I will secure ur frontend and implement advance content security policy to prevent XSS


About this gig
Hello, great clients, welcome to my gig
Frontend security is no longer optional. If your website lacks a properly configured Content Security Policy (CSP), it is vulnerable to XSS attacks, script injection, and malicious third-party resources.
I will secure your frontend by implementing an advanced Content Security Policy tailored to your application. Whether you use React, Next.js, Vue, static HTML, or any custom frontend, I will configure CSP headers correctly without breaking functionality.
This includes XSS protection, script-src optimization, nonce or hash configuration, strict-dynamic setup, and proper security headers implementation.
I focus on clean implementation, performance-safe policies, and production-ready deployment. You will receive a secure, optimized configuration that protects your users and strengthens your website security posture.
Lets harden your frontend properly and professionally.
