Privacy fines
67.8This check counts only when a source covers the company. With no events it holds the pillar, which is not proof of a clean record. Each recorded event takes points off the pillar, and serious or recent ones count most. Allegation checks, regulator actions and open investigations use half the severity load. EU privacy (GDPR) fines and Irish regulator decisions, last 5 years.
