5 cybersecurity mistakes small Florida businesses keep making in 2026

Every small business owner we talk to eventually says some version of the same thing: “We’re too small to be a target.”

I wish that were true. It hasn’t been for at least a decade, and in 2026 it’s actively dangerous thinking. Attackers today don’t pick targets one at a time — they run automated sweeps across thousands of small businesses at once, looking for the easy ones. Being small doesn’t hide you. Being lazy about five specific things is what makes you the easy one.

Here are those five things, ranked by how often we walk into a Palm Beach County small business and find them.

1. No multi-factor authentication on email

This is the number-one finding, every time. A small business has Microsoft 365 or Google Workspace, MFA is free, and nobody turned it on — or worse, it’s turned on for the owner but not for the bookkeeper, the front desk, or the part-time staffer who answers email on her personal phone.

Why it matters: the moment an attacker gets into one email account, they read every conversation, watch for the next wire transfer, and impersonate you to your vendors. The dollar amounts on the resulting fraud make ransomware look quaint.

Fix this week: turn on MFA for every single user on your email system. Not just admins. Every user. If you don’t know how, ask someone who does — this is not a “maybe next quarter” task.

2. Backups that aren’t actually backups

Second most common. The business has “backups” — usually an external drive plugged into the server, or a copy of files sitting in the same OneDrive everything else lives in. If ransomware hits, the “backup” gets encrypted along with the original. Congratulations, you have a very expensive copy of nothing.

A real backup has three properties. It’s automated, it’s stored somewhere separate (different credentials, different location, not just a different folder), and someone checks regularly that it still works. Most of the “backups” we audit fail at least two of those three tests.

Fix this quarter: verify that your backups would actually restore after a ransomware attack. Ask your IT person to do a test restore — not a theoretical one, a real one where they pull files from the backup onto a different machine. If they can’t, your backup strategy is theatre.

3. Old employees who still have access

Someone left the company eight months ago. Their Microsoft 365 account is still active. Their VPN credentials still work. They’re still on the vendor portal. Maybe they’re a nice person and would never use that access — but when their personal email gets compromised (and it will), the attacker now has a back door into your business.

This mistake compounds. Most small businesses we meet have at least three former employees with active credentials. Sometimes the number is a decade’s worth.

Fix this month: walk your staff list. Anyone who’s not currently getting a paycheck should have every account disabled, every credential rotated, every shared folder reviewed. Make offboarding a checklist, not an afterthought.

4. Treating the receptionist’s computer as untrusted... but not the owner’s

We see this pattern constantly. The owner — the person with access to everything — uses the least-protected computer in the building. Home laptop. No endpoint protection. Works from coffee shops. Clicks every link. Uses the same password everywhere.

Meanwhile, the receptionist’s workstation has full endpoint protection, locked-down admin privileges, and controlled software installs. The threat model is upside down. Attackers know this, and they target the people with access, not the people with defenses.

Fix now: whoever has the most access needs the most protection. Reversed is the default, and the default is wrong.

5. “We have antivirus” as the entire security strategy

Traditional antivirus hasn’t been a complete defense since roughly 2015. Modern attacks don’t depend on signatures that AV can recognize — they use credential theft, social engineering, legitimate tools misused (PowerShell, remote management software), and fileless techniques that don’t trigger traditional scanners at all.

What you actually need in 2026: endpoint detection and response (EDR), which watches behavior, not just file signatures. Phishing-resistant email filtering. A decent password manager enforced across the team. MFA on everything. And someone who will actually look at alerts when they fire — which is most of the battle.

Fix this year: if your cybersecurity strategy is “we have antivirus,” you have one line of defense against attackers who have ten. Talk to someone about a real layered approach before you’re explaining to your clients why their data got stolen.

The uncomfortable truth

Every single one of these mistakes is cheap to fix compared to what happens when you don’t. Ransomware recovery at a small business averages six figures. Business email compromise (BEC) incidents frequently run five figures in misdirected wire transfers. Client data breaches at a law firm or title agency can trigger regulatory penalties that dwarf the ransom itself.

None of the fixes above require enterprise budgets. They require someone to sit down and do the work. If that person isn’t you, hire someone. If the person you already have hasn’t mentioned any of these, that’s telling you something.

Palm Beach County has no shortage of small businesses that learned all five lessons the hard way. You don’t have to be one of them.
