How This Briefing Works
This dossier opens with key findings, then maps the gap between what Theirstack 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
Theirstack enriches visitor data with company intelligence, capturing behavioral signals for B2B prospecting. BTI codes (C01 defeat device, C06 biometrics, C07 session replay, C09 consent bypass, C10 fingerprinting) indicate sophisticated tracking. Data enrichment category confirms visitor behavioral data flows to databases where competitor sales teams access enriched profiles.
What This Means For You
Marketing spend trains competitor prospecting databases. Visitor behavioral data enriches competitor intelligence on which companies visit your site, what content they engage with, and when buying intent appears. Legal holds 100% exposure risk from consent bypass and fingerprinting. Enriched profiles accessible to competitors via data marketplace.
Risk Channel Breakdown
Signal corruption (25) from behavioral data collection distorts attribution. Theirstack captures visitor sessions before consent, injecting competitor-accessible intelligence into marketing analytics.
CAC subsidization (90) represents near-total value transfer. Visitor behavioral data feeds enrichment databases where competitors access company intelligence, firmographic data, and intent signals derived from YOUR traffic. You pay infrastructure costs; competitors harvest enriched profiles.
Expands attack surface
Legal tail risk (100) from GDPR/CCPA violations. Pre-consent activation, behavioral biometrics, and fingerprinting create regulatory exposure. Consent bypass defeats CMP controls.
