The new Federal Act on Data Protection (nFADP) and the corresponding ordinance will come into force in Switzerland on 1 September 2023. All companies that process personal data which affects natural persons in Switzerland fall within the scope of the law and are equally affected.

The specialists of the Advisory IT & Digitalisation Team of Grant Thornton Switzerland/Liechtenstein can support you efficiently and straightforwardly due to their expertise in technical and legal issues in order to implement the new legal requirements in a timely manner. 

 

 

In almost every company today, business processes are based on the underlying IT infrastructure and the applications used. Experience shows that this also affects the individual offices of cantonal authorities and the associated audit activities of the supervisory bodies. Grant Thornton supports cantonal financial auditors and supervisory bodies in auditing complex IT infrastructures and IT processes, thereby creating increased transparency and audit certainty in an interwoven constellation between offices and auditors with various interdependencies.

 

 

SAP transformations can be complex, risky and often present unexpected challenges for organisations. A lack of strategy, limited resources, dependence on implementation partners and unclear architecture decisions often lead to delays and risks.

We know the challenges of SAP projects very well and are therefore able to manage projects in a targeted manner and accompany them successfully. With proven methods, in-depth expertise and a practice-orientated approach, we bring structure and strategy to the chaos and keep your back free.

 

Digitalisation and the increasing networking of business processes make companies more vulnerable today than ever before. Cyberattacks, data loss and system failures have become real threats that can cause not only financial damage but also reputational damage. 

Our Cyber Security Health Check helps you to identify vulnerabilities at an early stage, minimise risks and protect your IT landscape in the long term – before attackers become active.

 

In today’s digital world, cyber resilience is critical for all organisations, regardless of size.

Cyber attacks are becoming increasingly sophisticated and the impact of a cyber incident can be devastating. It is therefore essential to invest in a robust cyber security solution that gives your organisation insight and protects against the latest threats.
