Enterprise-grade DNS infrastructure for telecom operators and ISPs. Carrier-class caching, policy-driven resolution, and real-time security — all from a single platform.
A complete DNS-as-a-Service infrastructure with high-performance caching, multi-tenant isolation, and programmable policies.
In-memory caching engine delivering sub-millisecond response times. Optimized for millions of concurrent queries.
Isolated DNS configurations per destination IP:port. Each virtual server maintains independent policies, lists, and resolution rules.
Domain and list-based access control with flexible actions: DROP, NXDOMAIN, REFUSED, REDIRECT (A/AAAA), and SERVFAIL per policy rule.
Define block and redirect rules per content category — malware, adult, social media, gambling — without upstream DNS changes.
Support for DOMAIN and SHA1-hash based blocklists. Add, delete, and manage lists via API with real-time capacity tracking.
RESTful management and client APIs with full documentation. Complete automation via API keys with key/secret authentication.
Subscriber-level content filtering with age-appropriate profiles. Protect children from harmful content through DNS-based policy enforcement.
Operator-grade Safe Internet service with DNS-level content blocking. Enable clean browsing experiences across your entire subscriber base.
Full compliance with national access blocking and content filtering regulations. Ready-to-deploy for ISP and telecom regulatory requirements.
Seven layers of DDoS and abuse protection built into the core engine. Real-time threat mitigation without external dependencies.
Per-client and per-domain rate limits against NXDOMAIN attack floods targeting your resolver infrastructure.
Response rate limiting per client IP prevents your DNS infrastructure from being weaponized in reflection attacks.
Token bucket rate limiting with configurable burst allowance. Absorb traffic spikes while blocking sustained attacks.
Built-in protections against cache poisoning attempts with randomized source ports and transaction IDs.
Connection limits per client and globally to prevent resource exhaustion from TCP-based DNS floods.
Graceful handling and rejection of malformed DNS packets that could exploit parser vulnerabilities.
Scalable query processing with upstream deduplication, destination-IP routing, and horizontal scaling.
HexaDNS is engineered for telecom-scale deployments with multi-worker query processing and intelligent upstream resolution.
Modern web-based console with RBAC, real-time monitoring, and comprehensive DNS reporting.
Real-time DNS statistics, hit ratios, query types, and system health at a glance.
Granular role-based access control with custom permissions, user management, and audit logs.
Historical data with top domains, top clients, query type breakdowns, and daily trends.
Detailed security hit tracking, attack metrics, and real-time threat visibility.
CPU, memory, disk, and network monitoring with historical graphs and hardware specs.
Configure and manage isolated DNS instances with per-server listener and policy settings.
Manage API access with key/secret pairs for programmatic integration and automation.
Complete audit trail with user activity tracking, change history, and compliance support.
Distributed HexaDNS nodes across multiple regions deliver ultra-low latency DNS resolution through Anycast routing.
Flexible deployment options from bare-metal appliances to fully containerized cloud environments.
Production-ready Docker Compose and container orchestration with Nginx load balancing.
Dedicated hardware deployments in multiple capacity tiers — from branch offices to core network.
VMware, KVM, Hyper-V, and public cloud platforms with elastic scaling and cost efficiency.
