Reflectiz & Taboola: Securing Third-Party Marketing in the AI Era  

Every third-party marketing vendor you approve has the potential to silently introduce fourth-party scripts you never vetted. In the AI era, that invisible layer is growing faster than security teams can track.

About this session

Marketing stacks have grown into complex, dynamic ecosystems where a single approved vendor tag can trigger dozens of unauthorized third and fourth parties that nobody on your security team ever reviewed. The gap between what you approved and what is actually running on your site is where regulatory exposure, data leakage, and compliance failures happen.

In this session Idan Cohen, CEO of Reflectiz, and Omri Ariav, Director of Product at Taboola, bring together the security and ad tech perspective to address this web security gap that sits between your approved vendor list and what is actually running on your site.
