See your business the way an attacker does — in about ten seconds

Most small-business owners assume they're too small to be worth attacking. That's true — and it doesn't help, because attackers stopped choosing targets years ago. They run automated tools that sweep the entire internet looking for one thing: a misconfiguration. An email domain that can be impersonated, a remote-desktop port left open, a setting nobody's checked since the company was set up. The bot that finds it neither knows nor cares whether it belongs to a ten-person firm or a Fortune 500. To a scanner, you're not small — you're an address, and the only question is whether something is open.

Here's what those sweeps read about your business, right now, from public records:

Can I send email that looks like it's from you? If your domain's email protections — SPF and DMARC, in the jargon — are missing or set loosely, anyone can send email as your company: the fake invoice to your customer, the "urgent payment" request to your bookkeeper.

Is the domain itself loose? Public registration records show when your domain expires and whether it's locked against transfer. Let it lapse and whoever picks it up gets your website and your email.

What have you left open to the internet? Services like Shodan continuously index everything facing the internet. A forgotten remote-desktop connection or an open database shows up there, already labeled — which is how a lot of ransomware incidents at small companies begin.

You don't have to be chosen to be found. You just have to have something showing.

Check yourself in ten seconds

The free scan above shows you the same view the sweeps get. Type your domain, and about ten seconds later you'll see what's visible from the outside, with every finding in plain English: what it means, what an attacker would do with it, and how to fix it. No account, nothing to install — and it only reads public records. No scanning of your systems, no sign-in attempts.

We ran it on our own domain first. It found a real gap in our email setup, and we fixed it the same day.

One honest caveat

For most small businesses, the biggest risks aren't outside — they're inside: staff signing in without multi-factor authentication, old admin accounts, guest access nobody reviews. The free scan can't see any of that. The inside view is what Tenant Strike checks with a read-only connection to Microsoft 365. But the outside view is the part you can check right now, for free.

If the scan comes back clean, that's ten seconds well spent. If it doesn't, most fixes take minutes: turn on email spoofing protection, lock your domain, close what shouldn't be open. Each one takes a standard move away from whoever looks your business up next.
