Why attackers love small businesses (it's not the size of the payout)

There's a comforting story small business owners tell themselves: we're too small to be worth an attacker's time. It feels reasonable. A criminal who could be going after a bank or a Fortune 500 wouldn't bother with a 15-person firm, right?

In 2026, that story is backwards. Small businesses aren't targeted despite being small — for a lot of attacks, they're targeted because of it. And the reason has nothing to do with the size of the payout.

Attackers don't pick you. Their tools do.

The mental image of a hacker hand-picking a victim is mostly fiction. Modern attacks are industrial. Automated tools scan the entire internet around the clock, looking for one thing: something exposed and unprotected. A login page with no multi-factor authentication. A remote-access port left open. A piece of software with a known, unpatched flaw.

The tool doesn't know or care whether you're a hospital or a hair salon. It knows you have an open door. Then a human (or another tool) shows up to walk through it.

So the real question isn't "are we big enough to be worth it?" It's "do we look like an open door?" And small businesses, on average, look like open doors more often — not because owners don't care, but because they rarely have a dedicated security person watching the dozens of settings that matter.

The economics work against you

Here's the uncomfortable part. A large enterprise has a security team, monitoring tools, and an incident-response plan. Breaking in is expensive and the odds of getting caught early are high.

A small business often has none of that. The break-in is cheap, fast, and quiet — and the victim is more likely to pay a ransom because they can't afford the downtime and don't have backups they've actually tested. Attackers have run the numbers. A pile of small, soft targets can be more profitable per hour than one hard one.

Three things that actually move the needle

You can't out-spend a Fortune 500 security budget, and you don't need to. The same automated tools that find you also give up quickly when the easy doors are shut. The goal isn't to be impenetrable — it's to not be the open door the tool was looking for.

1. Turn on multi-factor authentication everywhere — and close the old paths that skip it. This one control stops the large majority of "stolen password" attacks. The gap that catches people is leaving older sign-in methods enabled that ignore it.

1. Shrink what's exposed to the internet. Every open remote-access port, forgotten test server, or public file share is a door. You can't protect what you don't know is out there — so the first step is simply seeing your business the way those scanning tools do.

1. Know your settings, and check them on a schedule. Security isn't a one-time project. Settings drift, people leave, new apps get connected. A quick recurring check catches the door that got propped open last month.

The honest takeaway

Being small doesn't make you invisible — it often makes you efficient to attack. The good news is that the fixes are mostly settings, not budget. The hard part is knowing which doors are open right now.

That's exactly what Tenant Strike checks: it looks at your Microsoft 365 and Azure the way an attacker's scanner would, in read-only mode, and tells you in plain English which doors are open and how to shut them. No security background required — just a five-minute scan to find out where you stand.
