How This Briefing Works
This dossier opens with key findings, then maps the gap between what Mediamath discloses and what BLACKOUT observed at runtime. From there: what it means for your organization, what to do about it, and the detection evidence underneath. BLACKOUT observes runtime browser behavior and cites the regulations that address each pattern — legal determinations are your counsel's call.

vendor fires before consent
Briefing
MediaMath operates a demand-side platform that activates tracking pixels before consent collection. Third-party cookie syncing enables persistent cross-site identification for ad targeting. Bid stream data sharing exposes visitor behavior to hundreds of advertising participants.
What This Means For You
Removing MediaMath disrupts programmatic advertising campaigns and retargeting flows. Marketing loses granular attribution for display ad conversions. However, retention creates risk: GDPR complaints for unlawful processing, ePrivacy enforcement for non-compliant cookie use, revenue loss if major browsers block third-party cookies used by MediaMath.
Risk Channel Breakdown
Distorts attribution data
Feeds competitor intelligence
Expands attack surface
Consent bypass through immediate pixel firing violates GDPR Article 6 lawfulness requirements and ePrivacy Directive cookie rules.
