DNS Firewall roaming client is a DNS based security solution that protects your iOS device from malicious, unauthorized, or inappropriate web content by analyzing DNS queries and blocking malicious domains in real-time. The roaming client is a standalone application and secures your DNS traffic whether you are connected to your corporate network, public Wi-Fi or any other network globally.
For company-owned devices in supervised mode, administrators can perform bulk deployment using any MDM solution. Alternatively for BYOD devices, administrators can share a one-time authentication code for devices to start using DNS Firewall.
