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.
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
Detect 0-day attacks
c/side is crawling many sites to get ahead of new attacks. c/side is the only fully autonomous detection tool for assessing 3rd party scripts. We do not rely purely on threat feed intel or easy to circumvent detections. We also use historical context and AI to review the payload and behavior of scripts.
1 million scripts processed in last 24h
All scripts get processed by us to continually enhance our detection capabilities. We monitor over 70 attributes and use various AI-driven techniques to review the scripts, making our solution the most advanced detection system in the space to date.
Works with your favorite stack
