What to look for in an FTP/SFTP client?

The answer to this question is really “it depends”. If you are a home user or just manage a WordPress site or two, you may be able to get away with a very simple file transfer client. All you may need is a simple graphical user interface (GUI) and support for a protocol or two. On the other hand, if you are an advanced user or subject to specific compliance requirements, you may have a much more extensive list of needs when it comes to your FTP/SFTP client software needs. Below is a quick rundown of some of the features you may want to keep an eye out for:

  • Protocols & encryption method support – Do you know you will only ever need SFTP support? Are you in a role where one server uses SFTP, another FTPS, another HTTPS, and another FTP? Similarly, do you care (for compliance reasons or otherwise) about the security of the encryption methods your client software uses? You’ll need to consider these points when picking client software.
  • Drag & drop – This is a convenience feature, but drag and drop with client software GUIs can streamline the file transfer process.
  • File integrity checks – How do you know if the file you moved from location A to location B made it there without any corruption? Comparing the hash or checksum can help you do this. Some client software will take care of this for you.
  • Scheduling of actions – How much time will you save if you or your team can automate your file transfers? If you are in a medium or larger-sized business, automating the easy stuff can help save on Opex.
  • Connection limits – Do you need to be able to make unlimited FTP/SFTP connections or can you get away with just one or two?
  • Logging – For auditing, compliance, and troubleshooting, detailed logs can be essential. Does logging matter to you?
  • Synchronization & backups – Do you need to be able to sync files at two different locations automatically? Would automating a backup process save your team a ton of time? If yes, look for these features in your client software.

1. Files.com (FREE TRIAL)

Files - Users view
A more comprehensive cloud-based tool you can use from anywhere

Files.com is a file management service that can be used to consolidate all file movements. As such, the cloud service will act both as an FTP or SFTP server and a client.

Key Features:

  • FTP or SFTP: Files.com supports both FTP (File Transfer Protocol) and SFTP (Secure File Transfer Protocol), providing flexibility in file transfer methods.
  • Client and Server: It functions as both a client and server, allowing users to upload, download, and manage files remotely.
  • Backup Storage: Files.com includes backup storage capabilities, ensuring data redundancy and protection against data loss.
  • Security: The platform offers security measures for data both in transit and at rest, ensuring data privacy and integrity.
  • 7-Day Free Trial: Users can try out the platform with a 7-day free trial before committing to a subscription.

Why do we recommend it?

Files.com is a file transfer system that supports end users rather than technicians. It provides a secure way to eliminate the distribution of files to outsiders. Users upload their files over a secure connection to the Files.com server and email out an invite link instead. Users can control access to their files and revoke or limit the rights given to others.

The cloud service of Files.com acts as a secure buffer between your organization and the rest of the world and also creates a shared file space for collaboration. Files that are in transit get uploaded to the Files.com server and then the rest of the journey occurs virtually. The intended recipient of the file gets a link to access the file securely on the Files.com server. Settings on each file restrict the actions that each nominated recipient can perform on it, such as downloading it, altering it, or copying it.

The Files.com system can be used as a pass-through to other cloud storage services, such as Dropbox and Google Drive. The service also has online app integrations with productivity and collaboration software, such as Microsoft 365, so documents can be created, stored, and shared directly on the Files.com server. That eliminates the need for uploading and downloading files with FTP or SFTP.

Files devices
You can log in and send files from anywhere you have a device with an internet connection

Strictly speaking, FTP has no security. So, as all file transfers performed with Files.com are encrypted, it isn’t really an FTP service. The service implements FTP over TLS, which is better known as FTPS. SFTP, or SSH FTP, is implemented on Files.com using public keys provided by the ED25519, RSA, or DSA standards.

Files.com can interact with on-premises equipment as a mounted drive, through a web browser, or through desktop-based FTP utilities, such as CuteFTP or WinSCP. You can get a 7-day free trial of the Files.com service to see it for yourself.

Who is it recommended for?

This is a great tool for employees who need to regularly mail YouTube files. They can invite access to those files instead from their location on the cloud server. The system can become the primary file drive for an office community as well because it integrates with Microsoft 365 and email systems.

