Observation Coverage

BLACKOUT observes runtime behavior in the browser. This dossier reflects browser-side execution, which is one of five vendor data-egress classes. Server-to-server transfers, backend integrations, and offline data flows are outside this observation boundary.

BLACKOUT observes runtime behavior and cites the regulations that address that behavior pattern. Legal determinations are the customer's counsel's call.

How This Briefing Works

This dossier opens with key findings, then maps the gap between what Sonobi 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.

Summary

Briefing

Sonobi provides header bidding and programmatic advertising infrastructure with behavioral targeting. Detected BTI codes indicate session recording (C07), behavioral biometrics (C06), consent bypass (C09), fingerprinting (C10), and defeat device behavior (C01). Perfect legal tail risk score reflects ad tech architecture that initiates tracking before consent collection.

Customer Impact

What This Means For You

Header bidding exposes your audience to entire programmatic ecosystem before consent. Competitors using same DSPs can target your visitors across the web. Meanwhile, privacy controls block 40%+ of behavioral targeting, systematically reducing CPMs for remaining inventory. Perfect legal tail risk means every pre-consent impression creates regulatory liability.

Risk Channel Breakdown

Programmatic bidding relies on behavioral profiles that are increasingly blocked by privacy controls. If 40%+ of users cannot be targeted behaviorally, CPMs collapse and revenue attribution becomes systematically biased toward trackable users.

Header bidding exposes your visitor inventory to dozens of demand-side platforms. Behavioral profiles are shared across programmatic ecosystem for auction optimization, training competitor targeting models.

Ad serving before consent collection violates GDPR Article 6 and ePrivacy Directive. Every pre-consent impression creates independent violation. Perfect legal tail risk reflects ad tech architecture fundamentally incompatible with consent requirements.
