Summary
Norway's Data Protection Authority has fined Microsoft-owned Xandr $9.6 million for unlawfully processing and sharing sensitive data of Grindr users. The ad firm, acting as an intermediary, exposed users' sexual orientation information to thousands of companies without verifying explicit consent between 2018 and 2020. This marks the largest fine ever issued by the authority, highlighting serious breaches of data privacy.
The lesson from this incident
Full lessonXandr, acting as an advertising intermediary, processed and distributed highly sensitive sexual orientation data from Grindr users to thousands of third-party companies without obtaining or verifying explicit user consent — a clear violation of GDPR principles. The root cause lies in a failure to implement proper data governance controls within the advertising supply chain, where sensitive personal data flowed freely without adequate legal basis. This case illustrates how ad-tech ecosystems can become vectors for massive privacy violations, often invisible to the individuals whose data is being exploited. The record fine signals that regulators will hold intermediaries — not just data originators — accountable for unlawful processing, raising the stakes for all participants in digital advertising pipelines.
What helps against this
How we list vendors- Cloud security posture management (CSPM and CNAPP)
Misconfigured cloud storage and over-permissive roles get caught before they leak.
- Data loss prevention (DLP)
Sensitive data cannot quietly leave by email, upload, USB stick or AI tool.
- Compliance automation (GRC)
Evidence for NIS2, DORA and ISO 27001 is collected continuously, not in a rush before the audit.