Pros:

  • OS Agnostic: Being cloud-based, Files.com is operating system agnostic, accessible from various devices and platforms.
  • Integration with Other Cloud Services: It supports integrations with popular cloud services like Google Drive and Dropbox, enhancing collaboration and workflow efficiency.
  • Link Sharing: Files can be shared via links, reducing download times and providing more control over file access and permissions.
  • Link Management: Links can be set to expire and managed through permissions, ensuring security and control over shared files.

Cons:

  • Learning Curve: Some of Files.com’s more advanced features may require time to fully understand and utilize effectively.

EDITOR'S CHOICE

Files.com is our top pick for an SFTP system that you can use from Windows or Linux because of its flexibility, security, and ease of use across multiple platforms. As a cloud-based file transfer service, Files.com offers seamless integration with existing workflows while providing reliable support for SFTP, FTP, and other transfer protocols. One of the most important attributes of Files.com is its platform independence. Whether you’re using a Windows or Linux system, Files.com ensures a consistent experience through its web interface, desktop app, and command-line access. This makes it ideal for teams operating in diverse environments, providing centralized file management without compatibility issues. Security is another reason Files.com shines.

2. ExaVault (FREE TRIAL)

ExaVault Home Folders

Clean straightforward dashboard for easy file and access managementExaVault is a cloud platform that lets you eradicate the need for a file transfer client by sending a link to recipients instead. You upload files to the system with any standard client and then either store the client there or send an access link to others with timed availability before deletion.

Key Features:

  • Cloud-Based Storage: ExaVault operates on a cloud-based storage system, providing accessibility and scalability for users.

Why do we recommend it?

ExaVault is a very similar service to Files.com. It enables you to set up workflow automation and application orchestration as well as providing cloud file storage with separate accounts for each user. Outsiders are invited to share files through an emailed link and colleagues can collaborate and jointly edit files and add comments.

Think of this system as a replacement for FTP clients because, once the file is on the ExaVault platform, there isn’t any need to transfer them any further. A big advantage of this strategy is that it centralizes file storage for multi-site or virtual offices and enables file sharing and distribution among teams. This is a system that you would use to support home-based workers.

ExaVault Link Sharing

Share a link to your file via an email for ease of use

Who is it recommended for?

This system is great for distributed teams and companies that operate a virtual office strategy. You can remove the need for in-house file servers with this tool if all of your employees work from home or are always out on-site.

Pros:

  • Managed File Transfer Workflows: Users can create managed file transfer workflows for process automation, streamlining file transfers and improving efficiency.
  • Access Rights Control: Options to revoke or set timeouts for access rights provide added security, especially for sensitive or time-sensitive data.
  • Data Protection Compliance: Central activity logging supports data protection standards compliance, ensuring adherence to regulatory requirements

Cons:

  • Pricing: The pricing structure for ExaVault is not publicly available and requires users to request pricing information, potentially leading to uncertainty regarding costs.

This software was my go-to SFTP and SCP software for quite some time. The CLI (Command Line Interface), PuTTY integrations, and large user base all help extend how much you can get out of this free software.

Who is it recommended for?

WinSCP is a worthwhile tool for any system administrator. The tool is only available for windows, so if you only run Macs or Linux machines, you will need to look elsewhere for a secure file transfer utility.

Pros:

  • Simple Interface: WinSCP features a user-friendly and straightforward interface, making it easy to use even for beginners in secure file transfers.
  • Open-Source: Being an open-source application, WinSCP offers transparency and the ability for users to inspect and modify the codebase according to their needs.

Cons:

  • Windows Compatibility Only: WinSCP is limited to the Windows operating system, which may be a drawback for users requiring cross-platform compatibility.

You can download WinSCP here.

4. SolarWinds Solar-PuTTY

SolarWinds Solar-PuTTY

SolarWinds recently released Solar-PuTTY, a software that takes the popular PuTTY tool and builds it out a bit further to add a more modern GUI and a variety of additional features. I’ll be covering this software in more detail in a piece soon, so we’ll focus on the FTP, SCP, and SFTP features of Solar-PuTTY here.

