5 cybersecurity myths that get small businesses breached

The most expensive thing in security isn't a tool. It's a comfortable assumption. Here are the five we hear most from small businesses, and the real numbers behind why each one is wrong.

1. "We're too small to be a target"

This is the big one, and it's backwards. Attackers don't hand-pick victims. They automate. Bots scan the entire internet for exposed services, weak logins, and unpatched software, then hit whatever answers. Small businesses make up 43% of data-breach victims in Verizon's DBIR, and employees at small firms see roughly 350% more social-engineering attacks than those at large enterprises (Barracuda, 2022). You're not too small to be noticed; you're the path of least resistance.

2. "We have antivirus, so we're covered"

Antivirus catches known malware, but that's not how most businesses get breached anymore. Today it's stolen logins, phishing, and reused passwords. The single most effective fix is multi-factor authentication: Microsoft reports MFA blocks over 99.9% of account-compromise attacks. Yet only about a third of small businesses worldwide use it (Cyber Readiness Institute, 2024). Antivirus is table stakes; it is not a strategy.

3. "Real security is too expensive for us"

The math runs the other way. The median small-business cyberattack costs about $8,300 (Hiscox, 2023), and a full data breach averages $4.88M globally (IBM Cost of a Data Breach, 2024). Meanwhile, the controls that stop most attacks, MFA, automatic patching, tested backups, a password manager, cost little to nothing. Prevention is the cheap part. The breach is the expensive part.

4. "Nobody wants our data"

They don't want your data. They want a ransom, your bank access, and your computing power. 88% of small-business breaches involved ransomware in Verizon's 2025 DBIR, far above the rate at large organizations. Ransomware doesn't care what industry you're in; it encrypts whatever it can reach and demands payment. If you have a bank account and computers that turn on, you have something worth attacking.

5. "We passed our audit, so we're secure"

Compliance is a point-in-time checkbox. It proves you met a standard on the day of the audit, not that an attacker can't get in tomorrow. Attackers don't read your audit report. "Secure" means proven closed today: find the gap, fix it, and re-test to confirm it's actually shut. That's a different exercise than passing a questionnaire, and it's the one that keeps you out of the headlines.
