Most privacy programs rely on a consent management platform (CMP) to display banners and record user preferences. But what happens after users make a choice?
Previously, the Jscrambler Security Research team found that popular third-party pixels routinely bypass correct consent configurations, capturing sensitive user data before a choice is made or even after users click “Reject All”.
A CMP is designed to gate whether a script is loaded, but it has little control over what third-party scripts, like Meta, LinkedIn, or TikTok pixels, actually do once they run.
With privacy litigation surging, organizations are increasingly expected to prove what the browser actually executed, not just what the banner displayed.
What We Will Cover:
- How CMPs operate, where their authority stops, and why rogue scripts bypass consent.
- Where regulators are pivoting focus toward actual browser behavior and why recent legal updates (SB690) aren’t safe harbor
- How runtime enforcement adds an active defense layer to observe and block unauthorized browser data leaks in real time.
- How CMPs and browser runtime controls combine to eliminate privacy blind spots.
- Practical steps to audit sensitive data flows, correct default vendor behaviors, and maintain continuous privacy oversight.