Key Features:

  • Based on PuTTY: SolarWinds Solar-PuTTY is based on the original PuTTY, a widely used SSH and Telnet client.
  • Easy-to-Use Interface: It features an intuitive and user-friendly interface, making it accessible for network professionals.

SCP is also available.

In short, this portable software is a useful tool for ad-hoc file transfers. It’s free, supports drag-and-drop transfers, logging, storing credentials and sessions, and more. I’ve been using Solar-PuTTY in place of PuTTY as my go-to SSH client for a bit, and the SFTP client has been a nice plus.

While I can’t say I like Solar-PuTTY’s interface more than WinSCP for SFTP/SCP transfers, the fact it is also an SSH client is a big plus. That and the storing of sessions makes it easy enough for me to use Solar-PuTTY regularly.

Who is it recommended for?

Solar-PuTTY is a nice update of the old PuTTY system that is easy to use and a real time saver for system administrators. This tool is free to use and useful for any technician that works from a Windows PC.

  • Cost-Effective: Being a free tool, SolarWinds Solar-PuTTY provides valuable features without requiring a financial investment.

Cons:

  • Professional-Oriented Design: While the interface is user-friendly, Solar-PuTTY is designed primarily for network professionals and may not be as suitable for home users or beginners.

6. FileZilla

FileZilla Site Manager

I like the ease of use and the large file send capacity

FileZilla is a free and open-source (released under the GNU General Public License) FTP client software for Windows, Mac OS X, and Linux.

FileZilla is a popular and mature FTP client software that supports FTP, FTPS, and SFTP. The “pro” version of FileZilla adds support for WebDAV and a variety of cloud storage providers (Amazon S3, Dropbox, etc.) as well. FileZilla supports drag and drop, transfer of files greater than 4GB, configurable transfer speed limits, and more.

Fillezilla SFTP

Why do we recommend it?

FileZilla will run on Macs, and Linux machines as well as Windows PCs. the tool offers a choice between SFTP and FTPS and it will store access credentials for return connections. The standard version is free to use and a paid version is available for transfers to cloud platforms.

One of the most significant benefits of FileZilla is its broad user community. If you are stuck trying to figure things out on your own and run into issues, this could be a handy free resource. You can download the FileZilla client for free here.

One of the criticisms of FileZilla has been that it tries to add “bloatware” during the install. While this is understandable given they are trying to make some money, it can be off-putting to many users.

Who is it recommended for?

FileZilla is a good choice for any system administrator. Technicians who only work with Macs and Linux machines will be glad to have this utility instead of WinSCP.

Pros:

  • Free and Open-Source: Being free and open-source, FileZilla is a cost-effective option for individuals and organizations with budget constraints.
  • Cross-Platform Compatibility: It is compatible with Windows, Linux, and Mac operating systems, offering flexibility and accessibility across different platforms.
  • Drag-and-Drop Transfers: FileZilla’s drag-and-drop interface makes it user-friendly, particularly suitable for non-technical users who prefer intuitive file transfer methods.

Cons:

  • Potential Bloatware: Some users may encounter bloatware or additional software bundled with the FileZilla installation, which can be a downside for those seeking a clean installation.
  • Lack of Paid Support: FileZilla relies on community-driven support for bug fixes and updates, lacking dedicated paid support options for users who may require more extensive assistance.

At the least, FileZilla gives you the ability to opt-out of the additional software during the install process. It is something you should be cognizant of before blindly clicking through the install of this tool.

7. CyberDuck

Cyberduck

I find it pairs well with common cloud-based storage providers

CyberDuck is a free and open-source remote file transfer client with support for a wide variety of protocols and cloud storage providers. CyberDuck is a solid alternative for users looking to move away from FileZilla as it offers many of the same features and the ability to import bookmarks from FileZilla (as well as several other apps).

Key Features:

  • Compatibility with Cloud Storage: CyberDuck is compatible with various cloud storage services, allowing users to manage files across different platforms.
  • FTPS and SFTP Support: It supports secure file transfer protocols like FTP/S and SFTP, ensuring data security during transmission.

