What is TAG?

The Trustworthy Accountability Group (TAG) is the leading global initiative fighting criminal activity and increasing trust in the digital advertising industry. TAG advances its mission of eliminating fraudulent traffic, facilitating the sharing of threat intelligence, and promoting brand safety by connecting industry leaders, analyzing threats, and sharing best practices worldwide. The 600+ member TAG community include the world's largest and most influential brands, agencies, publishers, and ad tech providers.

TAG is the first and only Information Sharing and Analysis Organization (ISAO) for the digital advertising industry. This U.S. Department of Homeland Security designation means TAG is the primary forum for sharing threat intelligence in our industry.

TAG was created by the American Association of Advertising Agencies (4A's), Association of National Advertisers (ANA), and Interactive Advertising Bureau (IAB) and works collaboratively with companies throughout the digital ad supply chain.
