Summary

TAG’s certification programs, compliance tools and intelligence-sharing set trusted benchmarks to fight criminal activity across digital advertising that protect the industry. Through the AdSec Threat Exchange, TAG strengthens the global community’s collective defense against evolving digital threats.

The 2025 TAG Impact and Compliance Report builds on last year’s data to track progress, metrics, and milestones—offering a fact-based snapshot of impact and opportunities for improvement, while guiding measurable enhancements across TAG’s programs.

Key findings include:

TAG’s Global Reach

• TAG Members span 37 countries worldwide. 
• TAG’s Community now includes 434  leading companies across every segment of the digital advertising industry worldwide.

• Strong research-backed evidence continues to accumulate on the dramatic savings from the industry’s anti-fraud programs. A new study found that anti-fraud initiatives saved European advertisers €3.45B in ad fraud losses, but left more than €1B in unrealized savings on the table due to gaps in adoption.

Malvertising

• A focus on sharing high-value intelligence like tactics, techniques, and procedures paid dividends for the Malvertising Threat Exchange (MTX) with an 82% year-over-year increase in the sharing of such high-value intel.

• According to the ANA’s Q3 2025 Programmatic Transparency Benchmark, industry steps in key transparency-related areas have helped marketers reclaim $13.6 billion in value, while driving MFA spending below 0.5% for the first time.

• A new metric in the ANA benchmark focused on normalized brand safety and suitability found that industry brand safety programs are creating a safer supply chain, with 99.1% of ad spend spent in low-risk environments.

TAG’s Due Process for Non-Compliance and Appeal

• After investigating allegations around industry monetization of Child Sexual Abuse Material (CSAM), TAG organized a first-of-its-kind briefing by an executive with the National Center for Missing and Exploited Children (NCMEC) to provide valueable trainingexpert counsel and tips to TAG members on how to identify and refer such material to law enforcement.

Compliance Tools

• TAG tools continue to be strengthened and improved with updates, fine-tuning, additions, and deduplication. For example, the Data Center IP (DCIP) list was updated monthly over 2025 and ended the year with nearly 68 million IP addresses.
