4.4 Security considerations for portable use

• Storing credentials locally in portable config files poses risk if the portable package is moved or stored on insecure media. Credentials saved in Site Manager may be encrypted or obfuscated depending on the version; older releases often used reversible obfuscation or plain text.
• Private keys stored alongside the portable client are vulnerable if the media is lost.
• TLS/SFTP security depends on the underlying libraries shipped with the portable build; unpatched older builds may lack mitigation for known vulnerabilities.

In shared workstation environments, users often lack the administrative privileges required to install new software.
