Nominum

Nominum is a provider of DNS-based networking and security software used by communications service providers and large enterprises to manage and secure IP address resolution and subscriber traffic.

• Domain Name System (DNS) software platforms (DNS infrastructure) for carrier-grade recursive and authoritative name resolution.
• Network security solutions (network security) that use DNS data to detect and mitigate malicious domains and threats.
• Subscriber and policy control capabilities (policy management) for applying granular access and filtering rules at the DNS layer.
• Analytics tools (network analytics) that interpret DNS and traffic data for visibility into usage patterns and threats.
• Deployment and integration services (professional services) to align DNS and security architectures with operator environments.

More About Nominum

Nominum focuses on DNS-centric software platforms that System Integration Testing (SIT) in the core of service provider and enterprise IP networks. Its software is designed to provide carrier-grade recursive and authoritative DNS services, delivering name resolution at scale while enforcing policies on queries and responses. These DNS servers integrate with existing IP network infrastructure and are deployed in data centers or distributed Points of Presence (PoP) to support high subscriber volumes and traffic loads.

The company’s offerings align with networking and security solution categories. On the networking side, Nominum provides DNS infrastructure (DNS infrastructure) that supports standard DNS protocols such as User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) over IPv4 and IPv6, integrates with Dynamic Host Configuration Protocol (DHCP) and IP address management environments, and can participate in broader subscriber management architectures. On the security side, Nominum delivers DNS-based protection (network security) that relies on continuously updated threat intelligence about malicious domains, phishing sites, and botnet command-and-control hosts. DNS queries are evaluated against policy and reputation data to block or redirect suspicious domains before connections are established at higher layers.

Nominum’s platforms are used by communications service providers, broadband operators, and mobile carriers that require scalable DNS and security controls close to the subscriber edge. By operating at the DNS layer, these solutions give operators a control point that is independent of end-user devices and can enforce policies for both fixed and mobile access. Enterprises can use Nominum technology in a similar way, applying DNS-based filtering and access control across branch locations, corporate campuses, or remote user traffic.

From a technical perspective, Nominum’s solutions are typically integrated with external systems such as subscriber databases, policy control functions, and Security Operations (SecOps) tools. This integration allows DNS policies to be applied per user, device, or service tier, and supports logging and analytics for operational visibility. DNS telemetry feeds into analytics (network analytics) that provide operators with insights into traffic volumes, application usage, and emerging threats, which can then inform capacity planning and security response.

Within an enterprise technology directory, Nominum can be categorized under DNS infrastructure, network security, and network analytics. Its core value proposition centers on using DNS as an architectural control point for name resolution, security enforcement, and traffic visibility, enabling service providers and enterprises to manage connectivity, protect users from domain-based threats, and gather operational data from a foundational Internet Protocol (IP) service.
