3 Security Mistakes Most SMEs Are Making

Unfortunately, many small and medium-sized businesses often overlook or underestimate the importance of robust cybersecurity measures, leaving them vulnerable to cyberattacks. In fact, SMEs are increasingly becoming the target of cybercriminals because they typically have weaker defenses than large corporations. This blog will explore three massive cybersecurity mistakes that most SMEs are making and how you can avoid them.

For SMEs, navigating the complexities of cybersecurity can feel overwhelming, but with the help of local cybersecurity experts, it’s easier to take control of your business’s digital safety. Let’s look at the most common cybersecurity pitfalls and how you can address them.

1. Failing to Implement MFA

One of the most significant cybersecurity mistakes SMEs make is not using multi-factor authentication (MFA) across their systems. Many businesses still rely on simple password protection, which is incredibly easy for cybercriminals to crack. In fact, weak or stolen passwords are one of the leading causes of data breaches. Without MFA, once a cybercriminal gets hold of an employee’s password, they have immediate access to your sensitive systems and data.

What is MFA?
MFA adds an additional layer of security by requiring users to verify their identity in two or more ways—typically by combining something they know (password) with something they have (e.g., a code sent to their phone) or something they are (biometrics).

The Risk for SMEs:
Without MFA, your business is vulnerable to attacks that could lead to the loss of sensitive data, financial theft, or costly downtime. Many SMEs mistakenly think they are "too small" to be targeted, but in reality, cybercriminals often focus on small businesses because they are seen as easy targets.

Recommendation:
Ensure MFA is implemented across all user accounts, especially for access to critical systems such as email, financial platforms, and cloud services. If you’re unsure where to start, consult with local cybersecurity experts who can guide you through the process and help secure your systems.

2. Ignoring Regular Updates and Patches

Another common mistake SMEs make is failing to keep their software and systems up to date. Cybercriminals often exploit vulnerabilities in outdated software to gain access to company data. These vulnerabilities are patched regularly by software vendors, but many businesses don’t apply updates promptly. By delaying updates, SMEs leave themselves exposed to attacks that could have been easily prevented.

The Risk for SMEs:
Outdated software provides an open door for hackers to exploit. This includes everything from operating systems and antivirus software to web browsers and plugins. Failing to update software also means missing out on security enhancements that can further protect your business from modern threats.

Recommendation:
Create a policy for regular software updates and patches. Automate the process whenever possible to ensure that updates are installed as soon as they’re available. For more complex systems, work with local cybersecurity experts like Mason Infotech who can manage the patching process for you, ensuring there are no gaps in your security defenses.

3. Underestimating Insider Threats

One of the biggest blind spots for SMEs is the risk posed by their own employees—either through malicious intent or, more commonly, human error. Insider threats account for a significant portion of data breaches. This could be as simple as an employee clicking on a phishing email, using weak passwords, or accidentally sharing sensitive information. Without proper cybersecurity awareness and training, your employees may unintentionally open the door to a cyberattack.

The Risk for SMEs:
Many SMEs focus their cybersecurity efforts on external threats, neglecting the dangers within their organisation. Human error, such as falling for phishing attacks or using unapproved apps (Shadow IT), is a common cause of data breaches. These mistakes can lead to financial loss, reputational damage, and legal issues.

Recommendation:
Invest in regular cybersecurity awareness training for your employees. Training should cover recognising phishing scams, using strong passwords, and the importance of following company security policies. Additionally, work with local cybersecurity experts to implement policies like role-based access control, which limits employee access to sensitive data on a need-to-know basis.

These three cybersecurity mistakes—neglecting MFA, delaying software updates, and underestimating insider threats—are all preventable. As an SME, you may not have the resources of a large enterprise, but that doesn’t mean you have to leave your business exposed to cyber risks. By addressing these common pitfalls and working with local cybersecurity experts, you can build a robust security posture that protects your company from a wide range of cyber threats.
