Protect against client-side threats

Third-party scripts on your site can be compromised to exfiltrate data or inject malicious code. Cloudflare's client-side security (previously known as Page Shield) monitors every JavaScript resource loading on your pages, detects suspicious behavior, and helps you manage Content Security Policies (CSPs).
