With the increasing availability of wireless technology, small offices and SMBs are finding that WLAN deployment can allow them to increase the overall efficiency of their business but they still remain on the sideline. The most important reason is that they are concerned about the exposure of their sensitive corporate information over the WLAN network. Billions BiGuard S100N is the perfect solutions for SMBs that need a flexible, secure wired and wireless connection, and always-on connectivity to the corporate resources. Integrated with portal-based wireless NAC (Network Access Control), the BiGuard S100N enables workers or visitors to roam freely, securely and seamlessly between subnets in an office building, or between different network types LAN, WLAN and WAN without the risk of unauthorized access to the corporate network. By establishing encrypted SSL VPN tunnels, mobile workers can securely access the intranet from any location, such as a branch office, home, or even a public kiosk. Gigabit WAN and LAN ports provide the bandwidth and speed needed for heavy bandwidth consuming applications like video streaming and critical business applications. Energy efficient features such as Smart Power Saving and Wake On LAN (WOL) allow the corporate networks to be more environmentally friendly and to increase cost savings without the compromise of their network performance.