Integrations to cloud platforms, including Azure, AWS, Backblaze, OneDrive, and Google Drive make uploads easy – this is a feature that users of FileZilla have to pay for.

While CyberDuck has a respectable feature set when it comes to protocol support (FTP, FTPS, SFTP, and WebDAV are all supported) and security, what really stood out to me was its support for a wide variety of cloud storage providers. CyberDuck boasts support for Amazon S3, OpenStack Swift, Backblaze B2, Microsoft Azure & OneDrive, Google Drive, DRACOON, and Dropbox.

Cyberduck SFTP

Who is it recommended for?

CyberDuck is a handy free utility that system administrators should have available, especially if their infrastructure includes both on-site and cloud platforms. The system provides SFTP and FTPS.

  • Encrypted Credential Storage: It offers encrypted credential storage, enhancing security by protecting user credentials.

Cons:

  • Drag and Drop Features: Some users may find that the drag-and-drop features in CyberDuck could be improved for smoother file management.
  • User Interface: The default view and user interface of CyberDuck could be made more user-friendly to enhance usability, especially for new users.

The GUI doesn’t default to a drag-and-drop “two-pane” view like many other clients, but I had no problem dragging from Windows Explorer into the CyberDuck GUI. You can download CyberDuck for Windows or Mac directly from its home page here.

8. MonstaFTP

MonstaFTP

My network admin audience should have all the necessary privileges to access this browser based FTP client

MonstaFTP is a novel approach to FTP. It is a PHP and Javascript-based app that runs on a website and effectively makes your browser the FTP client. While this means that the network server administrator would need to set it up and therefore it isn’t the ideal solution for everyone, we thought the idea was worth noting here as well.

Key Features:

  • Browser-Based: MonstaFTP operates entirely in a web browser, eliminating the need for software installation.
  • Support for Multiple Protocols: It supports FTP, SFTP, FTPS, and SCP, providing flexibility in file transfer options.
  • Free Version: A free version of MonstaFTP is available, making it accessible to users without cost.

Why do we recommend it?

MonstaFTP provides secure file transfers and it is implemented as a PHP function that can be integrated into websites. The tool’s form can be branded. This system is available in free and paid versions and it offers SCP, SFTP, and FTP for secure transfers as well as FTP.

MonstaFTP supports FTP, FTPS, SFTP, and SCP. It enables users to upload .zip files and extract them on the server-side, edit files on-screen, customize the user interface, and rebrand the software. This could be an interesting solution if you are an administrator looking to make life easier for your users. As opposed to making them pick a client on their own (which may come with a non-trivial support burden for you), you can provide the client on the server-side. The ability to drag and drop from Windows Explorer is a nice plus as well.

MonstaFTP SFTP

Who is it recommended for?

MonstaFTP can only be used once it has been integrated into a Web page. Therefore, it isn’t available off the shelf for use by office workers or administrators. It cloud be added to an intranet page by businesses that want to make a file transfer utility available to their staff.

Pros:

  • Web-Based Operation: Since MonstaFTP runs in a web browser, users can access it from any device with internet access, making it convenient and versatile.
  • Multiple Protocol Support: It supports various file transfer protocols like FTP, SFTP, and SCP, catering to different security and compatibility needs.
  • On-Screen Editing: MonstaFTP allows on-screen editing, enhancing workflow efficiency by enabling users to make changes directly during file transfers.
  • Rebranding Option: The software can be rebranded, making it a potential choice for MSPs looking to offer customized file transfer services.

Cons:

  • No Downloadable Version: As MonstaFTP operates solely through a web interface, there is no downloadable version available for offline use.
  • Browser Vulnerabilities: Being web-based, MonstaFTP is susceptible to browser exploits if the user’s machine is infected with malware, potentially posing security risks.

There are lite (free), business ($49/year), and host ($149/year) versions of MonstaFTP available as of this writing. You can download the free version or buy a license here. You can also add a free 45 day Host Edition trial when you download the lite version. If you would like to take it for a test drive before installing, you can demo MonstaFTP from your browser here.

