What is Data Leakage?
Every company has sensitive data that must be protected. It can consist of personal health information, intellectual property, customer payment information and order histories, or even trade secrets. Data leakage occurs when this sensitive data is disclosed to unauthorized parties either through malicious intent or an unintentional mistake. Data leakage prevention is a strategy for making sure that this doesn’t occur and that a company’s critical data stays within the corporate network.
While most companies are aware of the importance of protecting the sensitive data listed above, many are unaware of the risks posed by third-party marketing technology. These third-party vendors can leak sensitive customer marketing data to fourth, fifth, and even sixth parties, known as “piggyback tags.” This is particularly perilous because the company does not have a direct relationship with these trespassing technologies. In fact, Ghostery studies have found that of all the vendors on a website, 20-40% have added the code directly, the rest of the vendors are there indirectly.
