Covering the security basics protects you from 90% of common threats. Work through this list.

1. MFA everywhere

Enable MFA on email, banking, and cloud storage. This is the single most effective step you can take.

2. Update software

Enable automatic updates for your OS and antivirus software. Unpatched software is a common entry point.

3. Backup strategy

Use the 3-2-1 backup rule: 3 copies of data, on 2 different media, with 1 offsite (cloud). Test your backups monthly.

4. Employee training

Run phishing simulations quarterly. Your employees are your first line of defense.

5. Secure Wi-Fi

Separate guest Wi-Fi from internal business networks. Use WPA3 encryption.

6. Incident response readiness

Do you have a written contact list of who to call if you're breached? Your IT lead, insurance agent, and legal counsel. Having that list ready before something happens saves critical time.

7. Controlling shadow IT

Employees using personal Dropbox accounts or unsanctioned AI tools for work create security gaps. Audit the apps your team uses. Consolidate them under a company login (SSO) to get control of your data back. For a deeper look, read our guide on Cloud Security for Startups.
