1. MFA Everywhere

Enable Multi-Factor Authentication (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 playground for hackers.

3. Backup Strategy

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

4. Employee Training

Conduct 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 (IR) Readiness

An effective cybersecurity SME doesn't just plan for success; it plans for recovery. Do you have a written contact list of who to call if you are breached? This includes your IT lead, your insurance agent, and your legal counsel. Having this "Break Glass" plan ready can save hours of critical time during an actual incident.

7. Controlling "Shadow IT"

Every employee who uses their personal Dropbox or an unsanctioned AI tool for work is creating a security hole. Audit the apps your team is using. Consolidate them under a single company login (SSO) to regain control over your data. For a deeper look at this, read our guide on Cloud Security for Startups.
