DLP tools are primarily designed to monitor, detect, and prevent the unauthorized transmission of sensitive or confidential data outside of an organization. This includes preventing data leaks through various channels such as email, file transfers, or cloud services. DLP tools enforce policies to ensure that confidential data does not leave the organization or fall into the wrong hands.
While DLP tools may also analyze data at rest and assist with data classification, their primary function is to block or prevent the loss or unauthorized transfer of sensitive data.

The primary focus of the internal audit quality assurance (QA) team is to ensure that all audit deliverables, whether performed internally or outsourced, meet established quality standards.
This includes evaluating the effectiveness of audit processes, adherence to professional standards, and continuous improvement of audit practices.

The fundamental goal of any DLP solution is to accurately discover sensitive data and enforce controls that prevent its unauthorized disclosure. All other features - cost, reporting, and integration - are secondary to ensuring the tool reliably detects and protects confidential information.

The main objective of implementing security controls within an application is to balance effective data protection with cost efficiency. Controls should provide adequate security proportional to the value and sensitivity of the data without incurring unnecessary expense or complexity.
