Infoblox DNS Security & BloxOne

Every connection on your network starts with a DNS query, which makes DNS the ideal choke point for stopping threats before they ever reach an endpoint. Infoblox DNS Security transforms this foundational network service from a passive directory into an active defensive layer, analyzing DNS traffic in real time to block malware callbacks, phishing domains, data exfiltration tunnels, and command-and-control communications at the earliest possible moment. Their BloxOne Threat Defense platform is the only solution that combines protective DNS (PDNS) with full DDI (DNS, DHCP, and IP address management) in a single unified platform.

TL;DR

Protective DNS that blocks threats at the DNS layer before they reach endpoints
Only vendor combining PDNS and DDI (DNS, DHCP, IPAM) in a single platform
Real-time analysis powered by ML and threat intelligence covering 100M+ newly observed domains
Predictive DNS threat protection preempts AI-driven attacks
Native integration with AWS, Azure, and major SIEM/SOAR platforms

"Infoblox Threat Defense delivers preemptive protection by blocking threats at the DNS layer, before they spread, impact users or burden downstream tools."

The intelligence behind Infoblox's detection is substantial. Their 2025 DNS Threat Landscape Report identified 100.8 million newly observed domains, with over 25% classified as malicious or suspicious. That threat intelligence feeds directly into the BloxOne engine, enabling it to identify and block malicious domains moments after they appear. Machine learning models add predictive capability, flagging domains that exhibit characteristics of malicious infrastructure before they are even used in an attack. Independent testing by Tolly Group confirmed that BloxOne Threat Defense outperforms competitors in both detection accuracy and attack coverage, while providing deeper network visibility and more actionable intelligence sharing.

Pro Tip: Use DNS as Your First Security Layer

Configure Infoblox as the recursive DNS resolver for your entire network. Every device that makes a DNS query (which is virtually all of them) automatically gains protection without installing agents, making this one of the fastest paths to broad threat coverage across your infrastructure.

Beyond security, Infoblox's DDI platform automates the management of DNS, DHCP, and IP addresses across hybrid cloud environments. Network teams gain centralized visibility into IP allocation, automated provisioning, and policy-based management that eliminates the spreadsheet-driven chaos of manual DDI operations. The security and networking capabilities integrate natively with AWS Network Firewall, major SIEM platforms, and SOAR tools, meaning DNS threat intelligence flows directly into existing security workflows. For organizations looking to strengthen their security posture with minimal deployment friction, turning DNS into a defensive asset is one of the highest-impact, lowest-effort moves available.

Key Takeaways

DNS-Layer Defense: Blocks threats before they reach endpoints, with no agent required
Unified DDI: DNS, DHCP, and IPAM management combined with security in one platform
Predictive Intelligence: ML-powered detection flags malicious domains preemptively
Cloud Native: Native AWS and Azure integrations for hybrid infrastructure

Frequently Asked Questions

What is Protective DNS (PDNS)?
Protective DNS analyzes DNS queries in real time and blocks connections to known malicious domains, preventing malware, phishing, and data exfiltration at the network layer without requiring endpoint agents.
Does Infoblox work in cloud environments?
Yes. BloxOne Threat Defense integrates natively with AWS and Azure, and the DDI platform provides centralized management across on-premises, cloud, and hybrid environments.
