Email is the most common technology used in accidental data breaches, according to a survey of 1,000-plus U.S. companies sponsored by data security platform Egress and conducted by Opinion Matters research group.

Eighty-three percent of organizations surveyed said they experienced an accidental data breach. When an employee has unintentionally exposed sensitive data, 51 percent of respondents said it was through an external email provider, such as Gmail and Yahoo. Meanwhile, 46 percent said corporate email was used in an accidental data breach.
