DNS firewall market seen tripling by 2032

By AI, Created 7:36 AM UTC, May 27, 2026, /AGP/ – The global DNS firewall market is projected to grow from $151.63 million in 2022 to $785.1 million by 2032, driven by rising cyberattacks, cloud adoption and demand for stronger threat protection. Allied Market Research says BFSI led the market in 2022, while Asia-Pacific is poised for the fastest growth through the forecast period.

Why it matters: - DNS firewall tools are becoming a core layer of enterprise cybersecurity as phishing, ransomware and DNS-based attacks become more common. - The market’s projected rise to $785.1 million by 2032 signals sustained demand for threat blocking before malicious traffic reaches networks, endpoints or applications. - Cloud migration, remote work and digital transformation are expanding the attack surface for organizations across industries.

What happened: - Allied Market Research valued the global DNS firewall market at $151.63 million in 2022. - The firm projects the market will reach $785.1 million by 2032, implying a 18.2% compound annual growth rate from 2023 to 2032. - The report says demand is being fueled by stronger cybersecurity spending worldwide. - The report is available as a downloadable PDF brochure.

The details: - DNS firewalls block malicious internet domains and filter suspicious DNS requests before a connection is established. - The technology helps detect phishing, malware, ransomware and data exfiltration attempts. - DNS firewall systems use DNS response policy zones, threat intelligence feeds and real-time analytics. - Cybercriminals are using DNS hijacking, cache poisoning, tunneling and distributed denial-of-service attacks to target enterprise systems. - AI and machine learning are improving DNS firewall platforms by spotting anomalies, lowering false positives and speeding up mitigation. - Cloud-based DNS firewall products offer centralized management, scalable deployment and real-time monitoring across multi-cloud environments. - The BFSI segment held the largest market share in 2022. - The enterprise segment led end-user adoption in 2022. - On-premise deployment generated the highest revenue in 2022. - Asia-Pacific is expected to be the fastest-growing region during the forecast period. - North America held the largest revenue share in 2022. - The report identifies Cisco, Cloudflare, Infoblox, BlueCat Networks, EfficientIP, DigiCert and Comodo as active vendors. - A full report purchase option is also listed.

Between the lines: - Financial services remains a prime target because it concentrates high-value customer and transaction data. - On-premise deployment still leads because regulated industries want tighter data control and compliance support. - The report’s regional split suggests cybersecurity spending is broadening beyond mature markets as digital adoption accelerates in Asia-Pacific. - The company’s mention of IBM, SAP and F5 highlights a wider industry push toward AI-enabled automation and cloud-native DNS management.

What’s next: - Vendors are expected to keep adding AI, predictive analytics and automation to reduce response time and improve detection. - Enterprises are likely to fold DNS security into broader zero-trust and threat-intelligence frameworks. - Demand should stay elevated as ransomware, cloud use and remote access risks continue. - The market is expected to remain a key part of the cybersecurity stack through 2032 and beyond.

The bottom line: - DNS firewall spending is shifting from niche protection to an essential defense layer as attackers increasingly exploit the DNS pathway.
