Our mission

# Help us secure our browsers

At CentralCSP, our goal is to make client-side security something every team can actually reach. Servers are hardened, monitored, and patched, but the browser is where your users meet your code, and it stays the weakest spot. We help companies see, prove, and protect what runs in their visitors' browsers, with no agent and no code changes.

The challenge we faced

## Client-side security is hard to get right

As web security engineers and developers, we lived the complexity of Content Security Policy firsthand. Every project brought broken features, endless policy tweaks, and hours lost debugging violations.

### The client side is a blind spot

WAFs and SIEMs stop at the server. The third-party scripts, trackers, and injected code running in your users' browsers stay invisible.

### CSP is hard to build and maintain

Writing a Content Security Policy by hand takes weeks, and a single strict directive can silently break checkout, analytics, or login in production.

### Supply-chain risk meets PCI DSS v4

Third-party scripts get hijacked to skim data, while PCI DSS v4 now requires you to inventory and monitor every one, hard to meet and to prove.

The solution

## So we built CentralCSP

We created CentralCSP to solve these challenges. The platform automates client-side security: real-time monitoring, real-traffic-based policy recommendations, vulnerable-script detection, and compliance insight. What used to take weeks now takes minutes.

Our story

## An endless evolution

We started small and shipped relentlessly. Every year added a layer, from a first scanner to billions of reports and enterprise-grade protection, always driven by the same mission.

1.  2024
    
    ### A scanner for CSP
    
    CentralCSP began as a simple Content-Security-Policy scanner, then grew into a platform to track CSP violations from real browser traffic.
    
2.  2025
    
    ### Growing into a platform
    
    We expanded fast, building for PCI DSS v4 and adding deeper CSP capabilities across the platform.
    
3.  2026
    
    ### Enterprise scale
    
    We scaled to billions of reports, shipped enterprise-grade features, and now ingest every report type the browser Reporting API can send.
    
4.  Now
    
    ### The mission continues
    
    We keep making the client side more secure, turning monitoring into strong protection and real security insight.
