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.
The value we add
How we're different
- Real time flow-through monitoring
- No sampling, we cover 100%
- Caching scripts, making them faster
- Detection mechanisms that actually work
- Using AI to make findings easily understandable
