WS_FTP

WS_FTP (also owned by the massive enterprise titan Progress Software, operating alongside MOVEit) is one of the oldest, most legendary, and fiercely trusted commercial FTP platforms in the world. First released in 1993, it is the absolute bedrock of file transfer for thousands of IT departments. While MOVEit is for massive enterprise MFT automation, WS_FTP provides incredibly reliable, highly secure Client and Server software for mid-market IT operations. The core superpower of WS_FTP is its "Bulletproof Security and Legacy Reliability." It is heavily favored by IT administrators who need a highly stable, FIPS 140-2 validated SFTP client to connect to mission-critical legacy mainframes or secure Linux servers. It features deep 256-bit AES encryption, integrated OpenPGP file encryption, and SSH key management, ensuring that data is protected both during transfer and while resting on the hard drive. Furthermore, WS_FTP Professional (the client application) offers highly robust synchronization utilities, automated backup scheduling, and email notifications upon transfer completion. It handles massive directories and massive files with an unshakeable connection engine that seamlessly resumes dropped transfers. For IT professionals seeking a commercially supported, incredibly secure, and battle-tested FTP utility, WS_FTP remains a formidable standard.
