What Protocols Does Serv-U Support?
Serv-U supports various file transfer protocols to ensure secure and efficient data exchange. These protocols cater to different use cases and security requirements. Below is an in-depth look at the supported protocols. (Protocols with an asterisk are only available with MFT.)
FTP (File Transfer Protocol)
FTP is one of the oldest and most widely used protocols for transferring files over a network. It operates over TCP/IP networks and facilitates straightforward, large-scale file transfers between clients and servers. It uses two separate communication channels: a command channel and a data channel. The command channel sends commands and receives responses, while the data channel transfers files.
FTP is known for its simplicity and high-speed transfers, making it suitable for quickly and efficiently transferring large files. However, FTP transmits data in plain text, making it vulnerable to interception and unauthorized access. This lack of encryption makes FTP unsuitable for transferring sensitive or confidential information.
HTTP (Hypertext Transfer Protocol)
HTTP is the foundational protocol for the World Wide Web. It’s used for transmitting web pages and related files over the internet and for web-based file transfers. It operates over TCP and follows a request-response model. A client, usually a web or mobile browser, sends an HTTP request to a server, which then responds with the requested resource, such as a file or web page.
HTTP, similar to FTP, lacks encryption and therefore transmits data in plain text. This makes HTTP unsuitable for transferring sensitive data.
FTPS (FTP over SSL)
FTPS enhances the traditional FTP protocol by supporting SSL/TLS encryption. This provides a secure way to transfer files, combining FTP’s versatility with robust encryption. It uses SSL/TLS to encrypt the data transfer channels, protecting the confidentiality and integrity of the transferred data. This prevents unauthorized access and data breaches.
FTPS can operate in two modes: explicit and implicit. In explicit mode, the client requests security from an FTP server by sending an AUTH command. If the server accepts, it establishes a secure SSL/TLS channel for the connection. In implicit mode, on the other hand, the client immediately establishes a secure SSL/TLS connection upon connecting to the server.
HTTPS (HTTP over SSL)*
HTTPS is the secure version of HTTP, using SSL/TLS to encrypt data transmitted between a client and server. It’s widely used for secure web communications and file transfers. It encrypts the data transfer channel, ensuring that data remains confidential and protected from eavesdropping and tampering during transmission. HTTPS provides server authentication, helping to ensure that clients connect to legitimate servers through SSL/TLS certificates.
HTTPS helps organizations meet regulatory requirements for data security and privacy by providing encrypted communications and authenticated connections.
SFTP using SSH2 (File Transfer over Secure Shell)*
SFTP is a secure file transfer protocol that runs over the Secure Shell (SSH) protocol. It encrypts both commands and data, preventing password sniffing and man-in-the-middle attacks. This ensures the confidentiality and integrity of data during transfer. Unlike FTPS, which uses one port for its command channel and a second port for its data channel, SFTP uses a single port (port 22), simplifying firewall configurations and reducing the attack surface.
It supports a range of operations beyond file transfer, such as file access, file management, and directory listings, making it a versatile choice for various file-related tasks. It also supports resume and partial file transfers, enhancing its reliability for large file transfers.
SFTP relies on SSH for authentication, including password-based methods, public keys, and other methods, providing flexible and robust authentication options.
Serv-U Downloads
The pricing for Serv-U depends on the product you choose. If you go with FTP, which is simple and easy to use, its price starts at $634. If you want a more robust solution like MFT, its price starts at about $3,827. The Gateway’s pricing starts at $1,272. SolarWinds often tailors pricing based on a detailed assessment of an organization’s file transfer needs, but you can download and start with a fourteen-day free trial for all of its products.
