Top 5 Cybersecurity Mistakes Small Businesses Make

Avoiding these common errors can save your company from a devastating breach.

Introduction

Small businesses often believe they’re “too small” to be targeted by cybercriminals. That assumption can be costly. In reality, attackers often go after smaller companies because they expect less protection — and they’re usually right.

Below are the five most common cybersecurity mistakes that small businesses make — and how to avoid them.

1. Weak or Reused Passwords

Too many companies still rely on weak, simple, or reused passwords across accounts. This leaves doors wide open for attackers using brute force or credential stuffing attacks.

Solution: Use a password manager and implement strong, unique passwords for each account.

2. No Multi-Factor Authentication (MFA)

MFA adds a critical second layer of defense, yet many businesses skip it entirely.

Solution: Enable MFA on all critical systems, especially for email, cloud storage, and financial platforms.

3. Outdated Software and Devices

Running outdated operating systems, browsers, or plugins means vulnerabilities are unpatched — and attackers know how to find them.

Solution: Create a regular update policy and ensure all devices and applications stay current.

4. Lack of Employee Training

Even the best firewall can’t stop an employee from clicking a malicious link if they don’t know better. Phishing and social engineering are top threats.

Solution: Conduct regular cybersecurity awareness training. Employees are your first line of defense.

5. No Backup or Recovery Plan

Cyberattacks like ransomware can destroy or encrypt valuable data. If you don’t have a solid backup plan, recovery could be impossible.

Solution: Set up automated backups (cloud and local), and test your recovery process regularly.

Final Thoughts

Cybersecurity isn’t just for big corporations. A single mistake can lead to financial loss, reputational damage, or legal issues — especially for smaller businesses with fewer resources to recover.
