DNSSEC Validation Monitoring

Why DNSSEC Failures Are Catastrophic

When DNSSEC validation fails, validating resolvers don't return a wrong answer — they return no answer at all. From your visitors' perspective, the entire site disappears. The most common cause is a key rollover or a DS record at the registrar that quietly fell out of sync with the zone's keys. ZoneWatcher catches both before they hit production resolvers.

What We Validate

Chain of Trust

Resolve from the root down to your zone, confirming every DS / DNSKEY pair matches and validates.

DS Record Integrity

Compare the DS record published at your registrar against the DNSKEY records in your zone — the most common failure point during rollovers.

Signature Expiry

Track RRSIG inception and expiration windows so you're warned long before signatures stale out.

Algorithm Coverage

Detect zones still signing with deprecated algorithms (RSASHA1, RSASHA1-NSEC3-SHA1) so you can plan a rollover before resolvers stop accepting them.

Drift Detection During Rollovers

Key rollovers are the riskiest moment in DNSSEC operation, and the part teams most often get wrong. ZoneWatcher's checks run on a tight cadence so the window between "you finished the rollover" and "the chain validates from the root" stays small — and if anything regresses, the failure shows up in the same notification channels you already use for record changes.

Available on Protect and Control Plans

DNSSEC Validation Monitoring is included on the Protect and Control plans. It auto-provisions on every zone that publishes a DNSKEY — no configuration required. Start your free trial and we'll start watching the chain from your next check onward.
