Safer browser headers
Security headers help reduce clickjacking, content sniffing, unsafe embeds, cross-origin exposure, and accidental insecure loading.
Production Readiness · Build 603
Security Hardening
ToolsBing is designed to help people use online tools safely. This page explains the security protections added before production launch.
Protected internal files
Server rules block access to internal include files, configuration-style files, logs, backups, package files, and hidden system files.
Form safety foundation
Build 603 adds CSRF helper functions and POST request protection so future interactive features can be secured consistently.
Production-safe defaults
Error display is discouraged in production, HTTPS is enforced, and sensitive development artifacts are blocked from public access.
Important: security is an ongoing process. Before launch, confirm hosting-level SSL, backups, firewall rules, PHP version, file permissions, and dependency updates.
