The retail sector has experienced transformational change with the introduction and widespread adoption of digital technology. The sector has seen an extreme level of transformation; from physical storefronts, through the early days of internet retailing, all the way up to the modern retail and eCommerce ecosystem. This transformation has required the adoption of new technology at each stage, with APIs the current foundational building block, enabling the necessary connections between retailers, consumers and the supply chain. However, given the resulting amount of personal identifiable information (PII) on offer, retail is an extremely attractive target for cybercriminals to exploit vulnerabilities for financial gain.
