Cyber Security for SMEs UK: How to protect your company from threats

Some of the common threats, and what you can do about them

Here are some tips on cyber security for SMEs. UK small and medium-sized enterprises (SMEs) are increasingly becoming targets for cyber threats due to their often limited resources and potentially less robust security measures compared to larger corporations.

We have listed the common threats and offered some suggestions on how you can mitigate the risks.

Some prevalent cyber threats that SMEs often face include:

Phishing Attacks

Cybercriminals use deceptive emails, messages, or websites to trick individuals into revealing sensitive information such as passwords, financial data, or access credentials.


This malware encrypts files or systems, and attackers demand a ransom for decryption keys. SMEs might be particularly vulnerable as they may not have robust backup systems in place.

Insider Threats

These involve employees or associates intentionally or unintentionally causing harm by leaking sensitive data or compromising systems.

Supply Chain Attacks

SMEs may be vulnerable through their connections to larger companies, which could be targeted. Attackers exploit weak links in the supply chain to gain access to SMEs' networks.

Data Breaches

Theft or exposure of sensitive information can lead to financial loss, reputation damage, and legal repercussions for SMEs.

Weak Security Measures

Insufficiently protected networks, outdated software, and lack of regular security updates could make SMEs more susceptible to attacks.

To mitigate these threats, SMEs should consider implementing a robust cybersecurity strategy that includes:

Employee Training:

Educating employees about cybersecurity best practices and how to recognise potential threats.

Up-to-date Software and Patch Management:

Ensuring all software and systems are regularly updated to patch vulnerabilities.

Data Encryption and Access Control:

Protecting sensitive data through encryption and restricting access to authorised personnel only.

Regular Backups:

Keeping backups of critical data in separate, secure locations to mitigate the impact of ransomware attacks.

Firewalls and Antivirus Solutions:

Implementing and maintaining strong perimeter defences and endpoint security measures.
