• Restrict FTP Accounts: Limit account access to specific directories (e.g., /public_html) in cPanel.
• Hosting Security: Choose a provider like RSH Web Services with free SSL, DDoS protection, and secure servers.

Warning: The FBI (2023) highlighted vulnerabilities in unencrypted FTP; always use SFTP or FTPS for secure transfers.

• Certificate Errors: Accept “Unknown Certificate” warnings for trusted servers or verify SSL settings for FTPS.
• Slow Transfers: Optimize your internet connection or use bandwidth control in Cyberduck’s Preferences → Bandwidth.
• Directory Errors: Ensure the specified path (e.g., /public_html) exists in cPanel’s File Manager.
