The commonly-used File Transfer Protocol (FTP) requires only a username and password, which isn’t enough to ensure security for sensitive documents. Serv-U file transfer solutions are built to support enhanced security options offering peace of mind. FTP over SSL is an extension adding support for the Secure Sockets Layer (SSL) and its replacement, Transport Layer Security (TLS). Serv-U allows you to use either an existing SSL certificate or create a new certificate. Serv-U supports TLSv1.1 and TLSv1.2, as well as 15 new cipher suites (including Camellia, SEED, SHA, and GCM) to facilitate key exchange, bulk encryption, and message authentication. You can also enable low-security SSL ciphers as needed and can disable SSL or TLS support to ensure compatibility with outdated systems.

Securely share files across your business

Securely share files across your business

Avoid the hassle and security risk of file transfer workarounds. Serv-U users can easily view, upload, and download files from anywhere. Serv-U File Transfer Protocol (FTP)  is the ideal option for project teams or small businesses seeking a secure, easy way to share files over a single server. With Serv-U Managed File Transfer (MFT) server, businesses of all sizes can secure data in transit using SFTP, FTPS, or HTTPS. Both versions offer the security of an FTP SSL client. Additionally, admins can use the wizard-driven interface to create users and groups in order to better control access to the file server.

Easily send files of any size

Easily send files of any size

When teams need to quickly and easily share business files, they tend to run into roadblocks. Common methods like email attachments don’t offer robust security and may impose file size limits. Serv-U FTP over SSL makes file sharing through the web or a mobile interface fast and flexible, even for files over 3GB. Users can easily select and transfer multiple files using the drag-and-drop feature, then view the transfer queue to pause or resume active transfers.

With Serv-U, admins can easily view transfers and configure settings to achieve better control. Avoid bandwidth throttling and stay within storage limits by setting file transfer limits. You can define concurrent session limits, block IP addresses, request reverse DNS, and more. Set the tool to automatically move or delete transferred files and gain granular control over user access and permissions—for instance, you can configure the system to disable or reset usernames and passwords after a specified number of days.

  • What other file transfer features does Serv-U have?
  • What is SSL?

    Secure Sockets Layer (SSL) is a network encryption protocol for transferring data. The SSL handshake between a server and a client uses a “key” or “certificate” to create a secure link (the SSL connection) that transfers encrypted data and files. SSL is an old and widely-known protocol but has been replaced with Transport Layer Security (TLS), a more secure option. Some programs still offer SSL compatibility, even if they also use TLS encryption. SSL meaning can also refer to SSL certificates, which can more properly be called SSL/TLS certificates. These are the certificates informing the client of the server’s identity and initiating a data transfer.

  • How does an FTP SSL client work?

    Essentially, an FTP SSL client allows a user to transfer files by using both the File Transfer Protocol (FTP) and SSL encryption. FTP is a common method for transferring files of any size to or from a web server. While convenient, the FTP doesn’t offer robust security features—it typically requires just a username and password. FTP over SSL (FTPS) is a form of File Transfer Protocol (FTP) supporting the SSL and TLS encryption protocols. FTPS works in a client-server model, with both a control channel and a data channel, and the FTP SSL client verifies the server’s certificate before establishing a connection.

  • Why is FTP over SSL important?

    FTP over SSL (FTPS) is critical because FTP alone doesn’t offer sufficient security. FTPS requires a connection to be authenticated with a user ID and password, along with a public key certificate. The FTP SSL client verifies the trustworthiness of the server’s certificate, which helps protect against man-in-the-middle attacks. Without these security measures in place, bad actors could potentially access sensitive files, users could inadvertently download malware, or third parties could secretly view and alter the communications between client and server.

  • How does Serv-U support FTP SSL?

    Serv-U supports best practice file transfer encryption and security protocols, including FTP SSL. Serv-U supports TLSv1.1 and TLSv1.2, although admins have the option of utilizing low-security SSL ciphers or disabling protocols to ensure backward compatibility. When utilizing FTP SSL, you can either use an existing certificate or create a new one. Serv-U supports 15 new cipher suites that help support successful and secure file transfer over FTP SSL.

  • What other file transfer features does Serv-U have?

    Serv-U offers the robust functionality and features users need to execute effective file transfers. The software supports various secure file transfer protocols, including FTP, FTPS, SFTP, and HTTP/S, and utilizes the FIPS 140-2 cryptographic standard. Serv-U supports two methods for encrypted data transfer: SSL and Secure Shell 2. Serv-U users can easily transfer multiple files and large files (over 3GB), while admins can manage users and groups to maintain file access control. It’s also possible to integrate the program with the Serv-U Gateway to protect data in transit in the demilitarized zone (DMZ).
