Best for

▸Designing nonce-based CSP policies for React/Next.js SPAs to prevent XSS attacks
▸Migrating from whitelist-based to strict-dynamic CSP policies without breaking third-party integrations
▸Implementing CSP violation reporting and monitoring for enterprise web applications
▸Configuring CSP headers for content-heavy platforms with user-generated content and embedded media
▸Troubleshooting CSP deployment issues with analytics, ads, and payment processor integrations

What you'll get

●Complete CSP header configuration with nonce generation code for specific frameworks, testing methodology, and rollback plan
●Step-by-step migration guide from current policy to strict CSP with violation analysis and third-party integration fixes
●Production-ready CSP monitoring setup with violation reporting endpoints, alerting rules, and policy refinement process

Not designed for ↓

×General web application firewall configuration or DDoS protection strategies
×Backend API security or database injection prevention beyond frontend context
×Mobile app security or native application content policies
×Network-level security or infrastructure hardening beyond browser security headers

Expects

Details about your web application's architecture, rendering model (SSR/CSR), third-party integrations, and current security headers implementation.

Returns

Specific CSP policy directives, deployment strategies with report-only testing phases, framework-specific implementation code, and violation monitoring setup.
