4.1 zeroBS can determine test data as part of a customer order, hold it and use it to create the report.

4.3 The customer will not transfer any personal data to zeroBS unless absolutely necessary. Should zeroBS nevertheless have to process personal data as part of the fulfilment of the order, this process is deemed to be order data processing. In this case, the following order data processing agreement applies:

(1) Both parties shall observe the applicable data protection regulations, in particular those valid in Germany, and shall oblige their employees deployed in connection with the contract to maintain data secrecy in accordance with Section 5 BDSG, unless they are already generally obliged to do so.

(2) If the customer collects, processes or uses personal data on facilities provided by zeroBS within the scope of this contract, the customer warrants that he is authorised to do so in accordance with the applicable provisions, in particular those of data protection law, and indemnifies zeroBS against claims by third parties in the event of a breach. This also applies in the event that the customer sends the data to third parties using the services or makes them available for collection.

(3) Insofar as the data to be processed is personal data, this constitutes commissioned data processing (§ 11 BDSG) and zeroBS shall comply with the customer's instructions (e.g. to comply with deletion and blocking obligations). The instructions must be communicated in writing in good time

(4) The zeroBS may award subcontracts, but must impose the obligations corresponding to the prefix (order data management) on the sub-zeroBS.

(6) The zeroBS shall take the technical and organisational security precautions and measures in accordance with the Annex to Section 9 BDSG.

(7) The customer is generally not authorised to access the premises with the software application, the server and the operating software as well as other

system components of the data centre of zeroBS. This does not affect the access rights of the customer's data protection officer after written notification for the purpose of checking (§ 11 para. 2 BDSG) compliance with the requirements in accordance with the Annex to § 9 BDSG as well as zeroBS's other handling of personal data in the context of operation in accordance with the law and the contract.

4.4 Further use of know-how: The above provisions do not restrict the right of the contracting parties to further use ideas, know-how, concepts and procedures which relate to the contractual services and become general know-how in the course of the co-operation, provided that this does not infringe any property rights or the obligation to maintain confidentiality of confidential information of the other party or a third party.

The "mandate" is the customer's consent to the payee (zeroBS) to collect due receivables by direct debit and the instruction to his payment service provider (paying agent, the customer's bank) to honour the direct debit by debiting his payment account. The direct debit is initiated by zeroBS. The announcement of the direct debit (pre-notification) is made at the latest 3 working days before the direct debit is asserted, usually with the invoice. Collection by zeroBS takes place at the earliest 3 working days after the invoice date. The invoice will be sent to the customer by email to the email address provided by the customer. The customer must ensure that there are sufficient funds in the specified account so that the amounts due can be collected.

  • if the stress test is cancelled by the customer less than 7 days before the agreed date, 50% of the commissioned services will be charged
