A lawful basis under GDPR allowing data processing when necessary and balanced against individuals’ rights.
DESCRIPTION
Legitimate Interest is one of the GDPR lawful bases for processing personal data without consent. It requires a three-part test: purpose, necessity, and balancing of interests versus risks to individuals. Organizations must document the assessment and provide transparency via privacy notices. It is suited to reasonable business purposes like fraud prevention, network security, or direct marketing where rights are respected. Misuse can erode trust and invite regulatory action; careful governance is essential.
