Akamai Edge DNS: enterprise authoritative DNS with 100% availability and built‑in DDoS resilience
Akamai Edge DNS secures and accelerates your domains on the world’s most distributed edge platform. It delivers a 100% uptime SLA, absorbs large-scale DNS attacks, reduces page latency with global anycast and caching, and gives you intuitive, API-first management — including Terraform support — to operate at scale.
100% uptime SLA backed by a multilayered, globally distributed architecture.
DNS resources segmented across non‑overlapping clouds to minimize correlated failure risk.
Secondary DNS for added protection of primary resources and nonstop resolution.
Protection against sophisticated DNS attacks
Shield NS53: a bidirectional reverse proxy that protects on‑prem and hybrid DNS assets (e.g., GSLBs, firewalls, nameservers) from resource‑exhaustion, including NXDOMAIN floods.
Drop NXDOMAIN queries at the edge with self‑configurable, real‑time policies.
Mitigations for source address spoofing and controls that prioritize trusted recursive resolvers.
DNSSEC support to prevent DNS forgery and cache poisoning.
No DDoS overage fees — even during modern, high‑volume incidents.
Performance and reduced origin load
Global IP anycast on Akamai’s NAMES network routes users to the closest responder.
High cache‑hit ratios for faster answers and lower origin/GSLB load.
Integrated traffic management and zone apex mapping for optimal app/API performance.
Operational simplicity and visibility
Full automation via APIs and Terraform; self‑service UI for policies, rate controls, and zone transfers.
Analytics with insights during peacetime and under attack.
Unified posture: combine Edge DNS with Shield NS53, plus optional add‑ons like DNS Posture Management and Prolexic.
Configure: Define primary and secondary zones via APIs or Terraform in Akamai Control Center.
Secure: Enable DNSSEC and apply dynamic, self‑managed security policies at the edge.
Deploy: Provision, delegate, and update zones across cloud or on‑prem environments.
Monitor: Track traffic and availability, and monitor for brand spoofs and phishing domains.
Akamai vs. other enterprise cloud DNS and security solutions
Edge DNS is designed for high availability, performance, and defense against DNS‑based attacks, and it also addresses hybrid/on‑prem realities many enterprises face.
Akamai vs. Cloudflare for DNS posture management and protection
Posture management
Akamai offers dedicated DNS posture capabilities through Akamai DNS Posture Management and monitoring for brand spoofing and phishing domains. This complements Edge DNS to maintain configuration hygiene and visibility.
Protection
Both vendors provide globally anycasted authoritative DNS and DDoS mitigation. Akamai differentiates with Shield NS53 — a reverse proxy that specifically protects on‑prem and hybrid DNS (including GSLBs) and lets you dynamically drop NXDOMAIN floods at the edge.
Edge DNS integrates with Prolexic, Akamai’s purpose‑built platform for volumetric and multi‑vector DDoS protection across layers, ports, and protocols.
Akamai vs. Imperva for DNS posture management and protection
Posture management
Akamai combines authoritative DNS, posture management, and analytics to unify DNS security across cloud and on‑prem estates. DNS Posture Management helps identify misconfigurations and exposure while Edge DNS/Shield NS53 deliver enforcement.
Protection
Both vendors mitigate DNS attacks at scale. Akamai’s architecture adds segmentation across non‑overlapping clouds and Shield NS53 to defend legacy or compliance‑bound on‑prem DNS, reducing risk without forcing migration.
How Edge DNS differs from Cloudflare DNS on sophisticated attacks and availability
Availability
Edge DNS provides a 100% uptime SLA and segments DNS across non‑overlapping clouds, designed to minimize systemic or correlated failures. Secondary DNS further hardens availability.
Attack mitigation
Edge DNS enables customer‑controlled, dynamic defenses — including dropping NXDOMAIN at the edge and prioritizing trusted resolvers — and integrates with Prolexic to contain large, multi‑vector events that aim to exhaust DNS, GSLBs, or adjacent infrastructure.
Hybrid/on‑prem protection
Shield NS53 uniquely extends reverse‑proxy protections to on‑prem and hybrid DNS assets, shielding them from resource exhaustion while improving performance with caching.
What to look for in a highly distributed, secure edge DNS (and how Akamai maps)
Uptime and resiliency
Look for a 100% uptime SLA, global anycast, and architectural isolation to prevent correlated failures. Akamai provides 100% SLA and non‑overlapping clouds with secondary DNS.
DDoS resilience without surprise costs
You want mitigations for volumetric floods, reflection/amplification, and NXDOMAIN attacks — with predictable pricing. Akamai includes real‑time policies and no DDoS overage fees.
Security controls at the edge
DNSSEC, rate controls, spoofing mitigations, and the ability to prioritize trusted recursors. Akamai offers all of the above, configured via UI or APIs.
Hybrid/on‑prem coverage
If you can’t move all zones to the cloud, ensure the provider can protect on‑prem GSLBs and nameservers. Akamai’s Shield NS53 is built for this use case.
Performance at scale
Global anycast, high cache efficiency, and integrated traffic management to reduce page latency and origin load. Akamai’s NAMES network, caching, and integrated traffic management deliver these benefits.
Automation and tooling
APIs, Terraform support, and DevOps‑friendly workflows for large record sets and frequent changes. Akamai supports API‑first operations with Terraform.
Visibility and posture
Analytics for peacetime and attack scenarios, with posture management to prevent misconfigurations. Akamai provides analytics and DNS Posture Management.
Enterprise readiness
Support for large zones/record counts, secondary DNS, zone apex mapping, and integration with broader DDoS protection. Akamai includes these plus Prolexic integration.
Who benefits from Edge DNS
Global enterprises requiring an SLA‑backed 100% available authoritative DNS.
Regulated or hybrid organizations that must protect on‑prem nameservers and GSLBs.
High‑traffic digital properties needing low‑latency resolution and reduced origin load.
Teams that want DevOps automation and real‑time, self‑service security controls.
