Gain Unprecedented Visibility Into Client-Side Security

In today's web, third-party scripts are essential but also create a significant attack surface. Page Shield gives you the tools to monitor these scripts, detect threats, and protect your users' sensitive data from client-side attacks.

How It Works

Resource Monitoring

Get a complete inventory of all scripts, connections, and cookies loaded by your website's visitors. This visibility helps you understand your client-side attack surface and identify any unauthorized resources before they become a problem.

Malicious Activity Detection

Leverage Cloudflare's vast threat intelligence and machine learning to detect malicious activity in real-time. Page Shield identifies threats like Magecart-style data skimming, crypto mining, and malware injection.

Code Change Detection

Receive immediate alerts when any of your existing scripts change. This helps you catch unauthorized modifications to your client-side dependencies, a common vector for sophisticated supply chain attacks.

Protect Your Business and Your Customers

By securing your client-side, you protect your brand's reputation, prevent costly data breaches, and build user trust. Page Shield offers a proactive defense against this often-overlooked threat vector.

Achieve PCI DSS 4.0 Compliance

Page Shield directly addresses key client-side security requirements in the Payment Card Industry Data Security Standard (PCI DSS) v4.0, which are mandatory for merchants starting in March 2025.

Requirement 6.4.3

Manage all JavaScript loaded on payment pages. Page Shield discovers and inventories all scripts, allowing you to build and enforce policies to ensure only authorized code executes.

Requirement 11.6.1

Detect and alert on unauthorized changes. Page Shield's code change detection and malicious script alerts provide the necessary mechanisms to assure script integrity on payment pages.
