Renewal notices land in an inbox nobody checks. A colleague changes an MX record and email stops. Someone points a subdomain at a decommissioned server and it becomes a takeover target. DNSGuard watches every domain and every record you own and tells you the moment anything changes — or is about to.
An expired card at the registrar, a departed employee's account, a typo in a record. The damage is the same as a hack — and far more common.

DNSGuard checks from multiple locations worldwide and keeps a versioned history of your entire DNS.
Registrar-independent. DNSGuard reads WHOIS/RDAP, tracks expiry dates, auto-renew status and registrar lock, and alerts 60, 30, 7 and 1 day out.
A, AAAA, CNAME, MX, TXT, NS, SRV — any change is detected within minutes and compared against the previous version. Planned or not, you'll know.
See how a change propagates across resolvers worldwide. Know when it's safe to switch, and catch resolvers still serving stale data.
Nameserver changes, unexpected registrar transfers, subdomains pointing at deleted cloud resources. The classic takeover paths, flagged before they're used.
SPF, DKIM and DMARC validated continuously. Get warned when a record breaks deliverability — before your invoices land in spam.
Every record, every version, with timestamps. Roll back mentally in seconds: 'what did this zone look like last Tuesday?' is one click away.
Nothing to install. Add your domains and DNSGuard starts watching from the outside, like the rest of the internet does.
Paste the list or import from your registrar. DNSGuard pulls expiry data and takes a full snapshot of every zone.
Flag planned changes so they don't alert. Anything else does.
Email, Telegram, Slack, Teams or webhook. Route expiry alerts to finance and record changes to IT if you like.
Upcoming renewals, changes made, propagation status, email-security health. Five minutes, once a week.
Priced per monitored domain, records included.
