CyberNovr DNS Security (DNSSec) is a DNS-based threat protection service that blocks malicious domains and IP addresses before they can establish connections with protected systems. The service operates at the DNS layer to provide proactive threat prevention for both internal networks and customer-facing services. The solution leverages DNS protection technologies to identify and block threats in real-time. It includes continuously updated threat intelligence that enables rapid response to emerging threats and attack campaigns. The service is designed for quick deployment with minimal disruption to existing infrastructure, with implementation timelines under 2 months for cross-department projects. The platform is associated with DNS4EU, a project that provides centralized DNS protection for European public institutions. This implementation offers EU-based DNS protection with real-time threat reaction capabilities and privacy-compliant DNS resolution. The service blocks malicious domains before connections are established, reducing the risk of successful cyberattacks and data breaches. New threats and campaigns are immediately propagated to DNS resolvers, enabling security teams to block threats quickly. The solution is designed for protection of critical infrastructure and can be easily distributed to citizens and institutions.
