Cybersecurity Basics Every Small Business Should Have in Place

Most successful attacks on small businesses don't involve sophisticated hacking — they exploit a handful of well-known gaps. Closing these five doesn't require a big budget, just consistency.

1. Multi-factor authentication (MFA) everywhere

A stolen password alone shouldn't be enough to get into your email, accounting software, or cloud storage. MFA is the single highest-impact control most businesses can add, and it's usually free to turn on.

2. A password manager for the whole team

Reused and weak passwords are still one of the most common ways accounts get compromised. A shared password manager makes strong, unique passwords the easy option instead of the annoying one.

3. Managed firewall and endpoint protection

A firewall controls what can reach your network; endpoint protection watches individual devices for suspicious activity. Together, they cover both the perimeter and the device level — you need both, not one or the other.

4. Regular employee security awareness training

Most breaches start with a convincing email, not a broken firewall. Short, regular training — not a once-a-year slideshow — measurably reduces how often people click on phishing attempts.

5. Backups that follow the 3-2-1 rule

Three copies of your data, on two different types of storage, with one copy off-site. If ransomware hits, a tested backup is often the difference between a bad afternoon and a business-ending event.

Where to start

If you only do one thing this month, turn on MFA for email and any system that touches money. It's the fastest way to close the most commonly exploited gap.
