F5 BIG-IP DNS vs Infoblox DNS Infrastructure Protection: Side-by-Side Comparison (2026)

F5 BIG-IP DNS

Enterprise and mid-market security teams needing DNS-layer DDoS defense at scale should evaluate F5 BIG-IP DNS for its ability to absorb volumetric attacks while maintaining authoritative DNS availability; the 100 million RPS capacity and integrated GSLB mean you're not bolting on a separate DDoS appliance. The tool maps cleanly to NIST PR.IR for infrastructure resilience, though its monitoring and anomaly detection lag behind dedicated threat detection platforms. Skip this if your organization needs DNS security to also cover recursive resolver hardening or advanced query-pattern analytics; BIG-IP DNS is built for the authoritative side of the nameserver equation.

Infoblox DNS Infrastructure Protection

Mid-market and enterprise security teams defending distributed DNS infrastructure will get the most from Infoblox DNS Infrastructure Protection because it stops DNS-layer attacks at scale without requiring constant rule tuning; its integration with Threat Adapt intelligence and real-time attack pattern visibility map directly to NIST DE.CM continuous monitoring across external and internal nameservers. On-premises deployment gives you control over DNS resilience when cloud-based alternatives feel too far removed from your core infrastructure, though this also means you're maintaining appliances yourself. Skip this if your organization lacks DNS-specific monitoring expertise or expects a managed service model.
