•Spamhaus launched free and commercial DNS Firewall services on June 15, 2026.
•The free service blocks IPs linked to malicious activities but lacks technical support.
•The commercial service offers real-time threat intelligence and broader protection against various cyber threats.

On June 15, 2026, Spamhaus announced the availability of both free and commercial DNS Firewall services. The free service offers access to DNS Response Policy Zones (RPZ) to block IPs associated with malicious activities, while the commercial service provides curated, real-time threat intelligence from expert researchers. The free service is designed for small-scale users and does not include technical support, whereas the commercial offering includes a broader range of protections against threats like phishing and malware. Users can set up accounts to access these services, but the free version may contain false positives. The commercial service aims to alleviate the burden on IT teams by automating threat blocking. Both services are compatible with major DNS solutions, enhancing network security for users.
