IT, Privacy & Cybersecurity

IT, Privacy & Cybersecurity

The world is changing at a rapid pace. New technologies, relationships and opportunities mean there are also new challenges, including in the field of law. However, we are not only on top of these developments, we are also looking far into the future. We identify bottlenecks, offer insights and come up with solutions. Our team serves a wide variety of organisations, from start-ups to listed companies, and from NGOs to international public law organisations.

IT

Our team advises and litigates in the IT legal field on a daily basis, in such matters as transactions for cloud services (SaaS, PaaS, IaaS), the implementation of ERP systems, privacy matters or custom software development. The team has extensive experience in resolving IT-related disputes, whether by mediation or arbitration, or before the public courts.

When it comes to suppliers, we advise IT companies ranging from software developers to cloud service providers, and from hardware suppliers to managed service providers. Our clients on the buyer side operate in a variety of sectors, and are strongly represented in the care/healthcare sector, research & education, and the public sector.

Privacy

The members of our team have postdoctoral qualifications in the field of privacy, and/or are certified in accordance with CISM (Certified Information Security Manager), CIPP/E (Certified Information Privacy Professional/Europe), CIPM (Certified Information Privacy Manager) and CIPT (Certified Information Privacy Technologist). They assist organisations in privacy compliance processes to ensure timely compliance with privacy legislation and regulations, advise organisations on cooperation and data-sharing, and assist organisations in the event of a data breach.

Managing a data breach is complex and requires specialised knowledge. For example, the scope of the data breach must be established as quickly as possible, statutory reporting obligations must be met in a timely manner, the effects of the incident on contractual agreements with third parties must be identified, and an investigation must be carried out to determine whether and how any damage can be recovered from third parties.

Cybersecurity

The greatest risk entrepreneurs face currently is that posed by cyber threats. De Clercq is an expert in the broader field of IT law, and has particular expertise in the area of cybersecurity legislation and regulations.

It goes without saying that we’re also happy to help you get ahead in this increasingly important area. Our team is on standby 24/7 for entrepreneurs who have been affected by a cyber attack or other major cyber incident, and will guide them throughout the whole process of managing the incident. Doing this requires both speed and expertise. Our team has a large network of forensic cybersecurity specialists and other consultants who can be called in if necessary.
