OpenText™ Core DNS Protection
Solution snapshot
Block malicious domains, ransomware, and phishing attacks before a connection is made.
Stop data exfiltration by cutting off access to command-and-control servers at the DNS level.
Secure remote and hybrid workers on any network without disrupting productivity.
Control encrypted DNS traffic (DoH/DoT) and ensure requests route through trusted resolvers.
Deploy quickly across endpoints and operating systems with no impact on user experience.
Why DNS protection is critical
The Domain Name System (DNS) is the backbone of internet connectivity and a growing target for cyberattacks. With hybrid work expanding and encrypted DNS (DoH/DoT) becoming standard, attackers exploit DNS resolution to bypass defenses, steal sensitive information, and communicate with malicious domains. Without full visibility and control over your DNS infrastructure, your organization is vulnerable to malware, cyber threats, and compliance risks.
Safeguard web use with DNS filtering
OpenText Core DNS Protection is a cloud-native DNS security solution that filters every DNS request—from browsers, apps, or background processes—to block access to malicious sites and prevent data exfiltration.
It secures endpoints across all operating systems, enforces policies in real time, and ensures that encrypted DNS traffic is resolved only by trusted sources.
Core benefits of DNS protection
Most threats don't announce themselves. OpenText Core DNS protection stops them at the earliest possible point, before they ever reach your users, devices, or data.
Block malicious domains to prevent malware, ransomware, and phishing attacks.
Stop data exfiltration by cutting off access to command-and-control servers.
Gain full visibility to all DNS activity with comprehensive logs
Centralized policy enforcement to filter all DNS requests.
Control DoH/DoT connections and inspect encrypted DNS traffic.
Hybrid and remote workforce protection on any network.
Advanced DNS protection features
Attackers exploit DNS because most organizations can't see what's happening at that level. Core DNS Protection gives you complete visibility and control over every DNS request, from any device, on any network.
Agent-level awareness stops unauthorized DNS resolution at the process level.
Dynamic detection of unauthorized authoritative DNS servers.
Filter device DNS requests in real time for hybrid work environments.
Logs DNS responses for visibility, investigation, and compliance reporting.
Continuous monitoring to enforce security measures across your DNS infrastructure.
Continuous monitoring to enforce security measures across your DNS infrastructure.
Quick deployment across endpoints with no impact to the user experience.
Uses trusted, encrypted DNS resolvers to safeguard sensitive information.
How OpenText DNS Protection blocks malicious activity
OpenText Core DNS Protection acts as a DNS firewall, monitoring all DNS traffic for signs of malicious activity. It filters requests against known DNS servers, dynamically identifies unknown servers, and blocks harmful queries in real time.
Detailed analytics and reporting provide insights into DNS traffic, identify vulnerabilities, and protect your organization from malicious actors.

FAQ
Protective DNS filtering is a DNS security service that analyzes all DNS requests, comparing them against threat intelligence feeds to block access to malicious domains before a connection is made. By filtering DNS traffic and logging DNS responses for visibility and investigation, solutions like OpenText DNS Protection can stop multiple stages of cyberattacks—including phishing, malware delivery, and lateral movement—and even prevent threats from reaching your endpoints, users, or DNS infrastructure.
