Cyberattacks on small businesses have increased dramatically over the past few years. According to recent studies, 43% of cyberattacks target small businesses, yet only 14% are prepared to defend themselves. The good news? You don't need an enterprise budget to implement effective security measures.

1. Enable Multi-Factor Authentication (MFA) Everywhere

Multi-factor authentication adds an extra layer of security beyond just a password. Even if an attacker obtains a password through phishing or a data breach, they still can't access your accounts without the second factor.

Start with the most critical accounts first:

  • Email accounts — The keys to your kingdom. Most password resets go through email.
  • Banking and financial — Direct access to your money.
  • Cloud services — Microsoft 365, Google Workspace, etc.
  • Business applications — CRM, accounting software, project management.

Use authenticator apps (Microsoft Authenticator, Google Authenticator) rather than SMS when possible. SMS can be intercepted through SIM swapping attacks.

2. Train Your Employees on Phishing

The most sophisticated firewall in the world won't help if an employee clicks a malicious link or opens an infected attachment. Phishing remains the #1 attack vector for small businesses because it exploits human nature, not technology.

Effective training should cover:

  • How to identify suspicious emails (urgency, unusual requests, misspellings)
  • Verifying requests through a separate channel before acting
  • Safe browsing habits and recognizing fake websites
  • What to do if they accidentally click something suspicious

Consider running simulated phishing tests quarterly. This gives your team practice in a safe environment and helps you identify who needs additional training.

3. Implement a Solid Backup Strategy

Ransomware attacks continue to devastate small businesses. The best defense against ransomware? A backup strategy that allows you to recover without paying the ransom.

Follow the 3-2-1 rule:

  • 3 copies of your important data
  • 2 different types of storage media
  • 1 copy offsite or in the cloud

Critically important: test your backups regularly. A backup you've never tested is a backup that might not work when you need it most.

4. Keep Software Updated

Software updates often include patches for known security vulnerabilities. Delaying updates leaves your systems exposed to attacks that have publicly documented exploits.

Set up automatic updates where possible, especially for:

  • Operating systems (Windows, macOS)
  • Web browsers
  • Office applications
  • Security software

For business-critical applications where automatic updates might cause disruption, establish a regular patching schedule — ideally within 48 hours of security patches being released.

5. Use Business-Grade Security Tools

Consumer-grade antivirus software isn't designed for business environments. Invest in proper endpoint detection and response (EDR) solutions that provide:

  • Real-time threat detection across all devices
  • Centralized management and reporting
  • Automated response to detected threats
  • Visibility into what's happening across your network

Pair this with a properly configured firewall and email filtering to create multiple layers of defense.

Getting Started

You don't have to implement everything at once. Prioritize based on your biggest risks. For most small businesses, that means starting with MFA and employee training — they address the most common attack vectors.

If you're not sure where your security gaps are, start with an assessment. Understanding your current state makes it much easier to prioritize improvements that will actually make a difference.
