The global managed domain name system market size was estimated at USD 1.56 billion in 2024 and is projected to reach USD 4.14 billion by 2030, growing at a CAGR of 18.2% from 2025 to 2030. The market’s expansion is primarily driven by the increasing demand for enhanced cybersecurity measures and the need to protect digital infrastructure from evolving cyber threats.

DNS infrastructure is a common target for Distributed Denial-of-Service (DDoS) attacks, domain hijacking, and cache poisoning, which can severely disrupt online operations. Managed DNS providers address these threats by offering advanced security solutions, including DDoS mitigation, DNSSEC (Domain Name System Security Extensions), and traffic filtering. By outsourcing DNS management to specialized providers, businesses can leverage robust security protocols, continuous monitoring, and rapid threat response, ensuring that their websites and online applications remain secure from malicious attacks. As cyber threats continue to evolve in complexity and frequency, organizations increasingly recognize the importance of managed DNS services with integrated DDoS protection to safeguard their digital assets and maintain operational continuity.

In addition to security, the need for improved network performance, reliability, and uptime is a major factor driving the adoption of managed DNS services. Traditional, in-house DNS infrastructures, such as self-managed anycast networks, often fall short in meeting modern business demands for high availability and fast response times. In contrast, managed DNS services provide enhanced uptime guarantees through robust infrastructure, real-time monitoring, and automated failover mechanisms. In the event of a DNS server failure or an attack, traffic is automatically rerouted to backup servers, minimizing downtime and ensuring uninterrupted access to websites and applications.

As businesses increasingly rely on their online presence for revenue generation, customer engagement, and service delivery, ensuring high network reliability and consistent uptime has become a critical priority. These requirements, combined with growing cybersecurity concerns, are driving the widespread adoption of managed DNS services and anycast networks, as they offer both resilient performance and strong protection against cyber threats.
