Flexible Authentication - Plug in any identity source with a single configuration change:

• Active Directory / LDAP bind.
• JDBC database (H2, MySQL, PostgreSQL, SQL Server).
• SSH public key authentication.
• TOTP multi-factor authentication.

Managed File Lifecycle - Atomic uploads with staging, deduplication, and orphan cleanup ensure every file arrives intact:

• Atomic rename on completion.
• Per-user disk quotas.
• Automatic duplicate handling.
• Orphan cleanup on startup.

Comprehensive Audit - Four parallel audit sinks capture every event for compliance and forensics:

• Database (JDBC).
• Log files (SLF4J / Log4j 2).
• Syslog (RFC 5424) for SIEM.
• Webhooks with HMAC signing.

Browser File Portal - End users upload and download files from any browser — no client software required:

• Folder tree sidebar with collapsible navigation.
• Cut/Copy/Paste with Ctrl+C, Ctrl+X, Ctrl+V.
• Conflict detection and atomic replace.
• Parallel upload (4 concurrent transfers).
• Drag-and-drop folders and files.

Database Filesystem - Store files directly in your SQL database for unified access across all five protocols:

• Hierarchical folders in SQL database.
• Copy-on-write (zero-copy file duplication).
• Works with H2, MySQL, PostgreSQL, SQL Server.
• Same files visible across all protocols.

WebDAV Protocol - Mount your file transfer space as a network drive from any operating system:

• Mount as network drive (Windows, macOS, Linux).
• HTTP Basic Auth over TLS.
• Instant copy/move on database backend.
• Pipeline integration via webhook + HTTP fetch.

Defense in Depth - Multiple layers of protection block threats before they reach your data:

• IP block lists (CIDR notation).
• Connection rate limiting.
• GeoIP country blocking.
• Account lockout policies.

Three Admin Tools - Manage your server your way — command line, desktop GUI, or web console:

• CLI with 61 commands.
• Swing desktop GUI (11 tabs).
• Web admin console (Ext JS).
