Protection of your network is a mission critical activity. Linksys builds powerful security into every product to keep your wired and wireless networks safe. Linksys Small Business Series systems have advanced firewall, encryption and authentication features to protect you from network threats - threats that can seriously disrupt or damage your business by stealing your valuable data, slowing down your network and interfering with business-critical applications. Linksys systems ensure maximum application availability enabling you to meet corporate governance and business continuance requirements. The Linksys Small Business Series is the affordable, reliable, high quality networking solution that helps you do business smarter. Secure and easy to install and maintain, it's built to grow with your business. As broadband speeds increase most 10/100 gateways do not have the power to support those higher data rates, and thus become the bottleneck in the network. The RVS4000 10/100/1000 4-Port VPN Router works at Gigabit speeds to meet the demands of today's networks. It features Linksys' proven SPI Firewall with an integrated Intrusion Detection and Prevent System (IDS/IPS). Its built-in 4-port full-duplex 10/100/1000 Ethernet switch can connect up four PCs directly, or additional hubs and switches. The QoS features provide consistent voice and video quality throughout your business. In addition, the RVS4000 features a Virtual Private Network (VPN) security engine that creates encrypted "IPSec tunnels" through the Internet. The IPSec VPN tunnels enable remote users from at home, or on the road to easily, and securely connect to the office network through a typical wired or wireless broadband connection. When used with another RVS4000 or other Linksys VPN router, "branch-to-branch" connections can be established allowing users in a remote office to connect to the corporate network.
