What is DNS Monitoring?

DNS Monitoring is used to ensure that communication between browsers and websites or domains remains accurate. Domain names of services or websites are often used by end users without question, with a high level of trust. As a result, domain misconfigurations or even domain theft can pose significant security risks.

Regardless of whether your company is responsible for managing just one or several domains, DNS monitoring can help to quickly diagnose issues, prevent targeted attacks, and promptly identify any possible security gaps.

DNS is often a popular entry point for hackers, so it's essential to keep an eye on DDoS, DoS, DNS poisoning, or domain theft.

With a one-time configuration, DNS Monitoring can automatically supervise these critical points of attack and ensure security, allowing you to focus on other tasks.

How does DNS Monitoring work?

In short, a DNS monitor oversees name server records. For all A and C entries, IP addresses are validated. For SOA, NS, MX, SRV, additional entries are validated as well.

Regular checks ensure that there are no unwanted or malicious changes to the record entries. External checks also confirm that no third-party record overwriting occurs.
