Cyber Shield, a part of OpenVPN Cloud, provides Domain Name System (DNS) content filtering to protect your VPN users from malicious and suspicious websites, even when internet traffic isn’t transported through the VPN. You can choose to simply monitor the number of domain name resolutions that fall into these content categories, or you can take security a step further and enable blocking. DNS-based filtering lets you block domain name resolutions for those websites that fall into undesirable or unsafe categories. Cyber Shield provides data reporting on the number of observed and blocked domain name queries originating from your users. You can drill down and investigate exactly which user-devices generated the DNS requests that were flagged with a particular content category.
