SFTPGo is a managed file transfer platform for secure file exchange, storage, and workflow automation. It supports SFTP, FTPS, WebDAV, and browser access through a WebClient. Storage can use local filesystems, S3-compatible services, Azure Blob, Google Cloud Storage, or other SFTP servers. Scheduled and event-driven workflows can notify users, move files between storage backends, ingest IMAP attachments, or use the REST API and Terraform provider. Authentication options include passwords, public keys, multi-step authentication, two-factor authentication, and OpenID Connect single sign-on. Listed protections include encryption at rest and in transit, brute-force auto-blocking, granular access controls, and audit logs. File and folder links can have password or email authentication, expiry dates, and download limits. Integrations include Collabora Online, ICAP, LDAP, Active Directory, and Entra ID. The Open Source edition is a production-ready community edition under AGPLv3. SaaS plans start at €50 a month, with a 10-day trial; Tiny and Small are not suited to installations with many simultaneous connections. Enterprise deployment supports Linux, Windows, Docker, or Kubernetes.
