How to maintain digital agility without losing control of third-party scripts or failing your next audit.

Security and compliance leaders are under pressure to support fast-moving marketing teams—without opening the door to eSkimming, formjacking, or PCI violations. This guide shows you how.

• Understand the real risk of tag managers – Learn how GTM, Tealium, and others function as code deployment platforms—giving unchecked JavaScript runtime access to your most sensitive pages.
• Translate PCI DSS 6.4.3 and 11.6.1 into action – Break down the new compliance mandates and what they actually require from your teams—script control, change detection, and audit evidence.
• See why CSP and SRI aren’t enough – Understand the technical and operational reasons traditional controls fall short in dynamic, tag-driven environments.
• Get a clear path to compliance without slowing down – Discover how behavioral controls, real-time monitoring, and policy enforcement can make your tag manager safe—without adding friction for marketing
