2023 Feroot Client-Side Security Report

Beware of Pixels & Trackers on U.S. Healthcare Websites.

We all know tracking pixels are critical for Marketing teams to track website visitors and serve up ads. But do you know who else is getting a copy of your customer’s data? This is the question we set out to uncover.


Uncover Your Client-Side Attack Surface

Discover the complex web of third-party code, and the risks they bring, each time you access a web page.

Stay Ahead of Privacy Violations

With Feroot you not only see every third-party technology across your web application, but also which of those third-parties have access to customer data.

Some of Our Numbers


Platform Uptime


Events Processed


Web Pages Analyzed


Revenue Protected

Existing Controls Leave Gaps

Legacy Controls Don’t Work on JavaScript

CI/CD, SAST/DAST, code scanning, can’t protect against side-loaded JavaScript attacks and data leaks.

WAFs and CSP Leave Data Exposed

Traditional controls including WAFs and CSP work well until marketing adds a tag manager.

Cookies Don’t Tell the Full Story

Pixels and trackers may set cookies, but that’s not the only way they can access customer data.

Increased Attack Surface

The heavy use of third-party tools and libraries can drastically increase your client-side attack surface.

Frederick “Flee” Lee

A day doesn’t go by that you don’t hear about a new JavaScript-based attack on a company’s website or web application. We’re seeing attackers pivoting from traditional server-side attacks to client-side attacks. To protect our business from server-side threats, we needed to enhance our client-side security capabilities to stay ahead of the threat. ”
