Perfect for home, which looks at safety and small companies. Already in the base provides great opportunities for networking and VPN settings. To the device it is possible to buy additional modules that but rather appreciate the customers who are looking for comprehensive security.
A wide choice of configuration, performance and throughput Support A variety of settings - it may be too complicated for someone. It should have at least a basic knowledge of networking, LAN and WAN
