Top PDNS Services for Organizations: A Guide to Enhanced Cybersecurity

Protective DNS (PDNS) services have become an essential tool for organizations seeking to enhance their cybersecurity. According to recent guidance from the NSA and CISA, PDNS is a best practice that should be implemented by all organizations to protect against phishing, malware delivery, and command-and-control traffic.

The most effective PDNS services are those that offer a combination of threat intelligence, policy enforcement, and detection capabilities. Cloudflare Gateway stands out as the top pick for fast rollout with a zero-trust path, offering free-to-start pricing and massive resolver network coverage.

Other notable picks include Cisco Umbrella, which is ideal for enterprises seeking a proven PDNS standard; Infoblox, which offers DDI-integrated protective resolution; Heimdal, which provides endpoint-consolidated protection; Palo Alto Networks DNS Security, which is designed for PA firewall estates; and DNSSense, which focuses on SOC-centric DNS visibility.

When selecting a PDNS service, organizations should prioritize threat-feed quality, detection capabilities beyond blocklists, coverage models, logging and SOC integration, and operational fit. The correct choice will depend on the specific needs and requirements of each organization.
