Serv-U is a powerful, easy-to-use, award-winning FTP server created by Rob Beckers. An FTP server uses the FTP protocol to share files across the Internet.

Serv-U features an open architecture that makes it very easy to extend, monitor, and change the server behavior with external DLLs.
Regardless of the purpose behind your FTP server, everyone will benefit from the numerous security features Serv-U incorporates.
When you're using Serv-U, you'll be able to: 
· Restrict directory & file rights
· Deny or allow IP addresses
· Monitor user actions in real-time
· Log all commands from users; Best of all, these security settings are customizable for each user and group.
Whether your corporation needs an FTP server for hundreds of users or you need a way to share files with some friends, Serv-U is the file sharing solution that can grow with your needs for a long time to come.

SSL / TLS Support:
· Support high-grade 128-bit Secure Socket Layer (SSL) encrypted communications using FTPS and HTTPS. When using FTPS or HTTPS, file transfers and remote administration sessions are secured.
Trusted Certificate:
· Create a certificate and have it signed by a trusted authority to positively identify your server as genuine to your end-users.
SFTP over SSH2:
· Securely transfer files using the firewall friendly SFTP protocol. Create a 4096-bit private key and customize the list of available ciphers and MACs for maximum security.
Strong Passwords:
· Enforce a strong password policy that sets the minimum length and complexity requirements for account passwords.
S/KEY Password Encryption:
· Secure the FTP authentication process over unencrypted FTP connections using S/KEY One Time Passwords with compatible FTP clients.
Powerful IP Access Rules:
· Restrict access to the entire File Server, specific domains, or even individual user accounts with powerful IP access rules. IP access rules can define acceptable or unacceptable IP addresses, ranges, and reverse DNS masks. You can even specify a domain name that allows dynamic DNS to grant access for mobile users.
Highly Configurable Access Rules:
· Grant access only to approved resources using advanced directory access rules. Use virtual paths to map external locations to a user's accessible locations, restrict access to individual files, folders, and file types, and much more.
Remote Web Based Administration:
· Administer your File Server from anywhere in the world using your Web browser. Connect using HTTPS to encrypt your remote administration session.
ODBC for Easier Administration and User Management:
· Serv-U File Server allows you to store your user accounts in an ODBC database for ease of management.
Multiple Authentication Sources:
· Supplement the local Serv-U account database with an external database through ODBC, the local Windows user database, or integrate with an Active Domain server - all on the same domain.
Granular Bandwidth Controls:
· Restrict upload and download bandwidth for the entire server, each domain, all group members as a whole, or each individual user. You can even apply different bandwidth restrictions during different times of the day or days of the week.
File Integrity Checking:
· Ensure that transmitted data has not been tampered with or incorrectly transmitted using an XCRC checksum.
Customized FTP Settings:
· Disable individual FTP commands, configure advanced FTP command options, and customize the response message for every FTP command - only with Serv-U.
Automated Account Maintenance:
· Configure individual user accounts to be deleted or disabled on a specific date.
Full Group Support:
· Easily manage hundreds of users with full group support. Configure home directories, directory access rules, IP access rules, and much more at the group level. Users can inherit their settings through group memberships for quick configuration and easy maintenance. You can even override individual settings on a per user basis.
Support for 13 Languages:
· When end-users (or remote administrators) login to Serv-U from their Web browser, they can choose to use any of the 13 supported languages.
Web Client:
· Serv-U offers a familiar and easy-to-use transfer client to all your end-users with the built-in Web Client accessible from their web browser.
Media Player:
· Play audio and video files in the Web Client using the built in Media Player. Also, use the Playlist feature to turn an entire directory into a streaming playlist of your favorite audio files.
Multiple Protocols Per Domain:
· Adding additional protocol support to a domain is as easy as choosing the protocol and selecting an available port. Making a domain accessible through multiple protocols gives users flexibility in how they connect.
Virtual Hosts:
· Easily add another domain to the same IP address and port combination using Virtual Hosts. FTP clients select the proper host before logging in with a simple command. HTTP clients are automatically directed to the appropriate host based upon their connection request.
Real Time Information:
· View server and domain activity in real-time with detailed statistics and history on each session.
User and Group Templates:
· Create a template for new user accounts and groups for quick creation. The template initializes all settings and rules for newly created users and groups.
