Implementing cside is dramatically simpler than deploying a WAF. A WAF requires changing DNS records, setting up SSL certificates, testing, and configuring firewall rules before deployment in production, potentially restructuring your entire web infrastructure. Cside implementation is just adding our NPM package or one script tag to your pages and configuring which third-party scripts you want analyzed through our dashboard. You can have a proof-of-concept running in minutes on our free plan, not weeks like a WAF deployment.
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.
