SENTINEL Snapshot

Give us your domain.

Within three business days you get a short written report on what is publicly discoverable about your business right now: your email authentication, your certificates, your website's security headers, who owns your domain, and the forgotten corners most owners never look at.

The cover of a SENTINEL Snapshot report: a dark page with the verdict X of 5 checks need attention

A real report. We ran it on our own domain first.

Five checks. Public records only.

Everything below is readable by anyone with a browser and a terminal. We are not guessing, and we are not scanning you to find it.

01

Email authentication

SPF, DMARC policy, and the DKIM selector your mail provider published.

Anyone can send email that appears to come from your domain right now. This is the finding owners are never told and the one that costs the most when it lands.

02

TLS certificate

Issuer, expiry date, days remaining, and whether the chain actually validates.

An expired or broken certificate is the one failure every single visitor sees, and most of them leave instead of clicking through.

03

Security headers

HSTS, Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy.

Five instructions your site gives the browser, or fails to give. All five are configuration changes, not projects.

04

WHOIS and registration

Registrar, creation date, expiry date, published registrant, privacy protection.

A lapsed domain takes the website, the email, and every saved link with it. It expires once every few years, which is exactly why nobody diarises it.

05

Public DNS

A, AAAA, MX and NS records, plus records that point at nothing.

Dead records are how mail starts disappearing quietly, and how a name your DNS still points at gets claimed by someone else.

Every finding names its own proof.

No finding goes in the report without the record, the header, or the certificate that produced it. Your IT person can reproduce every line with one command.

That single rule is the difference between this and a twenty dollar templated scan that tells you to panic and offers nothing you can hand to a technician.

HighFinding 01

DMARC is set to p=none, observing and not enforcing

What we observed
TXT _dmarc.example.com returns: v=DMARC1; p=none; rua=mailto:reports@example.com
Policy value: p=none.
What this means

You have told the world to watch, not to act. Mail that fails authentication is delivered anyway, so anyone can still send email that appears to come from your business.

Reproduce it
dig TXT _dmarc.example.com
Fix

Once SPF and DKIM are clean for every real sender, move to quarantine, then reject. Two weeks between steps.

We do this free because the report is the argument.

If it comes back clean, you have lost nothing and you know your domain is tighter than most. If it does not, and it usually does not, you will have the evidence in your hand and a list of what to fix first.

One line in that report will be a number: how many of the five checks need attention. Not a score out of a hundred. Not an adjective. A count, with the proof behind it.

Two fields.

Your domain, and where to send the report. That is the entire intake, so there is no step after this one where we ask you for something we should have asked for now.

Only submit a domain you own or are authorized to request a report for. One domain per submission. No sales call follows unless you ask for one.

What this report is not.

Written down because a security report that hides its limits is not worth the paper it is printed on.

  • Not a scan. No port scans, no service probing, no vulnerability scanning.
  • Not authenticated. We never log in to anything you own, and no test email is sent.
  • Not a guarantee. It documents what is publicly visible, and public records cannot see inside your network.
  • Not a snapshot of tomorrow. One point in time, on the date printed on it.
