Conducting large-scale business online entails a certain risk. Having the appropriate plan and a solid set of security technologies, on the other hand, can greatly improve your chances of keeping your infrastructure and user data safe. DNS firewalls should be a key component of every company’s cybersecurity plan. If you don’t have one, your business and consumers may be jeopardized.
In this post, we’ll look at how DNS firewalls function, enterprise-grade firewalls for DNS, and why they’re beneficial to a company’s IT infrastructure.

What is a DNS firewall?
DNS Firewall is a network security solution that protects your devices from malware attacks by blocking DNS resolution for known-malicious domains. In basic terms, it protects your personal information by preventing you from connecting to known harmful Internet sites.
To top it off, DNS Firewall lets you block sites with bothersome pop-up windows and inappropriate content (like gaming, gambling, adult sites).
From an enterprise perspective, IT employees must collaborate to ensure that all DNS records are updated across the firm. Based on the size and design of your network, you might need to run your internal DNS server to help route traffic to different destinations. Because a domain name is typically one of the most important things a company owns and a crucial element of your branding, it’s critical to keep DNS names and routes secure.
How does DNS Firewall work?
When an end-user seeks to access a website/domain, the responder will first query a root server, then a top-level domain server, and ultimately the web’s server, which will complete the end-request user’s resolution. Regardless of whether the site is harmful or not, the client’s request to visit it will be executed.
DNS Resolver with DNS Firewall: “Zones,” which are collections of threat intelligence data, are examined during the resolution process. The requested domain is compared to the data sets for potential security issues, and if a match is found, the request is denied or diverted.
Remember that if you use a VPN, there’s a chance it’ll interfere with your firewall. This dispute must be resolved to avoid DNS leaks from either software, which could result in a network compromise. For instructions on how to correctly configure your VPN, consult the documentation or contact support. While most VPNs come with an easy-to-use program for connecting on Windows, there are fewer VPNs that are suggested for Mac users. Most of them require you to connect to it manually, which increases the risk of a firewall clash.
Why DNS Firewalls are Essential for Enterprise Security?
Enterprises with a strong web presence are constantly battling to support legitimate user traffic while avoiding external threats. Every day, hackers devise new techniques to access networks and execute various sorts of malware, making this more challenging.
Depending on the needs of your company’s network, firewalls can be installed at various tiers of IT infrastructure. Most firewalls were real hardware devices that you would connect to the edge of your network so that all outside traffic would pass through it first in the early days of the internet.
Firewalls have become increasingly software-focused as the cloud model has gained traction across numerous industries. Several big manufacturers now provide firewall services to supplement your existing infrastructure. You should inquire about the firewall protection provided by your hosting provider.
