Cerberus FTP Server vs Waarp R66

Cerberus FTP Server is a secure file transfer server built for Windows. It supports FTP, FTPS, SFTP, SCP, and HTTP/S transfers, with a web client for accessing, editing, and transferring files from desktop or mobile browsers. Administrators can manage accounts through the native user database or Active Directory and LDAP; version 2026.3 adds RADIUS authentication. That version also supports Amazon S3 and Azure Blob Storage as Virtual Directory backends. Security features include SSH, SSL, FIPS 140-3, and TLS 1.3. Event, alert, and synchronization tools support managed file transfer automation, while file access, user, and administrator logs support auditing and reporting. The product is positioned for PCI DSS, HIPAA, FIPS-140-2, and GDPR requirements. Professional and Enterprise editions include unlimited phone and email support during business hours; Enterprise Plus adds 24/7/365 Severity 1 support. Commercial use requires a subscription license, and each license permits installation on one machine. The paid product has no free plan but offers a 25-day trial. Cerberus FTP Server was founded in 2001 and is headquartered in Arlington, Virginia.

Waarp R66 is open-source software for large-scale file transfer with monitoring. It sends and receives files in push or pull mode between identified partners, using database persistence, retries, and restartable transfers. Security features include SSL, optional strong authentication, packet-integrity support, and partner authentication. Rules can trigger file operations or external procedures before transfers, afterward, or when errors occur. Monitoring is available through HTTP and SNMP, with events publishable to a remote HTTP(S) REST API. Documented integrations include FTP, S3 sources and targets, REST APIs, and Java applications. Supported databases listed by the maker are H2, PostgreSQL, and Oracle; MySQL and MariaDB work but are not recommended. Downloads include an all-in-one package with R66, Proxy, and Gateway FTP. Deployment options include Linux, Windows, web, API, self-hosted, and on-premises use. The light client can initiate transfers but lacks database-backed history and restart capability. The maker provides downloads without stating a software price.
