OpenText™ Core DNS Protection
Protective DNS service for modern threats
Protect your users and devices on any network with full control of DNS traffic
Why DNS protection matters
DNS is the backbone of internet connectivity, and it's a growing target for cyberattacks. With hybrid work expanding and encrypted DNS becoming standard, attackers use DNS resolution to bypass defenses, steal data, and communicate with malicious servers. Without full visibility and control over DNS traffic, you're vulnerable to malware, data loss, and compliance risks.
DNS-based threats are stealthy, fast-moving, and often invisible to legacy security tools. You need a solution that closes these gaps, whether you're in the office, at home, or on public networks, before attackers exploit them.
Introducing OpenText DNS Protection
OpenText Core DNS Protection is a cloud-native solution that filters every DNS request -- from browsers, app, or background process -- to block threats before they reach your network or device. It stops access to malicious domains, prevents DNS leaks on the fly, and ensures encrypted DNS traffic is resolved only by trusted sources.
Key benefits
Prevent malware by blocking access to malicious domains and servers
Stop data exfiltration by cutting off access to Command and Control servers
Gain full visibility to all DNS activity with comprehensive logs
Deploy in seconds with immediate protection
Secure users and devices on any network, even at home
Features & capabilities
Centralized policy enforcement to filter all DNS requests
Simplified management
Control encrypted DNS (DoH) by inspecting all HTTPS connections
Agent-level awareness to stop unauthorized DNS resolution
Dynamic detection of unauthorized DNS servers
Filter device DNS requests on any network, ensuring hybrid and remote worker protection
How it works
OpenText Core DNS Protection works by continuously monitoring all DNS traffic for signs of malicious activity. It acts as a type of firewall for all DNS resolution requests, filtering requests against our list of known DNS servers and dynamically identifying unknown DNS servers, blocking harmful queries in real-time.
The solution also provides detailed analytics and reporting, allowing you to gain insights into your DNS traffic and identify potential vulnerabilities. With automated response capabilities, it can quickly mitigate threats, ensuring the security and reliability of your DNS infrastructure.

FAQs
Protective DNS is a security service that analyzes DNS requests, comparing them against threat intelligence feeds to block access to malicious domains before a connection is made. By blocking access to harmful domains and logging DNS activity for visibility and investigation, solutions like OpenText DNS Protection can stop multiple stages of cyberattacks (phishing, malware delivery, lateral movement) and even prevent threats before they reach your devices or users.
