How This Briefing Works
This dossier opens with key findings, then maps the gap between what Gumgum 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.

Briefing
Visual advertising platform that captures behavioral patterns, syncs identities across domains, and deploys via tag manager for persistence - all before consent. Combines four high-risk techniques into single surveillance stack. Primary risk: compounded GDPR violations create exponential penalty exposure.
What This Means For You
Marketing teams gain visual ad optimization but inherit exponential consent liability: per-visitor × per-sync-partner × special category biometrics. Engineering teams lose control over tracking due to tag manager deployment. Legal teams face simultaneous violations across four GDPR/ePrivacy provisions.
Risk Channel Breakdown
Limited measurement distortion - primarily ad delivery. Cookie syncing may affect attribution but not core analytics.
Behavioral biometrics + cross-domain syncing enable comprehensive audience profiling. Visual attention patterns combined with cross-site behavior feed competitor targeting intelligence.
Expands attack surface
Four-layer consent violation: (1) loads before consent banner, (2) captures behavioral biometrics without explicit consent, (3) syncs identities with ad network partners, (4) deploys via tag manager for evasion resistance. Creates compounded GDPR liability.
