Secure connectivity to corporate headquarters is essential if your remote employees are going to achieve maximum productivity. Virtual Private Networks (VPNs) add a layer of security to private and public networks, allowing individuals and organizations to send and receive data safely over the Internet. A VPN creates secure connections between computers or networks in different locations back to the corporate network. Organizations rely on a VPN to offer secure connectivity to remote locations and users. Operating at the network layer, a client-based VPN provides users access to the entire network.
