Domain Name System (DNS) is the foundational service that maps human-readable domain names to IP addresses. However, standard DNS is inherently vulnerable to spoofing, cache poisoning, and man-in-the-middle attacks, enabling threat actors to redirect users to malicious sites, intercept traffic, or hijack domains. DNS Trust Manager is a comprehensive solution designed to secure DNS infrastructure through DNS Security Extensions (DNSSEC), automated key management, and continuous validation, ensuring the authenticity and integrity of DNS responses.
DNS Trust Manager automates the deployment of DNSSEC across all authoritative zones. It generates and manages Key Signing Keys (KSKs) and Zone Signing Keys (ZSKs) within Hardware Security Modules (HSMs), ensuring private keys remain protected. Zone signing is performed automatically whenever zone files change, appending digital signatures (RRSIG records) that resolvers can validate to confirm data integrity.
Proper key rollover is critical to maintaining DNSSEC security. DNS Trust Manager schedules automated ZSK and KSK rollovers according to best practices, generates replacement keys, updates DS records at parent registries via secure channels, and retires old keys gracefully. This end-to-end automation eliminates manual errors and prevents service disruptions during rollover windows.
Beyond signing, DNS Trust Manager includes DNSSEC validation capabilities for internal recursive resolvers and public resolvers. It verifies signature chains, detects misconfigurations, and rejects unsigned or tampered responses. Integration with forwarders and stub resolvers ensures consistent validation policies across enterprise networks, protecting all downstream applications and users.
Continuous monitoring tracks DNSSEC status, signature expiration, and key validity across all zones. Real-time alerts notify administrators of impending signature expirations, key rollover failures, or validation errors. Dashboards display zone health metrics, signature coverage percentages, and historical rollover events. Compliance reports document DNS security posture for audits and regulatory requirements.
DNS Trust Manager integrates with domain registrars via APIs to automate DS record publication and updates. This seamless integration ensures parent zone records reflect current child-zone DS entries, maintaining a complete trust chain from the root down to the application. For multi-tenant environments, role-based controls delegate zone management while enforcing consistent security policies.
DNS-Based Authentication of Named Entities (DANE) leverages DNSSEC to publish TLSA records that bind certificates or public keys to domain names. DNS Trust Manager automates TLSA record creation and publication, allowing email, web, and IoT services to validate server certificates through DNS trust anchors, reducing reliance on public CAs.
Organizations running internal and external DNS views benefit from split-horizon configurations. DNS Trust Manager manages separate signing key sets and validation policies for internal and external zones, ensuring internal records remain isolated while external zones maintain public trust.
DNS Trust Manager supports distributed signing and validation clusters across multiple geographic regions. HSM clusters replicate key material securely to secondary sites, enabling rapid failover in case of data center outages. Automated failover of validation services ensures continuous DNSSEC enforcement during disruptions.
By establishing a complete DNS trust chain from root zone validation through child-zone signing and resolver enforcement DNS Trust Manager guarantees that users and applications reach genuine endpoints. It transforms DNS from a vulnerable service into a robust, cryptographically secured foundation for internet communications.
DNSSEC adds digital signatures to DNS records, enabling resolvers to verify authenticity and integrity. It prevents attackers from spoofing DNS responses and redirecting users to malicious sites.
It schedules KSK and ZSK rotations, generates new keys in HSMs, updates DS records at registrars via APIs, and retires old keys—all without manual intervention—ensuring seamless DNSSEC maintenance.)
Yes. It integrates with internal recursive resolvers and stub resolvers to perform signature validation, reject tampered responses, and enforce DNSSEC policies across enterprise networks.
DANE uses DNSSEC to publish TLSA records that bind TLS certificates or public keys to domain names, enabling clients to validate server certificates via DNS trust chains instead of public CAs.
The solution deploys distributed HSM and validation clusters across multiple regions. It replicates key material securely for failover and uses load balancing to maintain continuous signing and validation services.
