They take your traffic signals and stream them live to buyers.
Streaming data to external endpoints via WebSocket/SSE in real-time. Unlike batch collection, real-time exfil transmits visitor behavior, page interactions, and identity signals as they happen, enabling immediate action by third parties.
What It Costs You
CAC Subsidization
Visitor data captured on a site can flow into data broker networks and identity graphs, eventually surfacing in competitor prospecting tools. The original company paid to acquire the traffic; competitors pay pennies to intercept the lead.
Signal Corruption
Overlapping tracking mechanisms corrupt attribution data. Multiple sources claim credit for single conversions. Pipeline metrics diverge from reality. Marketing decisions get made on numbers that can’t be trusted.
GTM Attack Surface
Third-party scripts execute with full privileges on every page load. Dangerous code patterns, external dependencies, and data interception turn marketing infrastructure into attack vectors. One compromised dependency compromises the entire site.
