Small businesses are prime targets for cyberattacks. You have valuable data but typically less security than large enterprises. Criminals know this.

The good news: You don’t need a massive budget to significantly improve your security posture. Here are the fundamentals that matter most.

The basics: Your security foundation

Strong passwords and password managers

Weak passwords are still the most common entry point for attackers. Requirements for 2024:

  • Minimum 12 characters (longer is better)
  • Unique for every account (no reuse)
  • Not based on dictionary words or personal info

Nobody can remember unique complex passwords for dozens of accounts. Use a password manager:

  • 1Password – Excellent for business use
  • Bitwarden – Strong free option
  • LastPass – Popular, good business features

A password manager is essential, not optional.

Multi-factor authentication (MFA)

MFA requires something you know (password) plus something you have (phone, security key). Even if passwords are stolen, attackers can’t get in without the second factor.

Enable MFA on:

  • Email (priority one)
  • Microsoft 365 or Google Workspace
  • Banking and financial services
  • VPN and remote access
  • Any system with sensitive data

Best options:

  • Hardware security keys (most secure)
  • Authenticator apps (Microsoft Authenticator, Google Authenticator, Authy)
  • SMS codes (better than nothing, but weaker)

Keep software updated

Most successful attacks exploit known vulnerabilities with available patches. Keeping software updated eliminates these easy wins.

Update priorities:

  • Operating systems (Windows, macOS)
  • Browsers (Chrome, Firefox, Edge)
  • Office applications
  • Business applications
  • Network equipment firmware

Enable automatic updates where possible. Schedule regular manual checks for everything else.

Email security

Email is the primary attack vector for most businesses. Phishing, malware attachments, and business email compromise all start in your inbox.

Recognize phishing attempts

Train yourself and your team to spot:

  • Urgent requests for action
  • Requests for credentials or sensitive information
  • Unusual sender addresses (look closely—subtle misspellings)
  • Unexpected attachments
  • Pressure to bypass normal procedures

When in doubt, verify through a different channel. Call the person directly (using a known number, not one from the suspicious email).

Email security features

Enable available protections:

  • Spam filtering (usually on by default)
  • Malware scanning (scan attachments automatically)
  • Link protection (check links for known malicious sites)
  • Impersonation protection (flag emails that appear to be from executives but aren’t)

Microsoft 365 Business Premium includes these features. Make sure they’re configured.

Network security

Firewall basics

Your network should have a firewall controlling what traffic enters and exits. Most business routers include basic firewall functionality.

Check that:

  • Default deny for inbound connections
  • Remote management is disabled or secured
  • Firmware is current
  • Default passwords are changed

Wi-Fi security

  • Use WPA3 or WPA2 (never WEP)
  • Strong, unique WiFi password
  • Guest network for visitors
  • Consider separate networks for IoT devices

VPN for remote access

If employees access company resources remotely, use a VPN. Don’t expose internal systems directly to the internet.

Endpoint security

Antivirus/anti-malware

Modern endpoint protection goes beyond traditional antivirus:

  • Windows Security (Defender) is actually good now for basic protection
  • Microsoft Defender for Business adds cloud-based protection and management
  • Third-party options like SentinelOne, CrowdStrike offer advanced protection

Ensure every device has protection installed, enabled, and updating.

Device encryption

Full-disk encryption protects data if devices are lost or stolen:

  • Windows: BitLocker (built into Pro and Enterprise)
  • macOS: FileVault (built in)

Enable encryption on all business devices.

Backup as security

Ransomware makes backups a security measure, not just a convenience. If you can restore from clean backups, you don’t need to pay ransoms.

Backup requirements for security:

  • At least one backup offline or immutable (attackers can’t encrypt it)
  • Tested restore capability
  • Backup systems use different credentials than production
  • Regular backup verification

Training your team

Technology only goes so far. People are often the weakest link.

Essential training topics:

  • Recognizing phishing emails
  • Password best practices
  • Safe browsing habits
  • Reporting suspicious activity
  • Physical security awareness

Training doesn’t need to be expensive. Short, regular reminders are more effective than annual hour-long sessions.

Incident response

Know what to do when something goes wrong:

  1. Detect – Know the signs of compromise
  2. Contain – Isolate affected systems
  3. Assess – Understand what happened
  4. Recover – Restore from clean backups
  5. Report – Notify appropriate parties (legal, regulatory, law enforcement)
  6. Learn – Improve defenses based on lessons learned

Have contact information ready: IT support, legal counsel, cyber insurance provider, law enforcement.

Getting started

If you’re overwhelmed, start here:

  1. Password manager – Get everyone using one
  2. MFA on email – Enable today
  3. Updates – Enable automatic updates everywhere
  4. Backups – Verify they exist and test a restore
  5. Phishing awareness – Talk to your team
