Network security devices are generally applied between two or more networks, such as between the internal network and the external network. The application programs in the network security device will analyze the network packets passing through it to determine whether there is a threat. After processing, the packets will be forwarded according to certain routing rules. However, if this network security device malfunctions, such as power failure or crash, then all network segments connected to this device will lose contact with each other. At this time, if it is required that all networks still need to be connected, then Bypass must come into play.

During the software testing process, when bypass code appears and uncompletely developed software is being tested, some functions are not yet completed and errors will occur. Through bypass code, these errors can be ignored and skipped, so that the testing of other functions can continue.

• Support intelligent switching of various gateway devices (such as firewalls, IDP, UTM, intrusion prevention system IPS, spam gateway, anti-virus gateway, dedicated DDoS devices, dedicated logical isolation devices in various fields, etc.), and provide standard development interfaces (supporting various system devices such as Windows/Linux/BSD/Unix/Solaries);
• Pure hardware switching with short switching time and no impact on data transmission rate;
• Customizable switching critical selection points;
• Support multiple switching methods: automatic switching or manual software switching;
• Ensure the security of its own equipment and automatic bypass in case of failure;
• Indicator light and sound switching alarm notification function;
• Support multi-interface automatic switching;
• Transparent mode, no IP address required for itself;
• Plug and play without affecting the network structure;
• 1U standard industrial-grade chassis design, with mean time between failures (MTBF) greater than 40,000 hours;
• Can be applied in various stages such as gateway device maintenance, upgrade, program debugging, and equipment testing to avoid short-term network interruptions;
• Support custom single-mode or multi-mode fiber optic interfaces.
