Secure File Transfer is the process of transmitting data between systems or users using encrypted protocols to ensure confidentiality, integrity, and authenticity. Unlike standard file transfer methods such as FTP, which send data in plaintext, secure file transfer methods like SFTP, FTPS, HTTPS, and SCP protect files during transit by encrypting both the payload and session. Secure file transfer is a core function in cybersecurity frameworks, especially in critical infrastructure environments where data exchange must meet stringent regulatory and operational requirements.
Secure file transfer is vital for protecting sensitive data from interception, tampering, and unauthorized access, especially when files are exchanged across organizational boundaries or remote networks. In critical infrastructure environments such as energy, manufacturing, and transportation, improperly secured transfers can result in data leakage, ransomware propagation, or compromise of control systems.
Regulations like IEC 62443, NERC CIP, TSA SD02E, and Saudi OTCC-1:2022 require encrypted communications, audit trails, and access controls for any data exchanged with operational systems. Traditional file-sharing tools or legacy FTP solutions often fall short of these requirements. Secure file transfer not only addresses the technical need for encryption but also supports compliance through features like role-based access, session logging, and administrative oversight. This makes it a foundational control for both secure operations and regulatory alignment.
Xona delivers secure file transfer capabilities purpose-built for Operational Technology (OT) environments. Unlike traditional file-sharing or PAM-integrated tools, Xona enables moderated, policy-controlled file transfer directly within the secure session context, enforcing security without requiring users to switch platforms or tools.
Files are transferred through Xona’s hardened gateway using encrypted channels, and every transaction is authenticated, monitored, and logged in real time. Administrators can enforce file-type restrictions, malware scanning, and real-time approvals, ensuring operational safety and compliance with standards like IEC 62443 and NERC CIP.
