cside fully satisfies both PCI DSS controls through its hybrid proxy approach. For requirement 6.4.3, we continuously monitor and hash every third-party script before it reaches your users' browsers. For 11.6.1, we track all changes to security headers and script contents with complete historical records. VikingCloud–one of the highest-reputation global security assessors -  independent assessment confirms that the cside platform meets these requirements when properly configured. You get automated compliance reports that map directly to PCI testing procedures, making audits much easier.
