bell

EnterpriseCybersecurity made easy.

Atrios delivers high-performance DNS load balancing, real-time query telemetry, authoritative zone hosting, and AI-powered threat control in a single unified architecture.

Unified DNS Protection &Intelligence

Transform your DNS from a vulnerable blind spot into your primary line of defense. Deliver line-rate traffic filtering, live packet inspection, and authoritative zone management across global hybrid environments.

Carrier-Grade PFD

Distributed Packet Filter Daemons handle line-rate DNS load balancing, DDoS defense, ACL enforcement, and sub-millisecond query routing.

DNS Flow Telemetry

Real-time deep query inspection displaying timestamps, client IPs, destination countries, protocols, and instant filter drilldown.

Multi-Tiered Defense

50+ threat categories, 100+ app signatures, regex/TLD filters, dynamic allow/denylists, and automated sinkholing.

Authoritative Zones

Comprehensive forward & reverse zone management, complete DNS record sets (A, AAAA, MX, TXT, SRV), and delegation.

Engineered for Massive Scale:
The Atrios Hybrid Architecture

Atrios decouples packet ingress from recursive resolution, delivering sub-millisecond query performance,
carrier-grade resilience, and controlled configuration deployment across multi-node topologies.

Ingress Layer

Packet Filter Daemons (PFD)

High-throughput, Anycast-ready DNS load balancers and traffic gateways. PFDs handle line-rate query ingress, IPv4/IPv6 dual-stack routing, hardware-accelerated ACL drops, and dynamic rate limiting to stop volumetric DDoS attacks before they touch upstream resolvers.

  • Anycast & Multi-IP Load Balancing
  • Automated ACL Drops & Rate Limiting
  • Health Probing & Zero-Downtime Failover
Resolution Engine

Backend DNS Modules (BDM)

Intelligent recursive resolvers delivering lightning-fast DNS resolution. Features sub-millisecond in-memory caching, latency-optimized upstream forwarders, real-time threat policy evaluation, and transparent sinkholing of malicious domains.

  • In-Memory Cache with High Hitrates
  • Latency-Optimized Resolver Forwarding
  • Automated Sinkholing & Redirection
Staging & Deployment

Safe "Commit to Atrios"

Eliminate risk when managing mission-critical infrastructure. Operators stage, review, and validate filtering rules, zones, and load-balancer configurations before deploying via "Commit to Atrios", with full deployment logs and instant one-click rollback.

  • Staged Rule Review & Pre-Flight Check
  • Atomic Cluster-Wide Configuration Sync
  • Commit History with One-Click Rollback

Multi-Layered Policy Engine:
Intelligent Filtering & Threat Control

Atrios inspects DNS requests against granular security policies, category classifications,
and application signatures to protect users, sites, and workloads across the enterprise.

50+ Category Filtering

Filter out unwanted or dangerous resources across 50+ pre-classified categories including malware, phishing, ransomware, cryptojacking, violence, and adult content with toggleable rules.

100+ App Signatures

One-click discovery and blocking of popular applications across social networks, streaming media, file sharing, gaming, and anonymizer VPN proxies that bypass security perimeters.

Keyword & TLD Rules

Enforce regex and wildcard keyword matching, and block entire suspicious top-level domain suffixes (such as high-risk TLDs) to prevent newly registered malicious domains from resolving.

Allowlist & Denylist Engine

Deploy custom domain and category allowlists and denylists at organizational or site levels. Supports bulk CSV import/export for seamless migration of enterprise security lists.

IP Whitelisting & Filtering

Control DNS access by client IPv4/IPv6 address or CIDR range. Restrict resolver endpoints exclusively to trusted enterprise egress IPs and branch office subnets.

DNS Redirection & Sinkholing

Transparently steer malicious queries away from command-and-control servers toward remediation sinkholes, branded block pages, or quarantine notification endpoints.

Carrier-Grade DNS Security &
Real-Time Policy Enforcement

Distributed across Anycast edge nodes, Atrios intercepts threats before connections establish, optimizing internet latency while guaranteeing compliance.

  • AI/ML Threat Intelligence (Dragonfly, URLhaus, OpenCTI)
  • 50+ Web Security & Content Filtering Categories
  • 100+ Application Discovery & Granular Blocking
  • Keyword, Regex & Top-Level Domain (TLD) Rules
  • Safe "Commit to Atrios" Deployment with Rollback

Deep Telemetry & Visibility:
Real-Time DNS Flows & Granular Analytics

Gain unparalleled visibility into enterprise network activity with packet-level DNS query flow inspection
and comprehensive time-series analytics powered by ClickHouse.

Frequently Asked Questions:
Technical & Architectural Details

Explore how Atrios integrates into modern enterprise networks, handles massive query volume,
and satisfies stringent security and compliance requirements.

Atrios separates ingress traffic management from recursive resolution. Packet Filter Daemons (PFD) operate at line-rate to handle Anycast ingress, DDoS defense, and rate-limiting. Queries requiring resolution pass to Backend DNS Modules (BDM) with an optimized in-memory cache and latency-based upstream forwarders, consistently maintaining sub-millisecond response times.
