In the rapidly evolving digital landscape of April 2025, secure file transfer is a cornerstone for business operations, especially as cyber threats grow more sophisticated. This survey note compares traditional Secure File Transfer Protocol (SFTP) with modern Managed File Transfer (MFT) solutions, highlighting why organizations must upgrade for enhanced security and efficiency. It also explores how SFTP and enumeration enable lateral movement by viruses and hackers, and how protocols like IBM Sterling Connect:Direct mitigate these risks.
Understanding Traditional SFTP and Its Limitations
SFTP, or Secure File Transfer Protocol, is an encrypted version of the File Transfer Protocol (FTP), using SSH for encryption to protect data during transit. According to What is Managed File Transfer (MFT)? | Globalscape, SFTP is particularly useful for businesses seeking to enhance the security of file transfer operations and user access. Its key benefits include:
Encryption: Data is encrypted, safeguarding it from interception during transfer.
Authentication: Supports secure methods like public key authentication to verify users.
However, SFTP has significant limitations that make it less suitable for modern business needs, especially in large-scale environments:
Lack of Centralized Management: Each SFTP server must be managed individually, leading to complexity and increased risk of misconfiguration. As noted in MFT vs. SFTP: Six benefits of modern Managed File Transfer, this decentralized approach can hinder visibility and control.
No Built-in Automation: File transfers often require manual intervention, which is inefficient for high-volume data exchanges and prone to human error, as highlighted in What is Managed File Transfer (MFT)? | IBM.
Vulnerability to Enumeration: Hackers can exploit SFTP to gather information about the system, such as directory structures, file names, and user lists, through enumeration. This process, defined in Cyber Security – Types of Enumeration | GeeksforGeeks, involves gathering network details to identify vulnerabilities, enabling lateral movement within the network.
The Rise of Managed File Transfer (MFT)
Managed File Transfer (MFT) is a comprehensive technology platform that manages all aspects of file transfer, including security, automation, and compliance. Unlike SFTP, which is a protocol, MFT is a full system that can utilize various protocols, including SFTP, for file transfers. According to What is Managed File Transfer (MFT)? | IBM, MFT is designed to reliably exchange electronic data securely and in compliance with regulations, outpacing traditional methods like FTP and SFTP.
Key features of MFT include:
Centralized Control: A single platform to manage all file transfer activities, simplifying administration and enhancing visibility, as noted in Managed file transfer - Wikipedia.
Automation: Automated scheduling and transfer processes reduce manual errors and improve efficiency, with features like checkpoint restart ensuring reliable delivery, as seen in What is Managed File Transfer (MTF)? - IT Glossary | SolarWinds.
Enhanced Security: Supports advanced security measures like multi-factor authentication (MFA), encryption, and access controls, providing a more robust defense against cyber threats, as detailed in 6 Reasons Why Managed File Transfer is Better than FTP.
Compliance and Auditability: Extensive logging and reporting capabilities help meet regulatory requirements such as GDPR and PCI DSS, as discussed in What is Managed File Transfer: The Ultimate Guide to MFT.
Comparing SFTP and MFT: A Detailed Table
To illustrate the differences, consider the following comparison:
Feature | Traditional SFTP | Modern MFT (e.g., Connect:Direct) |
Encryption | Yes, uses SSH for data in transit | Yes, with additional layers like TLS |
Authentication | Secure, supports public key | Supports MFA, SSH keys, and certificates |
Access Control | Limited, server-specific | Granular, centralized management |
Automation | Minimal, manual processes | Automated scheduling, checkpoint restart |
Auditing and Logging | Limited or none | Extensive logs, compliance reporting |
Scalability | Limited for high-volume transfers | Optimized for high-volume, reliable delivery |
Security Against Lateral Movement | Vulnerable to enumeration and exploitation | Prevents through controlled access and monitoring |
This table underscores why MFT is a superior choice for modern businesses.

Prevention of Lateral Movement: MFT’s controlled environment reduces the risk of hackers moving within the network through enumeration, a significant advantage over SFTP, as seen in What Is Lateral Movement? | IBM.
The Risks of SFTP and Enumeration in Lateral Movement
Hackers can exploit SFTP for lateral movement in the following ways:
Enumeration Defined: Enumeration is the process of gathering information about a target system or network, such as usernames, machine names, and shares, to identify vulnerabilities. In network security, this is a critical step in reconnaissance, as detailed in Cyber Security – Types of Enumeration | GeeksforGeeks.
SFTP Vulnerabilities: Despite encryption, SFTP can be targeted by brute force attacks and is vulnerable if server software is outdated. For example, weak password policies can be exploited, as noted in SFTP Vulnerabilities and Strategies to Secure Your File Transfers. Hackers can use SFTP to list directories and files, gathering intelligence that helps them move laterally—spreading within the network to access more systems, as discussed in What is Lateral Movement? | CrowdStrike.
Enabling Lateral Movement: Once hackers gain access to an SFTP server, they can enumerate connected systems, exploiting weak points to expand their control. This combination poses significant risks, especially in environments where SFTP servers are not properly secured.
