On August 18, 2014, Cloudflare introduced a new app called Tinfoil Security, which aims to identify web application vulnerabilities. While Cloudflare's security features focus on network-level protection, Tinfoil Security complements this by scanning for vulnerabilities at the application layer and providing detailed reports with step-by-step instructions on how to eliminate threats. The app offers various pricing plans, including a free option that checks for Cross-Site Scripting issues.
