How to Choose a DNS Security Solution

Selecting the optimal DNS security solution requires a strategic decision on where DNS security should be primarily enforced:

• Cloud Resolvers: Solutions like Cisco Umbrella, Cloudflare Gateway, DNSFilter, and Akamai offer speed and effective protection for roaming users.
• DDI Platforms: If you manage your own DNS, DHCP, and IPAM (DDI), Infoblox, BlueCat, and EfficientIP provide query-level attribution and integrated security.
• Firewall Integration: For organizations prioritizing policy consolidation, Palo Alto DNS Security integrates directly into existing firewall infrastructure.

Additionally, it is crucial to evaluate solutions against the realities of 2026 threats:

• Encrypted DNS Handling: Verify how each vendor maintains visibility when applications utilize DoH/DoT. Solutions should offer their own encrypted endpoints, roaming clients, or inline analytics. Blocking external DoH resolvers is a standard best practice.
• Advanced Detection: Look beyond simple blocklists. Demand evidence of capabilities in detecting sophisticated threats such as tunneling, DGAs, and lookalike domains.
• Logging Economics: DNS telemetry is invaluable for the SOC. Ensure that the solution allows you to affordably collect and store these logs for analysis.

Implementing DNS security represents one of the most cost-effective measures to prevent attacks. Integrate it strategically with your Zero Trust program and protective DNS strategy to maximize its impact.

What You Should Do

• Assess Your Needs: Determine if your priority is cloud-based speed, DDI-integrated control, or firewall-based policy consolidation.
• Verify DoH/DoT Handling: Actively question vendors on their approach to encrypted DNS to ensure continued visibility and control.
• Demand Advanced Detection: Prioritize solutions that offer behavioral analytics for threats like tunneling and DGAs, not just basic blocklists.
• Plan for Log Storage: Allocate budget and resources for collecting and storing DNS security logs, as they are crucial for incident response and threat hunting.
• Integrate with Zero Trust: Ensure your chosen DNS security solution supports and enhances your overall Zero Trust architecture.
