Negative press, potential lawsuits, and damage claims following a security incident.

It's Time to Take Action

PCI DSS 4.0 (specifically 6.4.3 and 11.6.1) mandates entities handling card data to implement tamper-detection mechanisms by March 31st, 2025. This aims to mitigate Magecart attacks by alerting on unauthorized changes to HTTP headers and payment content.
