A Data Breach Sensitive Source refers to any origin where confidential or personal information is stored, processed, or transferred and becomes exposed due to unauthorized access or poor security measures. These sources are critical points that attackers often exploit to steal sensitive data such as financial records, login credentials, or customer details. Identifying and securing these sources is essential to prevent severe business and legal consequences.

Common sensitive sources include:

• Cloud storage and databases: Often misconfigured or weakly protected.
• Employee devices: Laptops or phones with unencrypted or unsupervised data.
• Third-party applications: Tools with shared access that can leak or misuse information.
• Email servers: A frequent source of phishing and credential theft.

A single breach in any of these areas can cause major reputational and financial harm.
