Section 21 of the POPI Act requires that a written agreement needs to be entered into between an Operator and a Responsible Party (your business). As such, an oral agreement unfortunately is not POPI Act compliant. The written agreement needs to ensure that the Operator establishes adequate safeguards and security measures for and when processing the personal information of your clients.
Further, your business could be held liable by the Information Regulator for any breach by the Operator of the POPI Act. Our Template Data Processing / Operator Agreement is a ready to go, out of the box solution, for your business needs.
