Charles River Associates — AdTech forensics

Forensic AdTech analysis, remediation, and testimony.

Deep expertise in pixels, SDKs, cookies, tag managers, consent frameworks, and browser privacy mechanisms — enabled by proprietary tools that support the automated collection and analysis of network traffic, client-side code, and historical site configurations.

  • Network traffic
  • Tag management
  • Source code
  • Consent platforms

Your AdTech stack

A growth catalyst

Measurement, attribution, and audience activation drive the revenue engine of the modern enterprise.

The same stack

A risk multiplier

Every tag, pixel, and vendor is also a data flow that regulators, plaintiffs, and courts now examine in detail.

01 — Platform

Automation to deliver across all types of ecosystems.

Whether engaged for a single point-in-time assessment, a historical privileged investigation, or ongoing monitoring, we support engagements from single-domain reviews to analysis across a thousand-plus digital properties.

Consent & tag manager monitoring

01

Review historical container configurations to track behavior evolution over time.

Tag management platform monitoring

06

Tag management platform monitoring

Continuous monitoring of container configurations to detect unauthorized changes.

02 — Approach

Your CMP is not a governance tool. It is a signaling tool — with multiple points of failure.

A consent management platform does not directly control whether an online tracking technology fires.

Tag managers, customer data platforms, authentication systems, AdTech vendors, and your own source code must each retrieve the signal and act on it — on the front end and the back end. We trace the signal through all of them and document exactly where it breaks.

03 — Coverage

Monitor every system, signal, and event.

01

Runtime opt-out

Verify opt-out-of-sale selections are honored at runtime across network traffic and tag management systems.

02

GPC signals

Track browser-level Global Privacy Control signals and their propagation through consent platforms.

03

Auditable receipts

Analyze consent receipts and documentation across consent management platforms and storage systems.

04

Standardized strings

Monitor IAB GPP and TCF consent strings across network traffic and programmatic ecosystems.

05

Compliant notices

Validate notice rendering and preference manager functionality across devices and source code.

06

Auto-blocking behavior

Observe domain blocking and tracker suppression across network traffic and tag configurations.

07

Persistence

Confirm consent status persists across browser storage, cookies, and cross-device synchronization.

08

CIPA suppression

Monitor time-based suppression behavior across network traffic and tag management systems.

09

Forensic reporting

Synthesize findings from every source into evidence-grade reports for investigations and litigation.

04 — Engagement

How we work.

01

Forensic collection

We capture browser-level network traffic, tag management configuration, source code, and CMP behavior to reconstruct the complete picture — not a sample of it.

02

Data-flow validation

We validate that signals from the CMP are correctly received and acted upon by every downstream system and vendor, and document where they are not.

03

Ongoing Monitoring & Support

Continuous observation and on-call subject-matter experts translate findings for business, legal, and regulatory audiences.

04

Expert Testimony

Subject-matter experts carry findings through to expert testimony when legal or regulatory proceedings require it.
