Frequently Asked Questions.


The cyber threat landscape in Brussels and Belgium has undergone significant changes in recent years, reflecting global trends but also presenting unique challenges for local businesses. Here's an overview of the evolution and its implications:

Evolution of Cyber Threats:
  • Increased Sophistication: Cyber attacks have become more complex and harder to detect, often using advanced techniques like AI and machine learning.
  • Ransomware Surge: Belgium has seen a sharp rise in ransomware attacks, with a 300% increase reported in 2021 compared to the previous year.
  • Supply Chain Attacks: Targeting of supply chains has grown, affecting both large corporations and SMEs in Brussels' diverse business ecosystem.
  • IoT Vulnerabilities: As Brussels embraces smart city initiatives, the number of IoT devices has increased, expanding the attack surface for cybercriminals.
  • State-Sponsored Threats: Being the heart of the EU, Brussels faces elevated risks from state-sponsored cyber espionage and attacks on critical infrastructure.
Implications for Brussels Businesses:
Implication Description
Increased Cybersecurity Budgets Belgian companies are allocating larger portions of their IT budgets to cybersecurity, with an average increase of 25% in the past two years.
Regulatory Compliance Stricter EU and Belgian data protection laws (GDPR, NIS Directive) require businesses to enhance their cybersecurity measures and reporting processes.
Talent Shortage Brussels faces a cybersecurity skills gap, with over 3,000 unfilled positions in 2023, pushing businesses to invest in training or outsource security services.
Business Continuity Planning Companies are prioritizing robust disaster recovery and business continuity plans to mitigate the impact of potential cyber attacks.
Cybersecurity Insurance More Brussels-based businesses are investing in cyber insurance, with a 40% increase in policy adoptions since 2021.

To address these challenges, Brussels businesses should:

  1. Implement a comprehensive cybersecurity strategy that includes regular risk assessments and employee training.
  2. Adopt a zero-trust security model to protect against both internal and external threats.
  3. Leverage local expertise by partnering with Brussels-based cybersecurity firms familiar with the specific threat landscape.
  4. Participate in information sharing initiatives like the Belgian Cyber Security Coalition to stay informed about emerging threats.
  5. Invest in advanced threat detection and response technologies, including AI-powered solutions.

By understanding the evolving cyber threat landscape and taking proactive measures, Brussels businesses can enhance their resilience and protect their assets in an increasingly digital world.



In Brussels, the heart of European politics and business, SMEs face unique cybersecurity challenges. With limited resources, protecting against cyber threats can seem daunting, but it's crucial for business continuity and data protection. Here are effective strategies for Brussels-based SMEs to enhance their cybersecurity posture:

1. Leverage Local Resources and Initiatives
  • Brussels Security Hub: Take advantage of the Brussels-Capital Region's cybersecurity initiative, which offers free security scans and advice to local businesses.
  • Belgian Cybersecurity Coalition: Join this public-private partnership that provides resources and best practices tailored for Belgian businesses.
2. Implement Basic Yet Effective Security Measures
  • Use strong, unique passwords and enable two-factor authentication (2FA) across all accounts.
  • Keep all software and systems updated regularly to patch known vulnerabilities.
  • Encrypt sensitive data, especially when transmitting information over networks.
  • Install and maintain reputable antivirus and anti-malware software on all devices.
3. Train Employees on Cybersecurity Best Practices

Human error is often the weakest link in cybersecurity. Conduct regular training sessions to educate employees on:

  • Identifying phishing attempts and social engineering tactics
  • Safe browsing and email practices
  • Proper handling of sensitive data
  • The importance of adhering to company security policies
4. Develop and Enforce a Comprehensive Cybersecurity Policy

Create a clear, easy-to-follow cybersecurity policy that outlines:

  • Acceptable use of company devices and networks
  • Data handling and storage procedures
  • Incident response plans
  • Regular security audits and assessments
5. Utilize Cloud Services Wisely

Reputable cloud service providers often have robust security measures in place. By leveraging these services, SMEs can benefit from enterprise-grade security at a fraction of the cost. However, ensure that any cloud service used complies with EU data protection regulations, particularly GDPR.

6. Network Segmentation and Access Control

Implement network segmentation to isolate critical systems and data. Use the principle of least privilege, granting employees access only to the resources they need for their specific roles.

7. Regular Backups and Disaster Recovery Planning

Implement a robust backup strategy, including off-site or cloud-based backups. Regularly test your disaster recovery plan to ensure you can quickly restore operations in case of a cyber incident.

8. Collaborate with Local Cybersecurity Firms

Brussels is home to numerous cybersecurity companies. Consider partnering with a local firm for periodic security assessments or managed security services. Many offer scalable solutions suitable for SMEs.

9. Stay Informed About Local Cyber Threats

Follow updates from the Belgian Centre for Cybersecurity (CCB) and participate in local cybersecurity events and workshops to stay informed about emerging threats specific to the Brussels business environment.

10. Consider Cybersecurity Insurance

As a last line of defense, explore cybersecurity insurance options. Many providers in Brussels offer policies tailored to SMEs, which can help mitigate financial losses in case of a breach.

By implementing these strategies, SMEs in Brussels can significantly enhance their cybersecurity posture without breaking the bank. Remember, cybersecurity is an ongoing process, not a one-time fix. Regularly review and update your security measures to stay ahead of evolving threats in the dynamic Brussels business landscape.
