5 Cybersecurity Mistakes Small Businesses Make (And How to Fix Them)

The Uncomfortable Truth

Most small business owners assume a cyberattack won't happen to them. They're wrong — and the statistics back it up. 43% of cyberattacks target small businesses, and 60% of those businesses close within six months of a significant breach.

The good news: most of these attacks exploit preventable vulnerabilities. Here are the five we see most often.

1. Weak or Reused Passwords

This is still the number one attack vector. Employees reuse the same password across personal and work accounts. One breach somewhere else becomes a breach everywhere.

What to do: Deploy a password manager (1Password, Bitwarden, or Keeper work well for small teams) and require unique passwords for every business account. Pair this with multi-factor authentication (MFA) on email, banking, and any system with sensitive data.

2. No MFA on Email

Email is the master key to your digital life. With access to your email, an attacker can reset every other password you own.

What to do: Enable MFA on your email provider today. Google Workspace and Microsoft 365 both make this straightforward. This single step blocks over 99% of automated account takeover attempts.

3. Employees Who Haven't Been Trained on Phishing

Phishing emails are the delivery mechanism for most ransomware and credential theft. They're getting harder to spot — AI is now being used to craft convincing, personalized attacks.

What to do: Run a phishing simulation with your team once a quarter. Free tools exist for this. The goal isn't to embarrass people — it's to build awareness before an attacker tests them first.

4. Outdated Software

Every unpatched piece of software is a potential door into your network. Attackers actively scan for businesses running known-vulnerable versions of common software.

What to do: Enable automatic updates on operating systems and applications. For servers and network equipment, establish a monthly patching routine.

5. No Backups (or Untested Backups)

Ransomware is effective because it encrypts your data and demands payment to restore it. The counter to ransomware is a reliable, tested backup.

What to do: Follow the 3-2-1 rule — 3 copies of your data, on 2 different media types, with 1 copy offsite (cloud counts). Most importantly: test restoring from your backup at least once a year.

Where to Start

If this list feels overwhelming, start with items 1 and 2. MFA on email and a password manager will eliminate the majority of your risk with minimal effort and cost.
