The Essential Cybersecurity Checklist for Small Businesses

Introduction

Cybersecurity isn’t just a big-business issue — small businesses are frequent targets too. Hackers often assume smaller companies have weaker defenses, making them easier to breach. At Doorzy Tech, we help Saskatoon businesses build strong, practical cybersecurity strategies that protect against today’s most common threats.

1. Use Strong Passwords and Multi-Factor Authentication (MFA)

Require employees to use complex passwords and enable MFA for all critical accounts. This adds an essential extra layer of protection and helps prevent unauthorized access even if a password is stolen.

2. Keep Software and Systems Updated

Outdated software is a hacker’s best friend. Regularly update your operating systems, apps, plugins, and antivirus software to close known vulnerabilities before they’re exploited.

3. Back Up Data Regularly

Set up automated backups stored both locally and in the cloud. Test them frequently to make sure your data can be recovered in case of ransomware attacks or system failures.

4. Train Employees on Cyber Awareness

Human error is one of the biggest cybersecurity risks. Train staff to recognize phishing scams, suspicious attachments, and unsafe websites. Make cybersecurity awareness part of your company culture.

5. Secure Your Wi-Fi Networks

Use strong encryption and a unique password for your Wi-Fi network. Keep guest and internal networks separate to reduce the risk of unauthorized access to sensitive information.

6. Install Firewalls and Endpoint Protection

Firewalls and endpoint protection tools act as shields against cyber threats. Ensure every company device — from computers to mobile phones — is equipped with updated security software.

7. Limit Access to Sensitive Data

Not every employee needs access to every file. Implement user roles and permissions so staff can only access what’s necessary for their work.

8. Monitor for Unusual Activity

Use monitoring tools to detect suspicious logins, file changes, or data transfers. Early detection can stop cyber incidents before they escalate.

9. Create a Cybersecurity Response Plan

Have a clear plan for what to do in case of a security breach. Identify who’s responsible, outline steps to contain damage, and communicate effectively to minimize downtime.

10. Work with Trusted IT Experts

Partner with a reliable IT or cybersecurity provider like Doorzy Tech to ensure your systems are secure, monitored, and compliant with best practices. Regular audits and expert guidance keep your defenses strong.

Conclusion

Cybersecurity isn’t a one-time task — it’s an ongoing responsibility. By following this checklist, your small business can protect itself from costly breaches, maintain customer trust, and operate safely in today’s connected world.
