Years of history the moment you start.

A record that starts empty is a promise. We read what is already public, so day one arrives with lineage rather than a counter at zero and a wait.

Every certificate ever issued

Certificate transparency logs are public and complete. We read them at signup, so you get the full lineage back to 2019 or earlier, with every issuer change dated.

How long you have held it

Registration date, registrar history and current status, straight from the registry. Held for nine years is a fact you can state on your first afternoon.

The full inventory

Every subdomain resolving, every third-party script loading, every DNS record, your certificate authority policy and your mail posture. Written down, most of it for the first time.

One thing we will not do

Your record says one day on day one.

  • The history above is public. We found it, we did not watch it, and we label it that way
  • The verified record begins the day you do and cannot be backdated by any mechanism
  • Ours said one day too, and it is linked at the bottom of every page
  • That is inconvenient now and it is the entire value in three years
See our own record

The limit of any check

Domains and certificates expire. Yours will not.

That is the position today. Nothing above shows what was true last year, and nothing can be reconstructed later.

Every checker tells you where things stand right now and then forgets you were there. The questions that come up later are different ones. When did this change. What was it before. How long has any of it actually been watched.

Three things, and nothing to set up.

One domain is the only input. Everything after that happens without you, and arrives as an email.

Identify

One domain builds the inventory. Registrar and renewal date, certificate and coverage, mail provider and authentication, hosting, embedded services, and every subdomain still resolving.

Watch

Checks continue on a schedule with no further input. A weekly email confirms the position. Anything urgent, such as an approaching expiry or broken mail authentication, reaches you immediately.

Keep

Every check is timestamped and sealed so it cannot be revised later. You can see the position on any past date, along with the values that came before each change.

The published record

One link for anyone who asks you to prove it.

Issued the day you start. It answers client questions, insurance enquiries and vendor reviews without anyone assembling paperwork, and it states plainly how long the position has held without a break.

This is an illustration of what a record looks like after three years, not a customer. Nothing here can be backdated, which is the whole point — so our own record shows the real number, counting from the day we started.

How this is different

Most tools report today. This one keeps it.

Checking a domain is a commodity. MxToolbox, EasyDMARC and several others do it free, and your registrar already sends renewal notices. That part is well covered and we are not claiming to do it better.

What none of them keep is the history. When was the host changed. What was the value before someone edited it. How long has this been watched. Those questions come up during audits, handovers, insurance claims and sales, and a record that was never running cannot answer them.

Every check here is timestamped and sealed. After a year you can produce any date. After three years, continuity itself is the evidence, and that is the one thing no competitor can hand a new customer no matter what they build.

If an expiry alert is all you need, the free tools do that well and you should use them. This is for the moment someone asks you to prove it.

Two situations, one service

A domain is a domain, whoever owns it.

When nobody is looking after it

The domain lapses and the site goes dark. The certificate expires and browsers turn visitors away. Email stops arriving and you assume people are not replying. None of it announces itself, so the first you hear is usually from a customer.

When several people half are

Certificates issued by someone who left. Domains on a personal card. Mail authentication broken by a DNS change nobody wrote down. The record shows what changed and when, which otherwise takes days to piece together.

Start the clock today.

The record is worth more the longer it runs, and there is no way to get back a month you did not keep.

Questions

The things people ask before signing up.

Do I need to change anything on my domain to use this?

No. You type your domain and that is the whole setup. There is no DNS record to add, no code to install, no account to connect and no password to hand over. Everything we read is public information about the domain, of the kind anyone can look up.

My registrar already emails me about renewals. Why pay for this?

They do, and if that email reaches the right person you are covered on that one item. The problems are that the notice goes to whoever registered the domain, which is often somebody who has left, and that it covers only the registration. Your certificate, your mail records and your subdomains are not on anybody's reminder list. Beyond that, a notice is not a record. It tells you what to do this month, not what was true two years ago.

What is the difference between this and a free domain checker?

The check itself is much the same, which is why we give ours away too. The difference is that a checker forgets you the moment you close the tab. Run it again next year and it starts from nothing. We keep every check, dated and sealed, so the history exists when somebody asks for it.

How often will I actually hear from you?

Once a week, most weeks saying nothing broke. Urgent items arrive immediately and separately, and in a normal year there are only a handful of those. If you are hearing from us often, something is genuinely wrong.

I am not technical. Will the alerts make sense to me?

They are written for somebody who does not know the terminology. An alert says your email can currently be impersonated rather than quoting a policy string, and every finding links to instructions written the same way, with the technical detail below for whoever needs it. Plenty of customers forward the email to whoever built their site and that works fine.

What happens to my record if I cancel?

It stops where your payment stops, and the published page shows the gap rather than hiding it. That is what makes continuous verification mean anything. You can export everything before you go, and it stays readable for thirty days at no charge.

Can I try it before paying?

The check is free and unlimited without an account, so you can see exactly what we find on your domain before deciding anything. There is no free monitoring tier, because watching something for free and then stopping would leave a gap in the one thing that is supposed to be continuous.

Is this useful if I look after domains for other people?

It is the most common way it gets used. Portfolio plans put every client domain in one list sorted by what is due, send one weekly email across all of them, and give each client their own published record you can hand over during onboarding.
