Fully PCI DSS v4.0.1 - requirements 6.4.3 and 11.6.1 compliant. Why the client-side? Client-side attacks using the browser of the user are on the rise. Millions of websites - and their users - are targeted every year, exfiltrating the data through JavaScript. We monitor all those script requests and sniff out malicious attempts. Why c/side? We are the only company in this space that uses a proxy service. This allows us to see all the code in real time and block 0-day attacks. Latency is highly mitigated through faster delivery and caching for the scripts that aren't loaded async. Compliance? By the 31st of March 2025, most companies need to be compliant with requirements targeting 3rd party JavaScript in the browser. If you process payments on your site, you are susceptible to comply.
