Target and Home Depot’s 2013 data breaches have come with a hefty price tag. According to recent filings with the Securities and Exchange Commission, in 2014 Target incurred gross expenses of $252 million related to a hacking incident that compromised the financial and personal data of approximately 110 million customers. Home Depot, whose data breach affected 56 million customers’ credit and debit card information, spent $33 million. The companies are also both facing ongoing lawsuits related to the breaches and Home Depot was subject to a Congressional inquiry into its data security measures. The companies’ disclosures underscore the importance of ensuring that your cybersecurity policies and procedures are fully developed and tested.
