64% of Third-Party Apps Access Your Data Without Permission! | Web Exposure Management (2026)

A shocking revelation has emerged from recent research: a staggering 64% of third-party applications are accessing sensitive data without any valid business reason, and this number is on the rise. This is a critical issue that demands our attention!

The study, which analyzed over 4,700 leading websites, paints a worrying picture. It highlights a growing governance gap, where marketing and digital teams are deploying apps without proper IT oversight, leading to chronic misconfiguration and unnecessary data exposure.

But here's where it gets controversial... Some specific offenders stand out: Google Tag Manager, Shopify, and Facebook Pixel. These tools, which are widely used, account for a significant portion of the unjustified data access. For instance, Facebook Pixel, with its 'Full DOM Access' permission, could potentially become a massive single point of failure, affecting millions of websites simultaneously.

The research also reveals a disconnect between security leaders' awareness and their actions. While 81% of them prioritize web attacks, only 39% have implemented solutions to address this issue. This awareness-action gap leaves organizations vulnerable to increasing risks.

And this is the part most people miss... The study identifies the 'Marketing Footprint' as a key driver of these risks. Marketing and Digital departments are now responsible for a significant portion of third-party risk exposure, often deploying tools without fully understanding the security implications.

The consequences are severe, especially for critical infrastructure sectors like government and education, where breaches are skyrocketing. These institutions, constrained by budgets and manpower, are struggling to keep up with the evolving threats.

So, what can be done? The research suggests a few quick wins: auditing trackers, implementing automated monitoring, and bridging the divide between marketing and IT teams. By taking these steps, organizations can start to close the governance gap and better protect their sensitive data.

Download the full report for a deeper dive into these findings and to explore practical solutions. It's time to take action and address this growing threat!
