MARS-E for DPOs
What does MARS-E require of a DPO?
Data Protection Officers oversee privacy compliance, manage data subject rights requests, conduct privacy impact assessments, and serve as the point of contact with data protection authorities. Under MARS-E, which defines 8 controls, the work that lands on a DPO is deciding which controls you own outright, which you share, and which belong to another team, then holding evidence for the first group.
Which MARS-E controls land on the DPO
Data Protection Officers oversee privacy compliance, manage data subject rights requests, conduct privacy impact assessments, and serve as the point of contact with data protection authorities. The role is mandatory under GDPR for many organisations.
MARS-E defines 8 controls across 8 domains that directly affect the DPO role. Understanding which controls fall within your ownership, which are shared, and which are owned by other teams is the foundation of effective compliance management.
