Cybercriminals are increasingly targeting small and medium-sized businesses. Why? Because SMEs often lack security and manage valuable data. In this article, we discuss the main cyber threats to SMEs in 2025 and how you can prepare for them.
1. Phishing attacks are becoming more personalised
Phishing remains the number one attack vector. In 2025, we will see an increase in targeted emails specifically targeting your industry, employees or recent events.
What you can do: Run regular phishing simulations to raise awareness.2. Ransomware affects smaller and smaller businesses
Ransomware attacks are no longer the preserve of large organisations. Hackers are targeting vulnerable networks with minimal protection.
Prevention is better than cure: Implement daily backups, network segmentation and a vulnerability scan to reduce risks.
3. Shadow IT and insecure apps
Employees often use unsecured tools without the IT manager's knowledge. This increases the risk of data breaches.
Tip: Conduct a software inventory and establish clear IT policies. Tools such as Custodes help with this.
4. NIS2 and compliance requirements
New regulations such as the NIS2 directive set stricter requirements for digital security-also for SMEs.
How to respond: Use compliance tools to quickly identify which measures are mandatory.
5. Supply chain attacks
Cybercriminals attack suppliers to enter your organisation through the ‘back door’.
What helps: Ask suppliers about their security policies and conduct regular risk analysis.
Conclusion
2025 will be an important year for digital resilience. SMEs that proactively invest in cybersecurity - using tools like Custodes - are better protected against these growing threats.
