Small businesses are not too small to be targeted by cybercriminals. In fact, small businesses represent a disproportionate share of successful cyberattacks precisely because attackers know their defenses are weaker. The good news is that basic cybersecurity hygiene—inexpensive to implement—defeats the vast majority of attacks.
Multi-Factor Authentication Everywhere
Multi-factor authentication (MFA) is the single highest-impact security control available to small businesses. Enable it on every business account—email, banking, payroll, accounting software, cloud storage—and enforce it for all employees. MFA defeats phishing attacks and credential stuffing even when passwords are compromised.
Regular Backups, Tested Regularly
Ransomware attacks—where criminals encrypt your data and demand payment for the decryption key—are the most devastating attack for small businesses. The defense is a current, working backup. Back up all critical data daily, store at least one copy off-site or in cloud storage, and test restoration quarterly to confirm the backups actually work.
Key Takeaways
- MFA is the highest-impact single security control—enable it on every business account.
- Daily backups with off-site or cloud copies and quarterly restoration tests defeat ransomware.
- Phishing training for all employees (including yourself) prevents most successful attacks.
