OpenText Core DNS Protection review
Centralized, endpoint-aware DNS protection for distributed security teams.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenText Core DNS Protection is a cloud-native DNS security service for organizations, managed service providers, and hybrid workforces. It filters DNS requests from browsers, applications, and background processes, helping security teams block malicious domains, ransomware, phishing activity, and DNS-based communication with command-and-control servers. Endpoint agents extend filtering to remote and hybrid workers on any network, while centralized policies apply consistent controls across the organization.
Pricing is handled through sales or partners, and the available offer is a 30-day trial rather than a free plan. The service’s main strength is the depth of its DNS control: it can block unauthorized DNS resolution, including DNS over HTTPS and DNS over TLS, while providing agent-level awareness of which processes are resolving domains. Logs of DNS requests and responses support investigations and compliance reporting, and drill-down reporting adds visibility into DNS activity and threats.
Core DNS Protection is suited to teams that need centralized policy enforcement across changing network environments rather than a basic domain blocklist. Its scope covers malware blocking, phishing prevention, command-and-control protection, adult content filtering, per-device policies, activity logs, and analytics. Organizations that need remote-worker coverage and detailed DNS investigation should consider it; those prioritizing a free plan, published entry pricing, or a broader set of listed platform options should look elsewhere.
