Writing a good Content Security Policy is hard; maintaining it over time is way harder. Attackers can easily compromise approved CDNs or leverage trusted domains to bypass these basic protections. With CSP, you don’t have script payload visibility, creating an allowlist for the source but not restricting its actions. Cside provides deep payload analysis, AI-driven threat detection, and complete forensic history that basic solutions can't match. When you're dealing with PCI compliance and customer data protection, you need a solution that actually works, not just one that checks a compliance box.
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.
