Backhauling data refers to the practice of moving data from a cloud repository where it resides to an external location for analysis and classification. Backhauling data introduces risk because it requires opening an entry point to allow the analysis service to access repositories. Backhauling also introduces challenges in tracking and controlling data, which can make compliance with regulations such as GDPR and CCPA more complex and expensive. Finally, it expands the attack surface by introducing third party risk, meaning that organizations need to spend time and effort to understand and audit the security controls and policies of their data classification solutions.