9. Bitvise SSH Client

Bitvise SSH Client

Useful, but skip to the next review if you need to send multiple files simultaneously

The Bitvise SSH Client is a free tool and can be paired with the paid Bitvise SSH Server, but it is will work with any server that has SSH or SFTP capabilities. A nice feature of this package is that you get a secure remote terminal system as well as an SFTP client.

Unlike many free IT tools, Bitvise SSH Client is regularly updated. It is compatible with Windows 11 and Windows Server 2022, which shows that the utility’s creators are keeping an eye on developments in the world of IT. The Bitvise system can be integrated into workflow automation via a scripting system because transfers and remote sessions can also be launched from the command line.

The SFTP utility in Bitvise SSH Client is straightforward and contains few surprises. It doesn’t include any multi-thread options or simultaneous transfers to multiple remote sites. However, it does provide a continuity mechanism that enables interrupted transfers to be resumed when a broken connection is re-established. It is also possible to pause and resume transfers.

The SFTP client is presented as a graphical user interface for Windows and it provides standard features, such as side-by-side local and remote directory listing, click-to-change directory movements, and drag-and-drop file movement commands.

Alternatively: Use the built-in Linux, Windows, and macOS CLI programs

If you can’t, or don’t want to, install any programs you may be able to get away with the various command-line options available on most modern operating systems. Here we’ll provide a quick overview of what’s available on Linux, macOS, and Windows.

For those of you comfortable with the Linux CLI, the built-in SFTP and FTP programs may be all you need. If you are comfortable with using SSH from a command line, using these two programs should be easy enough. For a primer on SFTP from the Linux CLI, check out this Digital Ocean article.

Given that they are both *nix-based operating systems, the macOS SFTP command-line program is similar to the Linux SFTP program described above. However, beginning with High Sierra, macOS dropped support for plaintext FTP from the command line (check out this Apple discussion for details). If you need CLI plaintext FTP support and are running a newer macOS, installing the open-source inetutils might be the way to go. The command brew install inetutils can be used to install the inetutils suite of tools. Note: inetutils includes a variety of client and server programs, many of which transfer data in plaintext. Consider using an encrypted file transfer method like SFTP or FTPS instead of installing inetutils.

Windows also offers a built-in command-line FTP program you can invoke simply by typing “ftp” at the command prompt. However, there is no such program for SFTP, so you’ll need to install a third-party client tool like PSFTP (from the creators of Putty).

Honorable mentions

There were two client software products that just missed making our list (if you think we should reconsider, let us know in the Comments section below).

Classic FTP is software you may want to consider if you are a Windows Home user who only needs support for FTP and FTPS (SFTP is not supported). Given the context of our list, we decided to leave it off as the freeware version is only available for non-commercial use.

FireFTP is a popular browser that we would have added to our list had Firefox not dropped support. Now FireFTP recommends users leverage the less popular WaterFox browser, so we decided to leave them off. The reasoning behind this decision was not that FireFTP or WaterFox is subpar, just that changing browsers just for FTP support might not be ideal given the availability of alternatives.

Need-to-know: FTP, FTPS, SFTP, SCP & Fish clients

What is FTP?

The File Transfer Protocol (FTP) is, as the name suggests, a client-server protocol used for transferring files between computers on a network. FTP uses Transmission Control Protocol (TCP) port numbers 20 & 21 by default. FTP enables users to download, upload, view, rename, delete files, and more.

FTP is a relatively old protocol. While this helps explain some of the oddities like using two ports, it also speaks to the maturity of the protocol. The original standard for FTP, RFC 114, was published in 1971. The current standard, RFC 959, was published in 1985.

Connection Modes: Active vs Passive FTP

There are two discrete FTP connection modes: active FTP and passive FTP. With active FTP mode, port 21 is used to send the control commands that dictate what happens during an FTP session. Port 20 is used for the actual transfer of data. In passive FTP mode, an arbitrary port higher than 1023 is used in place of port 20. Slacksite takes an excellent deep dive into the topic of active vs passive FTP if you’re interested in learning more.

