Protective DNS (RPZ)
Block malware, phishing, botnet C2, and infrastructure abuse using policy zones with curated intelligence.
- Fast policy decisions at resolver
- Safe responses (NXDOMAIN / sinkhole / passthru)
- Per-tenant / per-network policies
Security starts atDNS.
Reduce malware, phishing, and infrastructure abuse by enforcing policy at the earliest point of every connection — before firewalls, proxies, or endpoints can react.
Early kill-switch
Stops known-bad domains instantly
Low friction
No agents required (network control)
Telemetry
Actionable DNS events for security ops
Works for ISPs, Government, Education, and Enterprise networks.
Trusted by operators who need uptime and control:
What you get
A complete DNS platform: authoritative service, protective enforcement, encrypted transport, and operational visibility.
Encrypted DNS (DoT / DoH)
Protect users and networks from on-path interception, manipulation, and passive monitoring.
- DNS over TLS (853)
- DNS over HTTPS (443)
- Modern cipher suites and hardening
Authoritative DNS
Reliable authoritative hosting with automation for zones and records, built for high availability.
- Multi-tenant management
- Hidden primary / secondaries
- DNSSEC support
- Zero Trust Geo and Split
DNS Telemetry
Get visibility into blocked queries and suspicious behavior. Export events to your SIEM / data lake for investigation and reporting.
✓Top blocked domains, categories, and trends
✓Client IP / subnet visibility (where available)
✓Integrations: syslog, Kafka-like pipelines, or API exports
Operational Reliability
Built for operators: performance tuning, redundancy, and a deployment model that fits enterprise and ISP environments.
✓High QPS design patterns
✓Multi-site / multi-resolver architecture
✓Change control friendly (staged policy rollout)
How it works
Simple deployment. Immediate control. Clear outcomes.
1
Point clients to your resolvers
Set DHCP, router, or endpoint profiles to use your DNS resolvers (standard DNS, DoT, or DoH).
2
Enforce policy (RPZ)
Apply curated blocklists and allowlists. Choose response strategies (NXDOMAIN, sinkhole, passthru).
3
Monitor and report
Track blocked events, trends, and suspicious patterns. Export logs to your security tooling.
Why DNS is a leverage point
If you can control DNS, you can reduce exposure before a connection is established. That’s why Protective DNS is a low-cost, high-impact control across ransomware, phishing, and infrastructure abuse.
Use cases
Pick the model that fits your environment. Same platform, different outcomes.
ISP networks
Reduce bot infections and customer impact with a network-layer control that scales.
- Centralized policy, per-reseller or per-network
- Encrypted DNS options
- Reporting for ops and security
Government & Education
Improve baseline security posture and regulatory alignment with auditable controls.
- Category-based protections
- Controlled exceptions (allowlists)
- Visibility for incident response
Enterprise
Reduce phishing click-through and malicious callbacks without deploying agents.
- Policy by site, VLAN, or office
- Integrate with SIEM/SOC workflows
- Support for hybrid networks
Built for operators who cannot fail
DNS is critical infrastructure. Our approach prioritizes stability, performance, and clear operational control.
ms
Policy decisions designed for millisecond latency
24/7
Operational mindset: monitoring + incident readiness
API
Automation-first for provisioning and policy lifecycle
Replace these KPI placeholders with your real values once you’re ready (QPS, uptime targets, customers, etc.).
Deployment options
On-prem, cloud, hybrid. Multi-resolver architectures supported.
Security hardening
TLS hardening, rate limiting patterns, separation of authoritative/recursive roles.
Clear ownership
Change control, staged rollouts, and audit-friendly configuration lifecycle.
