Neustar Security Services has announced the release of UltraDDR (DNS Detection and Response), a protection service based on recursive DNS that aims to prevent network breaches, ransomware attacks, phishing, and supply chain compromise. It also enforces enterprise acceptable use policies for its users.



The UltraDDR Protective DNS solution provided by Neustar enables businesses to stop communication between attackers and their targets before any harm is done. This is achieved by examining DNS requests and responding to threats. UltraDDR provides real-time observability of outbound network traffic using years' worth of historical domain data, enabling businesses to identify and thwart supply chain, ransomware, phishing, and other assaults before they do harm.

UltraDDR has the ability to track attacker assets and habits and provides a full insight into the whole threat. To enable security teams to concentrate on actual threats and reduce the noise and distraction caused by false positives, UltraDDR warnings may be combined with alerts from EDR and NDR solutions. Additionally, UltraDDR can help enforce business guidelines for acceptable internet usage with complete DNS firewall features. Administrators can select certain categories of internet traffic that are not permitted under business policies and opt to block or flag this traffic in a straightforward, unobtrusive manner.

Companies can utilize UltraDDR to meet their recursive DNS requirements. This is possible due to the global recursive DNS resolution network included in UltraDDR, which has 27 nodes spread throughout the globe offering fast resolutions everywhere. As a comprehensive DNS resolver solution, UltraDDR comes with state-of-the-art security options, including DNSSEC, DNS over HTTPS (DoH), and DNS over TLS (DoT). It also comes with built-in DNS DDoS protection using Neustar Security Services' UltraDDoS Protect solution. By integrating always-on DNS intelligence with other security information and event management systems, firewalls, endpoint solutions, and more, UltraDDR can improve businesses' current security investments in just minutes. Additionally, the client can be installed on Windows, macOS, iOS, and Android devices and supports DNS settings to remain regardless of network connectivity, providing both web categorization and threat prevention.

UltraDDR utilizes a multi-layered approach to ransomware prevention through DNS filtering. By analyzing DNS requests in real time, the service can identify and block connections to known malicious domains associated with ransomware command-and-control servers. This proactive filtering not only prevents initial infection attempts but also disrupts the communication channels that ransomware relies on to operationalize its malicious activities.

Moreover, UltraDDR incorporates sophisticated threat intelligence feeds and machine learning algorithms to continuously update its database of malicious domains. This dynamic approach enables the service to adapt to emerging ransomware threats and swiftly block new domain infrastructures utilized by ransomware operators.

The detailed reporting and analytics provided by UltraDDR offer security teams invaluable insights into the nature of attempted ransomware attacks. By dissecting blocked connections and identifying patterns, security professionals can gain a deeper understanding of the tactics employed by ransomware actors, leading to more effective defensive strategies.

UltraDDR's DNS-based approach puts it at the forefront of preventing ransomware attacks, as it operates at a foundational level in the network infrastructure. By intercepting malicious domain resolutions before any harmful traffic can reach the endpoints, UltraDDR offers a vital layer of defense against ransomware, complementing other security measures such as endpoint protection and firewalls.
UltraDDR's DNS-based service leverages real-time analysis, threat intelligence, and reporting capabilities to provide robust ransomware protection, making it an indispensable component of a comprehensive cybersecurity strategy.
