Company Overview
ISPConfig is an open-source Linux hosting control panel originally created in 2005 by Till Brehm, Ingo Riedel, and other contributors based in Germany. Released under the BSD license, ISPConfig provides a web-based graphical interface for server administrators and hosting providers, supporting both Apache and NGINX web servers with multi-server management capabilities.
ISPConfig covers the full spectrum of web hosting operations: virtual host management, DNS zone administration, email server setup (Postfix + Dovecot), FTP account management, database administration, and SSL certificate configuration. Its multi-server architecture allows web, DNS, mail, and database services to be deployed on separate servers for load balancing and horizontal scaling.
