🛡️ Best Practices

                        
    
                            
  • Always test headers in a staging environment first
    • 
                            
  • Start with strict policies and loosen as needed
    • 
                            
  • Use CSP Report-Only mode during development
    • 
                            
  • Enable HSTS preload only after confirming HTTPS works
    • 
                            
  • Regularly review and update your security headers
    •
