Akamai Edge DNS vs HARPP DDoS Mitigator: Side-by-Side Comparison (2026)

Akamai Edge DNS

Mid-market and enterprise security teams defending against DNS-layer DDoS attacks will get the most from Akamai Edge DNS, particularly those running hybrid infrastructure where on-premises DNS needs the same attack surface hardening as cloud-facing services. The Shield NS53 reverse proxy handles both environments without forcing full migration to cloud DNS, and the 100% uptime SLA backed by IP anycast routing across Akamai's global network means your authoritative DNS stays available when attackers are actively flooding it. Skip this if your DNS traffic is light and you're comfortable with basic rate-limiting from your registrar; Edge DNS is built for organizations absorbing sustained volumetric attacks, not for complexity reduction.

HARPP DDoS Mitigator

Mid-market and enterprise security teams protecting DNS and web infrastructure from sustained volumetric attacks will find value in HARPP DDoS Mitigator's hardware-based DDI detection, which processes traffic anomalies in real time across 34+ data sensors without relying on cloud scrubbing. The appliance covers both NIST DE.CM continuous monitoring and PR.IR infrastructure resilience, particularly for organizations that need localized, non-delegated mitigation. This is not the tool for shops that lack on-premises deployment capacity or those expecting a managed service; HARPP requires dedicated hardware and internal operational ownership.
