ABC clients recognised in latest TAG certification release, reinforcing industry trust in digital advertising

06/03/2026

The Trustworthy Accountability Group (TAG) is a global initiative dedicated to combating criminal activity and strengthening trust in digital advertising. Its certification programmes - Brand Safety Certified (BSC), Certified Against Fraud (CAF) and Certified Against Malware (CAM) - set industry standards designed to reduce fraud, prevent ad misplacement and protect users from malicious activity across the advertising supply chain.

Achieving a TAG Seal demonstrates that a company has implemented policies, processes and controls aligned with TAG's guidelines. Independent validation provides credible third-party assurance that these standards are being met, enabling organisations to demonstrate their commitment to responsible trading and greater transparency.

Mike Zaneis, President & CEO of TAG, commented:

As digital advertising becomes more automated and more complex, trust must be earned, not assumed. TAG's standards reduce fraud, strengthen brand safety and promote accountability across the supply chain - and independent auditing by our long-standing partner, ABC, ensures those standards carry real weight.

Simon Redlich, CEO of ABC UK, added:

Achieving a TAG Seal sends a strong signal to the market that a business takes transparency and responsible trading seriously. Independent validation gives that commitment real weight.

ABC congratulates all clients listed below who've successfully achieved TAG certification. Their commitment to industry best practice plays an important role in strengthening confidence across the digital advertising ecosystem.
