IceWarp

IceWarp is a Czech IT company offering a comprehensive solution for corporate communication. Since its founding in 1998, the company has expanded its operations worldwide, including offices in the USA, Germany, Russia, and India. Today, IceWarp serves over 50,000 business clients and actively competes with giants like Microsoft and Google.

The company's main product is the IceWarp Mail Server — a powerful mail and groupware server supporting standard protocols (SMTP, IMAP, POP3), Outlook synchronization (via ActiveSync), as well as calendars, chats, collaborative document editing, VoIP, and antivirus protection. The solution is available both in the cloud and for on-premise deployment, making it a flexible choice for companies with different IT infrastructures.

Complementing the mail server is the IceWarp Collaboration Hub — an integrated teamwork platform that combines email, video conferencing, chat, and document management. Its web interface, desktop clients, and mobile apps allow employees to stay connected from anywhere in the world. IceWarp also actively develops its mobile platforms — Android and iOS apps are regularly updated, providing access to TeamChat, Notes, and video conferencing for up to 1,000 participants.

The platform has gained industry recognition and has won numerous awards, including Red Herring Top 100, TMCnet Product of the Year, and CIO Choice. IceWarp also supports open-source development and is one of the sponsors of LibreOffice Online, enabling real-time collaboration on documents via a web browser.

IceWarp continuously updates its solutions, adding AI-powered features, improved interfaces, and expanded video conferencing capabilities. The latest stable version of the server was released in February 2025, with the beta version 14.2.0 following in April.

Thanks to its functionality, security, and deployment flexibility, IceWarp is an excellent choice for organizations looking for a corporate communication platform independent of Microsoft and Google.
