Page Shield
Client-side protection against Magecart
Page Shield protects websites against client-side attacks such as Magecart, formjacking, and cryptojacking, which account for 38% of all e-commerce breaches. The system monitors all JavaScript scripts executed in users' browsers, detecting new resources, code modifications, and suspicious behavior such as keylogging or exfiltration to unknown domains. Automatic alerts notify teams of changes in the third-party vendor supply chain. Content Security Policy (CSP) blocks unauthorized scripts.
