Hacking of computer networks and theft of personal data has increased dramatically in recent years. In 2014 alone, over 1 billion personal records were illegally accessed, a 54% increase from the previous year. Several major hacks in recent years have compromised personal information for hundreds of millions of people. As hacking becomes more common, simply deleting files is not enough to protect data, as skilled hackers can recover deleted information. Data Killers is a company that provides certified hard drive destruction services to permanently delete any residual data left on outdated IT equipment, helping protect customer and employee information that could potentially be leaked. Their services are approved by the National Security Agency and provide certificates of destruction for handled drives.
