On the supplier side, we advise IT companies, ranging from software developers to cloud service providers and from hardware suppliers to managed service providers.

Our team members have completed postgraduate courses in privacy and/or hold certifications such as CISM, CIPP/E, CIPM, and CIPT. They assist organizations in privacy compliance processes to ensure timely compliance with privacy laws and regulations, provide advice on collaborations and data sharing, and support organizations in the event of a data breach.

Handling a data breach involves various complexities and requires specialized knowledge. Quick understanding of the extent of the data breach is crucial, compliance with legal reporting obligations must be timely, an assessment of the impact on contractual agreements with third parties needs to be conducted, and an investigation into whether and how damages can be recovered from third parties may be necessary.
