Communication Security Deserves a Distinct Experience
|
Self-Hosted Server |
Plug-and-Play Deployment |
Stable Performance in Weak Networks |
|
The server is fully deployed and managed by your organization. With no reliance on public clouds or third-party servers, your communication data remains exclusively under your control. |
Simply connect power and network to complete deployment. No specialized technical expertise required — operational in as little as two minutes. |
Even under adverse network conditions, encrypted voice and video calls maintain stable audio-video synchronization, minimizing lag and interruptions. |
Communication Security Must Withstand Comparison
True security cannot be reduced to a slogan like "we support encryption." It must be demonstrated across every dimension — encryption methodology, key storage, and server deployment.
ComCube embeds security into every critical layer of communication, ensuring that privacy protection is built upon clear, verifiable product mechanisms rather than vague promises.

Communication Security Demands Comprehensive Protection
Server Security
Self-governed server, fully controllable data security
ComCube employs a dedicated communication server, deployed and managed by the user. The server performs only identity authentication and encrypted data forwarding — it does not store chat content, ensuring that communications and data remain firmly in your hands.
End-to-End Encryption
Full-cycle encryption, uncompromising communication security
Messages, files, and all communication content are protected by end-to-end encryption — accessible only to the communicating parties. The server is used solely for identity verification and data forwarding, and cannot access the underlying data.
Encrypted Audio & Video
Cross-border calls, secure communication even in weak networks
Call quality is preserved even under network fluctuations or weak network conditions, delivering a stable and reliable communication experience.
Access Control
Unified member management, granular permission control
Each server is assigned a primary administrator responsible for managing members and access privileges. Administrators can invite, suspend, or remove members, enabling efficient team governance.
Privacy Protection
Timely destruction of sensitive information, minimized leakage risk
Supports Burn After Reading and Burn After Listening, alongside anti-screenshot and screen-recording protection. Sensitive information exists only in the moment — eliminating concerns about data leakage.
Team Collaboration
Isolated communication spaces, built for multi-team operations
Supports member account isolation and seamless switching across multiple servers. Establish independent communication spaces for distinct teams, projects, and business units, enabling clear and efficient division of work.
