TL;DR: Legacy FTP transmits usernames, passwords, and file contents in plain text, leaving sessions exposed to interception and brute-force abuse while SecurityScorecard’s article recommends encrypted alternatives such as SFTP, FTPS, and managed file transfer controls. Plaintext file transfer is now a governance problem, not just a protocol flaw, because exposed transfer paths can become an identity and data exfiltration entry point.
Editorial analysis by NHI Mgmt Group, based on content published by SecurityScorecard: “FTP Security Risks, Vulnerabilities & Best Practices Guide”.
Key questions
Q: What breaks when organisations keep using plaintext FTP for sensitive transfers?
A: Plaintext FTP breaks confidentiality and weakens accountability at the same time.
Q: Why does unencrypted file transfer create identity risk?
A: Because the authentication step is part of the traffic itself.
Q: What are the signs that FTP is failing as a control?
A: Repeated failed logins, anonymous access, weak passwords, and file transfers from unexpected networks are all signs that FTP is no longer operating as a controlled service.
Practitioner guidance
- Replace plaintext FTP with encrypted transfer controls Move sensitive workflows to SFTP, FTPS, or managed file transfer services that enforce encryption for both credentials and content.
- Inventory every FTP endpoint and account Identify all servers, integrations, vendors, and automation jobs still using FTP, then classify the data and identities they expose.
- Disable anonymous access and weak authentication Remove default logins, require strong passwords or key-based authentication where available, and review whether any FTP account still needs to exist.
Bottom line: Legacy FTP exposes both credentials and file contents, which makes interception a live risk rather than a theoretical weakness.

Plaintext transfer is an identity exposure problem, not only a protocol problem. FTP turns login material into network traffic, which means access control depends on the absence of observers rather than on a governed authentication boundary. That is a weak model for any environment that handles sensitive data, and it becomes harder to defend when credentials are reused elsewhere. Practitioners should treat insecure transfer paths as part of identity attack surface.
A question worth separating out:
Q: Should organisations keep FTP when SFTP or FTPS is available?
A: Only for narrow legacy cases with compensating controls and a defined retirement plan. In most environments, SFTP or FTPS is the better operational choice because it encrypts authentication and content, improves auditability, and reduces the chance that a routine transfer becomes a breach path.