Transfer Modes: Binary vs ASCII

There are also two different FTP transfer modes: binary and ASCII.

For text files (i.e. a file that is human-readable with a program like Notepad, vi, or nano), ASCII is recommended. This is because ASCII transfer mode supports character translation between different systems (e.g. conversion of end of line characters). This can be important when transferring scripts.

For non-text files, like JPEG images, binary transfer mode is recommended. This is because the character translation in ASCII mode can corrupt non-text files. If you have ever transferred an image between two computers and it wasn’t viewable on the receiving machine, the root cause may have been the ASCII transfer mode use.

If this gets a little hard to keep up with, don’t worry too much. In most cases, you can just use binary transfer mode and not think about it further.

FTP & SFTP Clients FAQs

Is FTP secure?

In a word, no. FTP sends files and credentials across the network in cleartext. That means data sent using FTP is NOT encrypted.

For this reason, it is often better to use an encrypted transfer method like FTPS (FTP Secure) or SFTP (SSH File Transfer Protocol).

What is FTPS?

FTPS is effectively FTP with support for TLS (Transport Layer Security) encryption. In the past, FTPS also used SSL (Secure Sockets Layer). SSL is much less common with FTPS today due to a variety of security issues. Using FTPS instead of standard FTP enables you to get the functionality of FTP, plus the benefits of encryption and certificates.

There are two main types of FTPS connections, implicit and explicit. Servers using implicit FTP listen for connections on port 990 instead of port 21. As mentioned by FileZilla, implicit FTPS is a legacy protocol at this point. This means you won’t see implicit FTPS used as much as explicit FTPS these days. Explicit FTPS (a.k.a. FTPES) uses port 21 like standard FTP and enables the client to call for an encrypted connection explicitly.

What is SFTP?

SFTP, rather counterintuitively, is NOT just an encrypted version of the FTP protocol. While it serves the same purpose of transferring and managing files, under the hood SFTP is significantly different from FTP and FTPS. Many of these differences stem from the fact that SFTP sits atop the SSH (Secure Shell) protocol.

One significant difference is the usage of ports. As opposed to using two discrete ports, SFTP uses just one. By default, this port is TCP port 22 (the default SSH port). Using the SSH port has the added benefit of making SFTP generally more “firewall-friendly” and less likely to be blocked by default.

Additionally, SFTP enables users to benefit from the use of SSH private keys. If you are unfamiliar with the benefits of SSH private keys and asymmetric cryptography, check out this article from Digital Ocean. In short, SSH private keys add an additional layer of security to the authentication process.

Personally, I prefer SFTP to FTP/FTPS/FTPES, but there are use case arguments for both. The near-ubiquity of SFTP on most Linux/Unix servers, firewall benefits of using the single port, and the security benefits of leveraging SSH are the reasons for my preference. However, some may make an argument for FTPS based on the specifics of a given environment (e.g. if there are already FTP servers running), support for X.509 certificates, or support for server to server file transfers.

What about SCP and FISH?

If you are researching file transfer protocols, you may have come across SCP (Secure Copy) and FISH (Files Transferred Over Shell Protocol). These two protocols are similar to SFTP in that they use SSH to facilitate the connection (FISH can also use rsh).

SCP is a popular solution that can prove helpful if you simply need to transfer files. However, if you need to list remote directories, create new directories, remove files, or do other administrative tasks, you’ll need to use SFTP or FTP.

FISH is not as widely-used as SCP or SFTP, but may be helpful where resources and the ability to install software on the server-side is highly limited.

Where are FTP & SFTP used?

You can find FTP and SFTP used in a wide variety of use cases. Anytime you need to transfer files from computer A to computer B or manage files on a remote system is a potential use case for SFTP and FTP. Some of the most popular use cases include:

Uploading files to Content Management Systems (CMS) like WordPress.

*nix server administration. SFTP is ‘the’ popular choice here.

File sharing. Using a protocol like SFTP may be particularly useful to meet compliance requirements (e.g. for SOX, HIPPA, or FIPS).

Firmware upgrades. Many devices support firmware upgrades via FTP or SFTP.
