The Cybersecurity Threats Small Businesses Actually Face

· WITTCO

Security news tends to cover the dramatic stuff: state-sponsored hackers, brand-new exploits, breaches with names like heavy metal albums. That isn't what usually happens to a small business in Metairie or Mobile.

What usually happens is dull. That's good news, because dull problems have well-known fixes. Here's what shows up for small offices, and what stops each one.

Fake login pages

Phishing is still how most attacks start. An email asks someone to sign in: a shared document, a voicemail notice, an e-signature request, a warning that the mailbox is full. The link goes to a page that looks exactly like the Microsoft 365 or Google sign-in screen. Someone types their password, and now an attacker has it.

What helps: multi-factor authentication on every email account, with no exception for the owner. Email filtering that catches known bad links before they reach an inbox. And phishing simulations, where your team gets realistic fake phishing emails and learns to spot them somewhere a mistake costs nothing.

Invoice and payment fraud

Once someone is inside an email account, they rarely do anything loud. They read. They learn who you pay, when, and how those emails are usually worded. Then, at the right moment, a message goes out asking for payment to "our new bank account."

Law offices, title companies and contractors get targeted because they move large sums by wire. A law office in Mandeville handling real estate closings is exactly who this scam is built for.

What helps: a firm rule that any change to payment details gets confirmed by calling a number you already have, never the one in the email. Multi-factor authentication, again. And alerts for odd mailbox activity, like a new rule that quietly forwards mail to an outside address.

Ransomware

Ransomware encrypts your files and demands payment for the key. These days it often comes with a second threat: pay, or we publish what we copied.

Picture a family medical practice in Slidell on a Monday morning. The scheduling system, the patient records and every shared file are locked. Nobody is seeing patients until that's fixed.

What helps: endpoint protection that recognizes ransomware behavior and can stop it mid-attack (that's what SentinelOne is for), plus backups kept somewhere an attacker inside your network can't reach or delete. And test the restore. A ransomware attack is the worst possible time to learn your backup doesn't work.

Old computers and skipped updates

Attackers love old software because its holes are already public. Windows 10 stopped getting regular security updates in October 2025, and plenty of those machines are still running in back offices, usually the one computer with the old accounting program nobody wants to touch.

What helps: patching on a schedule, with someone confirming it actually happened. A budget for replacing hardware before it ages out. And if one old machine truly has to stay, keep it off the internet and away from everything else.

Accounts nobody turned off

The receptionist who left in 2023 may still have a working email login. So might the bookkeeper before your current one. Shared passwords make it worse: when five people know the password to one account, you can't lock out one of them without locking out all five.

What helps: one login per person, removed the day they leave, and a business password manager, so shared access doesn't live on a sticky note stuck to somebody's monitor.

What gets more attention than it deserves

Yes, criminals use AI. Mostly they use it to write better phishing emails, which means the old advice to watch for bad grammar is out of date. Some fake emails now read better than the real ones. The defense hasn't changed: verify requests another way, and use MFA so a stolen password isn't enough.

Smart TVs, cameras and other connected gadgets carry real risk too, but the fix is simple. Put them on their own network, away from the computers that hold your data, and change the default passwords.

None of this takes a big security team. It takes the basics, done every time, by someone who's paying attention.
