DNS Firewall

A DNS Security solution such as DNS Firewall plugs into domain name resolution to prevent access to risky and inappropriate domains. It allows organizations to prevent users from visiting risky domains and re-directs them to a block page in case they try to visit a blocked domain.

Benefits of a DNS security solution

DNS security solution is very simple to deploy and manage at scale. There is no need for network architecture and the involvement of the network team is minimal. It scales to users and devices outside of the corporate network. Policy enforcement is simple wherein account admins can easily block domains which pose a security threat in addition to inappropriate category of domains with just a click. In summary, the benefits of a DNS security solution covering all ports and protocols across the entire organization both on and off site provide significant value as the first line of defense.

Does DNS Firewall impact performance of my DNS resolution?

Adding a layer of DNS security might seem like an impact on the DNS query resolution performance. On the contrary, an effective DNS firewall solution will help speed up access by distributing DNS queries intelligently to the nearest available resolvers therby improving the overall DNS query resolution performance. In addition, our users normally experience better performance not only at the DNS resolution point but even after a connection is established with the server. This is due to the fact that users are always directed to the nearest available server for a domain given the location of the user. This significantly improves the user's experience.
