The Domain Name System (DNS) market is segmented on the basis of deployment types, end-users, end-use verticals, and regions. MarketsandMarkets forecasts the global DNS firewall market to grow USD 90.5 million in 2018 to USD 169.7 million by 2023, at a Compound Annual Growth Rate (CAGR) of 13.4% during the forecast period. The internet adoption and infrastructure have changed dramatically over the last few decades, which has led to the increasing trend of companies to host their information and details on the web.

The virtual appliance segment is expected to be the fastest-growing deployment type in this market, as solutions running on the Windows Operating System (OS) creates a virtual environment that resembles a completely separate computing environment. Hence, DNS Firewall services provided by virtual appliances are equivalent to the security offered by hardware appliances.

On the basis of end-users, the DNS providers segment is expected to grow at the highest CAGR during the forecast period. DNS hosts run DNS servers, which are further used and integrated by domain name registrars, website hosts, and Internet Service Providers (ISPs). Servers built by DNS hosts provide functionalities, such as domain lookup, domain translation, and DNS forwarding. Moreover, these servers maintain a list of the configured domain names that are collected from peer lookups.

The APAC region is expected to grow at the highest CAGR during the forecast period in the DNS firewall market. This is attributed to the presence of a broad internet subscriber base in several APAC countries, technological advancements in end-use verticals, and the increasing deployment of data centers and cloud infrastructure in this region.
