Everything DomainDrift does

Continuous, signed telemetry for the domain layer: who runs a domain's DNS, mail, certificates and hosting, what changed today across the whole index, and what changed on the domains you care about. This page is the complete list, with exactly what each lane gets. Amounts live on pricing.

The signed record

Every observation is Ed25519-signed at the moment it is taken, chained to the one before it, and archived. The signature proves attribution and integrity: that we published exactly these bytes, and that nothing changed since. It is added accountability on top of the data, not a claim that the data is correct.

Live views of the whole index

The daily read on what the internet actually did: who moved, who is winning, who is dark. Every view is computed from the same signed observations, so two pages can never tell you different numbers.

Monitoring your own domains

Put a domain under watch and it is re-checked every 5 minutes: nameservers, mail, certificate, DNSSEC and reachability. The signed history is kept, and anything material reaches you the moment it happens.

Evidence you can hand to someone else

The point of signing is that the record survives leaving us. Exports carry their receipts, so an auditor, a customer or a court can check them without trusting the page they came from, or us.

Where this fits

Most teams already run something in this space, and usually should. Here is the honest map of what each kind of tool is for, and what continuous signed telemetry adds next to it.

Your registrar and DNS dashboards

What it is good at

Authoritative for the domains inside that one account, and the place you go to make a change.

What DomainDrift adds

One view across every domain you care about no matter who registers or hosts it, a history of what it looked like before, and a signed record of each state.

Uptime and synthetic monitoring

What it is good at

Telling you fast that a site stopped responding, from many locations, with good alerting.

What DomainDrift adds

The layer underneath reachability: which nameservers, mail route, certificate authority and registrar the domain is on, and the moment any of them changes.

Certificate transparency search

What it is good at

Finding every certificate ever issued for a name, straight from the public logs.

What DomainDrift adds

Certificates joined to the rest of the domain’s infrastructure and watched over time, so an issuer change is an alert with context rather than a log entry to notice.

Passive DNS and threat intelligence feeds

What it is good at

Deep historical resolution data and enrichment for investigation work.

What DomainDrift adds

A signed, receipted observation for each reading, and a change feed built around what materially moved rather than raw resolution history.

Attack-surface and asset discovery

What it is good at

Finding the assets you did not know you had, and scoring their exposure.

What DomainDrift adds

Continuous, verifiable telemetry on the assets once you know them, with an evidence trail an auditor can check without trusting either of us.

A script you wrote against a resolver

What it is good at

Exactly what you want, on your schedule, for free.

What DomainDrift adds

The parts that get expensive: a scanned index at scale, corroboration across independent resolvers before a change is believed, signed history, and alerting you did not have to keep alive.

These are categories of tooling, not products, and the pairing is the point: the fastest setups we see run something from one of the rows above alongside a signed record of what the domain layer underneath is doing.

Start with a curl, not a signup

One request returns a real, current preview of the signed record for any domain. A free account opens the complete record, the full history, and monitoring for your first domain.
