The recently reported Equifax breach, which exposed the personal information of more than 146 million Americans, is the latest reminder to businesses that they must take steps to ensure the security of their customers’ private information.

The breach also highlights the importance of cyber insurance, which can help cover the costs of responding to such a breach and compensate those who were injured by it.

recent story in the New York Times, however, illustrates the importance of reading the fine print of a cyber policy closely before procuring coverage. According to the Times, the company’s former CEO, Richard F. Smith, told the House Energy and Commerce Committee that the breach happened “because of a mistake by a single employee.”

On multiple occasions, Mr. Smith referred to an ‘individual’ in Equifax’s technology department who had failed to heed security warnings and did not ensure the implementation of software fixes that would have prevented the breach.
