“Auditors and certified public accountants are required under Section 43 of the German Public Accountants Act (WPO) to maintain confidentiality, and as professionals bound by statutory secrecy under Section 203 of the German Criminal Code (StGB), they belong to the occupational groups subject to the highest requirements for the confidentiality of client data. Whether it’s a statutory audit, a special audit, or a due diligence review as part of a transaction: audit documentation, financial statements, and contracts must be exchanged securely between the firm, the client, and other parties involved.”
TeamDrive provides a zero-knowledge encrypted virtual data room for this purpose, with servers located in Germany.
Legal requirements for cloud use by auditors
Section 43 WPO obliges auditors to maintain confidentiality regarding all facts entrusted to them or that become known to them in the course of their professional activity. As professionals bound by statutory secrecy under Section 203 StGB, auditors and certified public accountants are additionally subject to a criminally sanctioned duty of confidentiality. Since the 2017 reform of Section 203 StGB, professionals bound by statutory secrecy may engage external service providers – such as IT and cloud providers – without committing a criminal offense, provided these providers are themselves contractually bound to confidentiality. TeamDrive provides a separate contract for professionals bound by statutory secrecy for this purpose.

With TeamDrive, you create a dedicated, zero-knowledge encrypted space for each audit, assign fine-grained access rights to clients, audit teams, and other parties involved, and always keep track of who accessed which document and when, thanks to the complete activity log.
