Cybercriminals don't target small businesses because they have more valuable data than enterprises. They target them because they're easier to breach. Most SMBs lack dedicated security teams, use outdated software, and rely on passwords that haven't been changed since the Obama administration.

The most common attack vectors for SMBs are phishing emails, compromised credentials, ransomware, and unsecured remote access. Every item on this checklist addresses at least one of these threats.

This is the single highest-impact security measure you can implement today. MFA adds a second verification step (usually a code from your phone) when logging into accounts. It blocks 99.9% of automated credential attacks.

"Password123" is not a password — it's an open door. Yet variations of it appear in nearly every breach database. Your team needs a password manager (1Password, Bitwarden, or LastPass) and a policy that enforces unique, complex passwords for every account.

Unpatched software is the second most exploited vulnerability after stolen credentials. Enable automatic updates for operating systems, browsers, and business applications. For servers and network equipment, establish a monthly patch cycle.

Traditional antivirus is dead. Modern threats require modern protection. Deploy an endpoint detection and response (EDR) solution on every device that touches your network — laptops, desktops, and mobile devices.
