DNS Firewall Market to Hit USD 785 Million by 2032

• The global DNS firewall market is set to expand at over eighteen percent CAGR, reaching USD 785 million by 2032.

Strong Growth Ahead

According to Allied Market Research, the DNS firewall market was valued at USD 151.6 million in 2022 and is projected to reach USD 785.1 million by 2032. This represents a compound annual growth rate of eighteen point two percent between 2023 and 2032. Growth is being driven by the adoption of bring-your-own-device (BYOD) policies in enterprises and the rapid rise of Internet of Things applications.

Deployment models include on-premise and cloud-based solutions. End-users range from DNS providers and registrars to enterprises, hosting firms, and telecom operators. Both large enterprises and small to medium-sized businesses are fueling adoption. Key industry verticals include banking and finance, government, healthcare, retail and e-commerce, education, IT and telecom, and media and entertainment.

North America and Europe remain strong markets, but Asia-Pacific is expected to be the fastest-growing region during the forecast period. Companies in the region increasingly rely on managed DNS security providers to strengthen protection while focusing on core operations.

Emerging Trends and Technology Shifts

The rise of the zero-trust security model has significantly increased the importance of DNS firewalls. In a zero-trust setup, every connection attempt must be verified, making DNS control a central security element.

Artificial intelligence and machine learning are being embedded into modern DNS firewall platforms. These technologies enable real-time traffic analysis, anomaly detection, and rapid response to suspicious activity. High-profile data breaches in recent years have accelerated demand for such proactive defenses.

The expansion of 5G networks is also expected to boost adoption. Faster data speeds and lower latency will connect more devices simultaneously, creating a greater need for DNS-layer security.

Leading Industry Players

Major companies shaping the DNS firewall landscape include IBM, Cisco Systems, Cloudflare, Comodo Group, Infoblox, Digicert, EfficientIP, BlueCat Networks, F5, and Allied Telesis. Many of these firms are enhancing solutions with advanced detection features such as behavioral analytics and machine learning.

The banking and financial services sector led the market in 2022, reflecting the growing risk of cyberattacks against digital banking platforms. DNS analytics is widely deployed to prevent denial-of-service and other DNS-based attacks targeting financial institutions.
