Highly Secure, Reliable Connectivity for the Small Business Network

The Cisco ® RV042G Dual Gigabit WAN VPN Router delivers highly secure, high-performance, reliable connectivity-to the Internet, other offices, and employees working remotely-from the heart of your small business network. This proven router provides the performance and security you need to help keep your employees, and your business, productive.
The Cisco RV042G enables two connections, either to a single service provider, with load balancing to improve performance, or to different providers to support business continuity. High-capacity virtual private network (VPN) capabilities let multiple offices and dozens of employees access the information they need from anywhere, just as securely as if they were working at your main office.
To further safeguard your network and data, the Cisco RV042G includes business-class security features and optional cloud-based web filtering. Configuration is a snap, using an intuitive, browser-based device manager and setup wizards.
