CSP Header Security Scanner

A tool that scans Content Security Policy headers and explains in plain English what security vulnerabilities or misconfigurations exist. Helps developers quickly fix security issues without needing deep CSP expertise.

CSP misconfigurations remain one of the most commonly overlooked web vulnerabilities, and with increasing regulatory pressure around web security (PCI DSS 4.0 now explicitly calls out CSP requirements), developers are being pushed to care about headers they've historically ignored. Mozilla Observatory and SecurityHeaders.com already do something close to this for free, which is the core problem — the substitutes are good enough for most use cases, and "explain it in plain English" is roughly a one-time GPT wrapper away for anyone who already uses those tools. The revenue band is honest given the dynamic: this is a low-switching-cost utility that would need aggressive upselling into CI/CD integrations or team reporting to justify any subscription. The most likely failure mode is that the free tier of competitors absorbs all the demand and there's no wedge to convert even modest traffic into paying users.
