Globally, the increase in cyber-attacks and data breaches in the coming years has been predicted by reputable sources. The latest statistics from Cybersecurity Ventures project successful cyber-attacks could cost businesses over $10.5 trillion annually by 2025. In this context, information systems and software solutions have to change, as traditional practices, by incorporating security controls at later stages of development. 'Privacy by Design' (PbD) is attracting considerable resources, focus, and logically encouraging data protection as best practice applicable across the data lifecycle. However, the implementation of the PbD principle remains a challenge. Numerous developers cannot strike equilibrium between ‘functionality’ and privacy due to insufficient guidelines and resources. Many organizations with appropriate leadership have achieved higher levels within the boundaries of IT that effectively integrate PbD, while others are constantly trying to catch up. This paper aims to fill these gaps by incorporating different research outcomes, statistics, and best practices for incorporating privacy in information systems design practice. This contribution will assist IT practitioners in mitigating data breaches and adherence to the changing privacy laws which in the long run improve user confidence and data security in the systems being used
