• specific safeguards prepared by the competent federal body and communicated beforehand to the FDPIC; • standard data protection clauses previously approved, established or recognised by the FDPIC; and • binding corporate rules (BCRs) on data protection that were previously approved by the FDPIC, or by a foreign authority that is responsible for data protection and belongs to a state that guarantees adequate protection. Mechanisms or Derogations That Apply to International Data Transfers The FADP provides that personal data may not be disclosed abroad if this would seriously endanger the personality of the data subjects. Such a serious threat to the personality rights of the data subjects may arise if the exporting state does not have legislation that guarantees an adequate level of data protection. However, a transfer of data to such a state may be permitted if one of the foregoing conditions is fulfilled. Regarding the standard contractual clauses (SCCs) published by the EU Commission, the FDPIC formally recognised the SCCs for international transfers from Switzerland to third states, but only if certain changes are agreed to account for Swiss law (and the fact that Switzerland is not an EEA member state). For data transfers subject to the GDPR only, the non- amended SCCs may be used. Therefore, the parties should determine whether only the FADP or both the FADP and the GDPR apply to the transfer in question. The EU SCCs require a “transfer impact assessment” (TIA). This also applies to Swiss companies if they use the EU SCCs (under the GDPR as well as under the FADP). As part of a TIA, the Swiss data exporter must check in each specific case whether the laws of the recipient country regarding official access in the recipient country (eg, for the purpose of national security or criminal prosecution) and the rights of the data subjects are compatible with Swiss data protec - tion law and Swiss constitutional principles. In addition, Switzerland has recently implemented the Swiss-US Data Protection Framework (DPF). It

remains to be seen if the DPF will stand, and for now, many companies opt to use the SCCs in addition to relying on the DPF. Finally, the FDPIC has pointed out that internal com - pany data protection regulations – ie, BCRs – cannot be a substitute for the conclusion of a SCC if transfers are made outside of a group of companies subject to the BCRs. 3.6 Threat-Led Penetration Testing Swiss legislation does not currently provide for threat- led penetration testing (TLPT) requirements, except that FINMA expects banks and securities dealers to carry out regular penetration testing (per its Circular 2023/1 Operational Risks). In addition, Swiss finan - cial entities may be subject to DORA requirements if they operate within the EU or have connections with EU-based financial institutions or their clients. Likewise, Swiss companies affiliated with EU finan - cial entities that provide intra-group ICT services to their EU counterparts are also covered by DORA for these activities. Furthermore, DORA applies to Swiss ICT service providers as soon as they plan to offer their services to relevant financial entities within the EU. Finally, although Swiss data protection legislation does not expressly call for penetration testing, it can be mandatory to the extent it is a minimum security requirement in specific circumstances.
