6 Secure FTP Alternatives for Safe File Transfers in 2025

File Transfer Protocol (FTP) has been around since the 1970s, and while FTP's original protocol has been the go-to for moving files between computers, it’s showing its age. FTP sends data in plaintext, leaving it vulnerable to interception, and lacks modern security features like encryption or multi-factor authentication. As cyber threats grow and businesses demand safer, more efficient ways to share files, it’s time to look beyond FTP. In 2025, secure alternatives like SFTP, FTPS, AS2, HTTPS, MFT, and client portals are leading the charge. These options offer better security, automation, and user-friendliness to meet today’s needs.

In this blog, we’ll explore six FTP alternatives, breaking down their strengths, use cases, and why they’re better suited for modern file transfers. Whether you’re a small business, an IT admin, or just looking for a safer way to share files, there’s an option here for you. Let’s dive in!

Why Replace FTP?

Before we get into the alternatives, let’s talk about why FTP is falling out of favor. FTP was designed for a simpler time when security wasn’t a major concern. Today, its flaws are hard to ignore:

• No Encryption: FTP sends files, usernames, and passwords in plaintext, making it easy for hackers to intercept sensitive data. Learn more about data interception risks from the Electronic Frontier Foundation.
• No Authentication Options: FTP lacks modern security features like multi-factor authentication (MFA) or SSH key support.
• Firewall Issues: FTP uses multiple ports, which can complicate firewall configurations and slow down transfers.
• Compliance Risks: Regulations like GDPR, HIPAA, and PCI-DSS require secure data handling, which FTP can’t guarantee.

With browsers like Chrome, Firefox, and Edge dropping support for FTP connections, it’s clear the industry is moving on. Modern alternatives prioritize security, compliance, and ease of use, making them a better fit for businesses and individuals alike. Here are six top FTP alternatives to consider in 2025.

How to Choose the Right FTP Alternative

Choosing the best FTP alternative depends on your specific needs. Here are some factors to consider:

• Security Requirements: If compliance with GDPR, HIPAA, or PCI-DSS is critical, prioritize MFT or client portals with strong encryption and auditing.
• Ease of Use: For non-technical users, HTTPS or client portals (like Foyer's) are the most accessible.
• Volume and Complexity: Large organizations with high-volume transfers or automation needs should opt for MFT.
• Budget: SFTP and FTPS are cost-effective for smaller setups, while MFT and client portals may require subscriptions.
• Trading Partner Needs: If you work with partners using specific protocols (e.g., AS2 for EDI), choose a solution that supports those standards.

For a quick comparison:

1. SFTP (Secure File Transfer Protocol)

What is SFTP?

SFTP, or Secure File Transfer Protocol, is often confused with “secure FTP,” but it’s actually SSH File Transfer Protocol. It uses a Secure Shell (SSH) connection to encrypt data during transfer, ensuring that files, usernames, and passwords are protected from prying eyes. Unlike FTP, SFTP operates over a single port (port 22), making it firewall-friendly and easier to configure.

Why Choose SFTP?

• Strong Security: SFTP uses SSH encryption, safeguarding data in transit and preventing unauthorized access.
• Platform Independence: Works across Windows, macOS, Linux, and more, making it versatile for different environments.
• Authentication Options: Supports passwords, SSH keys, and two-factor authentication for added security.
• Ease of Use: Many FTP clients, like FileZilla and WinSCP, support SFTP, so you can use familiar tools.

Use Cases

SFTP is ideal for businesses needing secure, reliable file transfers, especially in industries like healthcare or finance where data protection is critical. It’s great for transferring large files or automating workflows with scripting support.

Drawbacks

• Requires SSH setup, which might be complex for beginners.
• Lacks advanced features like automation or centralized management compared to other solutions.

Why It’s Better Than FTP: SFTP’s encryption and single-port design make it far more secure and easier to manage than FTP, especially for sensitive data transfers.

2. FTPS (FTP over SSL/TLS)

What is FTPS?

FTPS, or FTP Secure, builds on traditional FTP by adding Transport Layer Security (TLS) or Secure Sockets Layer (SSL) encryption. It secures both the control and data channels, protecting files during transfer. FTPS operates in two modes: explicit (customizable encryption) and implicit (strict encryption via port 990).

Why Choose FTPS?

• Familiar Interface: FTPS feels similar to FTP, making it an easy transition for existing users.
• Robust Security: TLS/SSH Encryption ensures data privacy and integrity.
• Wide Support: Supported by popular FTP clients like FileZilla, Cyberduck, and Core FTP.
• Compliance: Meets standards like PCI-DSS and HIPAA, ideal for regulated industries.
