Therefore, when it is time to retire computers, mobile phones, and other IT equipment, using a data and electronic waste destruction company specifically certified to destroy and dispose of electronic waste properly is the way to go. In addition, these certified companies follow a standardized and secure data destruction protocol, which can prevent data leakage from retired devices. Improper disposal of electronic waste can lead to data leaks, particularly if the devices are sold to buyers without being sanitized. Since the data inside an improperly discarded device has not undergone the correct data destruction process, the data on these devices can potentially be still accessible to bad actors. As a result, data theft may occur, which bad actors can exploit for profit. In worse-case scenarios, this kind of data theft can lead to property and safety damage.
