Cybersecurity Best Practices for Small Businesses

Small businesses are attractive targets precisely because attackers assume they are unprotected. The good news: the majority of incidents exploit basic gaps that are cheap to close. Work through this checklist and you will be ahead of most companies your size.

Use a password manager and two-factor authentication

Reused passwords are the number-one way accounts get compromised. A password manager generates unique credentials for every service, and two-factor authentication (2FA) blocks attackers even when a password leaks. Turn 2FA on for email, banking, hosting and social media first.

Keep software updated

Operating systems, browsers, plugins and content management systems all receive security patches. Enable automatic updates where possible and schedule a monthly check for everything else — including your WordPress themes and plugins.

Back up, then test the backup

Ransomware is survivable when you have clean, recent backups stored somewhere the attacker cannot reach. Follow the 3-2-1 rule: three copies, two media types, one off-site. Restore a file once a quarter to prove it works.

Train your team

Phishing emails remain the most common entry point. Short, regular reminders — check the sender, hover over links, never share codes — dramatically reduce risk.

Secure your website

• Use HTTPS everywhere and renew certificates automatically.
• Limit admin accounts and use strong, unique passwords.
• Install a web application firewall and keep an eye on login attempts.
• Delete unused plugins and themes.

Security is a habit, not a product. A few consistent practices protect your data, your customers and your reputation.
