Nothreat Intelligent DNS is a secure DNS resolution service that prevents access to malicious domains and IP addresses associated with malware, phishing, and command-and-control servers. The service operates by intercepting and analyzing DNS queries in real-time to determine if requested domains or IPs are malicious, blocking threats at the network layer before connections are established. The platform leverages AI-driven automation and correlation mechanisms, drawing from over 100 third-party intelligence sources to curate threat feeds. This enables the system to adapt to emerging threats and provide protection against both known and unknown attack vectors. The service achieves over 99% detection accuracy with less than 1% false positives through its noise suppression engine. Intelligent DNS blocks communications to C2 servers, malware distribution sites, and phishing campaigns by denying connections at the DNS query stage. The system uses continuous incremental learning to adapt to new attacks without human intervention. It supports compliance requirements including ISO 27001 and SOC 2 by implementing DNS filtering that protects data confidentiality at the network level. The solution integrates with existing security infrastructure including firewalls, EDRs, and SIEMs. It distributes validated threat intelligence across connected security systems to provide collective immunity against newly discovered global threats.
