Topwalk Security Isolation and Information Exchange System (Topwalk-GAP) (Network Gateway) is China's first product realizing secure information exchange based on network isolation technology. It took the lead in passing the security testing of the Ministry of Public Security and the State Secrets Bureau in 2000. Based on the "2+1" multi-host architecture, it cuts off TCP/IP communication between different network domains, realizing real-time information exchange on the basis of network isolation. It can be widely applied in government agencies, military units and large enterprises.
-
Safe and Reliable Isolation GuaranteeAchieves secure isolation between internal and external networks through dedicated isolation hardware, blocks the transmission of TCP/IP-based network protocols, and the security isolation function is not controlled externally.
-
Supports Mainstream Domestic and Foreign Data AdaptationSupports the adaptation of data such as files, databases, messages and emails; enables the collection and distribution of various types of data.
-
Efficient Secure Transmission MechanismProvides in-depth data content detection and filtering functions for different types of data, and can control the direction of data transmission; supports predefined secure transmission strategies to ensure the security of transmitted data and users' internal networks.
-
Secure Adaptation for Video ServicesSupports fine-grained authorized access management for users and devices of video resources.
The data security isolation hardware ensures the disconnection of the link layer between trusted and untrusted networks through independent control circuits and read-write protection circuits, thereby achieving secure network isolation. Security isolation is realized through hardware to completely block TCP/IP and other network protocols, and data reading and writing are performed through a custom communication mechanism to achieve controlled information exchange.
The security isolation hardware is a key component ensuring secure network isolation. Independently designed by Topwalk with independent intellectual property rights, it is separate from internal and external network units, does not accept external command control, and realizes pure data transfer between internal and external network units.

01
Application ScenariosTopwalk-GAP is widely deployed in scenarios where two or more networks and application systems—regardless of whether they share the same or different security levels—require network isolation and data exchange.
Its primary application scenarios fall into two categories:
1. Policy-Driven Scenarios
To address business requirements, the internal networks of government agencies, large enterprises, and similar organizations need to exchange data with external networks. However, relevant policy mandates and regulatory standards prohibit direct connectivity between internal and external networks. Instead, network isolation and data exchange must be implemented via a dedicated information exchange system.
2. Security-Driven Scenarios
Topwalk GAP is also ideal for use cases involving networks with high security classification requirements.
