The purpose of Bypass Switch is to prevent security equipment in inline transparent mode, such as NGFW, IPS, WAF, DDoS, SSL, and DPI, from being unstable and crashing due to software instability. , network disconnection caused by power outages and maintenance. Even if an HA architecture has been deployed, there is still the problem of being unable to automatically switch lines. In order to avoid being invaded by hackers or worms, enterprises need to deeply inspect each packet. , only after confirming that it is safe can the packet be allowed to pass. This complicated task consumes a lot of CPU performance of the device. Most of the reasons for enterprise network disconnection are the crash of the security equipment software or human operation factors. It is not a power outage problem, and these can be solved by deploying a bypass switch. A disconnection causes an immediate disaster for the enterprise, and even a loss of revenue. The function of the bypass switch can eliminate the risk of this disconnection. drop to lowest.

Silicom IBS (1G), IS40 (10/40G), IS100 (100G) Bypass Switch, all belong to the highest level of protection, with active and passive bypass capabilities, which can protect the network and prevent surveillance Network interruption due to equipment maintenance, crash, or power outage. In addition to sending monitoring heartbeat packets (Heartbeat) and monitoring the security host for bypass switching, Silicom's biggest advantage is that it also monitors the health status of the bypass switch itself, and can perform bypass even if it crashes or loses power. Switchover without becoming a point of failure in the network.

It is generally believed that the most common causes of network disconnection for Inline security equipment are: software instability, crashes, incorrect rule settings, attacks, etc., or the traffic processing speed is very slow, but the network is not disconnected. The ""half-dead"" state causes users to be unable to access the Internet. Even if an HA architecture is used, when this situation occurs, it is still necessary to manually unplug the cable or cut off the power to completely disconnect the Active line before HA routing can be started. The expected built-in bypass network card cannot achieve the expected protection effect in the event of a crash, and still causes network Downn Time. The problem of disconnection still needs to be dealt with manually. Therefore, more and more managers are beginning to pay attention to the difference in disconnection protection levels. , and are willing to accept a more effective Bypass Switch disconnection protection solution.
