Bot Defender Product Brief
Code Defender Product Brief

Integration Overview

Modern websites are shifting logic to the client side to increase performance and enrich the user experience. They also make extensive use of third-party scripts and open-source libraries to innovate faster and deliver rich new capabilities. In fact, almost 70% of the scripts on a typical website are third-party.

These scripts run on the client side, outside of the site owners’ visibility or control, creating a major blind spot. Client-side attacks like Magecart and digital skimming can leak your users’ data right from the browser, leading to the theft of credit card numbers and other personally identifiable information (PII). With over 20,000 domains already compromised, Magecart attacks are the most serious security threat to online businesses today, leaving you exposed to compliance penalties, brand damage and loss of revenue.

With the PerimeterX Code Defender cartridge, website owners and developers can gain full visibility into script activity on the users browser, detect unauthorized PII access, data exfiltration events and known script vulnerabilities.

The Code Defender cartridge includes a lightweight JavaScript Sensor that works with the cloud-based Detector to help you detect and mitigate digital skimming and Magecart attacks.
