Bitvise SSH Server is a Windows server application that provides secure remote access and encrypted file transfer services. It replaces insecure protocols such as Telnet and FTP by using SSH‑based encryption to protect credentials, commands, and transferred data. The server is designed specifically for Windows systems and integrates with native Windows user accounts, groups, and security mechanisms. It supports both interactive terminal sessions and non‑interactive file transfer workflows, making it suitable for administration, automation, and secure data exchange. Bitvise SSH Server emphasizes configurability, strong cryptography, and operational control. It allows administrators to precisely define access rights, authentication methods, filesystem visibility, and bandwidth usage, while remaining manageable through a graphical control panel and scripting interfaces.
