Privacy is great for business. Virtually every enterprises and organization acquire, use and store personally identifiable information (PII) such as social security number, contact information, account and credit card numbers. It may have it for their employee, and customers and depending on their area of business, may also have it for patients, residents and students depending on their industry. What is PII? According to the U.S. Office of Management and Budget, is any information that can be used to uniquely identify, contact or locate an individual, or can be used with other sources to uniquely identify a person. What is the enterprise level of personally identifiable information protection? Due to the security issue, the enterprises are required to keep your customers as secure and protected as possible. Enterprises are required to manage private PII appropriately and protect it from cyber threats, loss and unauthorized access. When enterprises misuse or lose sensitive data, they will carry a steep financial cost. Fines of losing personal data is very expensive. In 2018, the European Union’s General Data Protection Regulation will introduce fines for groups of enterprises of to 20 million Euro or 4 % of annual worldwide turnover. It represents that handling data protection becomes very important. And also, the consequences extend on reputation damage and customer trust.
