Cyberattacks are no longer just a “big company problem.” Today, small businesses are one of the most common targets, often because attackers know security resources are limited or overlooked.
At Wilmot Computer Solutions, we regularly help local businesses recover from preventable security incidents. Below are the top 7 cybersecurity mistakes small businesses make—and how to avoid them before they become costly problems.
1. Thinking “We’re Too Small to Be a Target”
This is the most dangerous misconception.
Hackers don’t care about company size—they care about easy access. Small businesses often lack layered security, making them attractive targets for ransomware, phishing, and data theft.
Reality: Automated attacks scan thousands of businesses daily. If your defenses are weak, size doesn’t matter.
2. Weak or Reused Passwords
Using simple passwords—or the same password across multiple systems—is an open invitation for attackers.
Common problems we see:
-
Shared passwords among employees
-
No password expiration policies
-
No multi-factor authentication (MFA)
Fix: Strong, unique passwords combined with MFA dramatically reduce account compromise.
3. Skipping Software and Security Updates
Outdated systems are one of the easiest ways attackers gain access. Unpatched software often contains known vulnerabilities that criminals actively exploit.
This includes:
-
Windows and macOS updates
-
Third-party apps (QuickBooks, browsers, plugins)
-
Network devices like routers and firewalls
Fix: Automated patch management ensures updates are applied consistently without disrupting work.
4. No Employee Security Training
Employees are frequently the first line of defense—and the first point of failure.
Phishing emails, fake invoices, and malicious links are becoming harder to spot. Without training, even well-meaning employees can accidentally expose your business.
Fix: Ongoing cybersecurity awareness training helps staff recognize threats before clicking.
5. Inadequate or Unverified Backups
Many businesses believe they’re backed up—until they need to restore data and discover the backups don’t work.
Common backup mistakes:
-
No offsite or cloud backups
-
Backups not tested regularly
-
Ransomware encrypting backups too
Fix: Verified, monitored backups with multiple recovery points protect against ransomware and hardware failure.
6. No Antivirus or Endpoint Protection (or Free Versions Only)
Free antivirus software is not designed for business threats. Modern attacks require advanced endpoint detection and response (EDR) to stop suspicious behavior in real time.
Fix: Business-grade security tools monitor activity, isolate threats, and provide visibility across all devices.
7. Lacking a Cybersecurity Plan or IT Partner
Many small businesses operate reactively—calling for help only after something breaks or data is lost.
Without a plan, incidents lead to:
-
Longer downtime
-
Higher recovery costs
-
Lost trust from customers
Fix: A proactive IT strategy with a trusted MSP ensures monitoring, prevention, and fast response.
