Server-Side Tagging: Security Tradeoffs Explained

Server-side tagging can reduce browser exposure, but it does not remove the need for consent-aware routing, vendor review, and destination controls.

• Better control over outbound destinations
• Less client-side script weight
• Centralized enrichment and filtering

}
forwardEvent(event)
