Protective DNS has evolved from best practice to an expectation: NSA and CISA jointly recommend it, national programs run it on a population scale, making it the highest-leverage, lowest-friction control organizations can deploy this quarter This article explores protective dns pdns. .
Eight services tailored to various use cases: - Fast rollout with a zero-trust path: Cloudflare Gateway - Enterprise standard, deep integrations: Cisco Umbrella - DDI-integrated protective resolution: Infoblox PDNS - Endpoint-consolidated protection: Heimdal PDNS within a unified prevention agent - Palo Alto estates: Palo Alto DNS Security Inline in existing firewall policies - SOC-centric DNS visibility: DNSSense with focused detection and analyst tooling - SMB/MSP simplicity: DNSFilter at transparent pricing, MSP multi-tenancy - Budget endpoint-DNS coverage: Comodo (Xcitium) for low-cost DNS filtering bundled with security features Choosing Our PDNS Picks We evaluated our options based on criteria aligned with NSA/CISA’s PDNS guidance, focusing on quality of threat feeds, update speed, detection capabilities beyond blocklists (such as DGA, tunneling, newly registered domains), coverage models across network egress points, roaming endpoints, and encrypted DNS, as well as logging and integration with SOC systems.
Protective DNS (PDNS) refers to a strategy that enhances network security by implementing advanced measures against potential threats, including detecting new vulnerabilities through dynamic domain name system (DNS) monitoring techniques such as Domain Generation Algorithms (DGA), tunneling methods, newly registered domains, and look-alike imitations.
