Only 6% of all breaches in 2019 were suffered by financial services firms, according to Bitglass. However, these breaches compromised significantly more records than those that occurred in other industries. In total, more than 60% of all leaked records in 2019 were exposed by financial services organizations. This is at least partially due to the Capital One mega breach, which compromised more than 100 million records.
