What is OpenText Core DNS Protection?

OpenText Core DNS Protection is engineered to counter one of today’s most exploited attack surfaces: DNS traffic. Acting as a dedicated DNS firewall, it continuously inspects every DNS query and blocks malicious or suspicious destinations before they can be reached. This protection extends across malware, phishing infrastructure, ransomware command centers, and stealthy DNS-tunneling techniques designed to evade traditional defenses. The system identifies DNS leaks, enforces encrypted DNS policies, and dynamically detects unauthorized DNS servers attempting to circumvent security controls. Hybrid and remote workers benefit from consistent protection because the agent filters DNS traffic regardless of the network they connect to. Administrators can centrally enforce DNS policies and analyze activity through comprehensive logs and analytics dashboards that reveal hidden risks. With cloud-native deployment, organizations gain immediate, scalable DNS security without needing complex configurations. Automated real-time threat response mitigates risks instantly, reducing reliance on manual intervention. Customers report significant reductions in support issues as DNS misconfigurations and threats are resolved proactively. Together, these capabilities give organizations precise visibility, strong control, and powerful protection across every DNS request flowing through their environment.

What is Control D?

Control D is a versatile DNS filtering and traffic redirection service that utilizes advanced Secure DNS protocols such as DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC, while also accommodating traditional DNS. With Control D, users can effectively eliminate harmful threats, restrict various types of undesirable content across the network—including advertisements, trackers, IoT data, adult material, social media, and more—while also redirecting traffic through transparent proxies and monitoring network activities and usage patterns at a client-specific level. Consider it your own personalized Authoritative DNS resolver for the entire Internet, providing you with detailed control over which domains are allowed to be resolved, redirected, or blocked. This capability not only enhances security but also empowers users to tailor their online experience according to their preferences.
