Start With These Five Priorities

If you cannot address everything at once, start with the security improvements that can reduce some of the most common risks:

1. Use a business password manager.
2. Enable multi-factor authentication on important accounts.
3. Keep devices and software updated.
4. Maintain reliable, tested backups.
5. Train employees to recognize phishing attempts.

Small improvements across these areas can significantly strengthen the security of a small business without requiring an enterprise-level cybersecurity program.
