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 Sojern 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

Sojern operates as a travel industry DSP deploying session recording, consent bypass, identity resolution, and tag manager capabilities across hospitality/travel properties. Oracle impact stems from session replay capture. Broker impact reflects identity resolution enabling cross-property demand signal correlation. Counselor impact derives from tag manager initialization ahead of consent. Reaper impact minimal despite tag infrastructure.

Customer Impact

What This Means For You

Hotels and airlines using Sojern face session recording liability exposing guest PII and payment flows. Identity resolution creates persistent profiles linking travel searches across competitive properties. Tag manager enables Sojern to add tracking partners without customer awareness or consent.
