Cside operates at the browser JavaScript engine level. It works identically with any framework, including React, Angular, Vue... Subrequests are automatically rewritten and analyzed just like any other resource. Cside adapts to your existing tech stack without requiring major architectural changes.
CSP is a great base-layer for client-side security, but it cannot see script contents. Depending on your needs and risk profile, it may or may not be sufficient.
PCI DSS requires monitoring scripts for changes. CSP can only control sources, not inspect payloads, so it cannot meet PCI DSS requirements.
We fundamentally believe every individual and operation should be able to secure themselves, regardless of resources.
Because client-side security monitors an entirely different dimension of the application stack, there is no interference.
