On top of PowerDNS Recursor, the Infrastructure Malware Protection add-on equips recursive solutions with system-wide DNS-based filtering. This provides protection against malware, phishing, and other malicious attacks for all subscribers. It also provides a convenient way for Internet Service Providers to ensure they protect their customers by blocking malicious DNS requests.
On a more granular level, per subscriber control options or per device filtering settings can be achieved by using PowerDNS Protect, instead of Infrastructure Malware Protection.
