10 Common IT Mistakes Small Businesses Make

1. Skipping multi-factor authentication

MFA blocks more than 99% of automated account takeover attempts. Enable it on every Microsoft 365 and Google account today.

2. Using personal email or consumer cloud accounts

Personal Gmail, Hotmail, and consumer OneDrive accounts have no business-grade security, audit logging, or data ownership controls. Move to Microsoft 365 Business Standard or higher.

3. No real backups of Microsoft 365

Microsoft 365 is not backed up by Microsoft. A deleted mailbox or ransomware-encrypted OneDrive can disappear permanently. Add third-party Microsoft 365 backup.

4. Letting Windows go unpatched

Most ransomware exploits vulnerabilities that were patched months earlier. Centralized patch management closes this gap automatically.

5. Sharing admin accounts among staff

Shared logins make it impossible to audit who did what. Every user needs an individual account, and admin accounts should be separate from daily-use accounts.

6. Consumer-grade Wi-Fi and firewalls

Big-box-store routers don't deliver the threat prevention, segmentation, or logging a business needs. Use a business-class firewall with active security licensing.

7. No documented IT inventory

When equipment fails, recovery is dramatically faster if you already have a documented list of devices, software, licences, and vendor contacts.

8. Ignoring staff cybersecurity training

Email is still the number-one attack vector. Quarterly phishing simulations and short training videos measurably reduce click rates.

9. Relying on one person who "handles the computers"

When that staff member is sick, on vacation, or leaves, your business is exposed. Even small businesses benefit from a managed IT partner as backup.

10. Reacting instead of planning

Break-fix IT is always more expensive than proactive management. A modest monthly investment in managed services typically pays for itself in avoided downtime and emergency labour within the first year.
