We track the nameservers assigned to a domain and alert when a nameserver has changed. This helps prevent any kind of DNS takeover attacks and ensures your domains always point to the correct DNS infrastructure.
Nameservers are the foundation of your domain's DNS infrastructure. They determine which DNS servers are authoritative for your domain and ultimately control where your traffic is directed. Any unauthorized change to your nameservers can have severe consequences.
If nameservers are changed to non-functional servers
Malicious actors redirecting your visitors to their servers
MX records become ineffective with wrong nameservers
Attackers gaining control of your DNS resolution
Nameserver changes often go unnoticed until services start failing. Traditional monitoring might miss these changes or detect them too late to prevent significant business impact.
ZoneWatcher continuously monitors the nameserver assignments for all your domains through WHOIS record analysis. When any nameserver change is detected, you receive immediate alerts with comprehensive details.
DNS takeovers occur when attackers gain control of your nameservers or change them to servers they control. This sophisticated attack vector is increasingly common and can have devastating consequences.
Not all nameserver changes are malicious - your team might legitimately change DNS providers or update nameserver configurations. ZoneWatcher helps you distinguish between authorized and potentially malicious changes.
ZoneWatcher provides comprehensive nameserver protection at multiple levels of the DNS hierarchy to ensure complete coverage.
