said it "believes that the impact of the incident is limited to a single client."

Workscape was an 11-year-old privately held company based in Marlborough, Mass., when ADP acquired it last August. Workscape then had 400 employees, according to a news release, and served "numerous" large companies, with 3.5 million users in more than 180 countries.
