I built an open-source scanner and analyzed 30 iGaming sites. They all failed.

Introduction
The online gambling industry processes billions of dollars daily. You would expect their security posture to be impenetrable. To test this hypothesis, I built ShieldScan, a passive reconnaissance tool, and ran a benchmark across 30 top iGaming platforms (crypto casinos, traditional bookmakers, and skin gambling sites).

The results were surprisingly poor.

The Methodology (Passive Recon Only)
Before diving into the numbers, it's important to note the methodology. ShieldScan operates purely through passive reconnaissance. No intrusive testing, no authentication bypasses, no payload injections. It relies entirely on:

HTTP Response Headers
DNS Records (SPF, DMARC)
TLS Certificate analysis
Public Certificate Transparency logs
The Shocking Results
Out of 30 platforms analyzed, 100% received a failing grade (F), with an average score of just 26/100.

Here is the breakdown of the most critical failures:

1. Content-Security-Policy (CSP) is Non-Existent Zero out of the 30 platforms implemented a restrictive CSP. In modern web development, CSP is your primary defense-in-depth mechanism against Cross-Site Scripting (XSS). Without it, any XSS vulnerability can immediately lead to account takeovers.

2. Email Spoofing is Trivial Over 90% of the sites lacked a strict DMARC policy (p=quarantine or p=reject). This means attackers can easily spoof emails from these domains to run highly effective phishing campaigns against high-roller players.

3. PCI DSS 4.0 Violations Despite processing payments, nearly all sites failed basic PCI DSS 4.0 requirements, specifically around header configurations (Req 6.4.3) and transmission security. ShieldScan flagged an average of 18 compliance violations per site.

Enter ShieldScan
I built ShieldScan to automate this exact type of analysis. It doesn't just list "missing headers"—it maps them to real-world impact.

Key features I implemented:

Attack Chain Visualizer: Maps how a missing configuration (like HSTS) leads to a real exploit (SSL Stripping).
Compliance Engine: Automatically flags violations for PCI DSS, OWASP Top 10, and GDPR.
PDF Report Generator: One-click professional audit reports.
Bulk Benchmarking: Scan up to 50 sites simultaneously.
Try it yourself
ShieldScan is completely open-source and built with zero external scanning dependencies (just native Node.js).

If you are a penetration tester, bug bounty hunter, or security engineer, you can use it to generate instant baseline reports for your targets.
