The paper presents the results of studies on the protection of small LANs, in particular its wireless segment, solved using network encryption, corporate encryption methods. It is shown that these methods and tools are rarely used, they require additional equipment, maintenance and are difficult to configure. Custom encryption methods are used more often - they are easy to set up, do not require additional equipment and maintenance, but almost always can be cracked in a relatively short period of time. According to the results of the analysis, the work examines and studies the principle of construction of the principle and the device based on it, which allows to increase the security of networks using custom encryption methods. The principle developed in the work and the device monitors and notifies about network events of the channel and network level, as a result of which all network activity becomes transparent, which significantly increases the network security.
