10 Common Cybersecurity Mistakes Businesses Make and How to Avoid Them

Cybersecurity mistakes can have devastating effects on businesses of all sizes. Whether you’re a startup or an established company, failing to address vulnerabilities can lead to data breaches, financial losses, and reputational damage. 

Below, we explore some of the most common cybersecurity mistakes small businesses make, along with actionable tips to help you protect your organization.

1. Failing to Update Software Regularly

Hackers can get access to your systems by taking advantage of security flaws caused by outdated software. One of the most important cybersecurity errors to correct is the widespread practice of corporations delaying updates while frequently underestimating the threats.

How to Avoid It:

  • Turn on automatic updates for Microsoft Office 365, business tools, and operating systems.
  • Conduct regular IT audits to ensure all software, including those hosted on cloud solutions like Microsoft Azure, is up to date.

2. Weak Password Practices

Weak or reused passwords are a leading cause of data breaches, giving cybercriminals easy access to sensitive information. In the 2021 Colonial Pipeline ransomware attack, for instance, attackers used a hacked password without MFA to obtain access, causing petroleum supplies to be disrupted throughout the United States. Without multi-factor authentication (MFA), even strong passwords can be compromised. 

How to Avoid It:

  • Enforce password policies requiring complexity, length, and regular updates.
  • Use MFA and password management tools to protect critical systems like IT services and cloud platforms.

3. Lack of Employee Training

Employees often fall prey to phishing attacks or other social engineering tactics due to a lack of awareness. This makes human error one of the most common cybersecurity mistakes startup businesses must avoid to minimize risks. For instance, in 2019, a phishing attack targeted City of Saskatoon personnel, causing them to unintentionally send money to scammers, resulting in a $1 million loss.

How to Avoid It:

  • Train employees regularly on recognizing cyber threats and best practices for avoiding them.
  • Incorporate phishing simulations and provide clear steps for reporting suspicious activity.

4. Insufficient Backup Practices

Without frequent and secure backups, businesses risk losing critical data permanently after a ransomware attack or system failure. Backup issues are particularly problematic for small businesses, where data loss can halt operations entirely.

How to Avoid It:

  • Automate backups using secure cloud solutions like Microsoft Azure to ensure consistent data protection.
  • Test backup systems regularly to confirm data can be restored quickly and reliably when needed.

5. Neglecting Endpoint Security

Endpoints like laptops and cell phones have been popular targets for hackers as remote work has grown in popularity. Unsecured devices give hackers access points, endangering entire networks. 

For instance, a ransomware assault on the software company Blackbaud during the 2020 shift to remote work compromised critical data from multiple enterprises by taking advantage of unprotected endpoints.

How to Avoid It:

  • Deploy endpoint protection tools across all devices accessing your systems.
  • Enforce secure remote access using VPNs and comprehensive IT services solutions.

6. Overlooking Insider Threats

Insider threats, whether from disgruntled employees or accidental errors, can lead to data breaches and financial losses. Neglecting to monitor employee activity leaves organizations unaware of these potential risks.

How to Avoid It:

  • Restrict access to sensitive data based on employee roles and responsibilities.
  • Use cloud solutions to track and monitor user activity for suspicious behaviour.

7. Ignoring Small Business Security

Attacks target small businesses because they believe they are too tiny to be targeted. Small firms frequently make this cybersecurity error because cybercriminals are aware that they usually have fewer defenses.

How to Avoid It:

  • Invest in scalable IT services, such as intrusion detection systems, firewalls, and antivirus programs. 
  • Partner with managed service providers (MSPs) for professional-grade security support tailored to SMEs.

8. Lack of Incident Response Planning

When a cyberattack occurs, businesses without a response plan often panic, leading to delayed containment and increased damages. Without drills or preparation, teams struggle to coordinate an effective response.

How to Avoid It:

  • Create an incident response plan detailing steps for containment, investigation, and recovery.
  • Regularly test your response plan through simulations and use cloud solutions.

9. Over-reliance on Legacy Systems

Legacy systems often lack modern security features, leaving businesses exposed to advanced threats. While cost-cutting may seem appealing, this is a cybersecurity mistake startup businesses must avoid to ensure long-term safety. For example, the 2017 WannaCry ransomware outbreak affected over 200,000 machines globally by making use of flaws in out-of-date Windows operating systems.

How to Avoid It:

  • Upgrade outdated systems and migrate to secure solutions. You can buy Microsoft Office 365 in Toronto for modern tools and collaboration.
  • Isolate legacy systems with network segmentation until a replacement can be implemented.

10. Failing to Comply with Security Regulations

Non-compliance with regulations like Canada’s PIPEDA can result in fines, legal issues, and reputational damage. Businesses that overlook compliance also risk exposing customer data to breaches.

How to Avoid It:

  • Review your cybersecurity policies regularly to ensure compliance with laws and industry standards.
  • Use tools within Microsoft Azure to monitor and manage data security and compliance protocols effectively.

Addressing these common cybersecurity mistakes is critical for businesses aiming to protect their systems, data, and customers. From software updates to employee training, taking proactive steps can significantly reduce risks.
